  • Higher soil temperatures this winter foretell potential crop pest problems

    Winter 2023-24 has been warm throughout Illinois, creating conditions ripe for insects to overwinter, according to scientists at the Prairie Research Institute (PRI) at the University of Illinois.  

  • High water may affect migrating wildlife

    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.

    The entire article can be read on the NewsBank site with subscription access: High water makes habitat harder to find.

  • Historic numbers of waterfowl in the Illinois River Valley

    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.

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

    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).

  • How are Illinois birds faring?

    According to a new study reported in the journal Science, bird populations in North America have experienced a troubling decline in the past five decades. The scientists estimate the continent has lost close to 3 billion birds, roughly 29% of their total numbers in 1970.

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.

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

    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 Birds: A Century of Change receives more attention

    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."

Most notably, Barbicambarus have unusual bearded antennae; the antennae are covered with a luxurious fringe of tiny, hair-like bristles, called setae, which enhance their sensory function. The article has been picked up by Reuters and has spread to news sites everywhere including New ScientistDiscovery NewsYahoo NewsChristian Science MonitorEureka, and Science Blog.

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

    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 BlogScience Codex, and Earth Times.

  • INHS botanists train volunteers at Midewin

    INHS botanists (Rick Phillippe, Paul Marcum, Brenda Molano-Flores, Jason Zylka, Jamie Ellis, and Mary Ann Feist) conducted a one-day vegetation monitoring workshop at the Midewin National Tallgrass Prairie, Will Co. Illinois May 19, 2009. A total of 16 volunteers attended the training. The ultimate goal of the workshop was to give volunteers real life experience in quantitative vegetation data collection and analysis. During the morning, volunteers were shown how to set up transects and plots and to determine percent cover for species and functional groups. During the afternoon, volunteers learned how to analyze and interpret the data they had collected. Volunteers expressed that knowing the dos and don’ts of collecting field data will be extremely helpful when they assist Midewn staff during vegetation sampling. They also commented that, although somewhat overwhelming, they now know how the data they will collect will be used to make management recommendations at the site. This event was sponsored by the Nature Conservancy and the Midewin National Tallgrass Prairie.
