We perform multidisciplinary research (evolutionary ecology, behavioral ecology, spatial population ecology, community ecology, demography and population dynamics, extinction patterns, conservation genetics, ecophysiology etc.) aimed at building the scientific basis needed for the conservation of biological diversity in all its forms. Conservation biology is a response by the scientific community to the current biodiversity crisis motivated by human induced global changes that are resulting in an unprecedented extinction episode. Our research is oriented towards the composition, structure and processes within and between ecosystems, communities, species, populations, individuals and genes. Our work is framed by the evolutionary paradigm and by the recognition that ecological dynamics are typical of highly stochastic nonequilibrium complex systems with strong external forcing. In our view, problem solving in Conservation Biology requires using all available information under the current theoretical understanding, and, when needed, the further development of that theory to improve our prediction capacity. We apply multiple techniques within a multidisciplinary context, from molecular genetics to remote sensing, and from modeling to isotopic analyses, using theoretical, experimental and observational approaches. We directly use many of them, additionally seeking for external cooperation in their application both inside and outside the EBD-CSIC. We collaborate with researchers from all over the world. We have no a priori taxonomic or regional bias, though for historical and practical reasons an important part of our work has focused on vertebrates in Doñana Natural Area. We also work all over the Iberian Peninsula, the rest of Europe, Africa, the Neotropical Region and the Antarctica , where most of our interests and social demands are located.
