Summary of the numbers of species shared between Chihuahua and neighboring Mexican and American states not including introduced species. Climatic gradients in woody plant tree and shrub diversity: In Mexico, this latitudinal pattern of richness has been repeatedly observed e.

Our goal is to place this checklist into a regional and conservation context not available in previously published checklists.

Seidel mapped its range into Chihuahua, but only conjecturally. 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 Emydidae and Testudinae are the families of most conservation concern.

The level of taxonomic and biogeographical understanding and, especially, the integration of hrepetofauna relating to museum specimens have advanced significantly in recent years. Distributional patterns of the herpetofauna of Mesoamerica, a biodiversity hotspot. Oxford University Press is a department of the University of Oxford. Plethodontidae from eastern Panama, with comments of the adspersa species group from eastern Panama. Painter C, Stuart J. From the coarsest spatial scale maps for both amphibians and reptiles, it is possible to observe a clear latitudinal pattern of species richness Fig.

Two relatively large areas stand out for their reptile richness 51—70 species: Patterns of species richness and endemism of the amphibians and reptiles of Mexico have been studied by various researchers and hciapas basic understanding of these patterns is beginning to emerge.

In addition, the more locally appropriate EVS assessments see Wilson et al. This method allowed us to explore non-stationary relationships among variables i.

State lists used to compare the species composition between Chihuahua and the adjoining states were: Based on the distribution ranges obtained, richness maps were generated at different scales for the two groups.

The values were calculated with linear models LM for richness—endemism for comparative purposes only, and with geographically weighted regression GWR for all.

Journal of Herpetology Hardy and McDiarmid mapped localities for this species as Leptodactylus occidentalisa junior synonym from throughout the lowlands of Sinaloa, including a locality in the extreme northeastern corner. For reptiles, the richest areas 51—70 species are found from central Veracruz Los Tuxtlas fhiapas and central Guerrero Omiltemi—Chilpancingo region into southern Oaxaca and southward to central Chiapas Fig.

Two are from Coahuila, including one from the extreme northwestern corner, in the Sierra del Carmen Wilson Afterwards, consensus maps were sometimes trimmed based on a literature review and knowledge of the region. The above analyses demonstrate that the diversity patterns, richness and endemism, vary depending on the spatial scale of analysis in both groups.

Three species have been taken close to the state line with Sonora and Sinaloa, in the extreme southwestern part of the state. Hansen and Gerard T. There are at least nine lizard species not yet recorded in the state of Chihuahua that are likely to occur in it; four of them in the deep canyons and lowlands of extreme southwestern Chihuahua; three in the extreme northeastern part of the state; and two in the extreme northwestern part.

For herpteofauna, Chihuahua, Sonoraand Durango all have extensive desert habitats whereas Texas, for example, has a much more diverse range of habitats than Chihuahua. Even beyond these species and families, the environment and habitats of Chihuahua are subject to anthropogenic change, herprtofauna as herpetoafuna of border fences Lasky et al. Ethnobotany in the Sierra Tarahumara, Mexico.

Stebbins indicates occurrence of this species in the extreme southeastern corner of Arizona, and in eastern Sonora near the Chihuahua border. The distribution, ecology and evolutionary history of Plethodontid salamanders in tropical America. Derived climatic variables used during the niche modelling process. Another anuran species likely to occur in extreme northeastern Chihuahua is the Gulf Coast Toad Incilius nebulifer.

Twenty-five species occupy more than one habitat type i. Smith abab ; Lemos-Espinal and G. Phylogenetic composition of angiosperm diversity in the cloud forests of Mexico. Salvador and John O. Related articles in Web of Science Google Scholar. All of this, together with new tools permitting the modelling of the distribution areas of the species, has allowed us to obtain heepetofauna more complete picture chlapas has led to the re-analysis from new perspectives of the patterns of diversity and endemism.

Van Devender and Van Devender Forty-four are found in the subtropical canyons of the Sierra Madre Occidental.

Molecular Phylogenetics and Evolution The scale of values was homogenized into five groups, 1—10, 11—30, 31—50, 51—70 and 71—90, to compare patterns of richness and endemism between both groups.
