Persisting at the Edge of Ecological Collapse: The Impact of Urbanization on Fish and Amphibian Communities From Lake Xochimilco Open
Freshwater ecosystems are globally threatened by habitat loss, pollution, and invasive species, all of which are particularly acute in urban areas. To assess the impacts of urbanization on freshwater biodiversity—specifically the effects o…

The ultimate challenge to climate change: Endurance of a thermophilic reptile to the harsh temperatures on an extremely hot island Open
Herbivorous ectotherms are especially vulnerable to climate change and those inhabiting hot environments may already live near their maximum physiological limits. Insular species are particularly susceptible to changing thermal conditions …

Unpredictable aggressive defence of the venomous snake, <i>Crotalus ravus</i>, towards predators and humans Open
Antipredation behaviour is of high importance for the survival of prey animals, but it is also vital for the predator to understand the antipredator behaviour of potentially dangerous prey. Venomous snakes are particularly dangerous for th…

What factors influence the rediscovery of lost tetrapod species? Open
We created a database of lost and rediscovered tetrapod species, identified patterns in their distribution and factors influencing rediscovery. Tetrapod species are being lost at a faster rate than they are being rediscovered, due to slowi…

Cave-Dwelling Populations of the Monstrous Rainfrog (Craugastor pelorus) from Mexico Open
Amphibians are known cave dwellers, and a few anurans have shown to make exploratory or opportunistic use of subterranean environments. We report on the use of karst ecosystems and cavernicolous environments by the monstrous rainfrog Craug…

Lungworm parasite intensity and its association with the endocrine and immune systems and energy reserves in male cane toads Open
Host-parasite interactions can be harmful or harmless depending on the fitness and stress levels of the organisms. Interactions between the endocrine system, the immune system and energy expenditure are critical in the maintenance of homeo…

Bat Species Diversity and Abundance of Trophic Guilds after a Major Hurricane along an Anthropic Disturbance Gradient Open
The frequency and intensity of hurricanes have increased with climate change, and their effects on most taxa are not known. We analyzed a species diversity of bats in three locations with different regimes of anthropic disturbance. We asse…

Lightly-harvested rustic cocoa is a valuable land cover for amphibian and reptile conservation in human-modified rainforest landscapes Open
The conservation of tropical biodiversity depends not only on forest remnants, but also on anthropogenic land covers. Some shade crops are considered wildlife-friendly agroecosystems, but their conservation value is context- and taxon-depe…

A new large tortoise from the early Oligocene (Arikareean NALMA) of Oaxaca, southern Mexico and its phylogenetic position within <i>Pan-Testudinidae</i> Open
Pan-Testudinidae is the total clade of extant terrestrial tortoises, which includes extinct fossil members of their stem lineage. Members of this clade have a rather scarce fossil record in Mexico, and the few specimens known in sci…

Good alimentation can overcome the negative effects of climate change on growth in reptiles Open
Climate change may lead to higher nest temperatures, which may increase embryo development rate but reduce hatchling size and growth. Larger body size permits better performance, making growth an important fitness trait. In ectotherms, gro…

The fossil record of turtles and tortoises (Testudines) of Mexico, Central America and the Caribbean Islands, with comments on its taxonomy and paleobiogeography: a bibliographic review Open
Testudines is the crown-group that includes all living forms of turtles and their closest relatives. This group is known from the late Triassic and persists to this day. The fossil record of Testudines in Mexico is scarce and has been prev…
