Cette thèse a pour objectif de fournir des reconstitutions à haute résolution des changements hydroclimatiques et de la végétation ayant affecté le bassin amazonien au cours des 200 000 dernières années. Pour ce faire, elle utilise des biomarqueurs moléculaires et leurs compositions isotopiques ...
Over the last century, the High Arctic has experienced rapid warming, with the Arctic warming four times as fast the global average since 1979. This has resulted in major impacts to Arctic ecosystems. Lakes are especially sensitive sentinels of such environmental change, responding to climate ...
You will be part of a Marie Curie Doctoral Network project, PacificPeopleForest, entitled History, Archaeology, and Botany of Pacific Islands: assessing the Long-Term Impacts of Early European colonialism on Peoples and Forests. Current definitions of native forests for the Mariana Islands tend ...
Since the onset of agriculture and animal husbandry around 10,000 years ago, biodiversity has undergone profound transformations. Palaeoenvironmental records reveal that land clearance, grazing and cultivation replaced diverse natural habitats with anthropogenic landscapes, leading to declines in ...

The candidate will assess, integrate and evaluate the available data fit to quantify human impact on vegetation and landscape change based on environmental proxies on a long-term perspective throughout the Holocene period in a number of selected, well-researched micro-regions with suitable ...
You will be part of a Marie Curie Doctoral Network project entitled History, Archaeology, and Botany of Pacific Islands: assessing the Long-Term Impacts of Early European colonialism on Peoples and Forests (short name, PacificPeopleForest). Currently, knowledge on the ‘native’ forest in the ...
Les agroécosystèmes jouent un rôle économique essentiel, mais ils exercent également une forte pression sur l’environnement, en contribuant à la pollution, à la perte de biodiversité, aux émissions de gaz à effet de serre, au réchauffement climatique et aux risques pour la santé humaine. L’un des ...
