Anguidae from western Panama. Sierra del Nido, Chihuahua.

Based on previous studies, we assume that, if the factors behind the patterns of richness and endemism differ, these patterns at different scales do not necessarily have to retain similar congruence, because the herpetoafuna factors of each pattern — richness or endemism — are operating at different scales. In the former, rich areas remain when decreasing the grid size, whereas, in the latter, rich areas are diluted with decreasing grid size.

This result suggests that factors promoting endemism herpetoofauna differ between amphibians and reptiles or, as a result of their different ecologies, the same causal factor acts differently in each group. A polygon was generated for the geographical distribution of each species.

We therefore encourage additional emphasis be placed on better understanding the ecology and conservation status of turtle and tortoise populations in Chihuahua. SmithNayarit: Painter C, Stuart J.

Superscripts indicate herpetofaunq of introduced species to the state. SmithHidalgo: The goal of this study was to compare the richness and endemism patterns of Mexican species of amphibians and reptiles at different spatial scales. For comparative purposes, the scale of values located at the bottom of the figure was used in all cases.

Although there is a widespread feeling among researchers advocating that explanations associated with processes that generate patterns of distribution and therefore richness are general to a certain degree, there is chiapass which supports the possibility that there may be more than one mechanism involved in the generation of these patterns Gaston et al.

It furthers the University’s objective of excellence in research, scholarship, and education by publishing worldwide. General distribution Thirteen of cjiapas 38 species of amphibians that inhabit Chihuahua are endemic to Mexico, herpetofaunz of them Lithobates lemosespinali is restricted to a small area in the Sierra Madre Occidental of Chihuahua, and another Isthmura sierraoccidentalis is found only in an isolated population in the Sierra Madre Occidental of Sonora and Chihuahua.

Only one of the 51 lizard species that occur in Chihuahua is an introduced species Hemidactylus turcicus. Some of the data used in this report have been obtained from these funded projects. One hundred models were generated for each species, using different criteria depending on the number of unique locality records that were available. Among these states Chihuahua has received a great deal of attention in the study of its herpetofauna.
