Marty Crump is a behavioral ecologist who works with tropical amphibians in the areas of parental care, reproduction, territoriality, cannibalism, and tadpole ecology. She has published several books on her research and experiences in tropical areas such as Costa Rica, Brazil, Chile, and Argentina. One of these books, In Search of the Golden Frog (University of Chicago Press, 2000) chronicles her unique experiences in Costa Rica's Monteverde Cloudforest, where she collected data on the now extinct Golden Toad highlighted in this module. She acted as a mentor to the authors of this module, since her research is invaluable when profiling the Golden Toad species. Marty received her Doctorate degree from the University of Kansas in 1974 and is currently an adjunct professor at Northern Arizona University.
