Philipp Franz von Siebold (1796–1866) was one of the earliest European naturalists to live in Japan. Through most of the nineteenth century, however, until the 1860s, movement of foreigners within Japan was severely restricted, impairing Siebold's ability to observe wildlife in the countryside or collect zoological specimens. Among the Japanese mammals that Siebold was able to see, if not necessarily in the wild, and acquire examples of, was Pteropus dasymallus, the Ryukyu Flying Fox. On the basis of Siebold's early work, Coenraad Jacob Temminck (1778–1858), in 1825, first described the species scientifically. Siebold's initial observations on the fruit bat's range, however, proved to be incorrect. His notes on the species' distribution in and around Nagasaki in southern Kyushu and Tokyo in central Honshu were particularly contradictory, apparently based, at least in part, upon an initial confusion with either Pteromys petaurista (Japanese Giant Flying Squirrel) or Pteromys momonga (Japanese Dwarf Flying Squirrel).

AbstractSmall isolated populations are vulnerable to both stochastic events and the negative consequences of genetic drift. For threatened species, the genetic management of such populations has therefore become a crucial aspect of conservation. Flying foxes (Pteropus spp, Chiroptera) are keystone species with essential roles in pollination and seed dispersal in tropical and subtropical ecosystems. Yet many flying fox species are also of conservation concern, having experienced dramatic population declines driven by habitat loss and hunting. The Ryukyu flying fox (Pteropus dasymallus) ranges from Japan and Taiwan to the northern Philippines, and has undergone precipitous population crashes on several islands in recent decades. To assess population genetic structure and diversity in P. dasymallus, and its likely causes, we analyzed mitochondrial and microsatellite DNA. Both markers showed significant genetic differentiation among most island populations with patterns of isolation-by-distance. However, while mitochondrial haplotypes showed some mixing across the region, likely reflecting historical colonization and/or dispersal events, microsatellites markers showed clear subdivisions corresponding to the position of deep ocean trenches. The current distribution of P. dasymallus and its subspecific diversity therefore appears to have arisen through vicariance coupled with a long history of restricted gene flow across oceanic barriers. We conclude that isolated island subgroups should be managed separately, with efforts directed at reducing further declines.
