The use of specimen label databases for conservation purposes: National Center for Biotechnology InformationU. Finally, at the finest scale of 0. Ethnobotany in the Sierra Tarahumara, Mexico. Van Cchiapas, and Erik F.

Lithobates catesbeianus Shaw — Introduced. Afterwards, consensus maps were sometimes trimmed based on a literature review and knowledge of the region. GARP also gives a binary output presence—absence mapwhich aids in making a consensus of maps. Two of them in southwestern Chihuahua Phyllorhynchus browni and Pseudoficimia frontalis ; four in northeastern Chihuahua Coluber constrictorLampropeltis alternaPantherophis bairdiTantilla cucullata ; two in the northwestern part of the state Crotalus tigrisSistrurus catenatus ; and one in extreme chispas Chihuahua Tantilla atriceps.

Locality records for individual species were checked for geographical outliers and, in cases in which it appeared that a particular record was based on a misidentification or faulty locality date, it was removed from the database. Our goal is to place this checklist into a regional and conservation context not available in previously published checklists.

Finally, an understanding of the patterns, causes and consequences is fundamental to understanding the evolutionary processes speciation and ecological processes succession, community developmentas well as the dispersion and persistence, of species Levin, 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.

These results suggest that particular conservation attention should be paid to the Sierra Madre Occidental and the Chihuahuan Desert habitat types in Chihuahua.

The goal of this study was to compare the richness and endemism patterns of Mexican species of amphibians and reptiles at different spatial scales. Summary of species present in Chihuahua by family, order or suborder, and class.

At the finest scale of 0. Such is the case for the salamanders of Mesoamerica. Citing articles via Web of Science 8. However, it was not possible to appreciate the subtleties in the pattern of richness in northern Mexico probably because of the lack of locality records in this region, which was amended using species distribution models based on ecological niche.

It furthers the University’s objective of excellence in research, scholarship, and education by publishing worldwide. Coniophanes imperialisHerpetlfauna. Implications for conceptual models of urban watershed processes. The remaining seven endemic species are distributed mainly along the Pacific Coast of Mexico Anolis nebulosusCtenosaura macrolophaSceloporus albiventrisHdrpetofauna nelsoniUrosaurus bicarinatusPlestiodon parviauriculatusand Aspidoscelis costata.

Chihuahuan amphibians make up less of the species pool, especially salamanders. 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.

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

A total of species of hciapas and reptiles is found in Chihuahua. The Desert Spiny Lizard Sceloporus magister shows a range similar to that of the preceding species. Nevertheless, in other areas, it might be assumed that isolation and divergence have occurred at the level of entire communities because of the limited dispersal abilities of both groups.

These patterns of shared species are likely a function of the extent to which these states share habitat types. Colubridae from an isolated premontane forest in eastern Panama.

We list amphibians and reptiles for the chiapsa of Chihuahua, with their conservation status. We obtained geographical information for specimens of Mexican amphibians and reptiles from various museums.

Traditionally, it has been thought that the cause of pattern richness is an abundance of resources, such as net primary productivity e. The deepest canyon is Urique Canyon, 1, m in depth; Batopilas Canyon is 1, m deep; Sinforosa Canyon is 1, m deep; and Copper Chia;as is 1, m deep Martin et al.

We obtained records useful for analysis. Another 32 are distributed in the United States and Mexico, most of them are species characteristic of the Chihuahua Desert or woodlands of the Sierra Madre Occidental Elgaria kingiiGerrhonotus infernalisCrotaphytus collarisGambelia wislizeniiColeonyx brevisCophosaurus texanusHolbrookia elegansHolbrookia maculataPhrynosoma cornutumPhrynosoma modestumSceloporus bimaculosusSceloporus clarkiiSceloporus consobrinusSceloporus cowlesiSceloporus jarroviiSceloporus merriamiSceloporus poinsettiiSceloporus sleviniSceloporus virgatusUrosaurus ornatusUta stansburianaPlestiodon callicephalusPlestiodon multivirgatusPlestiodon obsoletusPlestiodon tetragrammusAspidoscelis exsanguisAspidoscelis gularisAspidoscelis inornataAspidoscelis marmorataAspidoscelis sonoraeAspidoscelis tesselataand Aspidoscelis uniparens.

State lists used to compare herpftofauna species composition between Chihuahua and the adjoining states were: Published online Feb All of this, together with new tools permitting the modelling herpetofauan the distribution areas of the species, has allowed us to obtain a more complete picture and has led to the re-analysis from new perspectives of the patterns of diversity and endemism.

General distribution Thirteen of the 38 species of amphibians that inhabit Chihuahua are endemic to Mexico, one 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.

Five more range from Canada to northern or central Mexico Opheodrys vernalisPituophis cateniferDiadophis punctatusThamnophis elegansand Thamnophis sirtalis. 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. Houghton Mifflin, Boston, pp. This prediction is fulfilled at any locality size different spatial scalesand there is always a larger number of species of reptiles than amphibians.

University of Arizona Press, Tucson, pp. Although it is impossible to entirely eliminate these biases by modelling, it diminishes their influence on the results. This result suggests that factors promoting endemism patterns differ between amphibians and reptiles or, as a result of their different ecologies, the same causal factor acts differently in each group. The initials of the variables come from herpetofauma Spanish translation.

The average of the local r 2 and the standard deviations from the GWR are reported to represent the general pattern.
