A new study finds that frogs, toads, salamanders and other amphibians in the U.S. are dying off so quickly that they could disappear from half of their habitats in the next 20 years. For some of the more endangered species, they could lose half of their habitats in as little as six years. The nine-year [...]

Frog-Killing Chytrid Fungus Hits Rarely Seen, Wormlike Amphibians

caecilian

Don’t feel bad if you’ve never seen a caecilian, let alone don’t know how to pronounce the word. These rare, legless amphibians—which look like a cross between a worm and a snake—spend most of their time underground, far from the prying eyes of scientists and other humans. Although some of the 190 or so known [...]

Leopards, Tortoises, Harlequin Frogs and other Links from the Brink

amur leopard

Last year I wrote somewhere around 150 articles about endangered species. I could have easily written closer to 1,000. One blog simply can’t cover all of threatened species around the world, as hard as I try. But I hate letting news items (not to mention species) fall through the cracks. And so, here is the [...]

Once Extinct in the Wild, Kihansi Spray Toad Returns to Tanzania (by Way of the Bronx and Toledo)

Kihansi Spray Toad

Two American zoos have helped to save an African amphibian from extinction. The Kihansi spray toad (Nectophrynoides asperginis) was declared extinct in the wild in 2009 after its only habitat, the waterfalls of Kihansi Gorge in Tanzania, dried up following the establishment of a nearby hydroelectric dam. But this month 2,000 toads returned to Kihansi, [...]

The frog-killing fungus Batrachochytrium dendrobatidis (Bd), which causes the disease chytridiomycosis, has been blamed for about 100 amphibian extinctions around the globe since it was first observed in 1998, but clear information on exactly how it spreads has remained a mystery. Now a team of scientists working in Belgium have come up with one potential [...]

Extinction Looms for Rare Frog Species, Now Down to 1 Individual

And then there was one. The last known Rabb’s fringe-limbed tree frog (Ecnomiohyla rabborum) now lives by himself at Zoo Atlanta in Georgia after the zoo euthanized the only other member of its species.

Last week, Santa Cruz County Board of Supervisors Chairman Mark W. Stone sent a letter to the board urging it to enact a ban in 2012. Stone’s request followed [...]

Hellbender Salamander Gets Endangered Species Designation, but No Habitat Protection—and That May Be a Good Thing

The U.S. Fish and Wildlife Service (FWS) this week granted the Ozark hellbender (Cryptobranchus alleganiensis bishopi) protection under the Endangered Species Act (ESA) but made the unusual decision not to declare critical habitat for the rare, giant salamanders because, it said, doing so could open it to threats from those who would illegally collect the [...]
