Two weeks ago, the last known Rabbs’ fringe-limbed tree frog died in a biosecure safehouse at the Atlanta Botanical Garden. Its distinctive, barklike call was last heard in the wild, as far as we know, in a Panamanian forest in 2007.

I was among a group of biologists who discovered this species in 2005 in the canopy of a cloud forest in central Panama. We documented a remarkable behavior never seen in any other animal. The males stayed with their tadpoles in small water-filled cavities high in the trees. These tiny arboreal ponds lacked sufficient food for the tadpoles, so the male would lower himself into the water, allowing his offspring to rasp the skin from his back for nutrition.…  Seguir leyendo »

Stopping the Next Amphibian Apocalypse

For the past 25 years we have watched helplessly as a wide range of amphibians around the world have died from a pathogenic fungus, known as Bd (Batrachochytrium dendrobatidis). Now, yet another fungal contagion appears to have been unleashed. This one is spreading among salamanders in parts of Europe and threatens devastation.

This new menace, known as Bs (Batrachochytrium salamandrivorans), appears to have invaded Europe from Asia by way of the pet trade. In Asia, salamanders carry the infection but don’t become sick from it. But European salamanders are particularly susceptible to its pathogenic effects. The mortality rate is 96 percent.…  Seguir leyendo »
