Florida manatees die in record numbers this year

A report on fish and wildlife said that last winter’s frigid winter killed a record 699 manatees in Florida.

According to the Florida Fish and Wildlife Conservation Commission’s Research Institute, a record number of Florida manatees died in 2010 from unusually cold weather.

Typically, most manatee deaths are caused by collision with power boats. A new survey reveals that there are only 5,000 manatees left in Florida.

Tattered Wings: Bats Grounded by White-Nose Syndrome’s Lethal Effects on Life-Support Functions of Wings

Damage to bat wings from the fungus associated with white-nose syndrome (WNS) may cause catastrophic imbalance in life-support processes, according to newly published research

This imbalance may be to blame for the more than 1 million deaths of bats due to WNS thus far, proposes Carol Meteyer, a pathologist with the U.S. Geological Survey’s National Wildlife Health Center and a lead author of the research published in BMC Biology.

Physiological problems caused by the novel fungus, may, in fact, represent a completely new disease paradigm for mammals, Meteyer and her colleagues wrote.

"Super-toxic" rat poisons kill owls, other wildlife

Owls are dying under gruesome circumstances, bleeding to death from stomach hemorrhages in an agonizing and days-long decline.

The culprit: An extra-potent class of rodenticides that has flooded the market in recent decades.

Six of 164 dead barn owls, barred owls and great horned owls in a western Canada study had pesticide levels high enough to kill them outright, while readings in up to 30 percent of the others appeared toxic and seemed likely to handicap owls.

Reported Wildlife Mortality Events to the USGS National Wildlife Health Center Updated

USGS and a network of partners across the country work on documenting wildlife mortality events in order to provide timely and accurate information on locations, species and causes of death. This information was updated on December 14, 2010 on the USGS National Wildlife Health Center web page, New and Ongoing Wildlife Mortality Events Nationwide.
