Coastal oceans and the services they provide are socially, economically and environmentally essential, particularly for the populations that inhabit their shores. These regions are subjected to major anthropogenic stress from local origin but also as a consequence of global changes: upper ocean warm

PAMPAS focuses on the future of the coastal marshes of Charente-Maritime and their management against the marine submersion hazard. This project chooses to tackle this issue through a focus on the heritage identity of those marshes to go beyond the classical approaches of conservation ecology, stand

Studies of plant defense against parasites have focused mainly on qualitative resistance controlled by major-effect genes, which is often compromised by the counter-adaptation of the targeted parasite. Such resistance breakdowns induce heavy economic losses and a waste of genetic resources. The Arch

In a context of ever-increasing demand for food, the future of farming requires to develop sustainable solutions to produce more food without causing major harmful effects on the environment. In particular, broad-range pesticides and chemical fertilisers need to be phased out in favour of naturally-

In the context of climate change and increased perturbations caused by human activities, understanding the evolvability and resilience of populations colonizing new areas is of critical importance. Although reproduction is the most influential trait governing evolutionary responses to environmental

The role of ponds in pesticide transfers in agricultural catchment remains largely unexplored, with also the majority of processes involved in pesticide dissipation still of unknown contribution. This results in sub-optimal operational use of ponds. Using field survey data, a cutting-edge hydro-biog

The nitrogen fertilizer used for crop production is partially emitted as N2O, a gas having about 300 times more impact on global warming than CO2. N2O is generated during microbial nitrification and denitrification, which are common in agrosystems. The whole denitrification process requires optima

In ecosystems, plants and microbial decomposers are generally considered as the two most important biological components of ecosystems, plants furnishing organic carbon and energy to all food webs components, and decomposers permitting to recycle, through their mineralization activity, dead organic

Locust species alternatively display harmless solitarious and gregarious phenotypes. The latter create migrating bands and swarms that are devastating for all types of agriculture. This plasticity, named phase polyphenism, has been hypothesized as an evolutionary response to cannibalism avoidance. G

In colonization processes, propagation waves may be « pulled » when a few individuals on the front drive expansion, or « pushed » when all individuals from the core are involved. Although these concepts directly relate to the ecological properties of populations in a novel environment, so far they h
