Andrew Crawford and his colleagues discovered 11 new species of amphibians in Panama. But they wish it hadn't happened this way. The team just completed a long-term study of amphibians in Panama's Omar Torrijos National Park, published in the Proceedings of the National Academy of Sciences, showing the startling disappearance of species there. Co-author Karen Lips began the study back before the disease chytridiomycosis, which is caused by a fungus called Batrachochytrium dendrobatidis and has devastated amphibian populations, reached that place and began to afflict its inhabitants.
The pre-decline surveys identified 63 species of amphibians within just a 1.5-square-mile (4-square-kilometer) area. After 2004, 25 of those species had disappeared from the site. As of 2008, none had reappeared. An additional nine species saw an 85 percent to 99 percent decline in their abundance [MSNBC].
