APROTELES BULMERAE AND CAVE BAT CONSERVATION PROGRAM IN PAPUA NEW GUINEA Project Leaders: Dr Debra Wright, Wildlife Conservation Society’s Papua New Guinea Country Program Period: 2006. Funding Partners: Lubee Bat Conservancy, Wildlife Conservation Society, the Rufford Foundation, and the Darwin Initiative.
Because flying foxes are relatively large vertebrates living in conspicuous communal roosts, they are particularly attractive as an easy source of protein to subsistence hunters. In Papua New Guinea cave entrances are partially blocked and all of the emerging bats are killed; this is a severe problem with entire populations being killed in a few days. With student support from Lubee, Kore Tau ( supervisied by Silvia Lomoscola and Debra Wright), spent a total of seven months in the rugged mountains of the Crater Mountain Wildlife Management Area from March 2005 through March 2006. She counted bats in each of 14 caves and sinkholes, mist-netted them for identification and reproductive information, and measured cave parameters to see if any affect bat selection for roosting caves. She also conducted awareness with local hunters on the importance of flying foxes for their forest ecosystems. In doing this work, Kore confirmed the existence of the critically endangered Aproteles bulmerae at two sites, mist-netting eight individuals. Aproteles bulmerae was thought to exist in only one cave in the far west of PNG, until recent indications showed that it also lives in the Crater Mountain area; Kore has now confirmed this beyond doubt. She plans to continue her work with more surveys in Sandaun Province.
AMERICAN SAMOA
NUTRITIONAL ECOLOGY OF THE TONGAN FRUIT BAT (PTEROPUS TONGANUS) Project Leaders: Graduate Researcher Suzanne L. Nelson, Thomas H. Kunz and Stephen R. Humphrey Period: 1998-2002 Lubee graduate fellowship to University of Florida Foundation/Dept of Wildlife Ecology and Conservation.
Bats are one of the only other mammals besides humans that have problems with calcium deficiency, and reproduction by female bats may be limited by their intake of calcium. Bat pups are considered “expensive” to female bats because pups nurse until they are 95% of adult skeletal size and during that time the female provides their total nutrition through extended lactation. To meet the demands of extended lactation, female bats donate their own skeletal calcium to build the skeletons of their pups. The heavy demands of raising several pups can result in female’s bones becoming less dense, similar to osteoporosis in humans, which results in an increased risk of wing-bone fractures. Wing-bone fractures and tooth loss can impede the ability to forage and may affect longevity, fitness, and overall health of the bat.
Lubee funded PhD researcher Suzanne Nelson to test the “calcium-constraint hypothesis” which proposes that reproductive females were more constrained by calcium than energy in their diet. The research utilized wild-caught Tongan fruit bats, fitting bats with radio-collars and monitoring their activities to determine if they were feeding in calcium-rich habitat or calcium-poor habitats across the island, and involved feeding trials with captive bats. Bats preferred high sugar content fruits .
PACIFIC ISLANDS
PACIFIC ISLAND FLYING FOX CONFERENCE Project leaders: BCI/USFWS Period: Honolulu, Hawaii on February 1-2, 1990.
Representatives from 14 island nations and states, and places as distant as Sweden and Scotland, came together for an international meeting on the conservation of Pacific island flying foxes. Designed to help people from the islands secure a better future for their bats and rain forests, the Pacific Island Flying Fox Conference was hosted by Bat Conservation International, and funded by a $100,000 grant from Lubee. Through the conference, wildlife managers from the islands were able to meet with scientists and leading conservationists for discussions about problems facing Pacific island bats. For the first time, many representatives learned how important flying foxes were to their island ecology and in some cases, to their economies as well.
