About this position
This postdoctoral position at CNRS is part of the ECO-EVO BIODIV project, which develops an integrative eco-evolutionary approach to understanding biodiversity and its dynamics. The project brings together concepts and methods spanning biodiversity levels, biological groups, intra- and interspecific variation, and the spatial and temporal processes that shape them.
The advertised research focuses on building and analysing theoretical models of simple trophic modules, such as a predator, two prey species, and a resource, in a spatial context. The aim is to study how intraspecific and interspecific interactions combine to structure coexistence through ecological and evolutionary processes, especially competition and predation. A particular emphasis is placed on the links between evolutionary dynamics and trophic assembly, with relevance to biological invasions.
The work will also connect theory with a long-term freshwater case study from Martinique within ECO-EVO BIODIV. The system involves a predatory crayfish and two snail species competing for a biofilm resource. The two snail species are clonally reproducing and ecologically and phylogenetically close, while the crayfish shows marked sexual dimorphism that affects predation. This invaded freshwater system offers a concrete setting for exploring how eco-evolutionary dynamics shape abundances, traits, invasion dynamics, niche displacement, and spatial effects across trophic levels.
The project is strongly theory-driven and relies on analytical modelling and simulation approaches, building on existing work developed by the host teams. The postdoctoral researcher will progressively develop eco-evolutionary models of increasing complexity to address the mechanisms underlying invasion, coexistence, and trait evolution in trophic chain modules.
