  • Illinois Birds: A Century of Change receives more attention

    Mar 28, 2011 8:00 am

    Co-author Mike Ward was interviewed by the Chicago Tribune about the recently published "Illinois Birds: A Century of Change." Mike Ward said that the results of the most recent studies were somewhat encouraging. "There's definitely reason to be concerned for certain species of birds, but I don't think we're at the worst point in the last 100 years. I think the worst point was definitely somewhere between the 1950s and now, when our waters were really contaminated and there was a wider use of nasty pesticides. There's reason for concern today, but on the flip side there are definitely triumphs."

  • Illinois Birds: A Century of Change applauded by USFWS and IDNR

    Jan 4, 2011 8:00 am

    The US Fish and Wildlife Service and the Illinois Department of Natural Resources put out a press release praising the most recent INHS Special Publication. “This book demonstrates the importance of investing in long-term research to provide the information needed by natural resource managers to make wise, science-based resource management decisions.  It also emphasizes the importance of public-private, and state-federal partnerships in responding to landscape scale natural resource challenges,” said Marc Miller, Director of the Illinois DNR. “The long term data collected by these surveys provides the information necessary to evaluate changing bird distributions,” said Tom Melius, Midwest Regional Director of the Service. "Illinois Birds: A Century of Change is a benchmark in bird research that will inform current and future bird conservation priorities, and serve as a model for bird research across the United States.” The book was also reviewed in the Rockford Register Star, the BirdBooker Report and the Herald Review.

  • Illinois armadillo sightings becoming more frequent

    May 20, 2008 11:00 am

    Dr. Joyce Hofmann discusses the possible reasons for more frequent armadillo sightings in Illinois in the May 16, 2008 On-line edition of the Journal Gazette Times-Courier. Dr. Hofmann has been keeping track of the sightings since 1999 for a manuscript she is compiling. She says that the animal, which is abundant southern Missouri, began to be sighted Southern Illinois during the late 1970s. To read the Journal Gazette article in its entirety, visit this website.

    Jul 20, 2021 10:00 am

    According to a new report co-written by Illinois Natural History Survey postdoctoral researcher Valeria Trivellone, climate change, poverty, urbanization, land-use change and the exploitation of wildlife all contribute to the emergence of new infectious diseases, which, in turn, threaten global food security. Trivellone spoke with News Bureau life sciences editor Diana Yates about how global authorities can tackle these intertwined challenges.

  • Hospitable Illinois wetlands in spring signal happy waterfowl hunting in fall

    Feb 23, 2017 8:00 am

    When waterfowl return to Illinois in early spring on their way north, will they find enough food for a two-week layover? A limited food supply during spring migration and subsequent declines in duck populations can affect Illinois’ multi-million-dollar waterfowl hunting industry, say researchers from the University of Illinois’ Prairie Research Institute (PRI).

  • Historic numbers of waterfowl in the Illinois River Valley

    Jan 6, 2014 8:00 am

    INHS researchers at the Forbes Biological Station recorded the historic numbers of waterfowl this year in the Illinois River Valley. At migration’s peak, 329,590 mallards were counted, the highest number since 1999. Northern pintails (141,840), green-winged teal (179,620), gadwall (146,300) and northern shovelers (49,060) were present in the highest numbers since the survey began.

  • High water may affect migrating wildlife

    Jul 14, 2009 4:15 pm

    An article in the July 10, 2009 edition of the "The Courier" (Lincoln, IL) written by Chris Young talks about the effect that the wet summer could have on Illinois plants and the migratory species that pass through IL in the autumn.

    Randy Smith, an INHS scientist at the Forbes Biological Field Station, says that the weeds that migrating species need may not be able to grow if the water levels don't recede. Without food for migrating animals, they might not stop over in Illinois.

  • 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.

  • Freshwater mussels: overlooked and under appreciated

    Aug 10, 2011 8:00 am

    Environmental Almanac writer Rob Kanter wrote "Freshwater mussels: overlooked, under appreciated residents of Illinois streams" earlier this month, referencing the INHS publication Field Guide to Freshwater Mussels of the Midwest. Malacologist Kevin Cummings was consulted for the post and reported that North America has the greatest diversity of freshwater mussels, with nearly three hundred species and subspecies. Illinois is/was home to eighty of these species, but only about half of them are currently found with regularity.

  • Freshwater mussel behavior altered by exposure to antidepressants

    Jan 10, 2014 8:00 am

    INHS Post-doctoral researcher Andrea Fritts is a co-author on a recently published study examining the effects of the antidepressant fluoxetine on the behavior of freshwater mussels, which could impact their survival and role in their ecosystem. The study found that chronic exposure led to "increases in movement, decreased time to movement, and increased likelihood of diurnal movement, and increased rates of lure display in mussels. Changes in mussel movement [in the wild] are likely to increase susceptibility to predation, and may also alter sediment nutrient cycling and oxygenation through changes in bioturbation provided by mussels."

The project officially kicked off the 1st of July, 2013.

  • Eastern massasauga rattlesnake

    For now, Illinois’ imperiled eastern massasauga rattlesnakes retain their genetic diversity

    Aug 13, 2018 9:15 am

    Habitat loss, habitat fragmentation and the loss of genetic diversity are the three main factors driving the extinction of many wild species, and the few eastern massasauga rattlesnakes remaining in Illinois have certainly suffered two of the three. A long-term study of these snakes reveals, however, that – despite their alarming decline in numbers – they have retained a surprising amount of genetic diversity.

    Fire-spawned forest fungi hide out in other organisms, study finds

    Oct 25, 2019 6:45 am

    When a wildfire obliterates a forest, the first life to rise from the ashes is usually a fungus – one of several species that cannot complete its life cycle in the absence of fire. Scientists have long argued about where and how such pyrophilous (fire-loving) fungi survive, sometimes for decades, between fires. A new study finds that some of these fungi hide out in the tissues of mosses and lichens.

  • Finding darters where no one thought to look

    Nov 29, 2018 11:45 am

    INHS staff spent the last two summers sampling small, overlooked streams throughout much of the greater Chicago region and discovered that the Iowa darter has been hiding out in streams so small that biologists haven’t bothered to sample them. It appears that there are enough healthy populations in these small streams that this fish is in the process of being taken off the state threatened-species list.
