Mammalogy is the field of biology that specializes in the study of mammals. It involves understanding the anatomical features, behavior, ecology, and evolutionary history of mammals, as well as their interactions with their environment and other organisms. Mammalogists use a variety of techniques to study mammals, including field observations, lab experiments, and molecular genetics. The knowledge gained from mammalogy has important applications in conservation efforts, as many mammal species worldwide are threatened with extinction due to habitat loss, hunting, and climate change.
