Danilo Russo is an animal ecologist mainly working on vertebrates (especially bats and more recently rodents) but also on a flagship long-horned beetle, the Rosalia longicorn (Rosalia alpina). His research interests cover a range of topics, including habitat selection, resource partitioning, sensory ecology, social behaviour, evolutionary biology, biogeography and conservation biology. He is currently leading Wildlife Research Unit at University of Naples Federico II.
