Phase polyphenism has been hypothesized as an evolutionary response to cannibalism avoidance. Group movement was also proposed as an adaptation to predation risk. Alternatively, we propose that phase polyphenism could emerge as a response to variable conditions of resource, mainly vegetation. The

SOLAB’s general objective is to improve our ability to anticipate and manage coastal ocean evolutions. Its key premise is that adaptation, mitigation, restoration, and hazard prevention strategies have to be based on an in-depth integrated understanding of the present and past system states and thei

1) Explore the diversity of propagation waves in relation with the ecological characteristics of populations We will investigate with complementary modelling approaches what are the ecological mechanisms that may induce pushed propagation waves, with a focus on mechanisms associated with frequent c

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

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

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

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

The vast majority - around 70 to 80% - of the plant organic matter produced on earth will ultimately end in the form of detritus in nature (dead leaves, dead wood, root exudates, etc.). The decomposition of these detritus constitutes, along with primary production (i.e. the production of biomass by

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
