  • Few Chicagoland wetlands left without non-native species, study finds

    Feb 23, 2018 12:30 pm

    The wetlands in and around Chicago are overwhelmingly invaded by non-native plants, according to a new study by University of Illinois researchers. The study, which pulls together species occurrence data from over 2,000 wetlands in the urban region, is the first to describe wetland invasion patterns on such a large scale in the Chicagoland area.

  • On the hunt for first flower of spring

    Mar 5, 2010 11:45 am

    Environmental Almanac, written by Rob Kanter, describes searching for skunk cabbage. Kanter, along with INHS Wetland Plant Ecologist Rick Larimore, headed out to the Middle Fork State Fish and Wildlife Area in Vermilion County to see this "first flower" of spring. Kanter and Larimore were successful in their quest to find skunk cabbage. Skunk cabbage is able to bloom so early in the year because it generates enough heat to grow in the frozen ground. It gets it's name from the rotting flesh smell it exudes to attract ground pollinating insects.

  • Morels in Illinois: first steps on the path to a new obsession

    Apr 13, 2012 8:00 am

    Hunting for morels is a popular spring pastime for many. INHS Mycologist Andy Miller was consulted by Rob Kanter for an Environmental Almanac piece and revealed that there are at least 26 separate species of black morels and 16 species of yellow morel. Not mentioning specific locations, Andy gave tips to would-be hunters on where to look, such as moist areas near dead elm trees or living ash trees. Borrowing Rob Kanter's words of warning: Deadly poisonous mushrooms occur along with nonpoisonous ones throughout Illinois. Neither this article nor the accompanying photo is intended to enable beginners to distinguish between them.

    White Nose Syndrome, the fungal disease that leads to mortality in bats, has now been confirmed in 11 counties in Illinois. First discovered in New York in 2006, the fungus has spread west, first being detected in Illinois in 2013. INHS Cave Biologist Steve Taylor told an NPR affiliate that, "between 2013 and 2015, it was like a 95 percent decrease in the number of bats at this site, which in 2013 was in excess of 25,000 bats."

    Jun 4, 2019 12:45 pm

    As foxes and coyotes adapt to urban landscapes, the potential for encounters with humans necessarily goes up. A team of scientists is taking advantage of this fact to enlist the eyeballs and fingertips of humans – getting them to report online what they see in their own neighborhoods and parks.

  • Bumper crop of mosquitoes, but not West-Nile Virus, yet

    Jun 7, 2011 8:00 am

    According to INHS Medical Entomology Director Ephantus Juma Muturi, despite the large number of mosquitoes out now, the level of West-Nile Virus is still very low. The optimal breeding environment for West-Nile Virus bearing mosquitoes is dry, warmer weather, when the larvae are not washed away by heavy rains.

    Ancient katydid fossil reveals muscles, digestive tract, glands and a testicle

    Jun 26, 2023 1:45 pm

    Fifty million years ago in what is now northwestern Colorado, a katydid died, sank to the bottom of a lake and was quickly buried in fine sediments, where it remained until its compressed fossil was recovered in recent years. When researchers examined the fossil under a microscope, they saw that not only had many of the insect’s hard structures been preserved in the compressed shale, so had several internal organs and tissues, which are not normally fossilized. 

  • Osprey being brought back to Illinois

    Jul 12, 2013 8:00 am

    INHS Ornithologist Tara Beveroth is assisting the Illinois Department of Natural Resources as they work to restore osprey populations in Illinois.

INHS Mycologist Andrew Miller and his graduate student Dan Raudabaugh are working to understand the fungus itself. This work is being done in conjunction with the long-term INHS research project on the critically endangered Eastern Massasauga Rattlesnake. INHS Herpetologists Chris Phillips and Mike Dreslik have been studying the ecology of the snakes for over 15 years.

  • Japanese beetles thrive in human landscapes

    Jul 18, 2011 8:00 am

    According to INHS entomologist Chris Dietrich, Japanese beetles are generalists and will eat approximately 300 different types of plants, which is not unusual for an introduced species. Human lawns make perfect habitat for the grubs which feed on the roots of grass, but killing the grubs will do little, as adults will fly in from other yards.

  • West Nile found in Champaign county mosquitoes

    Aug 15, 2011 8:00 am

    INHS Medical Entomology Program confirmed the presence of West Nile Virus in a mosquito sample from the Champaign Department of Public Health. Champaign is the 12th county to have positive mosquito samples this year. No human cases have been reported yet this year, but the CDPH recommends dumping standing water and taking general precautions.

  • Heavy rains wash away mosquito larvae, but mosquitoes repopulate standing waters

    Aug 16, 2011 8:00 am

    Entomologist Rich Lampman was interviewed by Chicago's CBS affiliate WBBM about mosquitoes.  According to Lampman heavy rains in northern Illinois in July may have flushed out larvae in standing water. Unfortunately, any puddles left over will be colonized by new mosquitoes. Dumping standing water every couple of days can help keep mosquito numbers down.

This paper is the first to identify Miscanthus, which is a crop that can be used for biofuels, as a host to corn rootworm. Corn rootworm is estimated to be a billion dollar yearly problem to the United States’ corn industry as the as the corn rootworm damages the plant's roots and leads to a significantly decreased yield.

  • Illinois scientists look for signs of disease that killed millions of bats

    Jan 20, 2012 8:00 am

As a preventative measure, Illinois caves on public lands have been closed to the public since 2010. This winter an interdisciplinary team of INHS researchers will begin surveying caves in Illinois for evidence of White Nose Syndrome, taking tissue, air and soil samples. Their goal is to form a more complete understanding of the cave environment including the fungi, bacteria and other microorganisms present.
