Effects of Anthropogenic Disturbance of Natural Habitats on the Feeding Ecology of Moorish Geckos

Results showed that seminatural habitats differed from actual natural habitats in some microhabitat characteristics and in diversity of available prey. The diet of geckos also differed between habitats, being less diverse in altered habitats. However, the health state (body condition) of geckos was similar between habitats. These geckos seem able to modify their diet selection patterns to cope with anthropic disturbances of the habitat, which would allow them to inhabit and prosper in human-altered ecosystems.

Size-Mediated Trophic Interactions in Two Syntopic Forest Salamanders

We found that the foraging activity of S. perspicillata is positively affected by body size and negatively affected by potential competitor’s activity on the forest floor during the sampling, which also significantly weakened the positive relationship with body size. These results suggest the presence of an interference/interaction occurring between the two species and affecting the foraging activity of S. perspicillata. This competitive interaction is size mediated and configured as interference competition rather than exploitative competition. Leer más.

Descubren que el canibalismo de las salamandras gigantes americanas aumenta en áreas deforestadas

Un estudio realizado durante 8 años sobre las salamandras gigantes americanas (‘Cryptobranchus alleghaniensis’) que viven en los ríos fríos y rocosos del suroeste de Virginia (EE.UU.) indica que los machos de la especie consumen cada vez más a sus propias crías en áreas cercanas a bosques talados.

Selvasaura candesi • A New Species of Microteiid Lizard (Gymnophthalmidae: Cercosaurini) from A Remote Area in the Peruvian Andes

We describe a new species of Selvasaura lizard from the western slopes of the eastern Andes of central Peru. Among other characters, the new species differs from congeners in having keeled dorsal scales and more transverse rows of scales on dorsum. We present a phylogeny as additional evidence supporting delimitation of the new species. Leer más.
