Scientists Shine Light On World's Least-Studied Bat

Oct. 29, 2013 — The Mortlock Islands flying fox, a large, breadfruit-eating bat native to a few remote and tiny Pacific islands, has long been regarded as one of the world's least studied bats. For more than 140 years nearly all that scientists knew about this animal was derived from one lonely specimen preserved in a jar of alcohol in the Natural History Museum, London.


Today, in a paper in the open access journal ZooKeys, a team of bat biologists led by Don Buden of the College of Micronesia published a wealth of new information on this "forgotten" species, including the first detailed observations of wild populations.

And it is none too soon, says paper co-author Kristofer Helgen of the Smithsonian's National Museum of Natural History, as the low-lying atolls this bat calls home are likely to be increasingly affected by rising ocean waters brought on by climate change.

"Very little is known about many of the mammals that live on remote Pacific islands, including this beautiful flying fox," Helgen said. "This study gives us our first close look at a remarkable bat."

The lone London specimen was collected in 1870 from the Mortlock Islands, a series of atolls that are part of the Federated States of Micronesia in the west-central Pacific Ocean. British biologist Oldfield Thomas used this specimen to name the species Pteropus phaeocephalus in 1882. But during a recent study of the bat, Buden discovered that a German naturalist voyaging on a Russian expedition had observed and named the animal some 50 years earlier.

Snakes Minus Birds Equals More Spiders for Guam: Ecologists Look for Effects of Bird Loss Caused by Invasive Brown Treesnake

ScienceDaily (Sep. 13, 2012) — In one of the first studies to examine how the loss of forest birds is effecting Guam's island ecosystem, biologists from Rice University, the University of Washington and the University of Guam found that the Pacific island's jungles have as many as 40 times more spiders than are found on nearby islands like Saipan.

"You can't walk through the jungles on Guam without a stick in your hand to knock down the spiderwebs," said Haldre Rogers, a Huxley Fellow in Ecology and Evolutionary Biology at Rice and the lead author of a new study this week in the open-access journal PLOS ONE.

The results are some of the first to examine the indirect impact of the brown treesnake on Guam's ecosystem. The snake, which was accidentally introduced to the island in the 1940s, decimated the island's native bird species in one of the most infamous ecological disasters from an invasive species. By the 1980s, 10 of 12 native bird species had been wiped out, and the last two live only in small areas protected by intense snake-trapping.

17 NEW SPECIES DISCOVERED IN THE PACIFIC ISLANDS

Increased scientific surveys have resulted in the discovery of many fascinating new species. Between the rivers of the Philippines, the rain forests of Papua New Guinea, and the Foja Mountains of Indonesia there have been 17 new species added to the books! This is encouragement for all of us to protect our precious ecosystems and let all the life forms they contain thrive.
