DOI : 10.3390/rs9020120.
    Résumé : ALS-derived raster visualization techniques have become common in recent years, opening up new possibilities for subtle landform detection in earth sciences and archaeology, but they have also introduced confusion for users. As a consequence, the choice between these visualization techniques is still mostly supported by empirical knowledge. Some attempts have been made to compare these techniques, but there is still a lack of analytical data. This work proposes a new method, based on gradient modelling and spatial statistics, to analytically assess the efficacy of these visualization techniques. A selected panel of outstanding visualization techniques was assessed first by a classic non-analytical approach, and secondly by the proposed new analytical approach. The comparison of results showed that the latter provided more detailed and objective data, not always consistent with previous empirical knowledge. These data allowed us to characterize with precision the terrain for which each visualization technique performs best. A combination of visualization techniques based on DEM manipulation (Slope and Local Relief Model) appeared to be the best choice for normal terrain morphometry, occasionally supported by illumination techniques such as Sky-View Factor or Negative Openness as a function of terrain characteristics.

    Résumé : The use of Light Detection And Ranging (LiDAR) for archaeological purposes is becoming more prevalent in order to detect and to document remains located in forested areas. One of the main interests of airborne laser scanning is to put the archaeological information in their context, and to allow a better understanding of the relation between each item and its environment. This concept of archaeological landscape generally results in a too large amount of data to permit a manual analysis. This paper describes an approach for the automatic detection of elementary archaeological grazing structures, found in high concentration in some places of Auvergne (France). These elementary structures are generally connected, creating complex archaeological grazing sets. The detection process is based on the design of a model of an elementary grazing structure. The automatic detection is then carried out, based on the evaluation of the matching degree of each element with the model and on their belonging to complex archaeological grazing structures. The efficiency of the method is tested, by comparison with the manual digitalisation of an expert, on a restricted zone, and the results show that the success rate of the automatic detection reaches higher values than classical template matching approaches. The additional criterion, based on the belonging of each elementary structure to a more complex one, improves the detection success: In a complementary way, this approach offers new opportunities: it is also possible to detect complex structures with a template matching approach, if they contain some simple forms, that can be modelled.

    Résumé : We present a palaeoenvironmental study of the Castelló lagoon (NE Spain), an important archive for understanding long-term interactions between dynamic littoral ecosystems and human management. Combining geochemistry, mineralogy, ostracods, diatoms, pollen, non-pollen palynomorphs, charcoal and archaeo-historical datasets we reconstruct: 1) the transition of the lagoon from a marine to a marginal environment between ~3150 cal BC to the 17 th century AD; 2) fluctuations in salinity; and 3) natural and anthropogenic forces contributing to these changes. From the Late Neolithic to the Medieval period the lagoon ecosystem was driven by changing marine influence and the land was mainly exploited for grazing, with little evidence for impact on the natural woodland. Land-use exploitation adapted to natural coastal dynamics, with maximum marine flooding hampering agropas-toral activities between ~1550 and ~150 cal BC. In contrast, societies actively controlled the lagoon dynamics and become a major agent of landscape transformation after the Medieval period. The removal of littoral woodlands after the 8 th century was followed by the expansion of agrarian and industrial activities. Regional mining and smelting activities polluted the lagoon with heavy metals from the ~11 th century onwards. The expansion of the milling industry and of agricultural lands led to the channelization of the river Muga into the lagoon after ~1250 cal AD. This caused its transformation into a freshwater lake, increased nutrient load, and the infilling and drainage of a great part of the lagoon. By tracking the shift towards an anthropogenically-controlled system around ~750 yr ago, this study points out Mediterranean lagoons as ancient and heavily-modified systems, with anthropogenic impacts and controls covering multi-centennial and even millennial timescales. Finally, we contributed to the future construction of reliable seashell-based chronologies in NE Spain PLOS ONE |

(2016) « Fire history on the California Channel Islands spanning human arrival in the Americas », Philosophical Transactions of the Royal Society of London. B (1887–1895), 371 (mai). DOI : 10.1098/rstb.2015.0167.
    Résumé : Recent studies have suggested that the first arrival of humans in the Americas during the end of the last Ice Age is associated with marked anthropogenic influences on landscape; in particular, with the use of fire which, would have given even small populations the ability to have broad impacts on the landscape. Understanding the impact of these early people is complicated by the dramatic changes in climate occurring with the shift from glacial to interglacial conditions. Despite these difficulties, we here attempt to test the extent of anthropogenic influence using the California Channel Islands as a smaller, landscape-scale test bed. These islands are famous for the discovery of the ‘Arlington Springs Man’, which are some of the earliest human remains in the Americas. A unifying sedimentary charcoal record is presented from Arlington Canyon, Santa Rosa Island, based on over 20 detailed sedimentary sections from eight key localities. Radiocarbon dating was based on thin, fragile, long fragments of charcoal in order to avoid the ‘inbuilt’ age problem. Radiocarbon dating of 49 such fragments has allowed inferences regarding the fire and landscape history of the Canyon ca 19–11 ka BP. A significant period of charcoal deposition is identified approximately 14–12.5 ka BP and bears remarkable closeness to an estimated age range of the first human arrival on the islands.

DOI : 10.1002/jqs.2914.
    Résumé : Fluvial sequences from the late Pleistocene to the Holocene are exposed in Arlington Canyon, Santa Rosa Island, Northern Channel Islands, California, USA, including one outcrop that features centrally in the controversial hypothesis of an extra-terrestrial impact at the onset of the Younger Dryas. The fluvial sequence in Arlington Canyon contains a significant quantity and range of organic material, much of which has been charred. The purpose of this study was to systematically describe the key outcrop of the Arlington sequence, provide new radiocarbon age control and analyse organic material in the Arlington sediments within a rigorous palaeobotanical and palaeo-charcoal context. These analyses provide a test of previous claims for catastrophic impact-induced fire in Arlington Canyon. Carbonaceous spherular materials were identified as predominantly fungal sclerotia; ‘carbon elongates’ are predominantly arthropod coprolites, including termite frass. ‘Glassy carbon’ formed from the precipitation of tars during charcoalification. None of these materials indicate high-temperature formation or combustion. Charcoal and other materials in Arlington Canyon document widespread and frequent fires both before and after the onset of the Younger Dryas, recording predominantly low-temperature surface fires. In summary, we find no evidence in Arlington Canyon for an extra-terrestrial impact or catastrophic impact-induced fire.

    Résumé : Using a combination of pollen, non-pollen palynomorphs (NPPs) and charcoal particle stratigraphies from sediment cores from two sites, along with historical records, we reconstructed paleoenvironmental change in mid-coastal California. The San Antonio Creek section contains a discontinuous, Holocene-length record, while Mod Pond includes a continuous late Holocene record. Together the records allow for interpretation of most of the present interglacial. The longer record documents coastal sage scrub and chaparral dominated by woodland elements early in the Holocene to about 9000 yr ago, a potential decline in woodland communities with drying conditions during the middle Holocene to about 4800 yr ago, and an expansion of coastal sage scrub with grassland during the late Holocene. Evidence for climatic fluctuations during the last 1000 yr at Mod Pond is equivocal, suggesting that the Medieval Climate Anomaly–Little Ice Age had modest impact on the Mod Pond environment. However, evidence of significant environmental change associated with cultural transitions in the 18th–19th centuries is stark. Introduction of non-native plants, establishment of cattle and sheep grazing, missionization of the native population, changes in burning practices during the Spanish period and enhanced cropping activities during North American settlement worked together to substantially modify the mid-California coastal landscape in about a century's time.

    Résumé : Modena, founded by the Romans (183 BC), has always been conditioned by water in all its urban history. In the city, numerous archaeobotanical investigations have been carried out in order to reconstruct the natural landscape and human– environment interactions over time. During these investigations, four archaeological sites (two Roman and two medieval) have revealed deposits with a marked character of palaeobiocoenosis, largely resulting from the natural environment surrounding the sites, due to natural “seed rain”. These deposits are characterized by widespread evidence of plants related to water, constituting a valuable archive to investigate habitats which currently have become very rare and threatened, if they have not completely disappeared. The present paper aims to reveal the peculiarities of the Roman/medieval archaeocarpological floristic lists (through a comparison with the flora over the last two centuries in the area of Modena) and highlight the possible causes explaining the presence or the demise of several taxa, considering also the palaeoecological reconstruction of the environment in which they have been found.

