  • Disease-carrying coastal tick established in Illinois

    Researchers at the Illinois Natural History Survey and Southern Illinois University have new evidence of the Gulf Coast tick becoming established in Illinois. They also have found that it often harbors a pathogen that can make people sick. 

  • Assessment of Asian carp in Illinois waterways

    Scientists and policymakers have long struggled with managing Asian carp numbers in Illinois waterways. PRI's Joe Parkos and Steve Butler explain what's working to scale back these intruders as they inch toward the Great Lakes.

  • Research team examines incubation temperatures for robin eggs

  • Scientists foretell the fate of Illinois’ threatened and endangered plants in a changing climate

    Scorching summers are predicted for Illinois’ future, threatening already vulnerable plant species. University of Illinois scientists have presented a new way to prioritize restoration efforts, not necessarily focusing on the most precarious plants.

  • Exploring personality effects in largemouth bass

    INHS studies have shown that largemouth bass have distinct personalities and that these different types affect predator-prey interactions and possibly habitat use. The explorers tend to have a relatively indiscriminant diet, consuming any prey they encounter, while non-explorers discriminate in their diet selections, focusing on the most profitable prey items. 

  • Chronic wasting disease in Illinois: resources and disease dynamics

    Protecting the deer herd from chronic wasting disease has economical value to the State of Illinois, recreational value to deer hunters, and a health value for CWD-susceptible animals. Currently, there is no treatment or vaccination against CWD. Management based on removal of infected deer in areas where disease is present is the only known strategy to control the spread of CWD.

  • Owls eat roadkill, research finds

    Owls have never been known as scavengers that eat decaying flesh, but the behavior is more widespread than once believed, according to University of Illinois researchers at the Illinois Natural History Survey (INHS) who photographed owls scavenging in the night.

  • Zebra finch study finds mixed impact of early-life stress

    A bout of early-life stress can have lifelong impacts on two key signals that help male zebra finches attract mates: beak color and song complexity. But rather than being uniformly negative, a recent study published in Functional Ecology found that the consequences of stress are mixed. Stressed males wind up with duller, less colorful beaks but sing more complex songs.

  • Turning the tables: Application of commercial fishing helps fight the spread of Asian carp

    The Illinois Department of Natural Resources (IDNR) is using federal funding from the Great Lakes Restoration Initiative to help Illinois’ commercial fishermen suppress the exploding invasive carp population. The project—which brings together multiple agencies and Illinois universities, including the Illinois Natural History Survey and the University of Illinois—is a complex undertaking involving the newest technology in bubble, sound, and electric barriers and fish-counting sonar, coupled with centuries-old stalwarts such as gill nets.

  • Recent surveys find few of once-common bat species

    Bat species that used to be common in Illinois are scarce in recent surveys, sending up a red flag.

  • Researchers suspect that nightjars are declining in Illinois

    Although the Eastern Whip-poor-will is rarely seen, its distinct call occasionally can be heard in forests from dusk until dawn. Once common, Whip-poor-wills and other nocturnal nightjar species are disappearing from Illinois forests as their habitats shrink and change, according to data from the Illinois Natural History Survey (INHS), a division of the University of Illinois’ Prairie Research Institute.

    Eric Schauber, an animal ecologist currently at Southern Illinois University Carbondale, has been selected as the next director of the Prairie Research Institute’s Illinois Natural History Survey. Schauber will begin his appointment on July 1, 2018.

  • Bass learn from experience not to take the bait

    Largemouth bass apparently don’t learn to avoid fishing lures from other bass but instead from their own past experiences, according to University of Illinois research.

  • Survey shows species of marsh birds that decline when nearby cities thrive

    Wading into the springtime muddy marshland, pushing aside a wall of plants taller than her head, ornithologist Anastasia Rahlin looks and listens for signs of black terns and yellow-crowned night herons. She plays a recording, waits 30 seconds, and listens for a return call. The species of birds that she doesn’t find in the marsh are the ones she doesn’t want scientists to forget.

  • Brown Marmorated Stink Bugs are on the Move This Fall

    An invasive stink bug species has been found in five newly invaded Illinois counties this year, according to Kelly Estes, Cooperative Agricultural Pest Survey (CAPS) coordinator in the Prairie Research Institute, University of Illinois.

  • Researchers rescued stranded mussels on the Vermilion River

  • Researchers describe crayfish conservation concerns and strategies

    Whether you call them crayfish, crawfish, or crawdad, this creature needs protection nationwide to prevent extinction, according to Chris Taylor, Illinois Natural History Survey curator at the University of Illinois. In a recent article published in the journal Hydrobiologia, Taylor and colleagues have outlined possible strategies for conservation practices to protect crayfish from invasive species, habitat changes, and potential overexploitation.

  • The best laid plans: Did insect resistance management hasten Bt resistance in western corn rootworm?

    Illinois Natural History Survey scientists studied behaviors of the western corn rootworm to learn why the insect pests have developed a resistance to Bt corn hybrids, once a deterrent that was as effective as soil insecticides but without the human health risks and environmental concerns associated with broad-spectrum insecticides.

  • Scientists Debunk Myths about Illinois Bats

    Bats, long associated with Halloween and tales of horror, have far more to fear from humans than we do from them. Researchers at the Illinois Natural History Survey (INHS), Prairie Research Institute, monitor bats statewide by capturing, identifying, and banding individuals in fine-meshed netting (mist nets) and collecting acoustic recordings of high-frequency bat calls.

  • Carp play a role in disseminating plant seeds in the Illinois River

  • Digitization Projects Make Nature Collections Available to Everyone

    Extinct feather lice, invasive fish from the Great Lakes, and rare plants from Pakistan are a few of the millions of species no longer viewed just in dark academic warehouses and museums. Curators at the Prairie Research Institute (PRI) who have helped to preserve these biological specimens are digitizing them for anyone who is interested in science to view them online.

  • INHS Reports: Fighting the spread of aquatic invasive species in the marketplace

    Aquatic invasive species are non-native organisms that harm the environment, economy, or human and livestock health. Illinois is especially vulnerable to aquatic invaders. Harmful effects of aquatic invasive species that reside in the lake include the multimillion dollar annual cost to industry and water utilities, reduced recreational activities, and degrading native habitats. One way that aquatic invaders are introduced to the Great Lakes region is through the buying and selling of species.
