EEC is now: Experimental Evolution of Communities

Our group uses theoretical and experimental approaches to understand the ecological and evolutionary dynamics of species interactions and disease.

Our main experimental systems are Pseudomonas aeruginosa and its lytic phages and the protozoan Paramecium caudatum and its bacterial parasite Holospora undulata).

Disentangling the role of connectivity, environmental filtering, and spatial structure on metacommunity dynamics

Vincent Devictor, Nicolas Mouquet and collaborators have published a paper in Oikos where Ocean models are used to evaluation the exchange rates of organisms between communities in a marine Mediterranean coastal area; These were used to quantify the effects of realistic connectivity on local and regional polychaete community structure, and revealed that the environmental gradient, geographic distances. This [...]

Evaluating evolutionary models of stress-induced mutagenesis in bacteria

Clara Torres-Barceló published a review paper in Nature Reviews Genetics on hypothesis aiming to explain the evolutionary importance of stress-induced mutagenesis in bacteria.

MacLean RC, Torres-Barceló C., Moxon R.E. (2013). Evaluating evolutionary models of stress-induced mutagenesis in bacteria. Nature Reviews Genetics 14, 221-227.

Increased mutation rates under stress allow bacterial populations to adapt rapidly to stressors, including antibiotics. Here we evaluate [...]

Russian invasion, part 2

EEC is currently hosting Alexey Potekhin and Irina Nekrasova, for a collaboration with Oliver Kaltz.

Alexey and Irina are professors at the Dept. of Microbiology, Faculty of Biology and Soil Science of St Petersburg State University. Their research focuses on ciliate Paramecium as a model to study species divergence and mechanisms of speciation. Paramecium has opposite [...]