DOI : 10.1016/j.quascirev.2015.01.017.
    Résumé : Using a novel combination of paleoecologic proxies including pollen, non-pollen palynomorphs (NPPs), macroscopic charcoal, and Spheroidal Carbonaceous Particles (SCPs), 5000 years of landscape change, fire history and land-use have been reconstructed from Dune Pond, Santa Barbara County, California. The pond was sensitive to Holocene regional climatic variability, showing different phases of lower (4600–3700 cal yr BP, 2100–700 cal yr BP, historical period) and higher (3700–2100 cal yr BP, 700–150 cal yr BP) local moisture availability. During this period the landscape was dominated by a coastal mosaic vegetation including dune mats, coastal scrub and salt marshes on the dunes and backdunes, with chaparral and oak woodland growing in the valley plains and foothills. Fire was intimately linked with such dominating mosaic vegetation, and the combination of wet conditions and the presence of nearby human settlement were a trigger favoring coastal fires for at least two periods: from 3100 to 1500 cal yr BP and from 650 cal yr BP until the 18th century. In both cases fire was an important tool to keep an open coastal landscape attractive to hunting wildlife. Finally, matching this varied range of high-resolution paleoecological proxies with historical records we could characterize the development of colonial transported landscapes following the Euro-American settlement of Santa Barbara. The introduction of livestock grazing by Spanish colonists favored erosive processes and the introduction of fecal-borne parasites in freshwater bodies, negatively impacted salt and brackish coastal marshes, and promoted the invasion of alien grasses and ruderals. This agro-pastoral landscape was consolidated during the American period, with a greater role for cultivation, the development of industrial activities and increased population. Despite negative environmental consequences such as the loss of native habitats, exotic land-uses and plants introduced during the historical period significantly contributed to the configuration of a cultural landscape which forms part of the cultural heritage of California.

    Résumé : Early human societies and their interactions with the natural world have been extensively explored in palaeoenvironmental studies across Central and Western Europe. Yet, despite an extensive body of scholarship, there is little consideration of the environmental impacts of proto-historic urbanisation. Typically palaeoenvironmental studies of Bronze and Iron Age societies discuss human impact in terms of woodland clearance, landscape openness and evidence for agriculture. Although these features are clearly key indicators of human settlement, and characterise Neolithic and early to Middle Bronze Age impacts at Corent, they do not appear to represent defining features of a protohistoric urban environment. The Late Iron Age Gallic Oppidum of Corent is remarkable for the paucity of evidence for agriculture and strong representation of apophytes associated with disturbance. Increased floristic diversity – a phenomenon also observed in more recent urban environments – was also noted. The same, although somewhat more pronounced, patterns are noted for the Late Bronze Age and hint at the possibility of a nascent urban area. High percentages of pollen from non-native trees such as Platanus, Castanea and Juglans in the late Bronze Age and Gallic period also suggest trade and cultural exchange, notably with the Mediterranean world. Indeed, these findings question the validity of applying Castanea and Juglans as absolute chronological markers of Romanisation. These results clearly indicate the value of local-scale palaeoecological studies and their potential for tracing the phases in the emergence of a proto-historic urban environment.

DOI : 10.1016/j.palaeo.2015.02.016.
    Résumé : Palaeoenvironmental studies allow the assessment of long-term human–climate–environmental interactions, and furnish valuable tools for the sustainable management of lacustrine ecosystems. A good example is the multi-proxy study of Lake Aydat's 19 m sedimentary core. Previous research revealed the role of climate and human activities on lake sedimentation, and identified two sedimentary units (6700 ± 200 to 3180 ± 90 and 1770 ± 60 cal. yr BP to present) separated by an erosive mass-wasting deposit (Lavrieux et al., 2013a). Pollen, non-pollen palynomorphs (e.g. fungal and algal spores, rotifer resting eggs), and diatom-based trophic reconstructions have been used to track the impacts of past land use on landscape evolution, vegetal biodiversity and water quality. Palaeoenvironmental data were also compared with local archaeo-historical datasets which allowed refined landscape reconstructions, especially for late Antiquity. The results obtained demonstrate that even Neolithic and Bronze Age human activities (between ca. 4600 and 4300 cal. yr BP and between ca. 3900 and 3500 cal. yr BP) had a discernible influence on catchment vegetation and lacustrine trophic dynamics of Lake Aydat, underlining the vulnerability of the ecosystem. Recurrent and complex models of past vegetation changes, phases of water nutrient over-enrichment and lake resilience were identified and related to grazing activities, but also to land use practises, which have been overlooked in Auvergne, such as mountain agriculture and hemp retting.

    Résumé : Transformation in technological patterns associated with the Middle-to-Upper Palaeolithic transition between 50 and 40 ka in Western Europe and their relationship with the Neanderthal and Anatomically Modern Human populations and behaviors are issues that continue to stimulate heated debate. In this article we use the Middle and Early Upper Palaeolithic archaeo-stratigraphic record from the Bordes-Fitte rockshelter (les Roches d'Abilly site, Central France), a Bayesian analysis of the ages obtained by accelerator mass spectrometry radiocarbon on ultrafiltered collagen and by luminescence on quartz and feldspar grains, to establish a timeline for material culture and sedimentary dynamic changes during the Middle-to-Upper Palaeolithic transition. Technology, refitting studies and taphonomy of lithic artifacts recovered in the geoarchaeological field units D1 and D2 permit to characterize 3 reduction strategies (Levallois, Discoidal and Châtelperronian blade) that took place between the cold Heinrich events 5 and 4. We discuss the implications of the results to characterize the end of the Middle Palaeolithic, and for distinguishing anthropogenic and non-anthropogenic factors in Middle-to-Upper Palaeolithic assemblage's variability.

    Résumé : This paper presents the use of soil charcoal analyses in order to identify the origin of a Nardus stricta grassland in a mountain system (Mont Lozere, France), and the use of environmental resources and the construction of a cultural landscape. Two opposing theories have been proposed to explain the origin of this open landscape (1450e1700 m altitude): natural or anthropogenic. The identification and radio- carbon dates of charcoal fragments of Fagus sylvatica, which were found in all of the pits located in the current grassland area and dated to 3695e3633 cal BC, demonstrate that this species has been present on the upper part of Mont Lozere since the Middle Neolithic. In addition, the presence of pioneer species (Betula, Salix, Corylus avellana), as well as mid- (Prunus cf avium) and late-successional species (F. syl- vatica) supports the hypothesis that the grassland contained both pioneer and mature phases of forest landscapes. The 14C dates, ranging from c. 4200 cal BC to 1200 cal AD, show that fire events occurred with different climatic influences. Fire events may correspond to one or several fires in a short period at the scale of the slope. Moreover, the dates coincide with the early and extensive human impact detected in the Massif Central and Mont Lozere. To explain the regular occurrences of fire events from the Middle Neolithic to the Central Middle Ages, agro-pastoral clearings have been postulated, as have been iden- tified in other areas in the Pyrenees and in the Alps. Such human impact may have been magnified, or least facilitated, by climatic conditions. Comparison with additional data (pollen, archaeology, ecology) demonstrates that this grassland area is not natural and corresponds to an ancient forested system that has been used and transformed by societies since the Neolithic, although climate change may have certainly affected this transformation. The aim of this research is to promote this cultural heritage in collaboration with the National Park of the Cevennes in order to protect its future.

