  • 1000 more endangered mussels released in Illinois rivers

    Over the course of a week, 1000 endangered mussels were collected from under a bridge construction site in Pennsylvania, packed for safe transport, quarantined, marked, measured, and released into new sites in Vermilion County, Illinois. This is the third relocation from Pennsylvania to Illinois as part of the Species Survival Plan for two endangered mussels, the northern riffleshell and the clubshell. Read the entire story from the U of I News Bureau, INHS, and the News Gazette.

  • A spotted turtle in water

    30 years of data show spotted turtle communities are still vulnerable

    Populations of the endangered spotted turtle in Illinois are holding up better than those in other states, based on 30 years of data at the University of Illinois. Still, only two populations remain, and the predictions are poor.

  • assassin bug fossil

    50 million-year-old fossil assassin bug has unusually well-preserved genitalia

    The fossilized insect is tiny and its genital capsule, called a pygophore, is roughly the length of a grain of rice. It is remarkable, scientists say, because the bug’s physical characteristics – from the bold banding pattern on its legs to the internal features of its genitalia – are clearly visible and well-preserved. Recovered from the Green River Formation in present-day Colorado, the fossil represents a new genus and species of predatory insects known as assassin bugs.

  • Arsenic, mercury and selenium in Asian carp not a health concern to most

    A recent study by INHS researchers Jeffrey M. Levengood, David J. Soucek, Gregory G. Sass, Amy Dickinson, and John M. Epifanio showed that overall, concentrations of arsenic, selenium, and mercury in bighead and silver carp from the lower Illinois River do not appear to be a health concern for a majority of human consumers. The full results of the study have been published in the journal Chemosphere.

  • Asian Carp barrier catches turtle

    A barrier designed to prevent Asian Carp from reaching Lake Michigan had the unintended consequence of catching a snapping turtle. This was the first known instance of an animal trapped in the mesh and the turtle was released unharmed. When first installed, migrating turtles were completely blocked by the carp barrier. Subsequent gates installed along the length of the barrier allow turtles to migrate through. The location of the gates was based on the multi-year radio telemetry study conducted by INHS herpetologists on the endangered Blandings' Turtle and other turtles in the area.

  • Asian carp still doing well

    Thad Cook, of the Illinois River Biological Station, took an impressive photo of carp that appeared in a web log of the Peoria Journal Star.

  • Asian tiger mosquito

    Asian tiger mosquito gains ground in Illinois

    Researchers report that the Asian tiger mosquito, Aedes albopictus, has become more abundant across Illinois in the past three decades. Its spread is problematic, as the mosquito can transmit diseases–like chikungunya or dengue fever–to humans.

    Assessment of Asian carp in Illinois waterways

    Scientists and policymakers have long struggled with managing Asian carp numbers in Illinois waterways. PRI's Joe Parkos and Steve Butler explain what's working to scale back these intruders as they inch toward the Great Lakes.

  • Attack of the Flying Fish

    The Illinois Times talks to Kevin Irons, INHS LTRMP Fish Specialist, about sampling for Asian carp. Irons catalogs some of the things that he does to make sampling on the Illinois River safe.

  • Bald Eagles "making an impressive comeback"

    INHS Ornithologist Mike Ward was contacted about the increase in eagle sightings in the area. According to Ward, there were fewer than 20 eagle nests in Illinois in the 80s, whereas during the last spring bird count, there were an estimated 200 eagle nests.

  • Bald Eagles nesting in NE Illinois

    The recent discovery of a nesting pair of Bald Eagles in Lake County has been described as "a fairly big deal." According to INHS Ornithologist Steve Bailey, the Chicago area did not have breeding pairs of eagles until recently, and he knew of only one other nesting pair in Lake County. This discovery brings the total to 5 active Bald Eagle nests in the Chicago area this season.

  • Banned chemicals persist in river otters

    INHS researchers Samantha Carpenter and Nohra Mateus-Pinilla recently published a paper in the journal Ecotoxicology and Environmental Safety. Carpenter, Mateus-Pinilla, and University of Illinois Veterinary Diagnostic Laboratory researchers, analyzed liver tissue samples from 23 river otters looking at 20 organohalogenated compounds used in agriculture and industry. Read stories from the Red Orbit and News Room America.

  • Baseline mussel survey finds only one female Fatmucket

    INHS Aquatic Biologist Jeremy Tiemann led a team in a baseline survey of mussels in Crystal Lake Park, finding only a female Fatmucket. The team will return in 5-10 years to see if the planned installation of in-stream riffles improves the habitat and changes the mussel population.

