El Parque Nacional de Doñana está herido de muerte. No hay agua y no hay vida. El 59% de las lagunas se han secado, según los datos de la Estación Biológica del CSIC, y el ecosistema está al borde de entrar en un punto de no retorno que llevaría a la desaparición de una rica red de biodiversidad, sinigual en toda Europa. El diagnóstico, tras años de sobreexplotación del humedal, no es halagüeño: poblaciones de aves en declive, mamíferos que desaparecen, depredadores sin presas y una vegetación cada vez más escasa que no deja oportunidad para el refugio animal.

Results showed that seminatural habitats differed from actual natural habitats in some microhabitat characteristics and in diversity of available prey. The diet of geckos also differed between habitats, being less diverse in altered habitats. However, the health state (body condition) of geckos was similar between habitats. These geckos seem able to modify their diet selection patterns to cope with anthropic disturbances of the habitat, which would allow them to inhabit and prosper in human-altered ecosystems.

We found that the foraging activity of S. perspicillata is positively affected by body size and negatively affected by potential competitor’s activity on the forest floor during the sampling, which also significantly weakened the positive relationship with body size. These results suggest the presence of an interference/interaction occurring between the two species and affecting the foraging activity of S. perspicillata. This competitive interaction is size mediated and configured as interference competition rather than exploitative competition. Leer más.
