The beech-fir forest, the baseline natural forest ecosystem in the montane belt of temperate Europe
A study of late Holocene local vegetation dynamics and responses to land use changes in an ancient charcoal making woodland in the central Pyrenees (Ariège, France), using pedoanthracology
Late Holocene history of woodland dynamics and wood use in an ancient mining area of the Pyrenees (Ariège, France)
Atmospheric and terrigenous metal accumulation over 3000 years in a French mountain catchment
A Late Antique Vegetation History of the Western Mediterranean in Context
Fossil pollen records from 70 sites with reliable chronologies and high-resolution data in the western Mediterranean, were synthesised to document Late Holocene vegetation and climate change. The key elements of vegetation dynamics and landscape construction during Late Antiquity are clear in the light of the fossil pollen records. These are: fire events (natural or anthropogenically induced); grazing activities in high-mountain areas; agricultur…

Social-ecological systems in the Anthropocene
Understanding social-ecological system dynamics is a major research priority for sustainable management of landscapes, ecosystems and resources. But the lack of multi-decadal records represents an important gap in information that hinders the development of the research agenda. Without improved information on the long-term and complex interactions between causal factors and responses, it will be difficult to answer key questions about trends, rat…

Climate and land-use change during the late Holocene at Lake Ledro (southern Alps, Italy)
This paper investigates the relative influences of climatic and anthropogenic factors in explaining environmental and societal changes in the southern Alps, Italy. We investigate a deep sediment core (LL081) from Lake Ledro (652 m a.s.l.). Environmental changes are reconstructed through multiproxy analysis, that is, pollen-based vegetation and climate reconstruction, magnetic susceptibility (MS), lake level, and flood frequency, and the paper foc…

North–south palaeohydrological contrasts in the central Mediterranean during the Holocene
On the basis of a multi-proxy approach and a strategy combining lacustrine and marine records along a north–south transect, data collected in the central Mediterranean within the framework of a collaborative project have led to reconstruction of high-resolution and well-dated palaeohydrological records and to assessment of their spatial and temporal coherency. Contrasting patterns of palaeohydrological changes have been evidenced in the central M…
Recent climatic and anthropogenic imprints on lacustrine systems in the Pyrenean Mountains inferred from minerogenic and organic clastic supply (Vicdessos valley, Pyrenees, France)
High-resolution seismic profiling has been combined with geochemical analyses of both watershed samples and five lacustrine cores retrieved from two natural lacustrine basins of glacial origin: Lake Majeur and Lake Sigriou (1630 m a.s.l. and 1995 m a.s.l., respectively, Eastern French Pyrenees). Identifying specific minerogenic and organic markers of autochthonous and allochthonous supply, data allow documenting past climatic and anthropogenic pr…

Holocene history of fire, vegetation and land use from the central Pyrenees (France)
Located on a mountain pass in the west-central Pyrenees, the Col d'Ech peat bog provides a Holocene fire and vegetation record based upon nine 14 C (AMS) dates. We aim to compare climate-driven versus human-driven fire regimes in terms of frequency, fire episodes distribution, and impact on vegetation. Our results show the mid-Holocene (8500–5500 cal yr BP) to be characterized by high fire frequency linked with drier and warmer conditions. Howeve…
Holocene palaeohydrological changes in the northern Mediterranean borderlands as reflected by the lake-level record of lake ledro, northeastern Italy
A lake-level record of Lake Ledro (northern Italy) spans the entire Holocene with a chronology derived from 51 radiocarbon dates. It is based on a specific sedimentological approach that combines data from five sediment profiles sampled in distinct locations in the littoral zone. On a millennial scale, the lake-level record shows two successive periods from 11,700 to 4500 cal yr BP and from 4500 cal yr BP to the present, characterized by lower an…
Caractérisation de la fermeture des paysages dans les Pyrénées depuis les années 1940. Application sur le Haut-Vicdessos
La reforestation des versants pyrénéens a été décrite sans être pour autant être quantifiée avec précision. Cette contribution vise à proposer une méthodologie utilisant les données de télédétection pour caractériser l’ampleur, la vitesse et les types de changements d’occupation et d’usages des sols dans une vallée ariégeoise. Les résultats témoignent d’une fermeture des versants dès la fin des années 1950, à partir des années 1960 pour les fonds…
Hurricanes and climate in the Caribbean during the past 3700 years BP
A multiproxy analysis of lacustrine sediments cored in Grand-Case Pond at Saint-Martin, north of the Lesser Antilles archipelago, reveals three distinct climatic periods for the last 3700 years. From 3700 to ~2500 yr cal. BP and from 1150 yr cal. BP to the present, carbonate mud deposition occurred in connection with pond lowstands. These periods were also punctuated by severe drought events, marked by gypsum laminae, and hurricane landfalls, lea…
Modern and fossil non-pollen palynomorphs from the Basque mountains (western Pyrenees, France)
Rhythms and causalities of the anthropisation dynamics in Europe between 8500 and 2500calBP
Multidisciplinary approach to reconstructing local pastoral activities
In this study archaeology, history and palaeoecology (modern and fossil data sets of pollen and non-pollen palynomorphs) were used to reconstruct small-scale pastoral activities in the Pyrenees Mountains during the last two millennia. Modern pollen assemblages from the major vegetation units (both natural and anthropogenic) are studied on one restricted watershed area. A correlative model (RDA) of 61 modern pollen spectra and 35 external variable…
Fire frequency and landscape management in the northwestern Pyrenean piedmont, France, since the early Neolithic (8000 cal. BP)
Both quantitative reconstruction of fire frequency from charcoal counts and pollen analysis were undertaken on a 312 cm sediment core from Gabarn peat bog. An 8000 yr cal. BP palaeofire record and vegetation history were established on the basis of nine 14 C (AMS) dates. As anthropogenic Inferred Fire Frequency (IFF) has seldom been studied, we test and discuss two different methods of frequency calculation. Our results shows a clear Holocene bip…
Modern and fossil non-pollen palynomorphs from the Basque mountains (western Pyrenees, France)
Modern pollen assemblages from grazedvegetation in the western Pyrenees, France
Modern pollen assemblages from grazed vegetation in the Pyrenees Mountains (France) were studied with the aim of providing a calibrated model for reconstructing past pastoral activities. The modem analogues were selected to cover the major gradients of grazing pressure and degree of openness. The vegetation was surveyed by means of the synusial integrated method, assessing the structure and the patchiness of the pastoral phytoceonoses. A correlat…

