Leptodeira frenataNinia sebaeand Micrurus diastema. SmithNayarit: Among individual terrestrial vertebrate groups in Mexico, the most species-rich areas i. Patrones de diversidad espacial en grupos selectos de especies. The biogeography of the cloud forest herpetofauna of Middle America, with special reference to the Sierra de las Minas of Guatemala. As indicated in Stebbins and Degenhardt et al.

hepretofauna Evidence for a complex evolutionary history of mound building in the Australian nasute termites Nasutitermitinae. In addition, considering patterns at different scales of values one for each chiaps scalealpha areas may be distinguished, in which local richness is very important, and beta areas, in which replacement contributes more to herpetogauna richness see Supporting Information Figs S1, S2.

There are several additional species that are likely to occur in Chihuahua, but that have not been recorded within the state. Finally, at the finest scale of 0.

The scale of values was determined by Jenks natural breaks classification. Conant R, Collins JT. Oxford University Press is a department of the University of Oxford. However, to explain latitudinal patterns, this hypothesis becomes redundant because there are more species towards the equator. University of California Press, Berkeley, pp https: From these plains arise a large number of small to medium-sized, isolated sierras, some of which reach altitudes of over 2, m.


Colubridaewith comments on distribution and conservation. Phylogenetic history underlies elevational biodiversity patterns in tropical salamanders.

Landscape and Dhiapas Planning We assume that two groups with different characteristics, particular ecological requirements and dissimilar evolutionary histories will not share richness and endemism patterns, and that the factors that influence their distribution and the structure of their communities will be different.

Leptodactylidae random or non-random? Chihuahua shares the highest proportion of its herpetogauna with Sonora and Durango. Crotalus ornatus Eastern Black-tailed Rattlesnake. Indeed, there are species, such as Craugastor tarahumaraensisCtenosaura macrolophaUma paraphygasand Tropidodipsas repleta that are of great conservation concern based on their EVS values Wilson et al. Topographical map of the state of Chihuahua, Mexico: Lithobates catesbeianus Shaw — Introduced.

This was accomplished with the help of Arc View 3. Receive exclusive offers and updates from Oxford Academic.

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

Apalone spinifera Le Sueur. COI barcoding suggests underestimated taxonomic richness in a threatened endemic fauna. Species were included in the checklist only if we were able herptofauna confirm the record, either by direct observation or through documented museum records or vouchers in the state.

Heroetofauna online Feb The need for continued scientific collecting: We also included variables of aspect, slope, topographic index and model of digital elevation US Geological Survey, Subspecies were not used in the analyses.

Open in a separate window. Van Devender, and Erik F. Devitt, Peter Heimes, Oscar A.

In addition, the more locally appropriate EVS assessments see Wilson et al. We obtained geographical information for specimens of Mexican amphibians and reptiles from various museums. Three other regions are noteworthy because of their number of endemic reptiles 31—50 species: Craugastoridae in Costa Rica.

We therefore encourage additional emphasis be placed on better understanding the ecology and conservation status of turtle and tortoise populations in Chihuahua. Smith aand Lemos-Espinal et al. We used the best available dataset of distributional ranges generated from ecological niche chiiapas and employed geographically weighted regressions GWRs to test whether richness and endemism were related.

Bulletin of the American Museum of Natural History These represent 32 families: Emydidae and Testudinae are the families of most conservation concern. A decrease in the number of species occurs in reptiles towards the centre of the country, which is surrounded by relatively species-rich areas at moderate elevations in the mountains.

The goal of this study was to compare the richness and endemism patterns of Mexican species of amphibians and reptiles at different spatial scales. The goal of this study is to independently analyse the influence of spatial scale on patterns of richness and endemism of Mexican amphibians and reptiles and then to compare these two groups of vertebrates. The topography of the Sierra Madre Occidental of Chihuahua is very heterogeneous.

Oedipina from the central Caribbean foothills of Costa Rica. The chronological distribution of these publications is the following: Pr – subsp baileyi. Four of these six canyons are deeper than the Grand Canyon, some by over m.
