Researchers discover elusive frog

SYDNEY: A tiny, light brown frog species that was thought by many experts to be extinct has been rediscovered alive and well in a remote area of Australia’s tropical north, researchers said on Thursday.

The 40 mm-long Armoured Mistfrog had not been seen since 1991, and many experts assumed it had been wiped out by a devastating fungus that struck northern Queensland State.

But two months ago, a doctoral student at James Cook University in Townsville conducting research on another frog species in Queensland stumbled across what appeared to be several Armoured Mistfrogs in a creek, said Professor Ross Alford, head of a research team on threatened frogs at the university.

Conrad Hoskin, a researcher at The Australian National University in Canberra who has been studying the evolutionary biology of north Queensland frogs for the past 10 years, conducted DNA tests on tissue samples from the frogs and determined they were the elusive Armoured Mistfrog.

Professor Alford’s group got the results on Wednesday. A spokeswoman for the Queensland Environmental Protection Agency also confirmed the findings.

“A lot of us were starting to believe it had gone extinct, so to discover it now is amazing,” Mr. Hoskin said. “It means some of the other species that are missing could potentially just be hidden away along some of the streams up there.”

Craig Franklin, a Professor of Zoology at The University of Queensland who studies frogs, said the Mistfrog’s rediscovery was exciting. “It’s very significant,” he said. “We’ve lost so many frog species in Australia... Hopefully it’s a population that’s making a comeback.”

The chytrid fungus was wildly blamed for decimating frog populations worldwide, including seven species in Queensland tropics between the late 1980s and early 1990s. — AP
