Great Lakes Scientist says, “If We Lose The EPA, We Lose Lake Erie”

At the 8th Binational Meeting of the Lake Erie Millennium Network, 125 scientists gathered at the University of Windsor in Ontario to hear experts weigh-in on the health of the southernmost, warmest and shallowest of the Great Lakes.

They presented research on everything from climate change, water quality, phosphorous, agricultural run-off, cyanobacteria (blue-green algae), hypoxia (deficiency in oxygen), cladophora (green algae) to ice, invasive species, sediment concentrations, and much, much … [more…]

Bounty hunters and biologists wade deep into the Everglades to wrestle with the invasion of giant pythons threatening the state’s wetlands

In the Everglades, everything still looks the same. The waving saw grass, the cypress and pine trees draped with air plants, the high, … [more…]

Adjusting the water flow rate in a river can prevent invasive species from moving upstream and expanding their range. An applied mathematician at UT has developed a partial differential equation model to find the desired flow rate to reduce invasive populations.

The model is detailed in a new paper by Suzanne Lenhart, Chancellor’s Professor and James R. Cox Professor of Mathematics, published in Mathematics.

Invasive silver carp have been moving north toward the Great Lakes since their accidental release in the 1970s. The large filter-feeding fish, which are known to jump from the water and wallop anglers, threaten aquatic food webs as well as the $7 billion Great Lakes fishery. But, for the past decade, the invading front hasn’t moved past Kankakee. A new study, led by … [more…]

When Angie Hong is reaching out with water education in Washington County, it doesn’t matter if she’s talking to people who are conservative- or liberal-minded. “Everybody cares about water,” says Hong, who is with the East Metro Water Resources Education Program.

Hong would know. She has spent the last 12 years teaching … [more…]
