Well, It is not completely sure it is eewi. Anolis eewi was described from Toronó, part of Chimantá tepuy, the neighbor tepuy of Auyan, where this one was found. This individual was at the same altitude (around 2000 m) and conditions as eewi. Norops planiceps is a widespread species in northern South America, and is very variable, but the proportions and the general feeling of my nose as a taxonomist told me this was different. Probably the best way to present it is as cf. eewi, even now eewi is synonym of planiceps. Leer más.

La rambla del puerto de la Cadena es un lugar muy popular entre excursionistas. Pocos conocen, sin embargo, la rica fauna que habita este delicado ecosistema, declarado área de conservación prioritaria. Entre las especies que tienen aquí su hábitat destacan los anfibios, cuya presencia -o ausencia- «sirve para medir la calidad mediambiental de un entorno», afirma Paz Parrondo, bióloga de la asociación Columbares y coordinadora del Proyecto Amphibia, que trabaja en la conservación de los anfibios en el sureste ibérico.

Un equipo de biólogos del grupo de conservación y ecoturismo Tropical Herping se ha vuelto a topar con un ejemplar de una rara especie de ranas, cuya presencia en Ecuador fue documentada por última vez en 2005. La rana marsupial cornuda Gastrotheca cornuta ha sido vista en la selva tropical de Chocó, al oeste del país, concretamente en el entorno de la reserva ecológica de Cotacachi-Cayapas. Leer más.

Pablo Burraco Maider Iglesias-Carrasco Carlos Cabido Ivan Gomez-Mestre. Conservation Physiology, Volume 6, Issue 1. We found that leachates of eucalypt leaf litter reduced amphibian development and growth, compromised their antipredator responses and altered their metabolic rate. Increased temperature itself also posed serious alterations on development, growth, antioxidant ability and the immune status of tadpoles. However, the combined effects of eucalypt leaf litter and increased temperature were additive, not synergistic. Therefore, we show that non-lethal levels of a globally spread disruptor such as leachates from eucalypt leaf litter can seriously impact the life history and physiology of native amphibian populations.

Urbanization can cause species to adjust their sexual displays, because the effectiveness of mating signals is influenced by environmental conditions. Despite many examples that show that mating signals in urban conditions differ from those in rural conditions, we do not know whether these differences provide a combined reproductive and survival benefit to the urban phenotype. Our findings thus reveal that urbanization can rapidly drive adaptive signal change via changes in both natural and sexual selection pressures. Artículo en español . Leer más (fuente original).
