Javier Manjarrez

PeerJ Editor, Author & Reviewer

Summary

He received a B.S. in Biology, M.Sc., and Ph.D. in Ecology from the
Universidad Nacional Autónoma de Mexico (UNAM). He is currently a Professor of Biological Sciences at the Universidad Autonoma del Estado de Mexico. Most of his research interests have centered on the behavioral ecology of snakes and evolutionary processes that shape ecological diversity in sympatric species. Although he prefers working with snakes, his research has involved a variety of animals ranging from hylid frogs to domestic birds and mammals. Javier teaches courses in ecology, animal ecology, and statistics.