DOI : 10.1111/bor.12025.
    Résumé : Numerous periglacial features (polygons, nets, soil stripes, ice-wedge pseudomorphs and sand-wedge casts, involutions) have been recorded in France by examining bibliographical sources and aerial photographs. These data show that a large part of France was affected by permafrost during the Pleistocene and only the southern Aquitaine Basin and Languedoc seem to have been beyond its maximum extent. The first OSL ages obtained from the aeolian infill of wedge structures indicate that at least two phases of thermal contraction cracking occurred in southwestern France between approximately 25 and 36 ka. Chronostratigraphical data from loess in northern France indicate that these episodes correspond to the formation of ice-wedge networks associated with tundra gleys. In the latter region, two additional permafrost episodes probably occurred during the Last Glacial, the older one corresponding to the end of Marine Isotope Stage (MIS) 4 around 60 ka and the more recent one to MIS 2 around 19-16 ka. Although stratigraphical data indicate that these episodes were relatively short (about one millennium), relict permafrost may have existed for longer periods in northern France.

    Résumé : The development of Neolithic lifestyle in the Western Mediterranean during the 6th millennium cal BCE is the consequence of the spread of populations from the Near East after successive stages of cultural remodelling. Despite a clear contribution of the Near-Eastern and Aegean Neolithic to the economic and technical changes that happened to the West, few is known here about their symbolic legacies, because of the scarcity of representations and ritual evidences associated to the earliest Western Neolithic contexts. Excavations at the rock shelter of Pendimoun (South-Eastern France) yielded the first anthropomorphic stone sculpture from the Western Mediterranean Neolithic (Early 6th millennium cal BCE). Using both carving and painting techniques, it represents a rather realistic human face which is a unicum within the Western Mediterranean and European frames. After having described the shaping and colouring details of the mask, the authors here deal with its possible social significances and cultural connections.

    Résumé : A palaeoenvironmental study of a palaeochannel within the lower alluvial floodplain of the Allier River, France, has been carried out at a high temporal resolution. Research was based upon a multi-proxy approach using different sedimentological (magnetic susceptibility, sediment texture and loss on ignition) and palaeoecological (pollen, non-pollen palynomorphs (NPPs), diatoms – indicators). The palaeochannel was dated from six radiocarbon dates and spans from the second to the eleventh century AD. The cultural landscape history of this floodplain and the progressive hydrological disconnection of the palaeochannel between the Antiquity and the early Middle Ages could be reconstructed according to several characteristic environmental phases. Co-inertia analysis linking pollen, NPPs and diatom corroborated the significant co-structure of these proxies and allowed to distinguish functional palaeoecological groups in terms of landscape openness, on-site aquatic and hygrophilous vegetation, riparian woodland, soil moisture and grazing pressure. Results obtained underpin the importance of grazing as a major agent of landscape change in floodplains, especially since the ninth century AD, when the clearance of the riparian woodland is attested. Gallo-Roman and Late-Antiquity land-use systems, on the contrary, allowed for the preservation of riparian fluvial landscapes.

DOI : 10.1111/boj.12166.
    Résumé : This work provides a tool whereby the needle remains of native, south-western European Pinus spp. can be easily identified from species-specific epidermal features. To construct this tool, the needles of P. uncinata, P. sylvestris, P. nigra, P. pinaster, P. pinea and P. halepensis were gathered across the Northern Hemisphere range of each taxon and compared with non-indigenous trees growing in two South Australian Botanic Gardens. Three needles from each of these species were taken from three adult trees growing at three different localities. Light microscopy was used to observe the key epidermal and stomatal features of the needles. To improve interpretation, additional scanning electron microscopy samples were prepared. Epidermal features, including variation in the diameter of the epistomatal chamber aperture (pore), are described. A taxonomic key based on the size, shape and arrangement of the subsidiary cells of the stomatal complexes was constructed. This key enables the identification of pine needle fragments at the species level (except those belonging to the group P. gr. nigra-uncinata). Despite their overlapping range, pore size was helpful in distinguishing between P. nigra and P. uncinata and between three groups of species. Isolated stomata were also observed. Cluster and discriminant analyses of stomatal variables described in earlier studies were performed. Overlap in guard cell variables hampers species-level identification of isolated stomata. Species discrimination is improved if groups of ecological affinity are considered.

    Résumé : This study investigates water and land usage in the territory of La Carència, an Ibero-Roman city located near Turís (Valencia, Spain) in Eastern Iberia. The outstanding political importance of La Carència during the Iberian Iron-Age period is attested by its large size, the monumental character of its structures and on-site finds. Multidisciplinary and micro-regional landscape work at its territory documented significant differences between the Iberian and the Roman settlement patterns, which are attributed to the distinct agricultural production and water management systems of each period. While Iberian sites are more related to the agricultural exploitation of flat, dry land for which water sources, such as natural springs, were probably used, Roman sites seem to be associated with more productive soils that take advantage of flooding areas and the drainage of water accumulation zones. Such different agricultural preferences based on large-scale water management are documented for the first time in the Iberian Peninsula and they attest to the great potential of multidisciplinary landscape archaeology to address past land-use practices.

    Résumé : Mont Lozère, located in the French Massif Central region, provides an exceptional context in which to research the impact that charcoal production and metallurgy had on woodlands, along with the role that these activities played in changing the mountain landscape. This study provides an insight into the land use, forest management methods and metallurgical practices in the area during the Middle Ages (11th to 15th centuries). Medieval charcoal burning platforms, archaeological remains that have often been neglected in the past as a source of historical information, along with nearby smelting sites, were identified, sampled and analysed. In this paper, spatial analyses, radiocarbon dating and anthracological and dendro-anthracological studies have been combined in a unique manner. The results reveal that charcoal burners practiced beech coppicing, where the species and diameter of wood used remained the same over a period of four centuries. It is proposed that this form of metallurgical forest management be considered an early example of a sustainable utilisation of natural resources.

(Environmental History of European High Mountains). DOI : 10.1016/j.quaint.2013.10.048.
    Résumé : The Countrasts Bog (1400 m a.s.l.), located in the western part of the Mont Lozère medium mountain, has been the object of an interdisciplinary study combining multiproxy analyses which includes pollen, non-pollen palynomorphs (NPP), macrocharcoal particles, sedimentology and geochemistry, with archaeological and archaeobotanical data. The high temporal resolution of the palaeoenvironmental study, with an average resolution of 40 years between samples, allows us to trace the landscape dynamics for the last 2000 years at a micro-regional scale. During the Roman Imperial period (ca. 1st–3rd centuries AD) local agropastoral activities were moderate, whereas metallurgical activities developed in the region as attested by geochemical records. Later, during Late Antiquity and Early Medieval periods (ca. 3rd–10th centuries AD), agropastoral activities increased and human impact produced major changes in local mire dynamics with the replacement of birch wooded bogs by sedge communities. During the High Middle Ages (ca. 10th–13th centuries AD), a complex system of land uses was established, based on different activities including ore smelting, forestry and agropastoralism, attested by pollen, NPP and geochemistry data, as well as by archaeological, archaeobotanical and historical evidence. Since the Late Middle Ages (ca. 14th century AD), local metallurgical activities and forestry management decline have coincided with the expansion of grazing in uplands. This new land use favored the expansion of upland grasslands and heathlands and triggered the establishment of an open-landscape during the Early Modern Period (ca. 15th–18th centuries AD). At the end of the 19th century and the 20th century, agropastoral activities declined while reforestation was carried out.

    Résumé : Pollen, non-pollen palynomorphs (NPPs), and charcoal particle stratigraphies are used to determine environmental change at Glenmire, Point Reyes Peninsula, northcentral coastal California, over the last c. 6200 years. Pollen was not preserved in early Holocene sediments when climate was drier than present. However, groundwater tables rose after c. 6200 cal. BP, allowing for greater subsequent preservation of organic matter. Middle and late Holocene environments were a mosaic of vegetation types, including mixed conifer forest with coastal scrub grassland prior to c. 4000 cal. BP. Subsequently, hardwoods such as alder (Alnus) and coastal scrub (e.g. Artemisia, Baccharis) expanded until c. 2200 cal. BP, followed by tanoak (Lithocarpus densiflorus), Douglas fir (Pseudotsuga menziesii), and coast redwood (Sequoia sempervirens). With increasing amounts of oak (Quercus), this mosaic of vegetation types continued to dominate until the arrival of Euro-Americans in the early to mid-1800s. The fire history is probably tied closely to human settlement, since natural ignitions are rare. Elevated charcoal amounts coincide with increased sedentism of the native populations by about 3500 cal. BP. Increased sedentism may have caused a more intense and constant use of the coastal environment around Glenmire. For the most recent centuries, we compared historical records of explorations, Spanish Mission establishment, consolidation of the native Coast Miwok population, ranching by Mexican nationals, and dairying by Americans at the height of California’s gold rush with the paleoecological record. The Glenmire record thus documents changing fire use following the ad 1793 fire suppression proclamation; declines in native forest species; introductions of non-native species, including those associated with livestock grazing and land disturbance; and an increase in coprophilous fungi (NPPs) associated with the presence of large numbers of sheep and cattle, among other changes. During the historical period, the sedimentary record of historical fires closely matches the nearby fire-scar tree-ring record.

