Abra de Zamora is an important biodiversity hotspot in southern Ecuador. Between 1938 and 2010, eleven species of frogs were described from here: Lynchius flavomaculatus, Gastrotheca psychrophila, Pristimantis balionotus, P. colodactylus, P. cryptomelas, P. percultus, P. versicolor, P. vidua, Telmatobius cirrhacelis, P. andinognomus, and Atelopus podocarpus. Unfortunately, many of these species were not re-encountered after their original description, and for the majority DNA samples were not available, making their phylogenetic position unknown.

En raison de l’épidémie de COVID-19 toujours en cours, nous sommes au regret de vous informer de l’annulation du 48ème congrès national d’herpétologie, qui devait se tenir à Lille du 8 au 10 octobre prochains. La SHF souhaite remercier chaleureusement le Groupe Ornithologique et Naturaliste du Nord-Pas-de-Calais, co-organisateur, pour son implication et son investissement. Leer más.
The reduction in fecundity associated with the evolution of viviparity may have far-reaching implications for the ecology, demography, and evolution of populations. The evolution of a polygamous behaviour (e.g. polyandry) may counteract some of the effects underlying a lower fecundity, such as the reduction in genetic diversity. Leer más.
Scientists have detected signs of a frog listed extinct and not seen since 1968, using an innovative technique to locate declining and missing species in two regions of Brazil. Leer más.
Researchers studied the evolution of the body sizes of frogs and their tadpoles. They found that the two life stages do not evolve completely independently of each other as previously thought. Leer más.
