As fall slowly hardens to winter in Madison, part of Karen Oberhauser’s new job is to walk the trails of the UW–Madison Arboretum, getting a sense not just for the geography, but for the land itself. That’s because the land Oberhauser walks is now under her care.
“It’s a generally thorny problem and we are often scrambling to react,” says lead principal investigator Monica Turner. “In fact, understanding abrupt change in ecological systems is among the biggest challenges in contemporary ecology.”
The worms churn through leaf litter at a faster clip than their more sluggish earthworm cousins, potentially processing nutrients faster than plants are able to use them and disrupting ecosystems.
As part of her master of fine arts thesis, Liz Anna Kozik has installed an exhibit telling the story of the first restored prairie in the world, Curtis Prairie at the UW–Madison Arboretum.
More than three decades of data on the physical, chemical and biological variables in 11 Midwestern lakes show that while lake temperatures and nutrient concentrations rise within relatively expected ranges, biological organisms achieve high population extremes.
Research into the insects' behavior aims to better understand lake-dominated environments, including those of Wisconsin.
A proposal by the U.S. Fish and Wildlife Service to seek endangered status for the rusty-patched bumblebee has focused renewed attention on bumblebees living in the 1,200-acre natural area.
A new study shows how and where changing climate conditions could affect the communities of species in any given area. In …
“It’s not only western forests where these things matter, where disturbances and changing environments shape regional landscapes,” says Wisconsin researcher Monica Turner.
A UW–Madison research group has documented an exodus of owls following the fierce, 99,000 acre King Fire in California in 2014.
UW Arboretum land care staff member Austin Pethan uses a drip torch as a 10-person staff manages a prescribed fire at Juniper Knoll on March 29. Fire is used as a wildland management tool to help control competing vegetation, reduce potential buildup of excess flammable materials, and perpetuate fire-dependent species.
UW researchers report that the range of the snowshoe hare in Wisconsin is creeping north by about five and a half miles per decade.
Researchers have found that human influence has accelerated the rate of species change in these prairies and likely in other natural places.
