Study: Bat-killing Disease Will Wipe Out Indiana Bats in Much of Current Range

A new scientific study predicts that the beleaguered Indiana bat, an endangered species hit hard by a new deadly disease called white-nose syndrome, will virtually disappear within about 10 years from large portions of its range. The U.S. Geological Survey study forecasts that more than 90 percent of the total Indiana bat population, which ranges from New England to the Ozarks with its stronghold in the Midwest, will be exposed to the fungal disease within the next two decades.

If the species can develop immunity to the disease, which has not yet been documented for Indiana bats, there eventually may be recovery in more northern parts of the original range. However, other areas may lose Indiana bats permanently.

Higher numbers of CWD-infected deer in Iowa County worry wildlife researchers

An uptick in deer with Chronic Wasting Disease (CWD) in Iowa County has caught the attention of wildlife researchers in Wisconsin.

The annual infection rate in northern Iowa County has grown 27 percent for all deer two and a half years old or older, and the disease rate for adult bucks is doubling every two to three years. Department of Natural Resources (DNR) wildlife manager Eric Lubner says the agency is trying to determine if this is a coincidental spike in numbers or a definitive trend.

The Impact of the Nation’s Most Widely Used Insecticides on Birds

A new report commissioned by the American Bird Conservancy (ABC) has assessed commonly used neonicotinoid insecticides to be lethal to songbirds. These insecticides were introduced in the early 1990′s to replace organophosphates and other chemicals that were known to have toxic affects on wildlife and ecosystems. Today neonicotinoids are the worlds most widely used insecticides.

Recent findings have implicated neonicotinoids in the decline of bee populations which has led to some countries suspending their use.
