William Szelistowski

My primary area of interest is the ecology of tropical and subtropical shallow-water environments and their fishes; much of my work is conducted on the Pacific coast of Costa Rica. Specific interests include ecology of mangrove and coral reef fishes, mangrove intertidal ecology, food web relationships, and fish population biology and evolution. My research regularly involves undergraduate students as assistants.


Principles of Ecology, Biology of Fishes, Elasmobranch (shark and ray) Biology & Management, Tropical Ecology in Costa Rica, and Introduction to Marine Science.
