  • Endangered mussels released in Illinois streams

    Sep 10, 2012 8:00 am

    Endangered riffleshell and clubshell mussels collected in Pennsylvania earlier this summer have begun being relocated into Illinois Rivers. The mussels were placed, one by one into the gravel of their new stream. Each mussel has a rice sized transponder attached to its shell to identify it, enabling scientists to non-invasively monitor their progress in their new environment.

  • End to live turtles in the Turtle Races

    Jun 19, 2013 8:00 am

    For the past 49 years, box turtles have been collected from the wild and brought to Danville for the annual Turtle Reunion and Races, a charity event. This has been a concern to herpetologists, including INHS Herpetologist Chris Phillips and U of I Wildlife Veterinarian Matt Allender (an INHS Affiliate), for several reasons including the possibility of spreading diseases. The two scientists have been collaborating on a long term study of the health of box turtles in Vermilion County. They have been testing for diseases including ranavirus, a contagious disease with high mortality that is also a threat to amphibians.

  • Engineering students help INHS researchers

    Aug 6, 2012 8:00 am

    INHS researchers tapped into the innovative nature of engineering students to design systems that would help address questions about North American River Otters. As part of their senior design projects, 4 groups of students set out to tackle different problems. One device, the Otter Print Shooter, is a pressure and motion sensitive camera encased in clear box, under ground. When an otter steps on the box, the print shooter takes a photo of the paw. Otter paw prints are believed to have unique patterns, similar to fingerprints. The Otter Stalker System wirelessly connects multiple trail cameras, thereby increasing the field of view, allowing the researchers to capture more of the behavior of river otters.

  • Exploring personality effects in largemouth bass

    Nov 16, 2017 10:00 am

    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. 

  • 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.

  • Few hunters know how their duck stamp dollars are spent

    Oct 6, 2017 9:15 am

    Illinois hunters each pay $25 for an annual federal duck stamp to legally shoot waterfowl, yet few know how their money is used, according to a University of Illinois study.

  • Fig wasps older than known fig trees

    Jan 17, 2014 8:00 am

    INHS Paleontologist Sam Heads found an ancient fig wasp that pre-dates any known fig trees. According to Heads, “This is a tiny parasitic wasp, it's the smallest fossil wasp found in this particular deposit and it's the oldest representative of its family. More importantly, it’s possible that this wasp was fig-associated, which is interesting because it’s Early Cretaceous, about 115 to 120 million years old. That's a good 65 million years or so prior to the first occurrence of figs in the fossil record.”

  • 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.

    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.

  • First comprehensive treatise on leafhopper genus Zyginama published

  • Fish Quality Index a "potential game changer"

    Jun 2, 2014 8:00 am

    Project F-69-R, also known as the “Sport Fish Population and Sport Fishing Metric” project, is developing a Fish Quality Index that will help fisheries biologists evaluate and compare the quality of sport fishing for various species in different water bodies. The collaborative project is headed by INHS Sport Fish Ecologist Jeff Stein. This information can be used to inform anglers of the best places to catch a particular species and to help fisheries biologists manage those species. Read more about Project F-69-R and the Sport Fish Ecology Lab's research projects.

  • Forests help shield streams from pollutants in cropland areas

    Sep 16, 2019 10:00 am

    Streambank forests that help to buffer streams from pollutants are particularly important for stream quality, even in areas such as east-central Illinois where cropland predominates and the river system has deteriorated, according to a University of Illinois study.

  • 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.

  • Fossil Insect Collaborative kicks off

    Jul 9, 2013 8:00 am

    INHS Entomologist Sam Heads is part of a collaborative effort to digitize fossil insect collections across the country.

  • 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."

  • 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.

  • 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.

    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

    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.

  • 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).
