Full textThe postglacial vegetation history in the south of Massif Central (France) was reconstructed using a multidisciplinary palaecological approach with (pollen and geochemical analyses). The main objectives were to evaluate the impact of past human activities on the long-term vegetation dynamics and to retrace the land uses for two sectors: the Cévennes National Parc and the Regional Parc of Haut Languedoc. The study of several peatlands delivered a vegetation history since the Atlantic period. In the two studied sectors, human activities were identified since the Neolithic period and were mainly attributed to pastoral activities, whereas agriculture was very limited. Then, agro-pastoral activities and deforestation became more important, reaching a peak at the end of the Roman period at the Mont Lozère and at the beginning of the Middle Ages for two sectors. The deforestations during the Iron Age at Mont Lozère have principally affected beech while in the Regional Parc of Haut Languedoc beech seems not to be affected during this period. At Mont Lozère, metallurgical lead activities were attested by several archaeological proofs. Multidisciplinary approach (pollen and geochemical analyses) of the Narses Mortes peatland shows two periods of metallurgical activities: the known Medieval one and a second older period: the Gabales metallurgy (Iron Age), which has not been already identified by archaeology and this is the first evidence for this metallurgy activities. Deforestation linked to metallurgical activities principally affected the beech

Full textHydrological and sedimentological investigations were carried out on a vegetated secondary channel of the Loire River (Bréhémont, France). Sediment dynamics is important in the upstream part of the channel while an asymmetrical behaviour is noted in the downstream part : sediment by-passing in the bare areas contrasts with particle retention in the vegetated parts. Locally, flow velocities, directions and sediment deposition are influenced by vegetation. Models of evolution are discussed. During moderate floods, reduced redistributions indicate poor sedimentary supply from the mean channel. During intense floods (1) high quantities of sediments delivered by the mean channel allows the feeding of riffles and bars, (2) vegetation bands influence flow velocities and directions. Deposition and retention of sediment are induced by these bands while erosion is important in their periphery. Accretion in the vegetated areas exerts a feedback control on flow and sediment transport

Full textThe landscapes of the French island of Corsica are the result of the grazing tradition which has always occupied a pivotal position in the island's economy. Furthermore, in the last fifty years, a reduction in the pressure from human activity has lead to changes in plant cover. This article intends to study the evolution of dynamic mechanisms during the secondary successions and the effect of changes in vegetation on plant diversity. Our study was based on a simultaneous study of 375 plots carried out between May and September from 1996 to 1998. We studied the floristic composition of each stage both qualitatively (life form, adaptive strategy and seed disperal mode) and quantitatively (species richness, equitability, Shannon index). The results show a change in species and environmental conditions, with a progressive move from heliophilic grassland and low shrub species with an S or SR strategy, anemochoric and with a high tolerance for soil quality to a final stage of dense forest composed of competitive (C or CS) zoochoric or barochoric phanerophytes. Moreover, the turning point in Corsica in terms of floristic diversity lies between 20 and 55 years after land abandonment. Successions are due to a series of rapid interactions. Thus, when a site is given reserve or protected area status, we need to take into account the fact that it will evolve according to the biological traits of the species. From a research point of view, we need to look at process diversity and the role of each of the species present during the successions

Full textThe conservation of the biodiversity is now recognized like a priority measure to implement. However the factors responsible for its evolution are much less known. In this context, we study the factors responsible for the dynamics of the plant biodiversity, in the intensive farming landscapes of the "Lauragais haut-garonnais" (South-Western France), within a contemporary temporal framework. We carried out a multi-sites and multi-dates analysis which offer to understand the space organization of the components of the landscape mosaic, to propose bases for conservatory management. The study reveals a global reduction of the plant biodiversity, mainly under the influence of the degradation of the habitats (decrease and fragmentation) and the modern practices. However, prospects for conservatory management are still possible in these strongly anthropized landscapes