Late-Holocene climatic variability south of the Alps as recorded by lake-level fluctuations at Lake Ledro, Trentino, Italy
A lake-level record for the late Holocene at Lake Ledro (Trentino, northeastern Italy) is presented. It is based on the sediment and pollen analysis of a 1.75 m high stratigraphic section observed on the southern shore (site Ledro I) and a 3.2 m long sediment core taken from a littoral mire on the southeastern shore (site Ledro II). The chronology is derived from 15 radiocarbon dates and pollen stratigraphy. The late-Holocene composite record est…
A study of late Holocene local vegetation dynamics and responses to land use changes in an ancient charcoal making woodland in the central Pyrenees (Ariège, France), using pedoanthracology
Nouveaux milieux, nouveaux gibiers, nouveaux chasseurs ? Évolution des pratiques cynégétiques dans les Pyrénées du Tardiglaciaire au début du Postglaciaire
The climatic changes which occurred during the Late Glacial and at the beginning of the Post Glacial considerably modified the natural environment of prehistoric populations. For certain authors, these modifications were at the origin of a massive integration of small animals in the diet. In the French Pyrenees and on their borders, broadening diets occur at the end of the Older Dryas. Archaeozoological data coupled with palaeoenvironmental data …

Les apports de la palynologie à l'histoire rurale
En se positionnant désormais comme une discipline clairement anthropocentrée, la palynologie contribue à mieux appréhender les relations complexes entretenues entre les sociétés humaines et l'environnement et offre également une nouvelle lecture des dynamiques agraires. L'exemple pyrénéen est, à ce titre, révélateur. Plusieurs séquences polliniques provenant de recherches récentes permettent d'apprécier sur la longue durée les dynamiques rythmiqu…

Au pays maya des lacs et des marais. Recherches archéologiques et géographiques (1999-2001)
Les socits mayas des hautes terres ont connu un dclin culturel marqu la fin du Prcla ssique (vers 100-250 apr. J. C.) au moment o, pour la plupart, les cits mayas des basses terres prenaient leur essor au dbut du Classique (250-300 apr. J. C.). Environ 600 ans plus tard , celles du Petn (Guatemala) taient presque toutes abandonnes, tandis que celles des basses terres du nord (Mex ique) connaissaient leur apoge jusqu'au dbut du Postclassique.

La métallurgie du fer au Pays Basque durant l’Antiquité. État des connaissances dans la vallée de Baigorri (Pyrénées-Atlantiques)
Une étude de la métallurgie antique du fer a été engagée au Pays Basque, dans la vallée de Baigorri, un secteur dont les gisements métallifères ont été exploités dès avant l’Antiquité et parfois jusqu’au XXe siècle. Les prospections et les investigations entreprises ont révélé l’existence de deux districts miniers et métallurgiques dont la chronologie est comprise entre la fin de l’âge du Fer (IIe siècle a.C.) et le IVe siècle p.C. Les mines, les…
