Basic studies on the ecology of organisms in biosphere reserves.

Dr. Alfredo Ortega Rubio

MAIN CONTRIBUTIONS:

All these studies share the comnon goal of to contribute to the knowledge of the ecology of ecosystem key species. In this framework we have contributed to the knowledge of very important aspects of endangereed species, such as the Peninsular Pronghorn and the Peregrine Falcon. Also, we have studied ecological aspects of endangered plants such has the Walking cactus and Behria.

Finally, we have also contributed to deepen the knowledge of the ecology of key species in the structuration and functioning of desert, forest and insular ecosystems, such as the lizards and the crabs.
