  • Soil characteristics may be related to chronic wasting disease persistence, study finds

    Feb 5, 2018 3:30 pm

    Deer infected with chronic wasting disease are doomed to a slow and certain death, eventually wasting away as they lose the ability to eat and drink. There is no cure and no vaccine, and the number of infected deer continues to rise every year. But University of Illinois scientists recently published a new study that could help explain the movement of the disease across the landscape.

Using optimization algorithms, historical data on field trapping of mosquitoes and ticks, and other ecological methods, the Illinois team will also help determine the level of surveillance data required to make effective control decisions.

  • INHS botanists reconstruct 226 year history of fire in Southern Illinois

    Mar 14, 2011 4:45 pm

    By looking at the scars in the growth rings of 36 old-growth post oak trees, INHS botanist Greg Spyreas, affiliate John Ebinger and Illinois State Museum botanist William McClain found that there had been more than 100 fires in Southern Illinois between the 1770s and 1996. This repeated burning stabilized prairies and kept the woodlands open until the mid-1800s when fires appear to have been suppressed by the settlers in the area for a 30 year period. Fire suppression altered the plant community by allowing fast-growing, shade-loving species to survive. The study was published in the journal Castanea. Read news coverage of the story by the Science Blog, Science Codex, and Earth Times.

    North ‘plaza’ in Cahokia was likely inundated year-round, study finds

    Jul 21, 2022 8:15 am

    The ancient North American city of Cahokia had as its focal point a feature now known as Monks Mound, a giant earthwork surrounded on its north, south, east and west by large rectangular open areas. These flat zones, called plazas by archaeologists since the early 1960s, were thought to serve as communal areas that served the many mounds and structures of the city.

    New paleoenvironmental analyses of the north plaza suggest it was almost always underwater, calling into question earlier interpretations of the north plaza’s role in Cahokian society. The study is reported in the journal World Archaeology.

  • Study links fish stress hormones to whether they take the bait

    Aug 22, 2017 11:00 am

    Take a fish out of water and its stress hormones will go up. Adrenaline and noradrenaline, the “fight or flight” hormones, peak first, followed more gradually by cortisol. A new study reported in the Journal of Experimental Biology finds that largemouth bass whose cortisol levels rise most after a brief bout of stress are inherently harder to catch by angling. This could affect recreational fishing. If anglers are primarily capturing fish whose stress levels dictate whether they are likely to strike at a lure, “we could potentially be selecting for fish that are harder to catch,” said University of Illinois natural resources and environmental sciences professor Cory Suski, who led the new research with Illinois Natural History Survey research scientist Jeffrey Stein and graduate student Michael Louison.
