Research explains connections between wolf and moose populations in northern Minnesota
Growing wolf populations reduce moose calf survival, while fewer moose mean hard times for their primary predators.
Scientists: Northern Minnesota’s rising deer population to blame for dwindling moose numbers
Extensive studies of moose mortality show parasites carried by whitetail deer are killing many of Minnesota’s remaining moose.
Remote lakes on Isle Royale are turning toxic and we don’t know why — yet
Scientists recently discovered more harmful algae blooms at the National Park in Lake Superior, a surprising problem for pristine waters surrounded by unbroken forests.
Study: No connection between forest fires and mercury levels in fish
Measuring mercury in two different lakes before and after, and absent, fires showed fears about short-term contamination are unfounded.
Report: Northwoods Bird Numbers Are Healthy, Mostly
The populations of most species are steady or growing, but there are a few causes for concern.
Paddlers Needed to Collect Water Clarity Data in the Boundary Waters
The Minnesota Pollution Control Agency is seeking volunteers to help monitor conditions in remote wilderness lakes.
Not Gone Yet: Scientists Find Evidence of Wolves on Isle Royale
Tracks frozen in slush on a wilderness lake have given the first indication that at least a couple wolves are still holding on despite a crashing population and little chance of reproduction.
Inaugural Heart of the Continent Science Symposium Will Share Canoe Country Research
Conference offers opportunity for researchers working throughout the region to present about their discoveries.

Protecting Our Wild Rice Heritage
Evaluating Minnesota’s water sulfate standard for wild rice. The Minnesota Pollution Control Agency is reviewing its standards for protecting wild rice in Minnesota. With funding from the Minnesota State Legislature, the agency conducted a two-year study to determine how sulfate—the presence of which in water has been linked to an absence of wild rice—and other chemicals affect the health of wild rice.
Mercury Levels Drop in Wild Northern Minnesota Lakes
Research attributes reductions of the toxic metal in water and fish samples to restrictions on emissions.
Study of Mine Waste Impacts on Wild Rice Released
Research on how sulfates affect the official state grain of Minnesota will be used to determine if a key water quality standard should be changed.
Using Science for Sustainable Forest Management
The long-range health of Minnesota’s forests will some day be improved by management decisions that better recognize the opportunities for restoring ecological forest health while maintaining economic productivity. The Minnesota Center …
