Imagine moving into a new house just to discover it has no insulation. That’s what life can be like for a bat box resident.

Bat boxes, a kind of artificial roost, are a simple and cost-effective way to increase habitat for these flying mammals. They’re a preferred spot for mother bats to raise pups if their favorite housing option, large dead trees, are hard to come by. But if improperly designed, bat boxes can end up hurting more than helping, Illinois bat researcher Joy O’Keefe says. 

A scientist in the College of Agricultural, Consumer and Environmental Sciences at the University of Illinois Urbana-Champaign is the recipient of the 2025 national agInnovation award for Excellence in Agricultural Research Innovation. 

Each fall, the College of Agricultural, Consumer and Environmental Sciences at the University of Illinois Urbana-Champaign welcomes thousands of students to campus.

Researchers at the University of Illinois Urbana-Champaign have analyzed 96 years of forest census data to better understand ecological changes and inform management practices. Their study, published in Forest Ecology and Management, reveals concerning homogenization trends. This means the forest has become less diverse over time, losing trees that played a critical role in its ecosystem.

Imagine a prairie. How many plant species do you see? Maybe you’re picturing yellow coneflowers, some little bluestem, perhaps a few asters. But plant ecologists at the University of Illinois Urbana-Champaign say these ecosystems are much more diverse than many people realize.

If you’ve ever been on a fishing boat, you might be familiar with live wells – small water tanks, built into the boat, where live fish can be stored. In bass fishing tournaments, these live wells keep fish alive throughout the competition, so that they can be released at the end. Anglers are always looking for ways to keep fish safe and healthy in these wells, since live bass mean higher prizes and more fish spawned for next year.

While the majority of Midwestern farmers rotate corn and soybeans, commodity prices and corn yield advantages compel some to plant corn year after year. Although foundational research on the benefits of corn-soybean rotation goes back decades, University of Illinois Urbana-Champaign scientists are working to address remaining holistic questions about crop yield, environmental impacts, and economic returns under various crop rotation scenarios. 

Faculty from the College of Agricultural, Consumer and Environmental Sciences are teaming up with the Brazilian Agricultural Research Corporation (Embrapa) on groundbreaking projects to tackle climate change and drive the future of the bioeconomy.  

The three selected projects from a competitive open call for proposals are: 

For decades, the Signal Crayfish has been an ecological troublemaker. It is invasive and widespread across Europe, Asia, and parts of the United States. Recently, researchers at the University of Illinois Urbana-Champaign turned their attention back to the Signal Crayfish’s homeland and made a remarkable discovery.

A nine-year study comparing a typical two-year corn and soybean rotation with a more intensive three-year rotation involving corn, cereal rye, soybean and winter wheat found that the three-year system can dramatically reduce nitrogen — an important crop nutrient — in farm runoff without compromising yield.

The new findings are detailed in the journal Frontiers in Environmental Science.
