CHAMPAIGN, Ill. — The crops we grow in the field often form dense canopies with many overlapping leaves, such that young “sun leaves” at the top of the canopy are exposed to full sunlight with older “shade leaves” at the bottom. In order to maximize photosynthesis, resource-use efficiency, and yield, sun leaves typically maximize photosynthetic efficiency at high light, while shade leaves maximize efficiency at low light. 

CHAMPAIGN, Ill. — Northern bobwhites are attracted to a habitat based on whether other bobwhites are present there, researchers at the University of Illinois at Urbana-Champaign report. This phenomenon, called conspecific attraction, could aid conservation efforts.

URBANA, Ill. – Like antibiotic-resistant bacteria, some herbicide-resistant weeds can’t be killed by available chemicals. The problem affects more than just the errant weed in our driveways; herbicide-resistant weeds threaten our food supply, stealing resources and outcompeting the crops that make up our breakfast cereal and feed the nation’s livestock.

The weed that represents the biggest threat to Midwestern corn and soybean production, waterhemp, has outsmarted almost every kind of herbicide on the market today.

URBANA, Ill. – Soil microbes are living, working barometers of soil health. They are responsible for turning atmospheric nitrogen into forms plants can use, and for releasing nitrogen back into the air. Farm management decisions undoubtedly affect these microscopic workhorses, but, until now, scientists didn’t have a full picture of how crop rotation and tillage influence the soil microbiome.

CHAMPAIGN, Ill. — From tweeting photos of delicious meals to reviewing restaurants, social media give foodies numerous opportunities to indulge their passion for edibles. But these media and other digital communications — including recipe websites and food-delivery apps — also generate a rich trove of text data for food scientists and food industry researchers to study what people eat, how nutrition affects health and many other food-related topics.

URBANA, Ill. – Recent regulatory restrictions around antibiotic use in livestock challenge the feed industry, but research from the University of Illinois shows a probiotic product – Clostridium butyricum – can achieve the same growth-promoting results as antibiotics.

URBANA, Ill. – When the tree fell that October in 2015, the tropical giant didn’t go down alone. Hundreds of neighboring trees went with it, opening a massive 2.5-acre gap in the Panamanian rainforest.

Treefalls happen all the time, but this one just happened to occur in the exact spot where a decades-long ecological study was in progress, giving University of Illinois researchers a rare look into tropical forest dynamics.

URBANA, Ill. – When Matt Wheeler got the call on a Sunday morning in March – just two days after Gov. J.B. Pritzker issued his first stay-at-home order – he wasn’t expecting to launch an experiment that could save countless lives.

A global team of more than 500 researchers, including many experts in smell and taste perception, is investigating the abrupt loss of smell and taste – called anosmia and hypogeusia, respectively – in association with COVID-19 and whether these symptoms could help predict patients who may have the disease and could be at risk of being contagious.

URBANA, Ill. – Drought and heat put stress on plants and reduce grain yield. For some farmers, irrigation is the answer. Many of us assume the practice boosts crop yields by delivering soil water, but it turns out irrigation’s cooling effect on crops is important in its own right.

In a recent U.S.-based study, a research team led by University of Illinois scientists discovered 16% of the yield increase from irrigation is attributable to cooling alone.
