Evolutionary Ecology
of Fishes Laboratory
|
Updated: September 4,, 2024
We are interested in evolutionary ecology, in other words, why organisms do the things that they do. Most of our work focuses on fish reproduction and parental care, though we are interested in all aspects of evolutionary ecology. The lab logo illustrates Tomocichla tuba, a fascinating cichlid fish found in eastern Costa Rica, which I have studied for many years at the La Selva Biological Station and elsewhere in Costa Rica.
