Zoologists and wildlife biologists study animals and other wildlife, and how they interact with their ecosystems. They study the physical characteristics of animals, animal behaviors, and the impacts humans have on wildlife and natural habitats.
Zoologists and wildlife biologists perform a variety of scientific tests and experiments. For example, they take blood samples from animals to assess their levels of nutrition, check animals for disease and parasites, and tag animals in order to track them.
Zoologists and wildlife biologists conduct research for a variety of purposes. For example, many zoologists and wildlife biologists work to increase our knowledge and understanding of wildlife species. They also work closely with public officials to develop wildlife management and conservation plans that protect species from threats and help animal populations return to and remain at sustainable levels.
Zoologists and wildlife biologists use geographic information systems (GIS), modeling software, and other computer programs to estimate wildlife populations and track the movements of animals. They also use these computer programs to forecast the spread of invasive species, diseases, changes in the availability of habitat, and other potential threats to wildlife.
Most zoologists and wildlife biologists work on research teams with other scientists and technicians. For example, zoologists and wildlife biologists may work with environmental scientists and hydrologists to monitor the effects of water pollution on fish populations.
