Balancing birds and biofuels: Grasslands support more species than cornfields
In Wisconsin, bioenergy is for the birds. Really. In a study published today in the journal PLOS ONE, University of Wisconsin–Madison and Wisconsin Department of Natural Resources (DNR) scientists examined whether corn and perennial grassland fields in southern Wisconsin could provide both biomass for bioenergy production and bountiful bird habitat. The research team found that where there are grasslands, there are birds. Grass-and-wildflower-dominated fields supported more than three times as many bird species as cornfields, including 10 imperiled species found only in the grasslands.
Next wave of research: Ecology, super-sized
The University of Wisconsin–Madison, home of pioneering ecologists who studied lakes, forests, wetlands and prairies, is playing a key role in the next wave of ecological research: large teams of scientists confronting the dilemma of a changing climate on a shrinking planet.
Madison Reads Leopold set for Saturday at UW Arboretum
The UW Arboretum's ninth annual Madison Reads Leopold event anchors the celebration of Aldo Leopold Weekend in the Madison area with a mix of citizen and celebrity readers giving voice to Leopold's "A Sand County Almanac."
Seed dispersal gets a test in carved-out ‘habitat corridors’
Field ecologists go to great lengths to get data: radio collars and automatic video cameras are only two of their creative techniques for documenting the natural world. So when a group of ecologists set out to see how wind moves seeds through isolated patches of habitat carved into a longleaf pine plantation in South Carolina, they twisted colored yarn to create mock seeds that would drift with the wind much like native seeds.
Study puts freshwater biodiversity on the map
When it comes to economic growth and environmental impacts, it can seem like Newton's third law of motion is the rule - for every action, there is an equal and opposite reaction - and that in most cases, the economy prospers and the environment suffers.
Scientists find early warning indicators of major ecological change
Day after day, the buoy bobbed at the surface of Peter Lake. Every five minutes, or 288 times a day, instruments in the water silently recorded samples without creating so much as a ripple. But, beneath the surface, the lake - just across Wisconsin's northern boundary in Michigan's Upper Peninsula - was in turmoil. The buoy was busy documenting massive change.
Ecologists map the benefits of our ecosystems
Two ecologists at the University of Wisconsin–Madison report this week (July 1) in the Proceedings of the National Academy of Sciences a novel approach to analyzing the production and location of 10 different ecosystem services across a landscape, opening the door to being able to identify factors governing their synergies and tradeoffs.
Water, water everywhere focus of new sustainability project
An interdisciplinary team of scientists and engineers at the University of Wisconsin–Madison is turning a comprehensive lens on Madison's water in all its forms - in the lakes, streets, faucets, ground and atmosphere - thanks to the National Science Foundation.
Plant family tree may help identify species vulnerable to invaders, climate change
Change has been the norm for Wisconsin's forests over the last 50 years, and the next 50 are unlikely to pass quietly.
Migratory birds bear brunt of climate-charged weather
As global climate change fuels more frequent and intense hurricanes and droughts, migratory birds, especially those whose populations are already in decline, will bear the brunt of such climate-fueled weather, suggest a pair of new studies.
Conservation areas threatened nationally by housing development
Conservationists have long known that lines on a map are not sufficient to protect nature because what happens outside those boundaries can affect what happens within. Now, a study by two University of Wisconsin–Madison scientists in the department of forest and wildlife ecology measures the threat of housing development around protected areas in the United States.
Surveying bird biodiversity from space?
A fundamental rule of wildlife ecology says that diverse habitats foster greater biodiversity: The Amazon has far more species than Greenland. But how do habitat and biodiversity relate in a state like Wisconsin, with its range of farms, forests, wetlands, cities, suburbs and highways?
Greenhouse gas carbon dioxide ramps up aspen growth
The rising level of atmospheric carbon dioxide may be fueling more than climate change. It could also be making some trees grow like crazy.
