The past attempts of honey bee researchers to inventory the fungal diversity in honey bee colonies revealed that Aspergillus flavus is frequently found in hives. In a new study, researchers have discovered that this fungus is uniquely adapted to survive in bee colonies.The...
Have you ever wondered how plants protect themselves from predators? This is a question Erinn Dady addresses in her research as a graduate student in the Department of Entomology.Dady grew up in Champaign-Urbana. Prior to becoming a...
Plant biologists report that a species of tree fern found only in Panama reanimates its own dead leaf fronds, converting them into root structures that feed the mother plant. The fern, Cyathea rojasiana, reconfigures these “zombie leaves,” reversing the flow of water to draw nutrients back...
It has long been known that exposure to pesticide sprays is harmful to honey bees. In a new study, researchers have uncovered the effect of such sprays on the sense of smell in bees, which could disrupt their social signals.Honey bees live in dynamic communities and constantly communicate with each...
Ozone (O3) in the troposphere negatively impacts crop growth and development, causing significant decreases in crop yield worldwide. This airborne pollutant does not come directly from smokestacks or vehicles, but instead is formed when other pollutants, mainly nitrogen oxides and volatile organic...
CHAMPAIGN, Ill. — Researchers report that a single, simplified model can predict population fluctuations in three unrelated realms: urban employment, human gut microbiomes and tropical forests. The model will help economists, ecologists, public health authorities and others predict and respond to...
A five-year study at the University of Illinois Energy Farm found applying ground-up silicate rock to Midwestern farm fields can capture significant amounts of carbon dioxide and prevent it from accumulating in the atmosphere.Working with Eion Corp., researchers at the University of Illinois Urbana...
Like many ecological scientists, University of Illinois Urbana-Champaign plant biology professor James O’Dwyer has spent much of his career searching for ways to measure and predict how specific plant communities...
More than four decades ago, field ecologists set out to quantify the diversity of trees on a forested plot on Barro Colorado Island in Panama, one of the most intensively studied tracts of forest on the planet. They began counting every tree with a trunk wider than a centimeter.They identified the...
A new look at decades of data from museum collections and surveys of leaf-litter ants in Florida reveals a steady decline in native ants and simultaneous increase in nonnative ants – even in protected natural areas of the state, researchers report.The study tracked leaf-litter ant abundance from...
