According to the dispersal models, T. mauritanica will be able to colonise a similar geographic range compared to the one obtained with the correlative models for the future. Finally, the niche overlap results demonstrate that T. mauritanica’s realised niche has not been conserved over space, as the naturalised climatic niche of the introduced populations differs significantly from its native one.

Naturalized quarries can host rich amphibian communities, potentially playing an important role in local and regional population dynamics. Despite their importance for conservation, few studies have evaluated their potential to host large, viable populations and to connect breeding nuclei in neighboring areas, promoting long-term demographic resilience at the regional scale.

Para investigar esto, un numeroso equipo de científicos de España, México, Portugal, Dinamarca, Australia, Sudáfrica y varias universidades canadienses, realizaron pruebas para evaluar el papel de la temperatura como factor limitante para el rango de espacios potenciales de una especie. Compararon los hábitats actuales de 460 tipos de animales de sangre fría con las áreas y temperaturas donde potencialmente podrían residir en función de su tolerancia a la temperatura. Leer más.

This study presents a comprehensive analysis of niche expression at range margins, anticipating a heightened impact of landscape changes in V. latastei. The methodological framework implemented here, and our findings, hold significant relevance for biodiversity management and conservation in human-impacted areas. Leer más.
