TRANSCRIPT

From the Cumberland Gap to the Atlantic Ocean, this is Virginia Water Radio for the week of March 16, 2015.

This week, we drop in on a Virginia social gathering during a highly competitive round of “Name Your Favorite Amphibian with a Tail.”  Sound too good to be true?  Well, just have a listen for about 25 seconds. 


VOICES


Those were the names of 13 species of salamanders, out of over fifty species in Virginia and several hundred species worldwide.  As the names indicate, salamanders show a variety of regional locations, habitat preferences, and characteristics.  Salamanders occur all across Virginia, but the western areas of Virginia and other Southern Appalachian states are considered globally significant for their diversity of salamanders, as well as various other organisms.  Salamanders are tailed members of the scientific class called amphibians; frogs and toads are amphibians whose adults don’t have a tail.  Many salamander species follow the typical amphibian life-cycle pattern of living on land as adults but having an aquatic larval stage.  Some salamanders, however, are completely aquatic, while others are completely land-based.  Even on land, salamanders require moist conditions to avoid drying out through their skin.  Whether in forests, water bodies, or wetlands, salamanders are important components in food webs and other natural cycles, and their presence or absence helps indicate the ecological quality of land and water habitats.

And besides being important ecologically, salamanders have some fascinating symbolic roles in human culture.  Examples include the inspiration for the political term “gerrymander”; names for several musical groups; crime-scene clues in The Salamander, a 1973 novel by Morris West; and the name of the Salamander Resort & Spa in Middleburg, Va., based in part on the World War II experiences of a former owner if the estate.  That owner’s code name was “The Salamander,” because his ability to elude capture recalled the mythology—and word origin—of salamanders being able to survive fire.  Thanks to friends in Blacksburg for calling out salamander names, and they get the last word for a diverse, ecologically important, and somewhat mythical group of animals.

If you’re interested in amphibians and particularly in frog calls, you might want to consider volunteering for the Virginia Frog and Toad Calling Survey, coordinated by the Virginia Department of Game and Inland Fisheries.  See information online at http://www.dgif.virginia.gov/wildlife/frogsurvey/, or contact the department at (804) 367-1000.  The Virginia program is part of the North American Amphibian Monitoring Program.  These programs use the sensitivity of amphibians to water availability and quality as a tool for assessing changes or threats to aquatic systems.
