Chloride Contamination Threatens Thousands of Northeast & Midwest Lakes

Thousands of lakes in the northeastern United States are at risk of chloride contamination. In a 17-state area from Minnesota to Missouri to Maine, elevated chloride levels in some of the region’s nearly 50,000 lakes are driven largely by landscape features that are cleared of snow and ice by road salt in the winter. “The biggest driver of increasing chloride concentrations in these lakes was road density and development. The more developed a watershed, the more likely you are to have roads and parking lots,” said Hilary Dugan, an assistant professor in the Center for Limnology at University of Wisconsin—Madison. Dugan is the lead author on a study examining the issue recently published in Environmental Science and Technology .

Is eradicating Great Lakes sea lamprey an “impossible dream?” Researchers say no

The sea lamprey’s days in the Great Lakes could be numbered. That’s according to one researcher who took one of the first scientific looks at the possibility of sea lamprey eradication in the Great Lakes. So, can you remove enough sea lamprey to make them disappear? “Well the answer is we already have,” said Michael Jones, emeritus professor of fisheries and wildlife at Michigan State University. “Then there’s the obvious question: Why are they still here?”  While multiple gaps in current management techniques, like sea lamprey poisons called lampricides, could account for sea lamprey’s persistence in the Great Lakes, new technology could help sea lamprey managers eliminate inaccessible populations.

America’s Elusive Crayfish and the eDNA that’s Finding Them

The Shasta crayfish and signal crayfish are two similar looking arthropods on two very different ecological trajectories. As one spreads in abundance, originating in the Pacific Northwest and spreading throughout the world, the other has been reduced to a handful of remaining populations spread throughout one river and its tributaries.  Pacifastacus leniusculus - the signal crayfish - has met few obstacles in its widely successful expansion from the Pacific Northwest southward in California and Nevada, as well as Europe and Japan. By some expert accounts, it has reached invader status. And while invasive species are rarely good for the surrounding food webs, it’s Pacifastacus fortis - the Shasta crayfish - that’s suffered the most at the signal crayfish’s fortune.
