Photo in the News: "Nonexistent" Flying Fox Discovered


This unusual species of flying fox was recently discovered in the Philippines not long after it was deemed not to exist.
Jake Esselstyn, a biologist with the University of Kansas, was among a team of researchers that found the animal, a type of fruit bat, last year while surveying forest life on the island of Mindoro (see Philippines map).
"When we first arrived on Mindoro, a local resident that we hired as a guide described the bat to me in great detail, and he asked me what it was called," Esselstyn said.
"I politely told him that there was no such bat. I was wrong."
Several days into the survey, the scientists accidentally captured a creature in a net that fit the guide's description: a large flying fox with bright orange fur and distinctive white stripes across its brow and jaw.
"Our guide's description of the animal was quite accurate, and I had to apologize for not believing him," Esselstyn said, adding that the animal is now known as the Mindoro stripe-faced fruit bat.
In his own defense, the scientist pointed out that the species' closest known relative lives some 750 miles (1,200 kilometers) away on an island in Indonesia.
"It makes you wonder if there are other related species on islands between [the two]," he said.
"It also makes you realize how there are probably many more species which have yet to be discovered—in the Philippines and elsewhere," Esselstyn added.
"This discovery emphasizes the need for a great deal more basic biodiversity inventory research."

An iceberg melts off Ammassalik Island in Eastern Greenland -photo

An iceberg melts off Ammassalik Island in Eastern Greenland in this July 19, 2007 file photo. Arctic ice has shrunk to the lowest level on record, new satellite images show, raising the possibility that the Northwest Passage that eluded famous explorers will become an open shipping lane. The European Space Agency said nearly 200 satellite photos taken together in Sept. 2007 showed an ice-free passage along northern Canada, Alaska and Greenland, and ice retreating to its lowest level since such images were first taken in 1978.

Satellites witness lowest Arctic ice coverage in history


Envisat ASAR mosaic of the Arctic Ocean for early September 2007, clearly showing the most direct route of the Northwest Pssage open (orange line) and the Northeast passage only partially blocked (blue line). The dark gray colour represents the ice-free areas, while green represents areas with sea ice. Credits: ESAThe area covered by sea ice in the Arctic has shrunk to its lowest level this week since satellite measurements began nearly 30 years ago, opening up the Northwest Passage – a long-sought short cut between Europe and Asia that has been historically impassable.In the mosaic image above, created from nearly 200 images acquired in early September 2007 by the Advanced Synthetic Aperture Radar (ASAR) instrument aboard ESA's Envisat satellite, the dark gray colour represents the ice-free areas while green represents areas with sea ice.
