Scientists are concerned about a world-wide decline in amphibian
populations. But one scientist has been bringing a frog back to its
native habitat. The Great Lakes Radio Consortium’s Lester Graham reports
the Wood frog is once again thriving in an area where it was pushed out
more than 75 years ago:

U-V Light May Be Viral Catalyst

Ultraviolet light, which some scientists say may be the culprit behind

investigation into a smaller but equally important part of the
environmental web. Scientists in Duluth are looking into the viruses
that infect bacteria in the Great Lakes, and how increasing amounts of
U-V light might affect that relationship. The Great Lakes Radio
Consortium’s Stephanie Hemphill reports:
