URBANA, Ill. – Since they were first released as live bait in the mid-twentieth century, rusty crayfish have roamed lake bottoms in northern Wisconsin, gobbling native fish eggs, destroying aquatic plants, and generally wreaking havoc on entire lake ecosystems. Today, in some lakes, traps can routinely pull up 50 to 100 rusty crayfish at a time, compared to two or three native species. But in other lakes nearby, populations seem to be declining.

URBANA, Ill. – The U.S. Corn Belt produces about a third of the world’s corn and soybean supply, but with further intensification and a changing climate, it’s not clear whether the Corn Belt can remain environmentally sustainable over the long term. With a new five-year project, funded by the National Science Foundation’s flagship CAREER award, Illinois scientist Kaiyu Guan aims to find out.

URBANA, Ill. – Spending time in nature boosts children’s academic achievement and healthy development, concludes a new analysis examining hundreds of studies.

The following are reflections from Yushu Xia, a PhD student in the Department of Natural Resources and Environmental Sciences, on her research project partially funded by an ACES International Graduate Grant: “Improving Agricultural Nitrogen Models for Nitrogen Management Assessment at a Field Spatial Scale.” Yushu’s advisor is Dr. Michelle Wander.

From classifying mosquitos in the Amazon to conserving natural resources in a war zone, Dr. McKenzie Johnson brings significant international experience to the College of Agricultural, Consumer and Environmental Sciences (ACES), where she recently joined the faculty as an assistant professor in the Department of Natural Resources and Environmental Sciences.  

Johnson is also a recent recipient of an ACES International Seed Grant for a project she will initiate this spring: “Environment and Post-Conflict Peacebuilding in Colombia.”

URBANA, Ill. – During the Vietnam War, United States aircraft sprayed more than 20 million gallons of herbicides, including dioxin-contaminated Agent Orange, on the country’s rain forests, wetlands, and croplands. Agent Orange defoliated the thick jungle vegetation concealing Viet Cong fighters and destroyed a portion of the country’s food crops, but it was primarily the dioxin contaminant that harmed so many Vietnamese and U.S. military personnel.

URBANA, Ill. — Sustainability leadership, research, education, and practices will remain at the forefront of University of Illinois priorities, thanks in part to significant endowments from Stuart L. and Nancy J. Levenick of Naples, Florida.

Mr. Levenick, a U of I alumnus who captained the 1975 Illini football team and received a B.S. in forestry in 1976, and his wife have designated this major endowment in two parts:

URBANA, Ill. – At the southern tip of the Himalayas, farmers in the Kangra region of India’s Himachal Pradesh graze cattle among rolling hills and forests. The forests, under management by the state or farmer cooperatives, are thriving. But a new University of Illinois study shows, unlike state-managed forests, farmer cooperatives directly benefit both forest health and farmers.

After they hatch, deer ticks take two years to reproduce. In that time, they morph from tiny larvae to nymphs to adults, with each stage feeding on a different group of host animals. For researchers studying the dynamics of Lyme disease, understanding host-tick interactions could reveal weak spots that may leave ticks vulnerable to control. A recent University of Illinois study simulates these interactions and provides guidance for effective management.

URBANA, Ill. – Many anglers know invasive species cause problems in their favorite fishing spots, but a smaller subset routinely acts to prevent aquatic hitchhikers on boats and other equipment. What sets these anglers apart? A recent study from the University of Illinois attempts to answer that question from a social science perspective.