DOI : 10.1016/j.quaint.2012.04.041.
    Résumé : Using an interdisciplinary methodology based on pedoanthracology, palynology and sedimentary charcoals, landscape transformation in the Pyrenees mountains during the Holocene is analyzed, with special attention to altitudinal variation in the treeline. The data sources were eight soil profiles on a transect at 2000e2600 m a.s.l. and a sedimentary record extracted from a very nearby peat bog at 2247 m a.s.l. The combination of three different proxies permits a more viable and qualitatively complementary data set, making it possible to better interpret the vegetation dynamic in this space through the Holocene. Analysis of the data showed that the Pyrenees landscape has undergone important changes during this period. The changing treeline is a good example. There is evidence of the decisive role of fire in the configuration of this landscape. Finally, this study shows that herding and agricultural uses over thousands of years in the study area have had a determining influence on the current configuration of the territory, equal to or more important than climatic factors.

    Résumé : Le déterminisme est un mode de raisonnement établissant un lien de causalité systématique et à sens unique entre un fait et la ou les causes à l’origine de ce fait. Ainsi, dans toute circonstance où la cause est avérée, le fait doit se produire. A l’inverse, l’absence de la cause interdit l’existence du fait. Il ne peut y avoir aucun hasard. On parle de déterminisme physique ou naturel dans le cadre des relations entre l’homme, les sociétés humaines et leur environnement naturel. La discipline scientifique qui a été la plus marquée par les débats autour du déterminisme physique est sans conteste la géographie, dont l’objet est de comprendre les modalités et les facteurs de l’inscription de l’homme et de ses activités à la surface de la terre et la manière dont en naissent des territoires. C’est sa position d’interface, dont le compas a certes bougé depuis l’émergence de la géographie au 19e siècle, qui explique l’importance des débats qui n’ont cessé d’animer la discipline relativement à la place à accorder au milieu physique, à la nature dans l’explication des faits humains. Comprendre ces débats et tenter de se positionner par rapport à cette question suppose tout d’abord de les replacer dans leur contexte historique, avant de montrer la complexité et l’actualité de cette question. Pour cette introduction au numéro spécial de la revue Mémoire d’Ardèche et Temps Présent consacré à la géologie ardéchoise, nous avons choisi nos exemples dans une acception très large de la géologie, voire au-delà du champ de cette discipline pour englober les diverses composantes naturelles de l’environnement qui forment système, et dans le but premier de faire saisir l’étroit entremêlement des causes, naturelles et anthropiques, qui régissent l’organisation et la dynamique de l’espace des sociétés.

DOI : 10.1177/0959683613484616.
    Résumé : A 19-meters-long sedimentary record that was retrieved in Lake Aydat (French Massif Central) covers the last 6700 yrs at a high-resolution. A multi-proxy approach (density, magnetic susceptibility, XRF, Rock-Eval analyses, pollen and non-pollen palynomorphs analyses and historical archives study) was used to characterise and tentatively propose a model of the sedimentation. The important deposition rate results from the narrow and incised fluvial valley dammed by a lava flow ca. 8550 years ago. Two contrasted periods of sedimentation (6700±200 - 3180±90 cal. BP, and 1770±60 cal. BP- now) are characterized. The lower unit (mid-Holocene) displays a fine and regular lamination and holds a single, major, flood deposit. This unit is capped by an erosive mass wasting deposit triggered ca. 1770±60 cal. BP. The upper unit (late-Holocene) is made of organic rich and fine grained faintly laminated sediment, with numerous interbedded flood deposits (56 events) and layers resulting from blooms of diatoms. The sedimentation was principally controlled by climatic forcings (solar activity) until ca. 1100 cal. BP, accompanied by detritic events linked to human activities around the lake. Then, a more detrital input attested by numerous and recurrent flood deposits can be linked to the intensification of a persistent anthropogenic impact on the catchment. Two phases of lake eutrophication are highlighted: a first phase between 1200-1130 cal. BP, as a result of increased anthropogenic pressure, and the current phase that could have started ca. 150 cal. BP.

    Résumé : Multi-proxy palaeoenvironmental studies are very important for the development of sustainable management strategies for ecosystems and modern landscapes. Analysing the relationship between societies, climate and environments through time, these studies contribute to define adequate policies and strategies for socio-environmental management, protection and legacy. Two complementary case studies- Aydat lake and Espinasse fen - from the south of the Chaîne des Puys (Auvergne, Massif Central, France) are presented. The analysis of these sedimentological records (both lacustrine and peat) follows a multi-proxy approach combining abiotic and biotic palaeoindicators (density, magnetic susceptibility, X-Ray Fluorescence spectrometry, Rock-Eval, pollen, non-pollen palynomorphs, molecular biomarkers). Aydat lake and Espinasse fen analyses were performed following a high spatio-temporal resolution. Results underline that long-term models of detrital input and eutrophication correspond to complex patterns with early and recurrent phases of human-induced ecological disturbances. They also evidence the existence of diversified long-term land use systems (deforestation, grazing, agriculture, hemp culture and retting) that provide fresh insights into the understanding of present-day mountain environments. This history between diversified human activities and hydrosystems responses must be taken into account for the construction of accurate retrospective and prospective model simulations of hydrosystem functioning.

This application has been twofold: archaeological research has employed GIS analyses, photogrammetrical modelling of past landscapes and multispectral imagery analysis. Scientific dissemination has been enhanced by the use of aerial photogrammetry but 3D virtual modelling was also employed to develop a hypothetical reconstruction of the city walled area. In general the application of digital methodologies benefited archaeological analysis and, at the same time, helped developing the heritage value of both site and territory.

    Résumé : This paper presents a geoarchaeological study of Middle and Upper Palaeolithic (Châtelperronian, Aurignacian and Solutrean) occupations preserved at the Bordes-Fitte rockshelter in Central France. The lithostratigraphic sequence is composed of near-surface sedimentary facies with vertical and lateral variations, in a context dominated by run-off and gravitational sedimentary processes. Field description and micromorphological analysis permit us to reconstruct several episodes of sediment slope-wash and endokarst dynamics, with hiatuses and erosional phases. The archaeostratigraphic succession includes Châtelperronian artefacts, inter-stratified between Middle Palaeolithic and Aurignacian occupations. Systematic refitting and spatial analysis reveal that the Châtelperronian point production and flake blanks retouched into denticulates, all recovered in the same stratigraphic unit, result from distinct and successive occupations and are not a 'transitional' Middle to Upper Palaeolithic assemblage. The ages obtained by 14C place the Châtelperronian occupation in the 41-48 ka cal BP (calibrated thousands of years before present) interval and are consistent with the quartz optically stimulated luminescence age of 39 ± 2 ka and feldspar infra-red stimulated luminescence age of 45 ± 2 ka of the sediments. The Bordes-Fitte rockshelter sequence represents an important contribution to the debate about the characterization and timing of the Châtelperronian, as well as its affinities to earlier and later industries.

