Experimental Evolution of Communities

Our group uses theoretical and experimental approaches to understand the ecological and evolutionary dynamics of species interactions and disease. We integrate eco-evolutionary processes in dynamical landscapes, which incorporates issues such as spatio-temporal variation in environmental conditions, disturbance and connectivity (dispersal). We also study cancer evolution, the evolution of social strategies and innovations.

Our main experimental systems are protozoan model species (Tetrahymena, Paramecium) and their natural enemies (Didinium, Holospora), as well as bacteria (Pseudomonas aeruginosa) and their lytic phages.

EEC is looking for master students

Master projects are available in our group! Possible projects focus on eco-evolutionary dynamics in fragmented landscapes. Using both theoretical and/or experimental evolution approaches, the aim of the projects is to investigate the joint effects of environmental forcing (disturbance) and biotic forcing (parasites, predators, competitors) on demographic dynamics and epidemiology in structured populations, and the consequences […]

Phages and bacterial social evolution

A new article published by Marie Vasse, Clara Torres-Barceló and Michael Hochberg in the Proceedings of the Royal Society of London B, shows how phage predators impact social dynamics in the pathogenic bacterium Pseudomonas aeruginosa.

While predators and parasites are known for their effects on bacterial population biology, their impact on the dynamics of bacterial social […]
