The findings will improve methane estimates and models of climate change, and point to land-management changes and restoration opportunities that can reduce the amount of methane escaping into the atmosphere.
Climate change has affected Wisconsin trout species differently: Populations of smaller, brightly colored brook trout have declined, while numbers of larger brown trout have generally increased.
Phosphorus is only one part of the algae bloom recipe, research shows. Other key factors at play are calm winds, warm surface waters and a low abundance of tiny crustaceans called zooplankton.
Steve Carpenter, one of the world’s foremost lake ecologists, has been awarded an international prize for scientific research that has helped provide solutions to global environmental problems.
Researchers used water quality data and computer models to analyze the amount of salt being carried into Lake Michigan by 234 different tributaries, from major rivers to tiny streams.
“For many, many lakes, they are a very serious problem,” says Grace Wilkinson of the UW–Madison Center for Limnology. “But algal blooms are not getting worse everywhere."
The finding has important implications for the way we approach invasive species control and management, researchers say.
While decades of monitoring and regulatory efforts have paid little attention to these tiny tributaries, Mooney’s research shows that they play an outsized role in feeding algae blooms and impacting coastal waters.
New research could help lake managers make more informed decisions about their invasive species control strategies.
New research finds that It finds that 40 percent of walleye populations are overharvested, which is ten times higher than the estimates fisheries managers currently use.
“Stories from the Flood,” a collaboration involving UW–Madison, has gathered over 70 written, audio, and video interviews with people who experienced what some call a “thousand-year” flood along the Kickapoo River and nearby Coon Creek.
New research brings attention to the need to better manage recreational fisheries to protect the health of inland and near-shore fish populations and to preserve the recreational fishing experience.
Data visualizations generated by a Reddit competition reveal a concerning trend that’s been known to scientists at UW–Madison and elsewhere for decades: ice is disappearing on Lake Mendota.
A new study from an international team of researchers, including at UW–Madison, shows that many northern latitude lakes are at risk of experiencing some ice-free winters in the coming decades.
A new study has found that when droughts cause water levels to drop, the levels of mercury found in fish also plummet. In wetter weather, water levels rise and levels of mercury in fish increase.
