No new males: Climate change threat to Cape Verde turtles
Rising temperatures could mean no male loggerhead turtles hatch at a key breeding ground by the end of this century, new research suggests. Leer más.

Diasporus amirae • A New Species of Dink Frog, Genus Diasporus (Anura: Eleutherodactylidae), from the Caribbean foothills of the Cordillera de Talamanca, Costa Rica
A new dink frog (Eleutherodactylidae: Diasporus) is described from the Tropical Wet Forest, in the northeastern foothills of Cordillera de Talamanca in Costa Rica at an elevation of ca. 1000 m. Analysis of DNA sequences of the 16S rRNA (16S) and cytochrome oxidase 1 (COI) mitochondrial genes revealed a distinct lineage within the genus Diasporus. Additional morphological, morphometric, and acoustic analyses support the differences of this lineage, which we recognize as a new species. Leer más.ç

Es re-introdueixen més de 600 tortugues mediterrànies (Testudo hermanni) al Parc del Garraf.
En el marc del programa de reintroducció de la tortuga mediterrània occidental (Testudo hermanni hermanni), enguany al Parc del Garraf s'han alliberat un total de 660 tortugues mediterrànies per tal de reforçar-ne les poblacions en el massís. Les tortugues alliberades procedeixen de la recuperació i cria en captivitat duta a terme al Centre de Recuperació d'Amfibis i Rèptils de Catalunya (CRARC), d'individus aportats pel Centre de Reproducció de Tortugues de l'Albera, i de les instal·lacions de cria gestionades per particulars, en col·laboració amb el Departament de Territori i Sostenibilitat de la Generalitat de Catalunya, entre elles el Zoo de Barcelona.

We have developed a new software, APHIS, for photo-matching that minimizes the pre-processing time and maximize the speed of the matching procedure. APHIS can process photos in batches of hundreds and users can select between two alternative matching procedures, one interactive (SMP), built as an extension of existing and freely available software, and one authomatic (ITM).

El cangrejo rojo americano incrementa la infección del hongo quitridio en anfibios
La quitridiomicosis es una enfermedad que está diezmando las poblaciones de anfibios de todo el planeta. Identificar los potenciales reservorios biológicos del hongo quitridio es esencial para establecer estrategias de control de la enfermedad. Un estudio liderado por la Estación Biológica de Doñana indican que el cangrejo rojo americano es un reservorio de la enfermedad. Leer más.

Symposium: Global amphibian population declines: 30 years of progress in confronting a complex problem
Sep. 20, 8:30 a.m. – 06:00 p.m. Redpath Museum, 859 Rue Sherbrooke Ouest, Montréal, QC. In 1989, at the landmark 1st World Congress of Herpetology, scientists first became concerned that observations of declining or lost amphibian populations were not simply isolated incidents but were global in scope and severity. The plight of amphibians became front-page news and the newly generated interest in their population biology generated a massive increase in our understanding of their ecology, epidemiology and conservation biology. To mark 30 years of research into amphibian population declines and Canada's pivotal contributions to this important research initiative, we are holding an international symposium on amphibian ecology and conservation biology to bring together many of the principle researchers now making significant advances in the field.
