- Females spend more time at nest after hearing cowbird alarm
Across North America, hundreds of bird species waste time and energy raising chicks that aren’t their own. They’re the victims of a “brood parasite” called the cowbird, which adds its own egg to their clutch, tricking another species into raising its offspring.
2021-10-20 - Wildflowers peek their heads through the grass. An eastern tailed-blue butterfly flits among the tall, swaying blades as a red-winged blackbird flies overhead. When Fred Delcomyn looks outside, this is what he might see. In 2001, when he and his wife, Nancy, moved to their home outside of Urbana, Illinois, it looked a lot different.
2021-10-12 - This edition of Beckman's Grad Student Visionaries series features Elizabeth Bello, a graduate student studying entomology at the University of Illinois Urbana-Champaign. She takes advantage of Beckman’s Microscopy Suite to further her research in the Alleyne Bioinspiration Co-...
2021-10-12 - Animals can influence their offspring through multiple signals starting from fertilization to after birth. However, researchers have seldom looked at how these different signals work together to influence behavior. In a new study, postdoctoral researcher Jennifer Hellmann in the Bell Lab investigated how changes in sperm and paternal care...
2021-10-07 - It’s early morning, about 6 a.m. A light fog has settled over the marsh. I park my car, step out and double-check my backpack for all the necessary equipment before heading out. After a short walk on a narrow paved path, I veer into the unmarked marsh. Water pools around my muck boots and a cacophony of bird calls rings in my ears. In the distance, I see a waving band of neon pink – a flag...
2021-10-06 - The U.S. Department of Agriculture (USDA) has announced funding for a new project led by iSEE Interim Director Madhu Khanna to optimize design for “agrivoltaic” systems — fields with both crops and solar panels — that will maintain crop production, produce renewable energy, and increase farm profitability.
2021-09-30 - Eye size likely plays a role in the contest between avian brood parasites – birds that lay their eggs in the nests of other species – and their hosts, who sometimes detect the foreign eggs and eject or abandon them, scientists report in the journal Biology Letters.
2021-09-07 - At first glance, Trelease Woods looks like any other central Illinois woodland. There’s a well-worn track inside its fenced eastern edge, and the forest floor is littered with twigs and branches. But as I walk along the path with my companions, I notice that some of the trees are bigger than any I’ve seen in this area.
2021-08-25 - Scientists have developed and deployed a series of new imaging and machine-learning tools to discover attributes that contribute to water-use efficiency in crop plants during photosynthesis and to reveal the genetic basis of variation in those traits.
2021-08-24 - It’s a sweltering summer afternoon. I’m pushing aside tree limbs and crunching leaves to get back to the trap that I baited two hours ago with dry ice to attract ticks. When I get closer, I can see a gossamer mist hovering over a bright white cloth in the dark underbrush. Dry ice “sublimates” in the open air, going from a solid to a gaseous state. It gives off a vapor of carbon dioxide gas that’s...
2021-08-19 - A team from the University of Illinois has developed a model that treats photosynthesis as a dynamic process rather than an activity that either is or is not happening.
2021-07-29 - Dozens of online videos document an unusual behavior among tufted titmice and their closest bird kin. A bird will land on an unsuspecting mammal and, cautiously and stealthily, pluck out some of its hair.
2021-07-23 - The Fortuna Hydrological Reserve hosts one third of Panama’s tree species, a variety of fungi waiting to be discovered and a great potential to offset global warming
2021-06-29 - The future of parasitic birds, which lay their eggs in other nests, is totally dependent on their hosts' ability to adjust to climate change. Imagine it’s spring in the year 2048. A Common Cuckoo returns from Africa to her breeding grounds in Europe, just as her ancestors have for thousands of years—except that lately the species has arrived earlier.
2021-06-22 - Researchers at University of Illinois and City University of New York have recently carried out a study investigating the effects of early acoustic experiences on gene activation in songbirds. Their paper, published in Elsevier's journal Neuroscience Letters, shows that the early exposure to salient acoustic...
