The strong philopatry of juveniles contrasts with the frequently higher dispersal rate in young birds and mammals and shows the relevance of investigating dispersal in various taxonomic groups. Our results provide useful information for the conservation of European pond turtle populations. Leer más.
Most Croaking Science readers will be aware that the Global Amphibian Assessment of 2004 (GAA1: Stuart et al., 2004) found that about one third of amphibian species worldwide were in the IUCN’s ‘threatened’ categories (vulnerable, VU; endangered, EN; or critically endangered, CR), compared to only 12% of birds and 23% of mammals, making amphibians the worst off of the terrestrial vertebrates so far assessed (reptiles had not been assessed at that time). How has the situation changed in the nearly two decades since then? Leer más.
Just Add Water is a national campaign to encourage the public to dig wildlife ponds, especially in urban environments. In some areas this can counteract the enormous loss of countryside ponds in recent years, and help local frogs, newts and other wildlife flourish. Leer más.
Functional connectivity across fragmented habitat patches is essential for the conservation of animal populations in humanized landscapes. Given their low dispersal capacity, amphibians in the Mediterranean region are threatened by habitat fragmentation and loss due to changes in land use, including agricultural intensification.

Un estudio, con participación del Museo Nacional de Ciencias Naturales (MNCN-CSIC), ha analizado la conectividad entre poblaciones del gallipato, ‘Pleurodeles waltl’, una especie de anfibio catalogada como ‘Casi Amenazada’ por la Unión Internacional para la Conservación de la Naturaleza (UICN) en áreas agrícolas de la provincia de León.
