Abstract

The subspecies of the Pacific sheath-tailed bat that once occurred throughout the Mariana Islands (Emballonura semicaudata rotensis) has not been well studied biologically, despite its declining status. It is a small insectivorous bat, and in the Mariana Islands it is known to roost only in caves. All available data indicate that it now occurs as a single remnant population on Aguiguan. Overall, the species is categorized as endangered by the International Union for the Conservation of Nature and Natural Resources. The subspecies is protected by law in the Commonwealth of the Northern Mariana Islands (CNMI), and is considered a Category 3 candidate for listing under the U.S. Endangered Species Act...