    Résumé : The Chaine des Puys is a great collection of extinct volcanoes that cover the Hercynian basement and belongs to the Auvergne Volcanoes Natural Regional Park. Both the sedimentary record and the historical archives of this area are numerous. However, the cores studied hitherto do not offer a good knowledge of the historical dynamics because most of the wetlands have dried out during historical times, causing gaps in the sedimentary record and pollen oxidization. Moreover, all the studied cores are located on the crystalline basement or on an old volcanic one predating the Chaine des Puys. Thus they do not directly provide information about the volcanoes. This article presents the only core obtained from a site, a small maar, located on a volcano. The sequence is short but does not have the same sedimentary gaps as the others. Owing to physical (grain size), chemical (C, N, P, K, Ca, Mg, N-NO3, N-NH4), palaeoecological (pollen and non-pollen palynomorphs) and historical analyses, this study gives a more precise recording of the landscape changes during the last 500 years in the volcanic area and contributes to the knowledge of the Chaine des Puys landscape. It illustrates the mobility of the historical landscape, in particular the progression and regression of the forest and the erosive crises related to more intensive grazing activity. The observations are linked with the social and economical changes, especially with the consequences of the French Revolution and the rural depopulation. This landscape history gives data about the direction of changes to the landscape preservationists. They demonstrate that even if the Chaine des Puys landscape looks natural, it has been shaped by a very specific socio-economical system inherited from the Middle Ages. These aspects could be integrated in a management plan. (C) 2011 Elsevier Ltd and INQUA. All rights reserved.

DOI : 10.1007/s00334-012-0351-5.
    Résumé : Estanilles peat bog, located in the northeastern Iberian peninsula,was studied to determine the anthropogenic changes in the landscape over the past seven millennia. The pollen diagram and sedimentary charcoal analyses from this site permit us to reconstruct the landscape changes in an area of both Mediterranean and Atlantic influence. In addition, Montarenyo ombrotrophic peat bog was studied to strengthen the analysis of data from more recent centuries. This paper attempts a reconstruction of historical cultural landscapes using two complementary palaeobotanical proxies (pollen and charcoal) in high mountain environments. The macroscopic charcoal record shows a fire signal since 7500 cal. B.P. However, the relationship between fire frequency and human impact is not always linear. This divergence is linked to fuel availability and fire activity. Fire has been used repeatedly to clear ground and to maintain open areas, and has been a key tool for the management of these high mountain areas. The intensity of use of the landscape implies the expansion of agricultural areas into higher altitudes, including cereal cultivation above 2,200 m a.s.l., during the Middle Ages. The first clear human influence detected in the pollen percentage data is recorded between 6000 and 7000 cal. B.P. and, until present times, the greatest changes in vegetation and landscape history occurred during periods of particular specialization in socioeconomic activities during the Middle Ages.

DOI : 10.1016/j.paleo.2010.12.023.
    Résumé : The study of macroscopic charcoal particles from peat bogs has led to a better understanding of climate, vegetation and fire history, and human impacts. To determine the relationship between human activities and the role of fire events in vegetation change during the last 3300 cal yr BP, we present the results of a multiproxy approach based on the analysis of sediment characteristics, sedimentary charcoal, organic matter and pollen, as well as historical sources. This multi-proxy research permits high resolution palaeoenvironmental and fire history reconstruction of a mountain area located in the southern central Pyrenees (Spain). In the Pyrenees, fire is typically attributed to human activities since the beginning of the Bronze Age and may be correlated with slash-and-burn cultivation, metallurgy and pasturing activities. The data indicate a good linkage between high fire signals and Poaceae and Cerealia pollen, which reveals the impact of agro-pastoral practices. This study also shows two periods, 2900–2650 cal yr BP and 1850–1550 cal yr BP, for which higher frequencies of fire occurred, suggested by high arboreal pollen (AP) concentrations, and confirming the need for arboreal biomass to sustain fires. From the beginning of the Middle Ages, it seems that a change occurred in the anthropogenic use of fire, from a tool for agro-pastoral forest clearance to a means of maintaining open spaces.

    Résumé : New pollen analyses from four peat bogs and fens located on the plateau de Millevaches (Limousin, French Massif Central) are compared with one peat sequence situated at lower altitude in the northern Limousin (Mont d'Ambazac). This study, which is supported by eleven accepted AMS radiocarbon data, was undertaken to consider changes in regional vegetation from the beginning of the Holocene and to provide a first reconstruction of land-use history. A singular vegetation history characterizes the "plateau de Millevaches" from the center of the French Massif Central such as the simultaneous start of Corylus and Quercus dated from ca. 10560-10150 cal. BP (ca. 8550-8200 cal. BC). The composition of the forest cover remained largely unchanged with a large supremacy of Corylus in the regional vegetation until ca. 8050-7650 cal. BP (ca. 6100-5700 cal. BC) when the decline of Corylus was synchronous with the expansion of Quercus. The diversified oak woodlands were rapidly filled by Tilia, and pollen data indicate early Neolithic farming around 6600-6500 cal. BP (ca. 4600-4500 cal. BC). The installation of Fagus, which is dated about 5660-5300 cal. BP (ca. 3700-3400 cal. BC), occurs nearly 700 years later than in neighbouring Auvergne. The first oak and beech forests spread after ca. 4800-4400 cal. BP (ca. 2850-2450 cal. BC), and Fagus constitutes the dominant arboreal taxa in the regional vegetation only since ca. 3900-3550 cal. BP (ca. 1930-1530 cal. BC). While climatic factors may have played a major role in its delayed installation, these new pollen analyses provide the first pollen evidence of an anthropogenic factor particularly for the late Neolithic - early Bronze Age transition when increased human pressure (woodland clearances and presence of agricultural and grazing indicators) is evidenced. Different stages related to human activities are shown for the following periods. According to the pollen data, between ca. 2350-2100 cal. BP (ca. 400-150 cal. BC), the second Iron Age, and more particularly, the 4th-2nd centuries BC, represents an important threshold in the shaping of this medium mountain cultural landscape. Large beech-oak forest clearances are related to an important agropastoral extension which continues to increase during the beginning of the Roman period.

    Résumé : The study of a set of relict landslides in the Tertiary basin of Puy-en-Velay (Massif Central, France) provides information about the types of landslide that affect a part of the hillslopes and the predisposing factors controlling their pattern. Two clusters of landslides were defined, located in similar morphostructural contexts, but characterised by basaltic covers of different ages. The first factor controlling pattern was lithological, in particular the occurrence of two sandy-clay geological formations. One, 'Sables de la Laussonne', is an Oligocene formation, and the other corresponds to the sandy-clay fraction of a Quaternary formation. The second factor was the age of the basaltic cover, which controls the degree of catchment dissection. The ‘old’ catchments are most strongly widening, with a more differentiate topography than younger ones, and the density of relict landslides was greater in these catchments. The main type in the set of relict landslides seems to be complex slides with a rotational component at the top and a slow-moving earthslide making up the body. So far we cannot advance any firm hypothesis about the kinetics of these landslides. These relict landslides constitute major processes underlying basaltic scarp back-tilting in the basin and are a key factor in catchment geomorphology development.

DOI : 10.1177/0959683610386820.
    Résumé : Superimposed on the long-term climate variability attributed to orbital forcing, there are other modes of variability covering timescales from interannual to millennial throughout the Holocene. Their signatures in climate proxy archives can differ substantially because of their lower magnitude and regional diversity. However, if identified they can yield better understanding of the physical mechanisms regionally linking causes and effects. Here we describe a high-resolution record of organic matter accumulation in the sediments of Burg lake (Pyrenees, NE Iberian Peninsula), as assessed using loss on ignition (LOI), and compare it with the ice rafted debris (IRD) indexes from the North Atlantic. The LOI record indicates two main phases in the water body, a lacustrine phase as a shallow lake and a palustrine phase as a fen. The latter covers the period 2600–7200 cal. yr BP and within it there is a high coherence between LOI and IRD, which indicates submillennial climate fluctuations in the Pyrenees that can be related to the North Atlantic influence. The Burg’s LOI record suggests wetter (and occasionally colder) situations in the Pyrenees during high IRD in the Atlantic (Bond oscillations). These fluctuations would likely affect the snow covered period in the mountains (winter and spring seasons) the most, the period in which Atlantic westerlies currently have higher influence on precipitation over the Pyrenees. These climatic oscillations could have favoured Abies penetration during the mid Holocene, as evidenced by increased pollen percentages of this taxon during low IRD values (drier conditions). The pollen record also suggests potential relationships between climate and human activity as early as at mid Holocene, as human-related cereals increase during all the low IRD periods. The human signature (charcoal, cereals) becomes particularly evident at around 2800 cal. yr BP; in this oscillation Pinus overtake Abies in the conifer response to low IRD.

