  • Road block: Fixing aquatic ecosystem connectivity doesn’t end with dams May 29, 2013 Over the last several years, state agencies and environmental nonprofit organizations have targeted dam removal as a way to quickly improve the health of aquatic ecosystems. Dams keep migratory fish from swimming upriver to spawn, block nutrients from flowing downstream, and change the entire hydrology of a watershed. From an ecosystem perspective, taking down a dam and returning a river to a more natural flow seems like a no-brainer.
  • ‘Audio field trip’ to celebrate campus wetland and remember campus zoologist May 24, 2013 An "audio field trip" on Memorial Day will explore a restored marsh on the University of Wisconsin-Madison campus - a part of the university's Lakeshore Nature Preserve. The marsh, near the western end of campus, is a remnant of a much larger wetland that was drained for other uses such as growing corn.
  • Invasive fish enters streams feeding Lake Michigan, but so far, so good Jan. 18, 2013 Invasive species are known for disturbing their new homes. Whether it's the zebra mussels in the Great Lakes or garlic mustard in native woodlands, their rampant multiplication crowds out native species.
  • Mapping effort charts restoration tack for Great Lakes Dec. 17, 2012 As the federal government builds on its $1 billion investment to clean up and restore the Great Lakes, an international research consortium has developed innovative new maps of both environmental threats and benefits to help guide cost-effective approaches to environmental remediation of the world’s largest fresh water resource.
  • Photo: Lake mixing experiment Stirred, not shaken, lake mixing experiment shows promise Nov. 5, 2012 The question is simple: can a lake be cleansed of a pernicious invader by simply raising the water temperature?
  • Deep freeze has yet to hit Madison lakes Dec. 27, 2011 Wide swaths of lawn aren’t the only odd sight on campus this late in December. There is still all kinds of open water on either side of Madison’s isthmus, as ice has yet to take hold on lakes Mendota or Monona.
  • UW-Madison global fishery expert wins prestigious fellowship Oct. 17, 2011 Peter McIntyre, an assistant professor of zoology at the University of Wisconsin-Madison, has won an $850,000, five-year Packard Fellowship for Science and Engineering from the David and Lucile Packard Foundation.
  • Eleven professors appointed to named professorships Oct. 6, 2011 Eleven distinguished faculty members have received named professorships, some of the highest honors for established faculty.
  • UW–Madison limnologist receives international Water Prize Aug. 25, 2011 Sweden’s King Carl XVI Gustaf presented Steve Carpenter, University of Wisconsin–Madison Stephen Alfred Forbes Professor of Zoology and director of the Center for Limnology, with the Stockholm Water Prize today (Aug. 25) in a ceremony at the 2011 World Water Week conference in Stockholm.
  • Scientists detect early warning signal for ecosystem collapse April 28, 2011 Researchers eavesdropping on complex signals emanating from a remote Wisconsin lake have detected what they say is an unmistakable warning - a death knell - of the impending collapse of the lake's aquatic ecosystem.
  • Artists, scientists collaborate on exhibit focusing on ecological change April 11, 2011 In the popular imagination, the thought processes of artists and scientists could hardly be more distinct. And yet a year-long collaboration of lake scientists and artists from northern Wisconsin has engaged both sides of the "divide" in understanding and communicating the changing ecology in one of the world's densest group of lakes - in the northern highlands of Wisconsin.
  • Photo: Stephen Carpenter UW-Madison lake scientist gets world's top water prize March 22, 2011 Noted University of Wisconsin-Madison limnologist Stephen Carpenter has been awarded the 2011 Stockholm Water Prize, the world's most prestigious award for water-related activities, it was announced in Stockholm, Sweden today (Tuesday, March 22).
  • UW-Madison trio named Leopold Leadership Fellows Feb. 28, 2011 Three University of Wisconsin-Madison professors are among only 20 academics from throughout North America chosen this year to participate in a prestigious environmental leadership and communications training program.
  • World phosphorous use crosses critical threshold Feb. 14, 2011 Recalculating the global use of phosphorous, a fertilizer linchpin of modern agriculture, a team of researchers warns that the world's stocks may soon be in short supply and that overuse in the industrialized world has become a leading cause of the pollution of lakes, rivers and streams.
  • Portion of map Expanding croplands chipping away at world’s carbon stocks Nov. 1, 2010 Nature's capacity to store carbon, the element at the heart of global climate woes, is steadily eroding as the world's farmers expand croplands at the expense of native ecosystem such as forests.
  • Portion of info graphic Report casts world’s rivers in ‘crisis state’ Sept. 29, 2010 The world's rivers, the single largest renewable water resource for humans and a crucible of aquatic biodiversity, are in a crisis of ominous proportions, according to a new global analysis.
  • GLEON buoy Global grassroots lake science network has roots in Wisconsin July 19, 2010 Inspired and led by freshwater scientists at the University of Wisconsin-Madison, researchers eager to understand global ecosystems from end to end are now monitoring a series of buoys in lakes on every continent except Africa. Each buoy carries instruments to measure fundamental data on the weather above the water and the temperature and chemistry below it.
  • Where the invasive things are — and where they could be March 9, 2010 Researchers at the University of Wisconsin-Madison's Center for Limnology have launched a new Web site to help assess the threat of aquatic invasive species in Wisconsin's lakes.
  • Student on Limnos doing field research UW-Madison undergraduates make unwelcome discovery in Lake Mendota Sept. 16, 2009 On Sept. 11, a standard cruise on Lake Mendota's University Bay began for students in University of Wisconsin-Madison's Zoology 315, a course that introduces them to the study of lakes. With the sampling craft Limnos anchored about one-quarter mile offshore on a clear sunny day, four students pulled up a small net and began poking through its contents.
  • UW-Madison's 'good ideas' get lift from stimulus funds Aug. 26, 2009 The university has drawn more than $38 million in funding for more than 120 research projects and programs from the American Recovery and Reinvestment Act. The work is spread across the range of academic disciplines, including public health, computer science, psychology, economics and engineering. Funding comes from agencies such as NSF, the National Institutes of Health (NIH), the Department of Energy and the National Endowment for the Arts.
