Antonio Baeza is an evolutionary and behavioral ecologist. He believes in the marriage between hypothesis-driven studies and natural history to improve our understanding of natural phenomena in the marine environment. Baeza’s research goals focus on testing sex allocation and mating systems theories using marine invertebrates (mostly crustaceans) as model systems. He is also interested in understanding the role of the environment in determining the evolution of social behaviors and other behavioral traits (i.e., alternative mating tactics, territoriality, and symbiosis). Currently, he is a postdoctoral fellow at the Smithsonian Tropical Research Institute, Panama, and at the Smithsonian Marine Station, Fort Pierce, Florida, USA. He has published 26 original papers (plus two book chapters) on the behavioral ecology and life history of crustaceans. He has experience in presenting his research to the public as he has been invited before to various symposia at international meetings and seminars at different universities.
