Juan José Negro received his degree in Biology at the University of Seville in 1987, and his Ph.D. in 1991. After that, he moved to Montreal, Canada, where he worked as a postdoc for three years at McGill University. His research addresses questions on evolutionary ecology and conservation biology. His model species are generally birds of prey, a group of species with small population sizes and permanent conflicts with human activities. He has also worked with other avian species, either threatened with extinction, such as the white-headed duck, or species of social or economic interest, including the red-legged partridge and the greylag goose. He keeps two research lines seemingly unrelated. On the one hand, he applies molecular tools to deal with ecological questions affecting individuals and populations. On the other hand, he carries out research on the evolution of bird plumage coloration and its role in signaling genetic quality, social status, and body condition. He is also interested in the application of new technologies to monitor wildlife populations. He currently leads a project aimed at demonstrating the applicability of light UAVs for wildlife research.
