The loss of biodiversity caused by global changes is a major concern from political, scientific and societal perspectives. In particular, Western Europe has been heavily affected by disturbances such as urbanisation, agricultural intensification and climate changes. The speed and intensity of these recent changes call for developing integrative approaches to measure, understand, and predict the responses of biodiversity under different scenarios of climate change and human activities.
My Ph.D. project aims at better understanding the impact of global changes (the combination of climate change and human activities) on biodiversity, and focuses more specifically on the mechanisms of response and adaptation induced by global change on birds. I generally use large-scale and long term biodiversity survey data coupled with climatic and land-use datasets to develop specific research on the mechanisms of species and community responses aspects of biodiversity.
I specifically address the following issues :
– What is the temporal and spatial responsiveness of community reshuffling induced by climate variations ?
– How climate-induced changes in community composition affect ecological and functional characteristics of these communities ?
– Can protected areas mitigate climate change impacts on species and communities?
– How and why are community dynamics affected by the joint effects of global warming and land use change ?
– Why are some species more likely to be affected or adapt to each of these large-scale environmental changes ?
