Hope for salamanders? Illinois study recalibrates climate change effects
URBANA, Ill. – For tiny salamanders squirming skin-to-soil, big-picture weather patterns may seem as far away as outer space. But for decades, scientists have mostly relied on free-air temperature data at large spatial scales to predict future salamander distributions under climate change. The outlook was dire for the mini ecosystem engineers, suggesting near elimination of habitat in crucial areas.
Now, University of Illinois researchers are tuning into the microclimates that really matter to the imperiled amphibians and forecasting a somewhat more hopeful future.
New grant to reveal tillage effects on crop yield, farmland sustainability
URBANA, Ill. – Researchers from the Agroecosystem Sustainability Center (ASC) at the University of Illinois can detect soil tillage practices from space, weaving together data from ground images, airborne sensors, and satellites.
Study forecasts tile drainage and crop rotation changes for nitrogen loss
URBANA, Ill. – Midwestern agriculture contributes the vast majority of nitrogen in the Gulf of Mexico, causing an oxygen-starved hypoxic zone and challenging coastal economies. State and federal policies have tried for decades to provide solutions and incentives, but the hypoxic zone keeps coming back. A recent study from the University of Illinois offers a new way to understand Midwestern nitrogen dynamics and forecasts future nitrogen loads under various management scenarios across the region.
Deer protected from deadly disease by newly discovered genetic differences
URBANA, Ill. – It was the height of summer 2022 when the calls started coming in. Scores of dead deer suddenly littered rural properties and park preserves, alarming the public and inconveniencing landowners. According to officials at the Urbana Park District, it was Epizootic Hemorrhagic Disease (EHD), a midge-borne viral illness that pops up in white-tailed deer populations around the state every few years.
Reign of invasive rusty crayfish may be ending; Wisconsin lakes rejoice
URBANA, Ill. – Just how hard should natural resource managers fight invasive species after they establish? A new University of Illinois study suggests some invaders – even highly successful ones – can die off naturally, leaving native communities to rebound with minimal management effort.
Why are muskies the fish of 10,000 casts? Illinois study explains
URBANA, Ill. – For anglers, landing a muskellunge, or muskie, is a big deal. The “fish of 10,000 casts” is notoriously elusive, making the massive fish an even bigger prize when one finally strikes a lure.
In a new study, University of Illinois researchers got into the minds of muskies to learn what personality traits make the fish more likely to strike. In the process, they learned valuable lessons that could help conserve the important aquatic predators.
Camera-trap study provides photographic evidence of pumas' ecological impact
CHAMPAIGN, Ill. — A camera-trap study of two ecosystems – one with pumas and one without – adds to scientists’ understanding of the many ways apex predators influence the abundance, diversity and habits of other animals, including smaller carnivores.
Reported in the journal Ecosphere, the study followed multiple members of the order Carnivora, looking at how the largest carnivore in each locale influenced the behavior and presence of other animals in the same vicinity.
From ground to air to space: Tillage estimates get tech boost
URBANA, Ill. – According to national USDA statistics, no-till and conservation tillage are on the rise, with more than three quarters of corn and soybean farmers opting for the practices to reduce soil erosion, maintain soil structure, and save on fuel. However, these estimates are based primarily on farmer self-reporting and are only compiled once every five years, potentially limiting accuracy.
New paper offers best practices for LGBTQ+ field scientists and mentors
URBANA, Ill. – People from marginalized gender and sexual identities can have safer experiences participating in ecological field research when leaders incorporate better field safety protocols and advocate for systemic changes, according to a new paper authored by scientists from Earlham College, the University of Illinois Urbana-Champaign (UIUC), and other institutions.
NCSA supercomputers and ACES researchers fight climate change
A team of researchers at the Agroecosystem Sustainability Center (ASC) at the University of Illinois Urbana-Champaign have been working to make it easier to calculate carbon credits for farmers.
