Here, we use records between 1998 and 2024 to document the occurrence of a native population of the turtle Kinosternon leucostomum leucostomum (Duméril & Bribon in Duméril & Duméril, 1851) in the Central Depression of Chiapas, Mexico. Morphological measurements are provided to characterize variation among individuals. We report 22 individuals, whic...

The salamander Dendrotriton megarhinus (Rabb, 1960) (Caudata, Plethodontidae), previously known only from Cerro Tres Picos in La Sepultura Biosphere Reserve, Chiapas, Mexico, has been found at Cerro La Bola, Chiapas, extending its geographic range. In this report we provide four new records and outline aspects of the species’ ecology as well as thr...

The Central American river turtle (Dermatemys mawii) is one of the of the most critically endangered turtle species worldwide, as a result of habitat loss and heavy hunting for consumption. Research on D. mawii becomes more challenging as wild populations are disappearing, while basic ecological data are still required to inform conservation effort...

The snake Mastigodryas dorsalis (Bocourt, 1890) is generally considered absent from Mexico, but a few sources indicate otherwise. Herein we resolve this issue by re-examining a historical specimen and by reporting new records for M. dorsalis in Chiapas, Mexico. These records extend the known distribution of the species 87 km northwest of the neares...

In this study, we document the prevalence and intensity of Batrachochytrium dendrobatidis infection in a population of the Chimalapas Toad (I. tutelarius) in southern Mexico.

Habitat loss is one of the most important threats to biodiversity; it alters the habitat connectivity of species and is among the main causes of the global amphibian extinction crisis. Identifying the potential areas of distribution and connectivity of species is of the utmost importance so that informed decisions can be made for the conservation o...

The biodiversity data typically available for fitting distributional models in the tropics come from museum and scientific collections which are often incomplete and prone to sampling and environmental biases. Nevertheless, most studies undertaken in tropical regions assume that collection data offers a satisfactory environmental coverage without a...

Biodiversity loss is one major outcome of human-mediated ecosystem disturbance. One way that humans have triggered wildlife declines is by transporting disease-causing agents to remote areas of the world. Amphibians have been hit particularly hard by disease due in part to a globally distributed pathogenic chytrid fungus (Batrachochytrium dendrobat...

Only two species of Ixalotriton, I. Niger and I. parvus, are currently known, and both are endemic to small regions of Chiapas, México. An additional population of black Ixalotriton has recently been reported from caves on Cerro Baúl, near the only known locality of I. parvus. We conducted morphological and molecular analyses of animals from the ne...

The PREDICTS project—Projecting Responses of Ecological Diversity In Changing Terrestrial Systems (www.predicts.org.uk)—has collated from published studies a large, reasonably representative database of comparable samples of biodiversity from multiple sites that differ in the nature or intensity of human impacts relating to land use. We have used t...

Abstract The taxonomic diversity of trees, edible herbs, insects, fish, birds, amphibians, reptiles and mammals were studied; as well as the genetic diversity of mammals and trees in the nucleo and buffer zone of the REBISO. Moreover, the relationship of biodiversity with a capitals index (human, cultural, social, political, natural, physicalbuilt...

Background: Neotropical lizards, genus Anolis (Polychrotidae), with nearly 380 species, are members of one of the most diversified genera among amniotes. Herein, we present an overview of chromosomal evolution in 'beta' Anolis (Norops group) as a baseline for future studies of the karyotypic evolution of anoles. We evaluated all available informati...

Standard karyotypes of two species of the genus Scincella, S. assata and S. cherriei, both from Chiapas State, Mexico, were described for the first time. The diploid chromosome number was 28 in S. assata, whereas 30 in S. cherriei. The karyotypes of the two species, while differing in the number of microchromosomes, 14-15 in S. assata and 16-17 in...

Abstract. The transformation of complex native habitats through simpler and managed habitats like crops or grasslands implies a direct effect on species abundance. Agrosystems like diversified shade coffee crops (commonly named rustic cafetales) have been described as suitable habitats or refuge for many vertebrate species, which enhance or increas...

Effective and targeted conservation action requires detailed information about species, their distribution, systematics and ecology as well as the distribution of threat processes which affect them. Knowledge of reptilian diversity remains surprisingly disparate, and innovative means of gaining rapid insight into the status of reptiles are needed i...

Aim Montane Central America offers an ideal system for testing geographical hypotheses of species diversification. We examined how the complex geological history of Nuclear Central America has shaped the diversification of a genus of cloud-forest-inhabiting salamanders (Dendrotriton). We applied parametric models of geographical range evolution to...

Assessing Biodiversity Declines Understanding human impact on biodiversity depends on sound quantitative projection. Pereira et al. (p. 1496 , published online 26 October) review quantitative scenarios that have been developed for four main areas of concern: species extinctions, species abundances and community structure, habitat loss and degradati...

We studied the reproductive characteristics of sympatric populations of Sceloporus formosus scitulus, Sceloporus omiltemanus (Phrynosomatidae), and Mesaspis gadovii (Anguidae) at the Omiltemi forest reserve (Guerrero, Mexico). Males are larger and reach larger body sizes at reproductive maturity and are more colorful than females in both Sceloporus...

Fragmentation and the transformation of natural habitat are the primary factors that promote the loss of biodiversity. However, there are some kinds of land management that may be less aggressive with the environment. Some of these are agrosystems such as coffee crops, which have been considered biodiversity refuges. In this work, we examine lizard...

[Results from 2007 symposium.] The Alliance for Zero Extinctions (AZE) has identified some of the sites requiring urgent conservation attention to avoid the extinction of the species that inhabit in them. Several such sites have been identified in the northern portion of Central America, and the majority of them do not have any kind of official p...

According to IUCN´s red list, about a third of the planet's amphibian species are under threat. The main threat is habitat loss, and this is now reinforced by the chytrid fungus epidemic that has strongly affected the populations of some species in Mesoamerica. In this symposium several projects were presented, all of which are dealing with amphibi...

Declines of amphibian populations have been well documented in the US, Canada, and Central America, but little is known regarding the status of amphibian populations in Mexico. In 2000, we surveyed 43 transects from 3 upland regions in Guerrero and Oaxaca, Mexico. We found 161 adult amphibians belonging to 39 species, representing only 19–48% of th...
