The Mediterrranean Basin is considered one of the world hotspot for biodiversity as well as the most critical regions regarding the impacts of climate change, prolonged-droughts being one of the main concerns.
We will evaluate at a regional scale the impact of rainfall changes :
1) directly by measuring litter production and decomposition of Mediterranean Oak forest;
2) indirectly by measuring litter decomposition through changes in litter biochemical composition, particularly the quantity and diversity of plant secondary metabolites and
3) the possible effects on plant community and soil diversity dynamics.
LPJ-GUESS model will be used in order to simulate ecosystem patterns and processes (carbon allocation due to secondary metabolites production and soil biodiversity interactions under climate changes projections). The results of the model simulations will be available to forest managers and skateholders in order to lead to concrete actions for the adaptation to climate change and biodiversity conservation of the oak forest in the Provence Region.
