We review the distribution and conservation status of Old World fruit bats (Pteropodidae) in tropical and subtropical China. Our results are based on a series of surveys conducted between 1999 and 2008 by Chinese researchers and international collaborators, spanning almost the entire range of pteropodids within China over nine provinces. Additionally we provide new information on morphometrics and notes on ecology. We also review earlier Chinese literature on fruit bats because much of this has previously been inaccessible to western scientists, and we evaluate the reliability of some of these older records. Thirteen species of fruit bats have been reputed to occur in China, including one species restricted to Taiwan. We classified Chinese fruit bats according to distribution and status as follows: Resident (six species, including one species formerly found in Taiwan and now restricted to its neighbouring islands), Marginal (three species), Questionable (one species) and Alien (three species). Consequently, only five species are encountered with any regularity in mainland China and Hainan Island: Cynopterus sphinx, Eonycteris spelaea, Macroglossus sobrinus, Rousettus leschenaultii, and Sphaerias blanfordi. Three species in the genus Pteropus are referred to in old records, but these bats are clearly not native to mainland China.
The foraging behavior of greater short-nosed fruit bats (Cynopterus sphinx) on wild banana (Musa acuminata) and subsequent dispersal of seeds were studied in the Tropical Rainforest Conservation Area, Xishuangbanna Tropical Botanical Garden, Yunnan province, by direct observation of marked fruits, mist netting, and seed collection. The mean number (± SE) of individual C. sphinx captured by mist net were 2.2 ± 0.33/day and 1.4 ± 0.32/day in the rainy season (September to October) and dry season (November to December), respectively; the difference was not significant. The number of seed pellets expelled was 9.0 ± 1.12/day and 7.2 ± 1.37/day in the rainy and dry seasons respectively; again the difference was not significant. The removal curves for marked fruit were similar for 10 focal trees. Fruits were consumed heavily within two weeks after ripening and all the marked fruit were removed within one month. The difference in seed dispersal was significant between different feeding roosts indicating that patterns of seed dispersal may not be uniform. We found the seeds of M. acuminata can be dispersed by C. sphinx to a distance of about 200 m, and C. sphinx can be considered as an effective seed disperser of M. acuminata.
