Deadly virus hits turtles, tadpoles in Montgomery County
Katherine Shaver ― Washington Post

Maryland biologists study­ing box turtles rescued from the bulldozers on the Intercounty Connector construction site have made a grisly find: An alarming number of the tiny turtles later died, and biologists say their demise appears to be unrelated to the highway.

Worse yet, the cause of their death — an animal disease called ranavirus taking root across the United States — also is believed to have killed nearly every tadpole and young salamander in the study area in Montgomery County’s North Branch Stream Valley Park since spring 2010.

The discoveries have alarmed state wildlife officials and biologists, who worry about how far ranavirus has spread, how widely it has affected the ecosystem, and how it apparently jumped between turtles — which are reptiles — and amphibians. If the virus spreads or goes unchecked for long, wildlife experts say, it could devastate some local populations of box turtles, frogs and salamanders. That loss, biologists say, would ripple along the food chain to other animals.
