Managing Chronic Wasting Disease

The National Veterinary Services Laboratory in Ames, Iowa, has confirmed that a deer harvested by a hunter in November 2010 near Pine Island in southeastern Minnesota had Chronic Wasting Disease (CWD), which is fatal to deer, elk and moose but not known to affect humans or cattle.

The diagnosis, which was confirmed Jan. 25, marks the first time CWD has been found in Minnesota's wild deer herd.

The disease is a serious concern, not only because of the obvious harmful effects on cervid health, but also due to the negative impacts to landowners, hunters and businesses.

Mercury in Bay Area Fish a Legacy of California Mining

Mercury contamination, a worldwide environmental problem, has been called "public enemy No. 1" in California's San Francisco Bay.

Mercury mining and gold recovery in the mid-1800s to late 1900s, combined with present day oil refineries, chemical manufacturing plants and wastewater treatment plants have contributed enough mercury to threaten wildlife and prompt a fish consumption advisory in the Bay Area.

With so many possible sources of contamination, environmental scientists and regulatory agencies would like to know which specific sources contribute most to harmful levels of mercury in the aquatic food web.
