Tim Halliday obituary
The recent shocking UN report on the threatened extinction of one million species has focused global attention on the crucial role of biodiversity in the health of the planet. Almost exactly 30 years ago, the first warning sounded that amphibian species were already in potentially catastrophic freefall. Tim Halliday, who has died aged 73, was one of the leading figures in a worldwide initiative to raise the alarm, and to understand the reasons for the decline. The current chief scientist of the Amphibian Survival Alliance, Phil Bishop, called him "the leading champion and ambassador for all things amphibian". Leer más.

Behavior in a Changing Landscape: Using Movement Ecology to Inform the Conservation of Pond-Breeding Amphibians
Movement, both within an individual's home range and at the scale of dispersal, is a fundamental aspect of an animal's life. The field of movement ecology has established a conceptual framework to analyze the lifetime movement of an organism, offering a sound basis for conservation actions since the movement range of many species has been altered by habitat fragmentation and degradation.

Monitorización de metales pesados en reptiles mediante métodos no invasivos
La monitorización de reptiles en estas áreas contaminadas puede por tanto suponer un indicador del riesgo de exposición de otros grupos de fauna silvestre. En este estudio analizamos la exposición de galápagos leprosos a plomo (Pb) y mercurio (Hg) en las zonas mineras del sur de Ciudad Real con el propósito de validar el uso de heces y de piezas desprendidas de la capa epidérmica del caparazón como métodos no invasivos de monitorización de estos metales.

APRENEM COM AVALUAR LA QUALITAT ECOLÒGICA D’UNA BASSA
El passat dissabte dia 4 de maig, més d'una vintena de persones van apropar-se a la bassa del Puig dels Jueus (Vic) per participar a la sortida "Els amfibis i altres habitants de la bassa". Una jornada centrada en la fauna que habita la bassa, sobretot amfibis i invertebrats aquàtics, però posant atenció també en els ocells i la vegetació acompanyants. L'activitat va permetre comprovar que la bassa, recentment restaurada, ja ha estat colonitzada per un bon nombre de grups d'éssers vius. Leer más.

Effects of historic and projected climate change on the range and impacts of an emerging wildlife disease
These results, combined with climate projections, predict severe ranavirosis outbreaks will occur over wider areas and an extended season, possibly affecting larval recruitment. Since ranaviruses affect a variety of ectothermic hosts (amphibians, reptiles, and fish), wider ecological damage could occur. Our three complementary lines of evidence present a clear case for direct environmental modulation of these epidemics and suggest management options to protect species from disease. Leer más.
