Author:Blumenbach, 1779.
Comments:As is the case for all species in this book, the conservation status for each bat species is reported below based upon listings of the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES), the United States Endangered Species Act (U.S. ESA), and the 2003 International Union for Conservation of Nature and Natural Resources Redlist (here cited "IUCN 2003"). In addition, two IUCN/SSC Action Plans provide more detailed information. The Action Plan for Old World Fruit Bats (Pteropodidae; cited below as "IUCN/SSC Action Plan, 1992", compiled by Mickleburgh et al., 1992) is over a decade old, but provides detailed information on the conservation status of subspecies as well as species of pteropodids, including the status of taxa not thought to be at risk. This publication also summarizes considerable information on ecology and population biology of pteropodids. The conservation status of other families of bats was assessed more recently in the Global Status Survey and Conservation Action Plan for Microchiropteran Bats (cited below as "IUCN/SSC Action Plan, 2001", compiled by Hutson et al., 2001). This work summarized the status of each microchiropteran species recognized by Koopman (1993) as well as some additional species described or revised subsequent to that publication. Threat categories listed in this work are identical to those found in the IUCN 2003 Redlist (which for bats is identical to the 2000 Redlist), but additional regional and taxon-specific conservation status information is included. Although both of the Action Plans were very comprehensive, many of the conservation assessments need to be revised in light of the new classification presented here, which includes 191 species not listed in Koopman (1993). Some of these are new species discovered in the last decade, but many were previously considered to be subspecies of other taxa. The majority of these newly recognized species have restricted geographic ranges, and may therefore be at risk. In addition, many long-recognized species are now believed to have much smaller geographic ranges than previously thought (a result of "taxonomic pruning" of populations now considered to be distinct species). The conservation status of these taxa should also be reevaluated.