    Résumé : This article uses a method that combines pedoanthracological and pedo-archaeological approaches to terraces, complemented with archaeological pastoral data, in order to reconstruct the history of ancient agricultural terraces on a slope of the Enveitg Mountain in the French Pyrenees. Four excavations revealed two stages of terrace construction that have been linked with vegetation dynamics, which had been established by analyses of charcoal from the paleosols and soils of the terraces. Pedo-archaeological descriptions of these terrace soils reveal their ancient origins and their long-term use. Their chronology was established by radiocarbon dating of single charcoal fragments and charcoal lenses originating in the paleosols. Combining radiocarbon dating with pedo-archaeology resulted in a more reliable chronology. Moreover, the Bronze Age was found to be a crucial period in the history of land-use. This study also highlights the role of fire in the construction of this land-use pattern.

    Résumé : The framework of the oval barn of La Rivière farm, at Saint-Eloy-les-Tuileries in Corrèze, has been dated by dendrochronology in the context of an operation of preservation that took place in 2007 and 2008. The analysis shows that the 21 dated timbers are chestnut wood cut down during the winter of 1569. This set of timbers provides a unique source of information on the management of Limousin chestnut woods for a very poorly documented period, and the interpretation of these tree ring archives in an archaeo-environmental perspective is contemplated. In 2008, this project is integrated into a CRP supervised by Géolab, that already includes a chapter about the recent history of Limousin chesnut woods (CRP 'Geohistory and geoarchaeology of Limousin timberlands'). The growth of the barn's beams is compared to that of current chestnut trees representing the three types of stands available today in Limousin: the coppice, the forest and the orchard. The aim is to discover in which kind of wooded lands the beams have been cut. The results indicate that the barn's timbers probably come from own-rooted trees which grew in a forest environment and were felled on a fairly wide area. The archaeo-environmental potential of ancient timbers sampled for the dating of buildings is also discussed.

    Résumé : La porte Bécharie et l’hôtel Clédat sont situés à l’entrée de la vieille ville d’Uzerche. Classés au titre des Monuments Historiques le 6 mai 1907, les bâtiments font actuellement l’objet d’un projet de sauvegarde. L’intérêt que présente cet ensemble architectural a conduit le Service régional de l’Archéologie (SRA) du Limousin à prescrire une étude préalable qui, confiée au bureau Hadès, a associé une recherche historique, une analyse archéologique des élévations, des sondages et des datations par dendrochronologie. L’évolution des constructions peut se décomposer en neuf phases comprises entre le début du XIVe et le XXe siècle. L’aménagement du site étudié débute avec l’établissement d’une chaussée. Il se poursuit avec la construction d’une porterie (peut-être une tourporte flanquée d’une courtine). Ce dispositif défensif pourrait correspondre à une extension de l’enceinte urbaine d’Uzerche, intégrant un faubourg au cours de la période médiévale. Deux édifices sont ensuite adossés (dont l’un est précisément daté de l’année 1366) mais leurs fonctions primitives demeurent inconnues. L’ensemble subit une importante démolition, probablement à la fi n du XIVe siècle. Lorsque les constructions sont relevées au XVe siècle, la porte et l’un des édifices pourraient appartenir aux Pradel, se disant alors seigneurs de la porte Barrachaude. L’autre édifice, celui de 1366, est restauré entre 1465 et 1530. Il est peut-être, à ce moment-là, la propriété de l’un des membres de la famille Clédat. Le contexte des guerres de Religion entraîne une seconde phase de démolition. Lors des reconstructions du début du XVIIe siècle, les bâtiments sont réunis en une seule propriété, vraisemblablement par la famille Clédat qui, de la bourgeoisie marchande d’Uzerche, intègre alors la noblesse. Les phases ultérieures correspondent surtout à des aménagements.

    Résumé : Dans le Massif central, les têtes de bassin (ordre Strahler 3-4 et inférieur) sont un domaine encore peu investi pour l’étude des flux hydro-sédimentaires liés aux fluctuations environnementales quaternaires. Le système hydrographique naissant recèle pourtant d’intéressantes archives sédimentaires, à l’échelle au moins des temps postérieurs au dernier glaciaire. Motivé par les observations préliminaires effectuées ces dernières années dans le massif du Mézenc (Velay oriental, bassin supérieur de la Loire), le programme WRACC, financé par l’Etablissement Public Loire et le FEDER, se propose d’aborder l’étude de ces dépôts et de leur environnement sous l’angle d’une approche géoarchéologique pluridisciplinaire. La prospection est en cours, et s’appuie sur des coupes naturelles ainsi que sur l’ouverture de tranchées en travers d’un fond de vallon (Champetienne) où se sont concentrées nos investigations. Les données analytiques ne sont pas encore disponibles. Il est cependant possible, grâce aux observations stratigraphiques et aux premières datations obtenues, de poser quelques jalons. A l’échelle de l’Holocène au moins, les cours d’eau semblent avoir fluctué dans leur fond de vallon sans progrès de l’encaissement, alternant phases de stockage et de déstockage. La forme des chenaux successifs et le gabarit des matériaux les remblayant témoignent des fluctuations corrélatives du style fluvial et de la compétence. Les séquences débutent généralement par une nappe alluviale très grossière d’âge indéterminé témoignant d’un système de forte énergie. Le 4e-5e siècle après J.-C. semble marquer le terme d’une phase de stabilité avec remaniement des horizons pédologiques et de la végétation. Après cette vigoureuse phase de détritisme, la période stable allant des 8e-9e siècles au 15e siècle est enfin suivie par une crise érosive de faible énergie à l’Epoque Moderne, où la part respective des forçages naturels (PAG) et anthropiques peut être plus particulièrement discutée.

    Résumé : In the Eastern Massif Central, new research programs are dealing with the landscape evolution since the Late Glacial and during the Holocene (AGES and WRACC projects). In this context, a reconstruction of climatically and anthropogenically driven palaeoenvironments is in progress for the last 7,000 years. This palaeoenvironmental study of peatlands and archaeological remains focuses on an area still poorly documented: the Mezenc massif and the Ardèche mountain range, and particularly on the Béage volcanic plateau (Eastern Velay, Massif Central). The plant macrofossil analyses of a 5.5 meters long core, from the La Narce peatland on the Béage plateau (1,235 meters a.s.l.), revealed an excellent preservation of organic matter so to allow high-resolution reconstruction of environmental change. The La Narce peatland is located in a little catchment area (0.13 squared kilometres), at the interface between basaltic lava flows and the Velay granitic substratum. The sedimentary sequence is composed by a succession of sandy lacustrine clays (from basal levels to 4.4 m), organic lacustrine deposits such as gyttja (from 4.4 to 2.5 m) and peat (from 2.5 m to the current surface). Two radiocarbon dates (14C) indicate a deposition of sediments since the end of the Late Glacial period. Plant macrofossil remains, small charcoal particles (<2 mm), magnetic susceptibility peaks and archaeological remains from the near surroundings (handmade granitic-tempered ware and shards of flint) suggest a first human impact during the Early Neolithic period, close to 4,900 cal. B.C. The outcome of this high resolution study will allow clarification and absolute dating of this early anthropogenic impact (and of later pastoral and agricultural activities), which in turn will be compared to the palaeoecological analyses of other regionally important sites (e.g. nearby Pialeloup raised bog) in order to complete our vision of environmental changes during prehistorical and historical times.

