Dr. Marcio Martins got his degrees of Biologist (1984), MSc in Ecology (1990), and Ph.D. in Ecology (1994) at the State University of Campinas. He is a Full Professor (since 2006) at the Department of Ecology, Institute of Biosciences, University of São Paulo (USP) since 1996. Previously he was a researcher at the National Institute for Amazonian Research (INPA) and a visiting professor at the Federal University of Amazonas (UFAM). He has been a post-doc at the São Paulo State University, Rio Claro (1995-1996), and at the University of Florida, Gainesville (2013). His main research interests are to understand (1) the processes that lead to spatial and temporal patterns of diversity of amphibians and reptiles, and (2) the threats and vulnerabilities of amphibians and snakes. To achieve these goals, he invests heavily in the gathering of good natural history data. Marcio published about 90 research papers and a dozen book chapters on the biology and conservation of amphibians and snakes. He has been participating actively in the production of Brazilian red lists of threatened fauna (2003, 2014, and the ongoing process) and is the regional coordinator for South America of the IUCN Viper Specialist Group.
