Extinct frog rediscovered in Israel

Mongabay News (California, USA) November 21st, 2011 03:53 PM: Extinct frog rediscovered in Israel

After its marshland was drained, researchers thought the Hula painted frog (Discoglossus nigriventer) had vanished for good. However a patrol at the Ha-Hula lake in Israel recently discovered a single female amphibian that turned out to be the long-lost, and long-sought, Hula painted frog.

"The species now has another chance to survive," Israel's Nature and Parks Authority said last week. However, this is only the sixth specimen ever collected of the Hula painted frog, and its likely the species remains highly endangered.

Not recorded since 1955, the Hula painted frog vanished after 95 percent of its wetland habitat was drained to fight malaria and grow crops. The draining also led to the extinction of the ray-finned fish (Acanthobrama hulensis) and the cichlid fish (Tristramella intermedia).

The Hula painted frog was listed by Conservation International as #9 in the Top Ten Lost Frogs—a list of species researchers hoped most to find during a global search last year to determine the status of 100 missing amphibians. With the rediscovery of the Hula painted frog, two of the top ten have been rediscovered.

Amphibians worldwide are currently undergoing an extinction crisis. While amphibians struggle to survive against habitat loss, climate change, pollution, and overexploitation, they are also being wiped out by a fungal disease known as chytridiomycosis. Currently experts estimate that over 40 percent of the world's amphibians are threatened with extinction, and well over a hundred species have vanished in the last three decades alone.
