A glade with the regional endemic wildflower Ozark coneflower (Echinacea paradoxa) in bloom, with a gum Bumelia tree in the background. Native wildflowers such as this coneflower are threatened by woody encroachment of glades.
The following is a guest post from Jesse Miller, a former graduate student at UW–Madison in the lab of Ellen Damschen and a current postdoctoral researcher at the University of California-Davis. He summarizes a paper he and his research team recently co-authored in the journal Landscape Ecology: Grasslands are home to […]

Fire may help Ozarks grasslands

According to a recently published study, invasive quagga mussels in Lake Michigan, paired with decreasing nutrient availability, could explain an observed decline in food chain productivity in Lake Michigan. Currently, Lake Michigan is in the midst of a decade-long decline in food chain productivity, or the lake’s ability to produce […]

Perhaps you’ve noticed: It’s spring and the Plants Are Blooming. Maybe it’s the smell of the lilacs, or the buzzing of bees. Or perhaps it’s the lush greens and bursts of color blurring your field of vision. But have you ever wondered how the landscape transitions from the brown drab of […]

This winter may now feel a shade lonelier for a handful of bumble bee princesses tucked away underground in the University of Wisconsin–Madison Arboretum, but they will probably wake up in the spring to a larger group of human admirers. This week, the U.S. Fish and Wildlife Service declared rusty-patched […]

Biking, for science



Fish near the shore of a lake
Last Wednesday, the Center for Limnology at UW-Madison shared the following tweet from a graduate student in the department: If you’re near @WiscLimnology or @LakeMendota today – stop by the shoreline to witness carp spawning. Hundreds of carp + clear water phase! — Samantha Oliver (@limnoliver) May 25, 2016 We wasted […]

Clear water in Lake Mendota is a chance to watch ...
