Reptiles Mysteriously Declining Alongside Amphibians

The catastrophic declines in frog and salamander populations may be spreading to reptiles. New Scientist reports that scientists reviewed data on ground-dwelling reptiles and amphibians collected over the past 35 years at La Selva Biological Station in Costa Rica, finding a 75-percent decline in both reptiles and amphibians in native forest since 1970. The numbers of both increased in abandoned cacao plantations, by 4% annually for amphibians, and 2.7% per year for reptiles. Fungal diseases or pesticide contamination, blamed for amphibians’ decline elsewhere, are unlikely to be behind the declines at La Selva, since they would affect abandoned plantations as well as native forest. The researchers suggest the cause may be a warmer, wetter climate that stunts tree growth, and reduces the leaf litter, where reptiles and amphibians live. —Julia Whitty

WE'RE TAKING A SHORT BREAK…

from the big banner at the top of our pages asking for the donations that make Mother Jones' nonprofit journalism possible. But we still have upwards of $300,000 to raise by June 30, whether we get there is going to come down to the wire, and we can't afford to come up short.

If you value the reporting you get from Mother Jones and you can right now, please join your fellow readers who pitch in from time to time to keep our democracy-advancing, justice-seeking journalism charging hard (and to help us avoid a real budget crunch as June 30 approaches and our fiscal year ends).
