Our results demonstrate that vegetation structure variables derived from automated image processing significantly relate to viper microhabitat selection. Our method minimizes the risk of subjectivity in measuring vegetation structure, enables the aggregation of adjacent pixel data and is suitable for comparison of or extrapolation across different vegetation types or ecosystems.

The mechanisms underlying the effects of location on distances between captures remain to be identified, but may be related to foraging for abundant prey items on the wrack line. Our study confirms the remarkable terrestrial site fidelity in P. cultripes, which might be detrimental to coastal populations if localized perturbations affect coastal environments. Leer más.
Usually when you ask someone what their favourite animal is, the answer is typically either some kind of mammal or reptile. Of course, there is nothing wrong with that as there are many amazing species all over the world. Leer más.
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.
