Arctic contaminants threaten polar bears

Polar bears looking for food on the sea ice in Baffin Bay north of Clyde River may find seals to eat, but the seals will likely be loaded with the industrial poisons and pesticides still found in the Arctic air and water.

Living at the top of the food chain holds unseen dangers for polar bears, because they absorb toxic substances, like pesticides and flame retardants, through their diet of seals.

These man-made pollutants originate far to the south, where they’re used in agriculture and industry, even though they can lead to diseases like cancer and birth defects in humans and wildlife.

Disease kills 900 birds on Marsh Lake in western Minn.

The Minnesota Department of Natural Resources is blaming a large bird die-off in western Minnesota on Newcastle disease, a viral disease that commonly infects cormorants.

As of earlier this week, about 500 cormorants and 400 ring-billed gulls had been found dead on Marsh Lake near Appleton in Big Stone County.

Erika Butler, a wildlife veterinarian for the Minnesota DNR, said the birds died from what's known as Newcastle Disease, which causes partial or complete paralysis in water fowl.

White nose syndrome, bats - USA (15) - Archive Number 20100808.2712

There has been a great deal of discussion of possible in-situ treatments for bats affected by WNS among those most actively studying it.

Unfortunately, hibernating bats may or may not have the environmental cues or physical ability to feed in the caves where they hibernate.

They are finely tuned to spend a portion of their lives in torpor; they simply may not have faced a challenge of this type so as to develop a winter feeding strategy.