    Résumé : In the last decade, the use of LIDAR data in archaeology has been widespread, providing unexpected results especially in the forested areas. Images obtained by the processing of LIDAR data show the overlay of archaeological structures fossilized in the territory, highlighting the diachronic origin of cultural landscapes. In this context, archaeomorphological approaches can provide theoretical and methodological tools for a diachronic “reading” of human-made landscape forms, and these can be useful for understanding the landscape genesis and its evolution as a social and cultural product. A LIDAR flight undertaken in 2011 in the Chaîne des Puys revealed agro-pastoral structures that had gone unnoticed under the forest protection area of Parc Régional des Volcans d’Auvergne. These facts gave rise to the LIDARCHEO research project (2012-2013), directed by F. Vautier and E. Roussel (Maison des Sciences de l’Homme de Clermont-Ferrand, France), and funded by Clermont Communauté. The project has combined the research of geomorphologists, geographers, archaeologists, historians and specialists in image processing with the aim of developing tools for automatic detection of archaeological structures from LIDAR data. The project allowed us to conduct the first archaeological study of agro-pastoral structures concentrated to the west of the Puy de Dôme. Moreover, it provided further data on buildings in the western sector of the Col de Ceyssat Roman site. Archaeomorphological study has been developed in a GIS database environment including; LIDAR digital terrain models (MDT), local relief models by LIDAR data (LRM), topographical and hydrographical vectorial information, old maps and old cadastral maps. It has also included archaeological surveys, micro-topographic measuring using a total station, archival and documentary research. Archaeomorphological analysis has allowed us to establish different types of agro-pastoral structures that have then been verified by archaeological surveys. Different chronological phases have also been identified between archaeological structures. Finally, morphotypological analysis has been used to develop automatic detection algorithms. This work hitghlights the contribution of archaeomorphological analysis into the study and diachronic interpretation of a mid-mountaincultural landscape from LIDAR data. Furthermore, it illustrates the role of the Archaeomorphology in the development and calibration of tools for automatic detection of archaeological structures from LIDAR data. Thus, Archaeomorphology is a discipline that can offer a wide range of methods and techniques for the study of cultural landscape configuration, as aiding the comprehension and interpretation of associated historical processes.

    Résumé : The Central Range of the Iberian Peninsula, arranged SW-NE, constitutes the boundary between the Duero and Tagus basins. It holds the highest altitudes (>2500 m a.s.l.) at its middle-west: the Gredos mountains, a strong siliceous massive of this submediterranean range. The current absence of natural forests at the highlands of Gredos (Central Iberian Range) has inspired controversial interpretations and remains today as a genuine feature of these mountains. In contrast, the available data about the vegetation history of the region indicates the existence of woodlands throughout the mid and late Holocene. Pollen records suggest that pinewoods have dominated during the mid- to late- Holocene, whereas the abundant macro- and mega-fossils studies support a prominent role of pines (mainly Pinus syvelstris) and birch at high altitudes (above 1300 m a.s.l.), especially during the late Holocene. Historical archives document the demise of forests since the Middle Ages and the intensification in the use of the pastures of the highlands of Gredos since the fourteenth century. No signs of proto-historic human presence have been still reported at the highlands but its influence has been well documented at lower altitudes, North and South of the Range. In this context we made the first pedoanthracological sampling in the region, in order to obtain information about the vegetation history at high altitudes, including treeline location in the past and the role played by shrublands. Five soil profiles across an altitudinal transect from 1800 m.a.s.l. to 2200 m.a.s.l. were sampled at the north slope of the Central Massif of Gredos, at the heart of Gredos range. Dated macrofossils (charcoals) indicate the occurrence of fire events since the early-Holocene (ca 9700 cal yr BP) until the recent-Holocene (ca 1000 cal yr BP), with several intermediate dates (ca 9000, ca 8400, ca 3700 and ca 2100 cal yr BP). The charcoal assemblages show a strong dominance of Leguminosae shrubs throughout the whole Holocene, accompanied by Betula sp. and Maloideae. This suggests the long-term occurrence of shrublands, probably similar in taxomonic composition to those occurring today, not detected before presumably because of their limited pollen production. We interpret the local presence of birch as scattered invidious or as belonging to small patches of forest among the dominant Leguminosae shrublands. On the light of these preliminary results, the Holocene treeline could be marked by Betula sp around 2000 m.a.s.l., as had been pointed by pollen studies in the westernmost part of the Central Range. Deciduous Quercus has been detected in the lower charcoal pit at 1800 m.a.s.l. which is coherent with current ecological data that report the occasional presence of this taxon at these altitudes in other areas of the range.

    Résumé : Since the last few years, archaeologists have the opportunity to use a very powerful tool in order to detect archaeological structures located in forest terrain : the airborne LiDAR. A Laser beam, emitted from an airplane, partially goes through the vegetation and is reflected on the ground. A measure of the time necessary for the light signal to return to the source allows then, knowing precisely the position of the transmitter, to reconstruct the relief very accurately. The cost of this tool tends to decrease, and it is now used in almost all the research programs dealing with archaeology when at least a part of the studied area is located under the vegetation. Resorting to the LiDAR yields a huge quantity of data, constituted of clouds made of millions of points from which it is necessary to extract the relevant information. A manual processing of these data is then boring, time consuming, and even sometimes impossible: the automation of the detection process becomes necessary. The presented work deals with the process of automatic detection of archaeological structures. It is applied to former agricultural constructions, built from the medieval to the modern period. They can be found in very high densities in some places in Auvergne. These structures have been chosen to test the process of automatic detection because they are particularly delicate to treat: they are indeed very variable in forms, appearing sometimes isolated, sometimes in group and they are characterised by small relief variations very difficult to detect among the global relief. The process presented uses the associated potentiality of Scilab and a Geographic Information System software. At first, the point cloud is interpolated in order to obtain a Digital Terrain Model (DTM). This DTM is then smoothed, by a moving average filter, in order to erase the abrupt relief variations, generally from anthropogenic origin: the macro relief is then highlighted. It’s then removed from the initial data, so that only the micro relief becomes visible. We thus obtain a Local Relief Model (LRM) in 2D ½.. An algorithm of automatic recognition allows then to detect the structures, to classify them, to extract their geometrical characteristics and to create a database in a totally automated way.

(BAR international series).
    Résumé : The study of the charcoal producing forest of the upper Dordogne valley is associated with a collective research project called "geohistory and geoarchaeology of the Limousin foresters' land" led by Geolab. The upper Dordogne valley is a unique massif of 1000 square kilometres of sloping forests located in the French regions of Auvergne and Limousin. This wide natural area offers a very interesting environment in which to exercise a biogeographical approach, but it has a little-known historical context. Indeed, this forest was exploited during both modern and contemporaneous times for its charcoal which was transported via the Dordogne River to the Bordeaux economical basin. Everywhere in these sloping forests, the vestiges of this activity are present. There are thousands of charcoal burning sites form the archaeobotanical corpus. This paper focuses on the charcoal analysis of 11 charcoal burning sites. The first anthracological results indicate a change in the arboreal composition of the forested landscape during the past three or four centuries. In this case, anthracology allows us to piece together the history of the tree diversity, which was influenced by charcoal burning.

    Résumé : Le département du Cantal, situé au cœur du Massif central, est notamment réputé pour ses burons, structures en pierre autrefois destinées à la production fromagère. Ayant pour la plupart perdu leur fonction première, ces centaines de bâtiments confèrent aujourd'hui encore un aspect bien particulier aux paysages des plateaux d'estive. Ils marquent le point d'aboutissement de diverses transformations architecturales, liées aux changements des modes d'occupation de la moyenne montagne. L'histoire de ces mutations a été peu abordée. Depuis 2000, elle est le thème de recherches d'une équipe d'archéologues, archivistes et paléoenvironnementalistes. La zone d'études retenue est un grand plateau de 60 km², dont l'altitude va de 1000 à 1600 m. Les recherches ont permis de mettre au jour, en-dessous de 1300 m, des hameaux et des fermes isolées, liés à une exploitation agro-pastorale des terroirs et datés des XI-XIIIè siècles. La vocation du territoire connaît ensuite une importante mutation, avec la mise en place d'une économie spécialisée d'élevage bovin saisonnier et de fabrication de fromage. Ce changement entraîne une transformation profonde des paysages, l'abandon des habitats antérieurs et la construction, à partir du XIVe siècle, de structures d'estive, à l'origine très rudimentaires, puis de plus en plus élaborées. Le XVIIe siècle voit l'apparition des premiers burons voûtés qui s'imposent totalement à partir du XIXe siècle.

