Research interests

I have a broad interest in ecology, evolution and conservation of biodiversity. Usually I use fish as biological models to test ecological and evolutionary theories. In the last years, I have worked with several different subjects, such competition, niche overlap, predation, autoecology (eg, reproduction and feeding), patterns in metacommunities distributions, assembly processes, body size distribution and efficiency of protected areas.
