Notably, areas of moderate richness are present along the Sierra Madre Oriental and Occidental. A phylogenetic perspective on elevational species richness patterns in Middle American treefrogs: Anderson CG, Greenbaum E. Annual Magazine of Natural History 15, No.

Amphibians and reptiles of the state of Chihuahua, Mexico, with comparisons with adjoining states

Van Devender, and Erik F. 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 evidence which supports the possibility that there may be more than one mechanism involved in the generation of these patterns Gaston et chaipas.

Predicting the impacts of climate change on the distribution of species: Smith abab ; Lemos-Espinal and G. Check List 11 3: The latitudinal gradient in geographical range: With this approach, conspicuous features have been discovered: It is highly likely that nine more snake species occur within the state of Chihuahua. Another four species range from northern Mexico to Central or even South America Boa sigmaMasticophis mentovariusImantodes gemmistratusand Agkistrodon bilineatus.

Distributional patterns of the herpetofauna of Mesoamerica, a biodiversity hotspot. Anguidae with comments on the herpetography of the highlands of southern Mexico. Eastern and Central North America. In terms of habitat types, 47 species are found in the temperate forests of the Sierra Madre Occidental.

Amphibians and reptiles of the state of Chihuahua, Mexico, with comparisons with adjoining states

Hedman and Myra C. Andrew Gottscho helped us with the map for the State of Chihuahua. Six more species occur from central or southern United States to northern Terrapene ornata [Fig.

Interestingly, for both groups, the lowest correlation between richness and endemism occurs at the finest spatial scale of 0. A total of native, two introduced species of amphibians and reptiles is found in Chihuahua.

Chihuahua is physiographically complex Fig. However, to explain latitudinal patterns, this hypothesis becomes redundant because there are more species towards the equator. Photo by Julio Lemos Espinal. Please review our privacy policy. University of California Press, Berkeley, pp https: Three more species are widely distributed from southern Canada to northern Mexico Ambystoma mavortiumAnaxyrus cognatusand Spea bombifrons. About 30 museum records were determined to be in error, usually because their purported provenance was far removed from their known distribution.

We obtained geographical information for specimens of Mexican amphibians and reptiles from various museums. Introduction Chihuahua is the largest state in Mexico. Does climate determine broad-scale patterns of species richness?

We also compare the list of the six adjoining states in the United States and Mexico for which recent checklists are available New Mexico, Texas, Coahuila, Durango, Sinaloa, and Sonora. Patrones de diversidad espacial en grupos selectos de especies.

Traditionally, it has been thought that the cause of pattern richness is an abundance of resources, such as net primary productivity e. Conant and Collins depicted the southern part of the Big Bend region of Texas as part of the range of the Reticulate Banded Gecko Coleonyx reticulatus. Bulletin of the Maryland Herpetological Society We are also grateful to R. Journal of Herpetology Devitt, Peter Heimes, Oscar Herpeetofauna.

In this sense, to have more species of reptile at the regional level nationwideone would expect local communities of reptiles to generally exhibit higher richness. A general assessment of the conservation status and decline trends of Mexican amphibians. We performed geographically weighted regressions for each of the four scales analysed to analyse the relationship between richness and endemism, and to take into account the spatial structure of the patterns.

In addition, the more locally appropriate EVS assessments see Wilson et al. This species of toad is represented by isolated populations at the southern extremity of the Big Bend region of Texas, adjacent to Coahuila Conant and Collins Leptodactylidae random or non-random?
