Researchers from UTA and UNAM appear on a local television program in the state of Coahuila to discuss their investigations of Mexican amphibians, reptiles, and parasites in August of 2007.
Herpetology of Mexico is a preliminary attempt to characterize the vast amphibian and reptile diversity of Mexico. The majority of information on this website has resulted from fieldwork conducted by an international team of researchers from the University of Texas at Arlington (UTA) and the Universidad Nacional Autonoma de México (UNAM). This research was made possible be generous grants from the National Science Foundation (DEB-0102383 and DEB-0613802 to J. A. Campbell).
Mexico is a country of particular biogeographical interest
because it includes the transition zone between the two
great faunal regions of the Western Hemisphere, the
Neartic and Neotropical. About 1100 described species
of amphibians and reptiles are known from Mexico, and
62% of these species are known only from Mexico.
Approximately one hundred new species of amphibians
and reptiles have been described from Mexico since
1980 even without an organized survey for the country.
It is anticipated that 200+ species of amphibians and
reptiles, and a far larger number of parasites, remain to
be discovered in Mexico. The UTA/UNAM investigations
conducted between 2001 and 2010 have resulted in
large natural history collections of amphibians, reptiles,
and their parasites. Thus far these collections have allowed
for a better understanding of species distributions and most importantly have led to the discovery of several new species.
The urgency for describing Mexican biodiversity is more acute than for other tropical countries, for several reasons. First, human population density in Mexico has now reached the point where the last vestiges of forests are disappearing in many areas, and these forests are recognized for their extremely high biodiversity and levels of endemism. Second, the diversity of amphibians and reptiles in Mexico is higher than any other country in the world, regardless of size or location. Finally, dramatic population declines have been identified in both amphibians and reptiles; some species have already been lost and others will follow soon.
