Abstract Investigation of Lake Allos sediments revealed ~ 160 graded layers, interpreted as flood deposits, over the last 1400 yr. Comparisons with records historic floods support interpretation deposits and suggest that most recorded events are result intense meso-scale precipitation events. As there is no evidence for any major changes in erosion processes catchment since Medieval Warm Period (MWP), we interpret record terms repeated millennium, a low frequency during MWP more frequent...
Abstract Over the last decade, an increasing number of studies have used lake sediment DNA to trace past landscape changes, agricultural activities or human presence. However, processes responsible for formation and properties might affect records via taphonomic analytical processes. It is crucial understand these ensure reliable interpretations “palaeo” studies. Here, we combined plant mammal metabarcoding analyses with sedimentological geochemical from three lake-catchment systems that are...
Abstract Pollen and plant macrofossil records from a selection of sites in Spain, France Italy are used to explore the origin development Mediterranean vegetation. The role evergreen summergreen taxa is discussed. expansion sclerophyllous trees during Pleistocene interglacials well correlated with orbital forcing. During Holocene, large number data illustrates latitudinal longitudinal differences vegetation dynamics. Multidisciplinary studies identify short terms climatic fluctuations....
A 144-cm-long core was obtained in Lake Petit (2200 m a.s.l., Mediterranean French Alps) order to reconstruct past interactions between humans, the environment and climate over last five millennia using a multidisciplinary approach involving sedimentological, geochemical botanical analyses. We show complex pattern of environmental transformation. From 4800 4200 cal. BP, podzol-type soils progressively developed under forest cover. This stable situation interrupted by major detrital pulse at...
Abstract Understanding the role of climate and humans in generating mountain slope instability is crucial because such influences downstream fluvial activity a major threat to societies. Here, we use sedimentary archive Lake Allos (southeastern France), lake European Alps, characterize flood deposits vegetation dynamics over past 7000 yr. Our results support interpretation critical threshold catchment sensitivity erosion at 1700 calibrated (cal.) yr B.P. (A.D. 250) probably resulting from...
Abstract. In the Mediterranean area, 4.2 ka BP event is recorded with contrasting expressions between regions. southern Alps, high-altitude Lake Petit (Mercantour Massif, France; 2200 m a.s.l.) offers pollen and diatom-rich sediments covering last 4800 years. A multi-proxy analysis recently revealed a detrital pulse around 4200 cal due to increasing erosion in lake catchment. The involvement of rapid climate change leading runoff soil was proposed. Here, order clarify this hypothesis, we...
In the context of global pollinator decline, little is known about protection status and ecology many species. This lack knowledge particularly important for Mediterranean protected areas that harbor diverse communities are subject to considerable anthropogenic pressures. Calanques National Park (85 km2), which located near Marseille (France), dominated by low-vegetation habitats, such as phrygana scrublands. These habitats offer favorable conditions species due amount floral resources....
A 1.70 m core extracted from the Lac des Lauzons, Haut Champsaur, French Alps, at 2180 altitude, provided a detailed Holocene record of beetles, pollen and plant macrofossils, enabling reconstruction local palaeoenvironmental changes during last 10 000 years. After an early phase colonization by plants insects, corresponding to Lateglacial interstadial, long relative stability ecosystems (at least in vicinity lake) is recorded. Strikingly, there no evidence beetle macrofossils that treeline...
Recent climate and land use change, pollution have led to concerning alterations in biodiversity ecosystem functions, jeopardizing nature's contributions people. Mountainous regions are not immune these threats, experiencing the impacts of global warming, increased recreational activities, changes agricultural practices. Leveraging natural elevational gradients mountain environments, ORCHAMP program was established 2016 as a comprehensive initiative monitor, understand, predict repercussions...
