Building a better bat box: Temperature variation in rocket box designs
URBANA, Ill. – Bat box designs vary widely, but many commercial varieties remain untested and risk cooking the animals they’re designed to shelter. Often small and painted dark colors, these boxes may rise to dangerous temperatures on sunny days in summer, putting mom and pup in harm’s way.
The heat is on: RIPE researchers show ability to future-proof crops for changing climate
CHAMPAIGN, Ill., U.S. — The world is warming quickly with no indication of slowing down. This could be catastrophic for the production of food crops, particularly in already warm areas. Today, research from the University of Illinois and the U.S. Department of Agriculture Agricultural Research Service shows that bypassing a photosynthetic glitch common to crops like soybean, rice, and wheat, can confer thermal protection under heat stress in the field.
Study clarifies nitrogen’s impact on soil carbon sequestration
URBANA, Ill. – Soil organic carbon is a cornerstone of soil health. It improves soil structure while enhancing water- and nutrient-holding capacity, key factors for any agricultural production system. To build it up, farmers incorporate crop residues into soils.
So why, despite decades of residue inputs, is soil organic carbon diminishing in corn production systems? Short answer: it’s the nitrogen.
Nitrogen calculators not created equal, according to Illinois study
URBANA, Ill. – When deciding how much nitrogen fertilizer to apply, farmers have options. The standard tool for the Midwest – the maximum return to nitrogen (MRTN) calculator – offers a static recommendation. It is based on hundreds of field trials, but doesn't vary much year to year.
Brawn honored as inaugural Levenick Chair in Sustainability
URBANA, Ill. – In January 2020, professor Jeffrey Brawn was named the inaugural Stuart L. and Nancy J. Levenick Chair in Sustainability, the first endowed chair in the Department of Natural Resources and Environmental Sciences (NRES) at the University of Illinois. A pandemic-belated ceremony happened yesterday on the Urbana campus.
Sending up the bat signal on forest use by endangered species
URBANA, Ill. – Deep in an Indiana forest, a team of scientists skulked atop hillsides after dark. Carrying radios and antennas, they fanned out, positioning themselves on opposite ridges to wait and listen. Their quarry? Endangered Indiana bats and threatened northern long-eared bats.
Study reconstructs 232-year history of prairie fire in Midwestern US
URBANA, Ill. -- Researchers combed through thousands of historical documents for first-person accounts of fires occurring between 1673 and 1905 in the Midwestern tallgrass prairie. Their study is the first systematic analysis of the timing, causes and consequences of prairie fires in this part of the world. They report their findings in Natural Areas Journal.
Anglers need tailored messaging to inspire action on invasive species
URBANA, Ill. – Once aquatic invasive species establish, they typically refuse to budge. That’s why it’s critical to prevent invasive quagga mussels, Eurasian watermilfoil, and other bad actors from getting established in the first place.
Team discovers invasive-native crayfish hybrids in Missouri
CHAMPAIGN, Ill. — In a study of crayfish in the Current River in southeastern Missouri, researchers discovered – almost by chance – that the virile crayfish, Faxonius virilis, was interbreeding with a native crayfish, potentially altering the native’s genetics, life history and ecology. Reported in the journal Aquatic Invasions, the study highlights the difficulty of detecting some of the consequences of biological invasions, the researchers say.

USDA funds ‘agrivoltaics’ project led by iSEE team
Urbana, Ill. – The U.S. Department of Agriculture (USDA) has announced funding for a new project led by iSEE Interim Director Madhu Khanna, Department of Agricultural and Consumer Economics, to optimize design for “agrivoltaic” systems – fields with both crops and solar panels – that will maintain crop production, produce renewable energy, and increase farm profitability.
