Department Fish Ecology and Evolution

Fish Ecology & Evolution (FishEc)

We study ecology, evolution and biodiversity of fishes and other aquatic organisms. We are interested in the mechanisms that drive the origins, the maintenance and the loss of species, genetic and functional diversity.

A nice journalistic article appeared in Nature this week that emphasizes the increasing realization among ecologists that evolution affects ecology at all scales of time and space. The story features the mesocosm experiments of our former Postdoc Rebecca Best with two kinds of stickleback and their hybrids. Rebecca published this work in Nature Ecology & Evolution last year.     

Jacco van Rijsel, Florian Moser, David Frei and Ole Seehausen published a new paper in Proceedings of the Royal Society B on the influence of disruptive selection on speciation with gene flow. They ask whether differences in present day divergent ecological selection can explain differences in extent of divergence between sympatric species.

Hari Sridhar revisits Ole's 1997 Science paper. Hari Sridhar, theoretical ecologist at the Indian Institute of Science, Bengaluru, interviews authors of well-known papers in ecology and evolution. The idea is to learn about the making of the paper, the impact the paper had on the author’s career and research and the author’s current stand on what was said in the paper.
