Bat-killing fungus, air patterns and microbeads: this week in environmental news

Every Friday, MNA shares recent environmental news stories from around the state and country. Here’s some of what happened this week in environmental and nature news:

Bat-killing fungus all but invincible, study finds (Mother Nature Network): The fungus, Pseudogymnoascus destructans, causes white-nose syndrome in American bats and is extremely difficult to kill. It has already killed about 6 million American bats in the last seven years and has a mortality rate of nearly 100 percent. The fungus can be found in 22 U.S. states and five Canadian provinces. The fungus most likely came from Europe, where native bats are mostly immune. Scientists are searching for ways to control the spread of the fungus because American bats are important to the economy. Insect-eating bats keep disease-spreading and crop-killing insects in check and save the U.S. agriculture industry around $3 billion per year.

Strange air patterns could help predict heat waves (Mother Nature Network): New research shows that heat waves are usually preceded by a global weather pattern known as a wavenumber-5 pattern. This consists of five high-pressure systems evenly distributed across the Northern Hemisphere. The configuration usually occurs 15 to 20 days before extreme weather in the United States. Because of this, the wavenumber-5 pattern could be used to enable better forecasting, which could save between 600 and 1,300 lives per year.

Nonprofit launches consumer app to help keep microbeads out of the Great Lakes (Journal Sentinel): Microbeads found in hand soaps, facial scrubs and other exfoliating products bypass sewage treatments and ultimately end up polluting the Great Lakes and getting eaten by wildlife. Researchers say there are higher concentrations of microbeads in the Great Lakes than there are in the oceans. Several companies, including L’Oreal, Unilever and Johnson & Johnson, pledged to use natural alternatives to microbeads after the findings were shared. A Netherlands-based foundation has created a free cell phone app called “Beat the Microbead” that allows consumers to scan a product before buying it to figure out if the product contains microbeads and if the company has agreed to remove them or not.

Great Lakes state playing catch-up in effort to build water-based economy (Great Lakes Echo): Milwaukee and Ontario are ahead of Michigan in efforts to turn water-based technology, academic research and tourism into jobs and revenue. The director of the Michigan Economic Center, John Austin, said Michigan has all the assets necessary to support a thriving “blue economy:” plentiful freshwater, a growing tourism industry, research universities focused on water issues and manufacturers to turn concepts into products. Austin said building Michigan’s blue economy begins with cleaning polluted waterways and restoring damaged shorelines.

Endangered Kirtland’s Warbler: Looking good, but what lies ahead (MLive): The Kirtland’s Warbler has much such a drastic turnaround in Michigan that government agencies and non-governmental groups have discussed taking it off the federal Endangered Species list. Michigan holds 98% of the Kirtland’s Warbler population, so it is important to assure the birds have ongoing support once they come off the list. Continued human intervention is the key to the warbler’s success. It is also important to limit the population of cowbirds, who lay their eggs in warbler nests and compete for food.
