Butterflies are important pollinators and indicators of environmental health. Habitat
destruction and fragmentation caused by developmental activities and poor natural resource …

We present a taxonomic, spatial, and thematic overview of the current state of knowledge on
helminth parasites of Mexican amphibians. Sixty-six host species have been studied so far …

Abstract The State of Mexico has a unique combination of geographic characteristics and
topography that promotes a high biodiversity. Unfortunately, continued human population …

Widespread species with morphologically and ecologically differentiated populations are
key to understand speciation because they allow investigating the different stages of the …

Biological nomenclature is an essential tool for storing and retrieving biological information.
Yet traditional nomenclature poorly reflects evolutionary theory. Current biological …

Los ajolotes de arroyos de alta montaña (Ambystoma), forman parte de especies
vulnerables debido a la naturaleza de su distribución, la cual se restringe a pequeños …

Amphibians are vulnerable to extinction due to their need for both terrestrial and aquatic
habitats to complete their life cycles. Some of them occupy urban areas, thus human …

Facultative or obligate paedomorphosis has evolved several times in Mexican populations
of the salamander genus Ambystoma, leading to increased genetic divergence among …

The loss of genetic diversity in small or isolated populations can increase inbreeding,
decrease fitness and adaptive potential and increase a species' probability of extinction. In …

Genetic characterization of species using phylogeographic approaches represents a basic
reference to understand their evolutionary history as well as to identify conservation …
