  • Emerald ash borer quarantine area expanded

    The Cooperative Agricultural Pest Survey program posted that Champaign and Vermilion Counties have been added to the Emerald Ash Borer Quarantine Area.

  • Emiquon producing massive crappie

    INHS Fisheries Technicians Kenny Lookingbill (sunglasses at right) and Collin Hinz (left), reported that recent fish surveys at Emiquon turned up massive crappies, the largest weighing in at 3.4 pounds, 17 inches long. Emiquon is an approximately 3,000 acre restored natural area along the Illinois River and based on these surveys may become the best crappie fishery. INHS Illinois River Biologial Field Station and the INHS Forbes Biological Field Station study the waterfowl and fish populations in that area as a means of evaluating the success of the restoration and management.

  • Endangered bumblebees to be counted and studied this summer

  • Endangered mussels released in Illinois streams

    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

    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

    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.

  • Entomologists stifled by Indian bureaucracy

    An international collaboration to study insects in the Western Ghats mountains in southern India is stalled due to a hold up by the National Biodiversity Authority (NBA). INHS' Paul Tinerella and Michael Irwin are involved in trying to keep the project moving along. View the complete Nature article

    Eric Schauber to helm Illinois Natural History Survey

    Eric Schauber, an animal ecologist currently at Southern Illinois University Carbondale, has been selected as the next director of the Prairie Research Institute’s Illinois Natural History Survey. Schauber will begin his appointment on July 1, 2018.

  • Exploring personality effects in largemouth bass

    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

    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

    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

    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

    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.

  • plants and fungi

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

    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

  • First fossil of differential grasshopper described

    INHS Paleo-entomologist Sam Heads and collaborator Yinan Wang recently described the first fossil record of the differential grasshopper. The specimen, a species which is still alive today, was found in material from the Late Pleistocene McKittrick tar pits of southern California.

  • Fish Quality Index a "potential game changer"

    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

    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

    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

    INHS Entomologist Sam Heads is part of a collaborative effort to digitize fossil insect collections across the country. The Fossil Insect Collaborative is a joint venture between the Virginia Museum of Natural History (VMNH), the American Museum of Natural History, the Yale Peabody Museum, the Museum of Comparative Zoology at Harvard, the University of Colorado, the University of Illinois, and the University of Kansas. The project officially kicked off the 1st of July, 2013.

  • Four-leaf clover: Rare variation of a common, edible weed (and may be good luck)

    INHS Botanist Greg Spyreas was interviewed for an article about four-leaf clovers. He explained that it is a developmental anomaly and couldn't attest to its luckiness. Having found a four-leaf clover once may or may not explain that his "whole life has been good luck.”

  • Fowl flocking to Emiquon

    According to the latest aerial inventories there were 63,225 ducks at Emiquon on Oct. 17. At the same time last year there were 50,775 ducks. Emiquon is a 6,900 acre Nature Conservancy reclamation along the Illinois River, established in 2005.

  • Free workshops give adults a chance to learn to hunt game, waterfowl

    A new program developed by the Illinois Natural History Survey with support from the Illinois Department of Natural Resources aims to encourage more adults to hunt. The Hunter Recruitment Program is offering a series of free workshops around the state, giving new hunters an opportunity to learn from experienced mentors and to get hands-on experience hunting for deer, turkey, squirrels, pheasants, ducks, geese and other game.

  • Freshwater mussel behavior altered by exposure to antidepressants

    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

    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.

  • bluegill fish

    Friendlier fish may be quicker to take the bait

    The bluegill on your dinner plate might have been more social than the rest of its group, according to a new study from the University of Illinois, and its removal from the lake could mean major changes for the remaining population.

  • Fungus that causes white nose syndrome is a survivor

    INHS Mycologist Andrew Miller and graduate student Daniel Raudabaugh recently published a paper on the fungus Pseudogymnoascus (Geomyces) destructans, which causes white nose syndrome in bats. In this first, in depth study of the basic biology of the fungus, the researchers found that P. destructans can survive on a wide variety of nutrient sources.

  • Greater Prairie Chickens can't endure without human help

    Researchers at the Illinois Natural History Survey report that the greater prairie chicken cannot persist in Illinois without help.

  • Hear the Sound of Owls Calling at Night

    “Birds of omen, dark and foul,” wrote Sir Walter Scott about owls, once considered harbingers of doom, death, and destruction. In Medieval Europe, owls were thought to be witches and an owl's call meant someone was about to die.

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

    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.

  • Herbivores play important role in protecting habitats from invasive species

    Researchers from the Illinois Natural History Survey and the Morton Arboretum have been examining the potential role of herbivores on the invasion of non-native plant species in diverse plant communities.

  • Herons persist in Chicago wetlands despite exposure to banned chemicals

    Results of a study led by INHS wildlife toxicologist Jeff Levengood were published in the latest issue of the Journal of Great Lakes Research. The study reports that Chicago-area herons are still being exposed to banned pesticides.

  • 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.

  • Valeria Trivellone

    How can the world prevent emerging infectious diseases, protect food security?

    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.

  • Illinois armadillo sightings becoming more frequent

    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.

  • 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."
