This broad category encompasses fish. It is further divided on the main menu with tags for mammals, insects, amphibians, birds, mussels, invaders and endangered wildlife.
The concentrations of dieldrin, an insecticide banned in 1978, are the greatest ever found in otters.
Once used on cornfields, the chemical lingers in sediments and accumulates in fish and wildlife.
Six Great Lakes states are among the nation’s top 12 corn producers.
Ecologist James Ludwig spent his career studying the chemical pollution of the Great Lakes – most notably with the help of his cross-billed cormorant, Cosmos.
Great Lakes Echo recently spoke with Ludwig about his new book, “The Dismal State of the Great Lakes.”
At the end of each month, Current State check in with Great Lakes commentator and journalist Gary Wilson for updates on environmental stories from around the basin. For this Great Lakes Month in Review, Gary focuses on ice cover and Asian carp fatigue. Wilson last spoke with Current State after the Army Corps’ study on Asian carp in the Great Lakes was released. Wilson says that carp fatigue has set in, meaning that Asian carp reports are in the news so frequently that people tend to tune it out.

In 32 years, there has rarely been a season when Michigan farmer and politician Ed McBroom, R-Vulcan, hasn’t found bear damage in his cornfield.
Now, he’s fighting to do something about it.
Severe winter weather may lead to the death of some invasive species, according to a recent study, but some experts aren’t convinced.
Endangered Kirtland’s warblers spend the summer nesting only in certain areas of Michigan, Wisconsin and Ontario.
They winter in the Bahamas. Researchers are using tiny light sensors to track how the birds travel between those areas.
Advances in technology help researchers track the birds to get a better understanding of their migration route to the Bahamas.
Opportunities of this magnitude to protect the Great Lakes are rare and don’t last forever.
Invasive species are a problem, but are they a death sentence for the ecosystems that they infect?
Not quite, according to a new university study.
Is hunting consistent with species recovery?
Editor’s Note: It’s an Echo tradition to revisit one of our favorite holiday stories: Tim Campbell’s The Twelve Days of Aquatic Invasive Species Christmas. Campbell rewrote the lyrics of the holiday tune for the Wisconsin Sea Grant in 2011. We’re publishing a new verse on each of the actual twelve days of Christmas.
On the tenth day of Christmas, a freighter sent to me…
Ten alewives croaking — Alewives are one of the few invasive species that foul Great Lakes beaches throughout the summer. Until the introduction of Pacific salmon, alewives died off in such great numbers that tractors were required to remove them from beaches. Salmon now do a great job controlling alewife numbers, but there are still alewife die-offs due to spawning-related stresses.
