La víbora hocicuda es una especie discreta y ampliamente distribuida por la Península Ibérica. Pero su extrema rareza y las malas relaciones con el ser humano mantienen algunas incógnitas sobre su biología y, sobre todo, plantean una pregunta de difícil respuesta: ¿es posible planificar su conservación?

The study suggests that human-facilitated introductions from various geographical origins, with numerous regions colonized through continental Italy during two distinct periods, are responsible for the recurrent entry of individuals belonging to the European lineage of T. mauritanica into the Mediterranean and Macaronesia.

Results were compatible with a TSD pattern with males generated at low and females at high incubation temperatures. Estimated pivotal temperature coincided with the temperature producing lower embryonic mortality, evidencing selection towards balanced sex ratios. Leer más.
Midwife Toads The Genus Alytes: History, Ecology, Systematics, Captive Breeding (2023). Midwife toads of the genus Alytes form a small group of primarily Iberian anurans. These fascinating toads hold cultural and scientific recognition on account of their distinctive, bell-like peeping call and their unusual strategy of paternal care, all of which trump their small, brown appearance and the rarity of encountering them in the wild.

Physiological and metabolic performance are key mediators of the functional response of species to environmental change. Few environments offer such a multifaceted array of stressors as high-altitude habitats, which differ markedly in temperature, water availability, UV radiation and oxygen pressure compared to low-altitude habitats. Species that inhabit large altitudinal gradients are thus excellent models to study how organisms respond to environmental variation. Leer más.
