Distribución y abundancia de Craugastor vulcani: una especie de rana en riesgo de Los Tuxtlas, Veracruz, México Distribution and abundance of Craugastor vulcani: an endangered frog species from Los Tuxtlas, Veracruz, Mexico

  title={Distribuci{\'o}n y abundancia de Craugastor vulcani: una especie de rana en riesgo de Los Tuxtlas, Veracruz, M{\'e}xico Distribution and abundance of Craugastor vulcani: an endangered frog species from Los Tuxtlas, Veracruz, Mexico},
  author={Eduardo Jim{\'e}nez Pineda and Clara A. Rodr{\'i}guez-Mendoza},
More than a half of all amphibian species occurring in Mexico are threatened, and for most of them there is no current information to assess the status of their populations. Craugastor vulcani is an endemic frog from the Los Tuxtlas mountains, Veracruz, and it is classifi ed as an endangered species. We examine the distribution and abundance of C. vulcani as a function of rainforest transformation in Los Tuxtlas. We consulted historical records in databases and sampled 12 sites representing… Expand


Herpetofauna diversity and microenvironment correlates across a pasture–edge–interior ecotone in tropical rainforest fragments in the Los Tuxtlas Biosphere Reserve of Veracruz, Mexico
Abstract We evaluated the relationship between amphibian and reptile diversity and microhabitat dynamics along pasture–edge–interior ecotones in a tropical rainforest in Veracruz, Mexico. To evaluateExpand
Tropical rain forest fragmentation and wild populations of primates at Los Tuxtlas, Mexico
In view of the extensive destruction, fragmentation, and conversion of primate habitats to anthropogenic vegetation, information on Neotropical primate ability to use a landscape consisting of forestExpand
Rates of Deforestation in Los Tuxtlas, a Neotropical Area in Southeast Mexico
Abstract: On the basis of ground surveys, aerial photographs (for 1967 and 1976), and satellite imagery (for 1986), maps of rain forest distribution were developed for the northern part of the SierraExpand
Effects of conversion of dry tropical forest to agricultural mosaic on herpetofaunal assemblages.
The decline in abundance of disturbance-sensitive species was associated with the reduction of forest canopy cover, woody stem cover, roots, and litter-layer ground cover in Neotropical dry forests. Expand
Species diversity and habitat fragmentation: frogs in a tropical montane landscape in Mexico
Elevational variation, the degree of conservation of the vegetation canopy and fragment size appear to determine the species diversity of this landscape, and large species, terrestrial species, those whose eggs develop outside water, and those whose larvae develop in the water seemed to be most affected by habitat transformation.

This study proposes a simple approach to estimate model performance for several distributional predictions generated simultaneously, particularly suitable when species distribution modelling techniques that require only presence data are used. Expand
Matrix habitat and species richness in tropical forest remnants
Positive and significant correlations between matrix abundance and vulnerability to fragmentation are exhibited, suggesting that species that avoid the matrix tend to decline or disappear in fragments, while those that tolerate or exploit the matrix often remain stable or increase. Expand
Paradox, presumption and pitfalls in conservation biology: The importance of habitat change for amphibians and reptiles.
A global scale review of the state of research regarding the consequences of structural habitat change for amphibians and reptiles reveals a number of serious deficiencies, and suggests that the study of habitat change is deserving of considerably more attention. Expand
Amphibian Population Declines in Latin America: A Synthesis1
The loss of global amphibian biodiversity has been well documented in recent years. The greatest information from Latin America came from countries such as Costa Rica, Panama, Ecuador, and PuertoExpand
Computer tools for spatial analysis of plant genetic resources data: 1. DIVA-GIS
The DIVA-GIS software allows analysis of genebank and herbarium databases to elucidate genetic, ecological and geographic patterns in the distribution of crops and wild species to improve data quality. Expand
