Dr. Karen Lips and her team documented the association of disease and the massive decline of amphibians within a protected national park in El Cope, Panama in 2006 (Lips, K. R., Brem, F., Brenes, R., Reeve, J. D., Alford, R. A., Voyles, J., Carey, C., Livo, L., Pessier, A. P. & Collins, J. P. 2006. Emerging infectious disease and the loss of biodiversity in a Neotropical amphibian community. Proc. Nat. Acad. Sci. 103:3165-3170.). Further findings just published by Andrew Crawford, Karen Lips and Eldredge Bermingham in PNAS have shown through DNA barcoding techniques that although 30 species are known to have disappeared from this study site, nearly a dozen more may have disappeared before they were even described to science!
I ran across this recent press on the subject following the publication of their paper and thought I’d share it: http://www.physorg.com/news198764525.html

Knowing that habitat loss is the number one threat to amphibians and thinking about how many species we KNOW are lost to habitat loss, it makes me think about how these new data may indicate that even more species lost via destruction of their homes is even higher than we know! Not only are species going missing faster than we discover new ones, the rate is much higher than I would have thought.
