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.

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.

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.

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.

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.

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.

URBANA, Ill. -- Land is the planet’s limiting resource. We need land for food, biofuel, feed, ecosystem services, and more. But all land is not equal. Concerns about diverting land under food/feed crops to biofuel feedstocks have led to interest in using marginal land to produce these dedicated bioenergy crops for advanced biofuels. Marginal land has typically been defined as land that is of low quality and not in food crop production.

URBANA, Ill. -- Carbon is everywhere. It’s in the atmosphere, in the oceans, in the soil, in our food, in our bodies. As the backbone of all organic molecules that make up life, carbon is a very accurate predictor of crop yields. And soil is the largest carbon pool on earth, playing an important role in keeping our climate stable. 

As such, computational models that track carbon as it cycles through an agroecosystem have massive untapped potential to advance the field of precision agriculture, increasing crop yields and informing sustainable farming practices.

When she began her studies at the University of Illinois, Rachel Janovsky would not have pictured herself working for an international aircraft manufacturing company. A 2018 graduate of Natural Resources and Environmental Sciences (NRES), Janovsky has been able to leverage her College of Agricultural, Consumer and Environmental Sciences (ACES) degree to ensure the health and safety of employees at Honda.

An hour before the sun goes down, my colleagues and I arrive at our site: a human-made pond in the middle of the forest. The high-pitched croaking of Cope's gray treefrogs greets us as we get out of our truck. Surrounded by trees and full of salamanders, these ponds are an essential water resource for our forest-dependent bats. We do a brief survey of the site, then set up our mist nets around the pond’s perimeter. We’re hoping to catch our target species – the Indiana bat, Myotis sodalis.