    Résumé : En Europe occidentale et centrale, l’Holocène a connu plusieurs périodes d’instabilités de versant chroniques liées aux conditions climatiques. Le Tardiglaciaire et la transition avec le Boréal sont des périodes d’instabilités importantes liées à la fonte du pergélisol et à la décompression glaciaire dans les milieux alpins. Depuis une quinzaine d’année, le Subboréal est également reconnu pour connaître un regain d’activité gravitaire. Les glissements de terrain étant sensibles aux conditions d’humidité et d’imbibition du sol (entre autre), la présence de forte densité temporelle d’instabilités peut être le signe de période à bilan hydrique excédentaire.Le bassin versant de la Laussonne et ses périphéries (sud-est du bassin du Puy-en-Velay) présente d’importantes densités de paléoglissements de terrain jalonnant les escarpements basaltiques. Quatre paléoglissements ont été investigués par des approches combinées (géologie, géomorphologie et géophysique), datés par C14 AMS et un glissement a fait l’objet d’une étude palynologique.Les dates obtenues placent 3 glissements dans le Subboréal, période localement corrélée à un rafraîchissement du climat dans un contexte restant humide (maximum d’extension d’Abies et Fagus). Cette configuration climatique est cohérente avec un bilan hydrique excédentaire favorable à l’initiation ou à la réactivation de glissements d’ampleur. Cependant, de par sa position géographique aux confins des domaines climatiques atlantiques et méditerranéens et de par la forte influence montagnarde liée à l’altitude, l’hypothèse d’une majoration des épisodes cévenols lors de cette période reste ouverte.Finalement, la présence de ce cluster temporel de glissement au Subboréal semble bien être un marqueur des changements de conditions environnementales liés à la modification du bilan hydrique régional.

L’analyse montre que les 21 bois datés sont en châtaignier et proviennent d’arbres abattus durant l’hiver 1569. Ce lot de bois constitue une source d’information unique sur la gestion de la châtaigneraie limousine pour une période très peu documentée par les écrits, et l’exploitation de ces archives-cernes dans une perspective archéo-environnementale est envisagée. En 2008, ce projet est intégré à un PCR piloté par le Géolab, qui comprend déjà un volet sur l’histoire contemporaine de la châtaigneraie limousine (PCR « Géohistoire et géoarchéologie des territoires forestiers limousins »). La croissance des bois de la grange est comparée à celle de châtaigniers actuels représentant les trois types de peuplements existant aujourd’hui en Limousin : le taillis, la futaie et le verger. L’objectif est de définir dans quel type de peuplement arboré ces bois ont été prélevés. Les résultats indiquent que les bois de la grange seraient issus d’arbres de franc-pied, ayant poussé en ambiance forestière et prélevés sur une aire assez étendue. Le potentiel archéo-environnemental des bois anciens échantillonnés pour la datation du bâti est également discuté.

    Résumé : Geotourism and geoconservation are the main management issues of geoheritage inventories. In France, the INPG (National Inventory of Geological Heritage) constitutes a good basis for the definition of future protected areas and the further promotion of geoheritage. However, methodological adjustments are often necessary to fit with the different finalities of the inventory. The aim of this paper is to propose a cross-cutting approach of geotourism and geoconservation issues in the “Causses-du-Quercy” Regional Natural Park (PNRCQ), a rural territory typified by a rich geoheritage with a predominance of palaeontological and karstic sites. This geoheritage is currently the subject of protection measures (creation of a National Nature Reserve of geological interest, RNNg) and promotion actions (project of Geopark application). Because numerous geosites of the Regional Park are not managed, the PNRCQ aims to develop a substantive, integrated geoheritage project well beyond the limits of the reserve and extended to the whole PNR territory. To achieve this, two parallel studies (geoconservation and geotourism) were launched in 2013-2014. On one hand, a qualitative approach with cyndinic assessment – inspired by experience in risk evaluation – was proposed for the definition of a geoconservation strategy applied to karstic sites. On the other hand, a semi-quantitative method of geosite assessment – based on multi-criteria analysis adapted to geotourism purposes – met the need to define a ranking or priority-based classification of geosites of geotouristic interest, in accordance with the Regional Park management policy and the geoconservation issues. As a whole, this integrated work constitutes a solid, prospective basis for consolidating the project of Geopark application.

    Résumé : Le programme de recherches sur le peuplement de la planèze sud du Plomb du Cantal a débuté en 2000. Il concerne un secteur de moyenne montagne volcanique d'environ 50 km2, situé sur la partie haute des communes de Lacapelle-Barrès, Brezons, Malbo, Saint-Clément et Pailherols (cantons de Vic-sur-Cère et de Pierrefort, département du Cantal). L'altitude s'échelonne de 1000 à 1600 m. Le projet vise à reconstituer l'histoire du peuplement et des activités humaines des origines jusqu'à la fin de l'époque moderne. À cette fin, une équipe pluridisciplinaire et diachronique a été constituée, composée de paléoenvironnementalistes et d'archéologues. Les recherchent comportent des prospections pédestres et aériennes, des sondages, des fouilles programmées, l'étude des sources écrites et un gros volet d'études paléoenvironnementales. À ce jour, plus de 700 sites et indices de sites probables ont été recensés, depuis la pièce lithique préhistorique isolée jusqu'au hameau d'époque médiévale. L'ensemble constitue un corpus qui a pu être analysé à l'aide d'un Système d'Information Géographique. La chronologie des sites va de la Préhistoire récente, notamment de la transition Mésolithique final/Néolithique ancien aux époques médiévale et moderne caractérisées par de nombreux vestiges de bâtiments semi-enterrés. Abstract. A research project on the settlement of the southern "planèze" in Plomb du Cantal was launched in 2000. This project focuses on a medium-altitude volcanic mountain région approximately 40 km2 in area, which comprises the upper part of townships of Lacapelle-Barrès, Brezons, Malbo Saint Clément and Pailherols (in the cantons of Vic-sur-Cère and Pierrefort, department of Cantal). The altitude of the region studied ranges between 1000 and 1600 m. The aim of this project is to trace the history of human settlement and the human activities carried out in this region from the origins to the end of the modern era. For this purpose, a multidisciplinary research group was set up, consisting of both paleoenvironmentalists and archaeologists, to carry out the prospections on the field and from the air, coring explorations, excavations, archive searches and paleoenvironmental studies. In the first stage, the emphasis was on site detection, followed by coring explorations, systematic excavations and studies on written documents, and many paleoenvironmental studies were also carried out. More than 700 sites and candidate sites have been listed to date, from isolated lithic prehistoric sites to medieval hamlets. All the information collected forms a corpus, which was analysed using a Geographic Information System. The chronology of the sites goes from recent Prehistory, especially during the period of transition from the late Mesolithic to the early Neolithic period to Middle Age and Modern Times, which are characterized by many vestiges of half-buried buildings.

    Résumé : Clause Learning is one of the more important components of conflict driven clause learning (CDCL) SAT solver that is effective on industrial instances. Since the number of learned clauses is proved to be exponential in the worse case, it is necessarily to identify the most relevant clauses to maintain and delete the irrelevant ones. As reported in the literature , several learned clauses deletion strategies have been proposed. However the diversity in both the number of clauses to be removed at each step of reduction and the results obtained with each strategy creates confusion to determine which criterion is better. Thus, the problem to select which learned clauses are to be removed during the search step remains very challenging. In this paper, we propose a novel approach to identify the most relevant learned clauses without favoring or excluding any of the proposed measures, but by adopting the notion of dominance relationship among those measures. Our approach bypasses the problem of the diversity of results and reaches to a compromise between the assessments of these measures. Furthermore , the proposed approach also avoids another non-trivial problem which is the amount of clauses to be deleted at each reduction of the learned clause database.
