Resumen: "The three Mexican states of the Yucata´n Peninsula have been relatively
well explored for herpetofauna, when compared with other states of the country.
However, most studies on the herpetofauna of the Yucata´n Peninsula have focused
on their diversity, taxonomy, and species distribution, and less on their ecology,
behavior or conservation status. The major conservation efforts have focused on sea
turtles. Although some conservation programs exist locally for crocodiles in the
north of the peninsula, to date conservation strategies have mostly been restricted to
the designation of protected areas. With 24 species of amphibians and 118 species
of reptiles, the Yucata´n Peninsula harbors 11.5 % of national herpetofauna diversity,
and 19 % of species are endemic to the peninsula. Reptiles and amphibians are
two major globally threatened groups of vertebrates, with amphibians being the
most threatened vertebrate class. Both groups face the same threats, namely habitat
loss and modification, pollution, overharvest for food and pet trade, introduction of
exotic species, infectious diseases, and climatic change. Unfortunately, almost none
of these issues have been investigated for key populations in the Yucata´n Peninsula.
For amphibians, studies exploring the presence of the chytrid fungus (Batrachochytrium
dendrobatidis) and the effects of climatic change are badly needed to
understand the specific factors that negatively affect populations in this area. In
general, conservation efforts for reptiles and amphibians in the Yucata´n Peninsula
need to include environmental"
