Great Lakes lake trout predict global pollutants

When one thinks of iconic fish, Lake Ontario’s lake trout probably don’t come to mind.

But the white-bellied natives of these deep, cold transnational waters have a unique reputation — one considerably nobler than taking bait or adorning plates: They are a barometer for global pollutants.

Michigan tribe battles global corporation

Ten years ago, when an international mining company arrived near the shores of Lake Superior to burrow a mile under the Earth and pull metals out of ore, the Keweenaw Bay Indian Community had to stand for its rights and its water.

Scientists, orphan beetles and a brand new Wisconsin species

Most people do not get excited about little brown beetles — especially those that don’t bite, cause disease or have economic value. But a researcher that has dedicated his life to finding “orphan beetles” has discovered a previously unidentified beetle species endemic to two Wisconsin counties. The findings are in the March issue of The Coleopterists Bulletin. Darren Pollock, a professor at Eastern New Mexico University’s department of biology, examined dead beetles (three male and six female) that were housed at the University of Wisconsin Insect Research Collection and the Carnegie Museum of Natural History. As an expert on little brown beetles, or LBB’s as he calls them, he saw something right away.

Mild winter, early runoff spur swirling sediment in Lake Erie

A mild winter left Lake Erie nearly ice-free. On the first day of spring last week, a NASA satellite snapped a picture of the southern Great Lakes region and showed sediment clouding up the shallow lake. The colors in the image are accurate. The tan colored-water swirling around the shoreline is sediment rushing in from streams and rivers. The warm winter brought more rainfall than snow, so there was increased runoff.
