The Center for Systematic Biology and Evolution at the Academy of Natural Sciences engages in biodiversity research that "involves the discovery of species and the working out of the relationships among those species, why they are distributed as they are in the world, and their interactions with other species." This website provides information about the collections and research activities of the Center's many departments including Botany, Diatoms, Herpetology, Ichthyology, Mammalogy, Ornithology, Vertebrate Paleontology, and more. A link is provided to the Collections Database, which allows visitors to search a portion of the Academy's extensive biological collections containing over 17 million specimens. The site also links to other sections of the Academy of Natural Sciences website including a Staff Directory; the Scientific Publications Department; available employment opportunities and internships, and information about research opportunities for undergraduate, graduate, and postdoctoral students.
