El destino unió al paleontólogo Adán Pérez García con las tortugas, pero no con las actuales, sino con las que poblaron la Península Ibérica en la era de los dinosaurios. A pesar de ser lentas y pesadaaxs, estos reptiles arrastran en sus caparazones más de 220 millones de años sobre la faz de la Tierra, lo que representa un éxito evolutivo poco frecuente entre las especies animales. Pérez García acaba de defender una tesis doctoral sobre estos reptiles durante el Mesozoico, y los fósiles encontrados en los yacimientos paleontológicos turolenses constituyen un registro valiosísimo.

Fossilized imprints and trackways record the movement and behavior of species long extinct. An amateur paleontologist discovered a fossil that has allowed others to follow the steps of a tiny 315-million year old tetrapod from the Carboniferous period. Leer más.
Species distributions are influenced by many processes operating over varying spatial scales. The development of species distribution models (SDMs), also known as ecological niche models, has afforded the opportunity to predict the distributions of diverse taxa across broad geographic areas and identify variables that are potentially important in regulating these distributions.

The Endangered Species Act (ESA)—the key US law protecting species listed as threatened or endangered—focuses on boosting species’ numbers until they reach recovery thresholds and so can be taken off the ESA list. Almost 1400 species are now listed. Leer más.
Chytridiomycosis, a fungal skin condition, is threatening remaining populations of unique amphibian species in the Caribbean. One of the most cherished of these is the large ‘Mountain chicken’ that holds a special cultural importance in Dominica, but it is now Critically Endangered. Leer más.
