Wisconsin watershed program involves high schools to collect, share data
A group of high schoolers in the Green Bay, Wisc. area are learning about careers in environmental science thanks to the Lower Fox River Watershed Monitoring Program . The program, supported by the University of Wisconsin, has involved more than 700 students since its 2003 launch. “We have almost ten years of data,” said Annette Pelegrin, program coordinator. “It began in 2003 with five watersheds. We’ve trained teachers and schools that are interested and showed them how to measure different parameters.” Those include flow, temperature, transparency and turbidity of the program’s streams. YSI 55 meters are used to measure dissolved oxygen and levels of phosphorus, ammonia and nitrogen are checked with a Hach colorimeter.

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.
