Today, May 23rd, is World Turtle Day. It is a day of celebrating the many unique and ancient species of turtles and tortoises around the world, and bringing awareness to their need for protection. Of the 207 species of turtle and tortoise alive today, 129 of them are listed by IUCN as vulnerable, endangered, or critically endangered. That’s an incredibly 62% of species! Leer más.
Whenever I stand in the forest on South Bimini in the Bahamas, I’m always struck by the similarity of these anoles to those I’ve worked with elsewhere in the Greater Antilles. Yes, that’s the whole idea behind the ecomorph concept, but as many have pointed out recently, habitat use and morphological convergence are only part of the story. Leer más.
L’Institut Català de Paleontologia (ICP) ha iniciat aquest dilluns la campanya d’excavacions a les comarques de Lleida i ho ha fet a Coll de Nargó (Alt Urgell) on s’ha trobat un esquelet d’un petit vertebrat.

While glaciations constituted the major recent paleoclimatic event, inducing multiple oscillations on species’ ranges, future and rapid shifts are expected if global warming predictions are confirmed. Investigating the whole temporal spectrum of range shifts is of conservation importance since species suffering contractions during the interglacial periods may continue contracting in a warming scenario; lizards provide excellent models for such analysis.
