  • 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.

  • 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.

  • 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. 

  • Free workshops give adults a chance to learn to hunt game, waterfowl

    A new program developed by the Illinois Natural History Survey with support from the Illinois Department of Natural Resources aims to encourage more adults to hunt.

    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.

  • 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.

  • 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.

  • Researchers survey and study mosquito vectors for the Zika virus in Illinois

  • Survey finds farmers feel responsibility to protect land and waters

    Agricultural producers are typically blamed for applying fertilizer that pollutes local waters and carries oxygen-depleting nitrogen and phosphorus to the northern Gulf of Mexico. However, a strong majority of Illinois farmers believe they are doing their part to protect the environment, according to a study from the University of Illinois’ Prairie Research Institute (PRI).

  • 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.
