First report of melanism in the salamander Bolitoglossa rufescens (Caudata: Plethodontidae) in Veracruz, México

Several cases of pigmentary abnormalities have been documented in salamanders. These abnormalities can be partial or total and are derived from the absence or excess of pigmentation produced by chromatophores (pigment cells). Here, we present the first record of melanism in the salamander Bolitoglossa rufescens, from Veracruz, Mexico, being this the second case of abnormal pigmentation in the genus Bolitoglossa.Asociación Herpetológica Argentin

Depredación por larva de escarabajo de agua (Coleoptera: Dytiscidae) y canibalismo en Lithobates berlandieri (Anura: Ranidae) en Huatusco, Veracruz, México

Documentamos por primera vez, un evento depredatorio junto con canibalismo, donde dos renacuajos de Lithobates berlandieri se acercaron al cuerpo de un renacuajo mientras era depredado por la larva de ditíscido y también se alimentaron del mismo. Este caso de canibalismo sugiere una respuesta competitiva.We documented for the first time, a depredatory event along with cannibalism, where two tadpoles of Lithobates berlandieri approached to the body of a tadpole while being predated by the larva of dytiscid and fed on it.
