Wolves reintroduced to Isle Royale temporarily affect other carnivores, humans have influence as well
While many studies have been conducted to understand the effects of a carnivore reintroduction on their prey, less well studied is the effect of the reintroduction on other carnivores in the same food web, in this case foxes and martens.
Inaugural Bassam Z. Shakhashiri Public Science Engagement Award recognizes excellence in outreach
A conservation scientist with a goal of finding ways to equitably protect tropical forest biodiversity and a teaching faculty member whose outreach work has led to a method for teaching visually impaired students about nanotechnology received the award.
Carnivores living near people feast on human food, threatening ecosystems
While evolution has shaped these species to compete for different resources, their newfound reliance on a common food source could put them in conflict with one another.
Woodland hawks flock to urban buffet
A team of Wisconsin researchers documents that woodland hawks — once in precipitous decline — have become firmly established in urban environments, thriving primarily on a diet of backyard birds.
Martens recolonized Isle Royale in the ’90s, showing island’s dynamism
The results of a new study provide much-needed context about the natural history of an island long considered an unspoiled wilderness, but one with a long history of ecological disruptions and recoveries.
Trail cam project Snapshot Wisconsin goes statewide
Starting Aug. 9, the Wisconsin Department of Natural Resources invites volunteers from all 72 counties to apply to run a trail cam in their part of Wisconsin, and will allow the cameras to be hosted on public land for the first time.
Study bolsters bats’ reputation as mosquito devourers
New UW–Madison research conducted throughout Wisconsin suggests that bats may indeed be effective exterminators of mosquitoes.
CWD prions discovered in soil near Wisconsin mineral licks for the first time
New research out of the UW–Madison has, for the first time, detected prions responsible for chronic wasting disease (CWD) in samples taken from sites where deer congregate.
Bird observing course an experience in finding passion for nature
In the Birds of Southern Wisconsin course, students must sometimes brave the elements to collect observations of Wisconsin’s overwintering and migratory birds.
Tribal forests in Wisconsin are more diverse, sustainable
Researchers found that many of the differences between tribal and nontribal forests can be traced back to the lower density of deer on the tribal lands.
More homes built near wild lands leading to greater wildfire risk
New research out of the University of Wisconsin–Madison shows that a flurry of homebuilding near wild areas since 1990 has greatly increased the number of homes at risk from wildfires while increasing the costs associated with fighting those fires in increasingly dense developments.
Aldo Leopold’s writings given voice March 3 at UW Arboretum
The 13th annual Madison Reads Leopold event on Saturday, March 3, will feature a reading of the influential conservationist’s “A Sand County Almanac” and other writings.
Urban foxes and coyotes learn to set aside their differences and coexist
Diverging from centuries of established behavioral norms, red fox and coyote have gone against their wild instincts and learned to coexist in the urban environment of Madison and the University of Wisconsin–Madison campus.
Invasive worms spreading in Arboretum forests, limited effects so far
Despite Asian jumping worms’ known appetite for leaf litter and tendency to change soil nutrients, researchers found limited evidence of changes to vegetation in areas where the worms have invaded the UW–Madison Arboretum.
Scouting the eagles: Evidence that protecting nests aids reproduction
Reproduction among bald eagles in a remote national park in Minnesota was aided when their nests were protected from human disturbance, according to a new study.
Lake Michigan waterfowl botulism deaths linked to warm waters, algae
UW-Madison researchers, with the help of citizen scientists, tracked bird deaths along Lake Michigan, and found that warm waters and algae apparently promoted the growth of botulism toxin-producing bacteria that caused them.
UW–Madison professor led fight to ban pesticide DDT 45 years ago
Joseph Hickey took a brave stance — given Wisconsin’s deep roots in agriculture — by showing a connection between pesticides and declining bird populations.
Monkey study shows a path to monitoring endangered species
“We think this may be one of the most comprehensive efforts to analyze the data monitoring needs for ensuring the survival of an endangered animal,” says Karen Strier, who has observed muriquis in Brazil for 35 years.
Decades-past logging still threatens spotted owls in national forests
Researchers say despite protections put in place in the 1990s, owls may still be paying an “extinction debt” that was created by historical logging of large trees.
Tropical trees show coexistence is path to diversity
The findings confirm that climate seasonality plays a role in the higher biodiversity scientists observe near the equator, but they highlight that this coexistence mechanism also varies with latitude.
