The IZW is doing research work in Evolutionary Biology and Ecology, Wildlife Diseases and Reproduction Biology. The experts are analysing mammals and birds in their interaction with people and biotic and abiotic environment (biotope, nutrition, pathogens and predator-prey relationship).

Main aim is research on adaption activities and limits of greater wild life and their role in semi-natural and semi-cultural ecosystems. Main focused regions are Central Europe, East Asia, East and South Africa. The IZW attaches grate importance to the interdisciplinary work of biologists and veterinarian. The research aims of the IZW are achieved by cooperation projects with sanctuaries and zoos in Europe, Asia, Africa and North America.

The IZW belongs to the Forschungsverbund Berlin and counts about 150 staff members, the annual budget of the IZW is about 7,1 million EUR. The Forschungsverbund Berlin (FVB) pools eight natural-, environmental-, and life science- orientated institutions which are scientific independent but intend interests in an incorporated enterprise. All institutes of the FVB belongs to the Leibniz-Gemeinschaft.