  • Be A Hero - Transport Zero campaign to stop the spread of exotic species wins award

    The Awards for Publication Excellence (APEX) are given each year by Communication Concepts to recognize outstanding publication work in a variety of fields, and one of the Illinois Natural History Survey projects was selected this year for an award. Sarah Zack, Pat Charlebois, and their IL-IN Sea Grant colleague Jason Brown were awarded in the Green Campaigns, Programs & Plans category for their work on our “Be A Hero – Transport Zero” campaign and messaging, and for the www.TransportZero.org website. The campaign is designed to show boaters, fishermen, and other recreational water users how simple it can be to help prevent the spread of aquatic invasive species between water bodies.

  • "Bearded" crayfish species—what else is out there?

    INHS Astacologist Chris Taylor was interviewed by On Earth about the new species of "bearded" crayfish he described earlier this year. He described crayfish as "one of the most important, if not the most important link" between primary producers (which they eat), and predators like fish and birds (which eat them). He added that uncovering a new species in a well studied area "just reinforces the point that we don't know everything about these aquatic ecosystems, and that there are still discoveries to be made."

  • Bitter cold in January likely won’t reduce field crop pests in the spring

    Despite the record cold air temperatures, soil temperatures averaged slightly warmer than normal this winter. Consequently, the Arctic conditions are expected to have little effect on overwintering field crop insect pest populations.

  • cluster of Humboldt penguins on the shoreline

    Blood markers predict Humboldt penguin nest type, reproductive success

    Researchers looked at metabolic markers in the blood of 30 Humboldt penguins nesting in the Punta San Juan Marine Protected Area in Peru, finding that penguins in guano-rich burrows and unsheltered locations had consistent – and distinct – patterns of several sugars in their blood. 

  • Bobwhites nesting in a field of flowers.

    Bobwhites listen to each other when picking habitat

    Northern bobwhites are attracted to a habitat based on whether other bobwhites are present there, research led by Illinois Natural History Survey avian ecologist Michael Ward. This phenomenon, called conspecific attraction, could aid conservation efforts.

  • Boom of record breaking bass over?

    INHS Conservation Geneticist Dave Philipp studied bass for 20 years, finding that genetics plays a role in which fish are caught. Fish that are more aggressive, thus more likely to bite a hook, pass that trait on to their offspring. As those aggressive fish are caught and removed from the population, the remaining fish are genetically harder to catch. This is one of the theories suggested to explain the mystery of why the Pennsylvania Largemouth Bass State Record has stood for nearly 30 years.

  • Brown marmorated stink bug in Illinois

    The Brown Marmorated Stink Bug is a new invasive species being found in Illinois that is getting a lot of media attention. INHS Entomologist Chris Dietrich discussed the bugs in the Geneva Republican, stating that with no natural predators, these bugs can become a nuisance species. He adds that, “They’re actually considered a delicacy in some parts of Mexico.” Illinois Cooperative Agriculture Pest Survey Entomologist, Kelly Estes was interviewed about the bugs on WGLT - Bloomington NPR affiliate and WILL 580. This species has been confirmed in Cook, Kane, Champaign and McLean counties but scientists are still determining the extent of its spread. She asks that if you think you have this (or other pest species) send her a photo or the actual specimen for positive identification. She can be contacted at invasives@inhs.illinois.edu.

  • Brown Marmorated Stink Bugs are on the Move This Fall

    An invasive stink bug species has been found in five newly invaded Illinois counties this year, according to Kelly Estes, Cooperative Agricultural Pest Survey (CAPS) coordinator in the Prairie Research Institute, University of Illinois.

  • Bullfrogs insensitive to road salt

    INHS post doctoral researcher Tanya Hawley Matlaga, INHS Herpetologist Chris Phillips, and INHS Ecotoxicologist David Soucek report that bullfrogs are less sensitive to elevated chloride concentrations than some other amphibian species. The study was designed to mimic the level of salt found in roadside ponds following de-icing events. The study found that bullfrog tadpoles did not experience reduced survival, growth, or ability to evade predation in elevated chloride concentrations, and thus, their populations are not expected to be impacted by road salt. While this is good news for bullfrogs, it's an additional stress for other species inhabiting ponds with these voracious predators.

  • Bumblebee populations declining

    The bumblebee crisis was discussed in a February 21, 2008 post to the North Carolina State University Insect Museum blog. The article discusses what factors are contributing to the bumblebee's decline and mentions research done by Solter labs. Lee Solter is an Associate Scientist and Insect Pathology Research Leader with the Illinois Natural History Survey.

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

    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.
