05 Jun 2013: First Amphibian Declared Extinct
‘Rediscovered’ in Israel’s Hula Valley

A team of scientists says it has “rediscovered” in northern Israel the first amphibian declared extinct by the International Union for Conservation of Nature (IUCN), a species of frog that turns out to be the only surviving member of an extinct genus of frogs. First discovered in Israel’s Hula Valley in the 1940s,

the Hula painted frog was presumed gone when Hula Lake dried up in the late 1950s, and it was declared extinct in 1996. But since an individual frog was discovered during a patrol in Hula Nature Reserve in 2011, an additional 10 specimens have been found, according to a study published in the journal Nature Communications. And while the frog had originally been categorized as a member of the Discoglossus group of painted frogs, which are found across northern and western Africa, genetic analysis has revealed that the Hula frog is more closely related to a genus of frogs, Latonia, that were common across Europe during prehistoric periods but considered extinct for a million years. “In other words,” the study says, “the Hula painted frog is a living fossil, and therefore calls for special attention to its survival.” The researchers say plans to re-flood parts of the Hula Valley could help restore the frog’s original habitat and ultimately expand its populations.
