We want to thank John Legler and Richard Vogt for inviting us to the Symposium on Mexican Turtles at the 11th Turtle Survival Alliance TSA meeting, at which the original ideas for this paper were presented and discussed in an early stage. Annotated checklist of taxonomy, synonymy, distribution, and conservation status. Most of the under recognition between lists is related to misunderstandings probably ignorance or lack of information and a very slow information update process between official lists issued by Mexican Government agencies and the international lists generally issued by specialist groups.

Limits to the use of threatened species lists. The conservation status of the world’s reptiles. One consequence of these issues is threatened species and their associated conservation problems are attached to the jurisdictional and legal administration within countries, states, municipalities, counties, districts, etc.


A main goal should be to improve the congruence between the threatened categories of international and local lists, in order to meet obligations to focus research, funds, budgets, and other political efforts toward generating a benchmark of protection for such a diverse group of reptiles in the country.

We want to thank Michael T. Journal of the Arizona-Nevada Academy of Science. The answers to these questions should provide a clearer sense of whether including species on imperiled species lists i.

We decided to use only those records in order to follow what Mexican authorities should do for the protection of imperiled species in accord with the law currently. Conocimiento actual de la biodiversidad.

The ecology, exploitation and conservation of river turtles. The dazed and confused identity of Agassiz’s land tortoise, Gopherus agassizii Testudines, Testudinidae with the description of a new species, and its consequences for conservation.

This situation merits the following questions: There are no data available about G. Among all of these lists, potential good conservation coverage should be predicted for Mexican turtles; however, there are some inquiries that should be made in order to know more about Mexican non-marine turtles’ conservation status. The continental turtle fauna of Mexico is composed of 7 families, 13 genera, and 45 species; when subspecies are biologoa, a total of 61 distinct taxa are recognized.
