Mammalogy has extensive historical collections from Central America, Mexico and the southeast, central and western regions of the United States, as well as Alaska. Most of the collection consists of nicely prepared skins, skulls and complete skeletons, with most recent specimens accompanied by tissues. There is broad taxonomic coverage, including important holdings of Central and South American marsupials, insectivores, bats and rodents; Holarctic shrews, microtines and squirrels; and North American bats, insectivores, carnivores, rodents and lagomorphs. Recent additions include outstanding collections from the Philippines and New Guinea. We anticipate continuing to maintain our strengths in these geographic regions, emphasizing bats, rodents, and insectivores. These are our current taxonomic strengths.
