Evolution, Ecology, and Behavior

In the midst of the grief, confusion and anger of the past few months, many Americans have developed a new obsession with the creepy little things in life, by which I mean bugs. I’ve never heard so many people talking about bugs as I have through this spring and summer, never seen so many social...

Some birds lay their eggs in the nests of other bird species and let the host parents raise their young. A new study finds that in times of environmental flux, these brood parasites “diversify their portfolios,” minimizing the risks...

Researchers have developed a simple model to study how ants balance their large heads relative to their body size. Such models may have useful applications in bio-inspired designs. They use a variety of modelling approaches to study form and function. By using a basic biomechanical model for...

Brown-headed cowbirds show a bias in the sex ratio of their offspring depending on the time of the breeding season, researchers report in a new study. More female than male offspring hatch early in the breeding season in May, and more male hatchlings emerge in July.

What do Covid-19, Ebola, Lyme and AIDS have in common? They jumped to humans from animals after we started destroying habitats and ruining ecosystems.

Dear SIB Community, At the end of May, 2020, Chancellor Jones sent out an email with a powerful message of unity for this campus - we must come together and care for one another. He reminds us that the University of Illinois is a "...

This is the story of three bird species and how they interact. The brown-headed cowbird plays the role of outlaw: It lays its eggs in other birds’ nests and lets them raise its young – often at the expense of the host’s nestlings. To combat this threat, yellow warblers have developed a special “...

Researchers sequenced the genome of the orangethroat darter, pictured, and compared it with that of the rainbow darter, a closely related species. They also hybridized the two species to determine the factors that drive them to diverge.

Eight professors at the University of Illinois at Urbana-Champaign, to include Entomology's and EEB's Andrew Suarez, have been elected 2019 Fellows of the American Association for the Advancement of Science. Suarez, a...
