  • Honey bee hives placed near flowering prairies in late summer and early fall were much healthier than those left near soybean fields after August, the researchers found.

    A little prairie can rescue honey bees from famine on the farm, study finds

    Scientists placed honey bee hives next to soybean fields in Iowa and tracked how the bees fared over the growing season. To the researchers’ surprise, the bees did well for much of the summer. The colonies thrived and gained weight, building up their honey stores. But in August, the trend reversed. By mid-October, most of the honey was gone and the overwintering brood was malnourished, the team discovered.

  • A new study reveals genetic differences that influence how corn responds to higher concentrations of ground-level ozone.

    Study finds rising ozone a hidden threat to corn

    Like atmospheric methane and carbon dioxide, ground-level ozone is on the rise. But ozone, a noxious chemical byproduct of fossil fuel combustion, has received relatively little attention as a potential threat to corn agriculture.

    A new study begins to address this lapse by exposing a genetically diverse group of corn plants in the field to future ozone levels. The study found that some members of the corn family tree are more susceptible than others to yield losses under high ozone air pollution.

  • Auriel Fournier, the director of the Forbes Biological Station at the Illinois Natural History Survey, studies the migratory behavior of purple martins.

    Purple martin migration behavior perplexes researchers

    Purple martins will soon migrate south for their usual wintertime retreat, but this time the birds will be wearing what look like little backpacks, as scientists plan to track their roosting sites along the way. The researchers recently discovered that purple martins are roosting in small forest patches as they migrate from North America to Brazil, an unexpected behavior. The scientists published their findings in the Journal of Field Ornithology. 

  • University of Illinois researchers Jeremy Guest, left, John Trimmer and Daniel Miller have developed a conceptual roadmap to help guide others through the unexplored environmental and economic aspects of sanitation.

  • Illinois Sustainable Technology Center researchers Elizabeth Meschewski, left, and Nancy Holm and collaborators developed a systematic study to test the effectiveness of the soil additive biochar and found that it may not be as effective as previously thought.

    Biochar may boost carbon storage, but benefits to germination and growth appear scant

    Biochar may not be the miracle soil additive that many farmers and researchers hoped it to be, according to a new University of Illinois study. Biochar may boost the agricultural yield of some soils – especially poor quality ones – but there is no consensus on its effectiveness. Researchers tested different soils’ responses to multiple biochar types and were unable to verify their ability to increase plant growth. However, the study did show biochar’s ability to affect soil greenhouse gas emissions.

  • Plant biology professor Evan DeLucia and his colleagues found that hotter conditions expected by midcentury will lead to a need for crop irrigation in the Midwest, a region that relies primarily on rainfall to grow crops.

    A warming Midwest increases likelihood that farmers will need to irrigate

    If current climate and crop-improvement trends continue into the future, Midwestern corn growers who today rely on rainfall to water their crops will need to irrigate their fields, a new study finds. This could draw down aquifers, disrupt streams and rivers, and set up conflicts between agricultural and other human and ecological needs for water, scientists say.

    Corn better used as food than biofuel, study finds

    Corn is grown not only for food, it is also an important renewable energy source. Renewable biofuels can come with hidden economic and environmental issues, and the question of whether corn is better utilized as food or as a biofuel has persisted since ethanol came into use. For the first time, researchers at the University of Illinois have quantified and compared these issues in terms of economics of the entire production system to determine if the benefits of biofuel corn outweigh the costs.
