Mammalogy's research focuses on New World species, especially those residing in the tropics.  Curator Robert Timm has interests in bats and also in host/parasite relationships, but also works on mammalian ecology and conservation.  Other interests of the division are: disease ecology of mammals of the Great Plains and Rocky Mountains, historical biogeography and evolution of Southeast Asian bats and insectivores, and phylogeography of Pacific Northwest mammals.
