The Persian dwarf snake Eirenis (Pseudocyclophis) persicus (Anderson, 1872) has a wide distribution range in south-western Asia. This species group was comprehensively studied here using traditional biometry, geometric morphometrics, ecological niche modelling, and genetics. Our analyses revealed that E. persicus is split into two clades. Leer más.

The second in our series of posts highlighting frontline conservation work brings us to Côte d’Ivoire. Project Mecistops team leader, Dr Matthew Shirley of the Rare Species Conservatory Foundation, goes in search of Critically Endangered West African slender-snouted crocodiles (Mecistops cataphractus) on the Bandama River in Azagny National Park.

En el caso de Doñana, que es el principal objeto de estudio de Díaz Paniagua, la investigadora observa ya problemas relacionados con el cambio climático. «El incremento de la temperatura afecta al periodo de reproducción de los animales y a la duración de las lagunas. Ese aumento hace que las especies puedan adelantar su periodo de reproducción y que una helada acabe con sus larvas», explica. Leer más.

Fresh analysis of a reptile fossil is helping scientists solve an evolutionary puzzle — how snakes lost their limbs. The findings show snakes did not lose their limbs in order to live in the sea, as was previously suggested. Leer más.

Knowledge about the types of nests built by dinosaurs can provide insight into the evolution of nesting and reproductive behaviors among archosaurs. However, the low preservation potential of their nesting materials and nesting structures means that most information can only be gleaned indirectly through comparison with extant archosaurs.
