Tres nuevas especies de la familia Microhylidae fueron descritas por investigadores colombianos, del Instituto Amazónico de Investigaciones Científicas (Sinchi) y del Instituto de Ciencias Naturales de la Universidad Nacional de Colombia, así como de la Universidad de Richmond, en Estados Unidos. Así son las ranas. Leer más.

We hypothesized that Ptyodactylus guttatus (Sinai Fan-fingered Gecko) individuals, which occupy the Mediterranean and desert biomes across Israel, would follow the “metabolic cold adaptation” hypothesis and be adapted to the microclimate in the biome they inhabit. Leer más.
Many species of sphaerodactyl gecko exhibit sexual dichromatism. In particular, dichromatism plays an important role in intersexual signaling for Sphaerodactylus. Furthermore, some species exhibit polymorphism in male color and pattern. Here, we describe a regional male color morph of Sphaerodactylus macrolepis from St. Croix. Leer más.
To answer this question, I will tell you the story of the Reptiles of Ecuador book, a meticulously created field guide that has gained attention due to its expansive scope, novel photographic style, open-access nature, and funding strategy. Leer más.
Physiological and metabolic performance are key mediators of the functional response of species to environmental change. Few environments offer such a multifaceted array of stressors as high-altitude habitats, which differ markedly in temperature, water availability, UV radiation and oxygen pressure compared to low-altitude habitats. Species that inhabit large altitudinal gradients are thus excellent models to study how organisms respond to environmental variation. Leer más.
