TRANSCRIPT
From the Cumberland Gap to the Atlantic Ocean, this is Virginia Water Radio for the week of April 6, 2015.
SOUNDS ~ 3 sec
This week, those crickets, katydids, and Screech Owl calls open a series of mystery sounds to get you thinking about millions—of living species, that is. Have a listen for about 25 seconds to a few more, and see if you know the word used for the Earth’s huge variety of life, from backyards to the whole biosphere.
SOUNDS ~ 25 sec
If you guessed, biodiversity, you’re right! “Biodiversity” refers to the variety of living species and the ecosystems that support those species, estimated to be in the millions and including what you heard: gnats, frogs, a rattlesnake, an alligator, shorebirds, and a beaver slapping its tail. Scientists consider adequate biodiversity to be crucial for healthy and sustainable natural systems and for those systems’ capacity to provide humans with food, clean air and water, medicines, and many other benefits and services. So all humans have good reasons to care about biodiversity, and Virginia—like most states—has some special reasons. One is that the Commonwealth is part of the Southern Appalachian region—stretching from West Virginia and southwestern Virginia to northern Alabama—which is known for its high biodiversity, including aquatic organisms. For example, the Upper Tennessee River basin, including the Clinch and Holston river watersheds in Virginia, is known particularly for its diversity of fish and mussels.
On the other side of the state, biodiversity is an important
factor in the overall health of the Chesapeake
Bay and Virginia’s other coastal environments. And throughout Virginia, 63 natural area
preserves include significant and often rare examples of species and
habitats. [Source: Virginia Department
of Conservation and Recreation/Natural Heritage Program, http://www.dcr.virginia.gov/natural-heritage/natural-area-preserves/.
5/16/17] In any location, biodiversity
is connected to biology, geology, climate, topography, time, and human
activity, past and present.
MUSIC ~20 sec
