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.
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.
Natural resources path attracts record number of world changers
URBANA, Ill. – This fall, the Department of Natural Resources and Environmental Sciences (NRES) is teaching and guiding its highest-ever number of undergraduates. Passion for preserving and restoring the environment helped drive the enrollment high.

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.
Grant funds study of free-living nitrogen fixers in organic systems
URBANA, Ill. – Organic farmers often struggle to meet the nitrogen demands of corn and other crops. Unlike conventional farmers, with their easy access to inexpensive inorganic nitrogen fertilizers, fewer commercial options are available for organic growers.
Study links COVID-19 rates with nature equity, shows double burden for communities of color
URBANA, Ill. – By now, it’s clear the COVID-19 pandemic has been particularly unkind to communities of color and low-income populations. The Centers for Disease Control and Prevention ties these disparities to disproportionate representation of nonwhite populations in essential worker roles, discrimination, lack of healthcare access, wage gaps, housing factors, and more.
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.

Crayfish get more interesting at bigger parties, study suggests
URBANA, Ill. – In many North American lakes, a tiny clawed creature has become a big bully. The invasive rusty crayfish roams lakebeds, snapping up snails, bivalves, and water plants, cutting off food supplies for native crayfish and other animals. And when they’re feeling saucy, some mount daring raids on fish eggs, reducing sport-fish populations.
Advanced model and field data add up to better cover crop management
URBANA, Ill. – Cover crops are widely seen as one of the most promising conservation practices, improving soil health while also removing carbon from the atmosphere. But while the number of Midwestern farmers planting cover crops has increased markedly in recent years, 2017 USDA Census data show only about 5% have adopted the conservation practice. The reluctance of the other 95% may be due, in part, to a perception that cover crops require more effort and may also negatively affect summer cash crop yield.
