  • 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.

  • Adaptability of deer ticks back in the limelight

    INHS Wildlife Veterinary Epidemiologist Nohra Mateus-Pinilla and her research on lyme disease vectors were featured in an article in the Danville Commercial News and also discussed in a segment on Chicago Tonight about Science in Illinois. Deer ticks have been spreading and are now found in 26 Illinois counties. Mateus-Pinilla's study at Allerton park showed high numbers of infected individuals in prairie habitats, rather than the typical forest habitat. Based on the study, it appears that Lyme disease and deer ticks may be more adaptable than previously known. With regards to the lack of studies on ticks and lyme disease, Mateus-Pinilla said, "There are a lot of unknowns. It seems like we have very little work on the ground being done."

  • Alexandra Cousteau visits Great Rivers Field Station

    Alexandra Cousteau, granddaughter of oceanographer Jacques-Yves Cousteau and founder of Blue Legacy International, visited the National Great Rivers Research and Education Center (NGRREC) in Brighton, IL from April 20 - 22. Cousteau, was gathering film footage for her upcoming documentary, "Expedition: Blue Planet." Ms. Cousteau worked with John Chick, Field Station Director for the INHS and NGRREC, to investigate nutrient-pollution in the Mississippi River due to current farming practices and other sources. To facilitate the learning process for the documentary crew, Dr. Chick also organized a round table discussion for the "Expedition: Blue Planet" group. The round table included representatives from the USDA-NRCS, USEPA, the Nature Conservancy, the Sierra Club and the US Army Corps of Engineers. Dr. Chick and his INHS/NGRREC crew took the Blue Planet Expedition to film on the Mississippi River in various locations, focusing on both healthy sections of this floodplain ecosystem and areas challenged by industrial and agricultural pollution. Expedition members also learned first hand about the risk posed to boaters from the leaping behavior of invasive Asian Carp. Dr. Chick was mentioned in three of the "Expedition: Blue Planet" daily blogs, and was interviewed for the documentary film. Videos from this visit should be posted on the Blue Legacy website in a few weeks.

  • 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.

  • 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."

  • Beware of Climate Neoskepticism

    Skepticism and uncertainty should not excuse inaction in protecting the environment from human-caused climate change, say scientists in a new essay published in the journal Science on August 12.

  • 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.

  • Brian D. Anderson retires from PRI

    On July 8 Prairie Research Institute staff and supporters gathered to bid a fond farewell to Brian D. Anderson, who retired from PRI at the end of June after serving as director of the Illinois Natural History Survey and interim director of PRI.

  • 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.

  • Cat disease Toxoplasmosis found in muskrats and minks

    INHS Graduate student Adam Ahlers led a study on the prevalence of Toxoplasmosis, a disease spread by cats. The researchers found antibodies for Toxoplasma gondii, the parasite that causes toxoplasmosis, in 18 of 30 muskrats and 20 of 26 minks tested for the disease in central Illinois.

  • Cats pass disease to wildlife, even in remote areas

    INHS Wildlife Veterinary Epidemiologist Nohra Mateus-Pinilla and graduate students Shannon Fredebaugh recently published a study that found that even in remote parts of a natural area, cats spread disease to wildlife. Their study, Allerton Park in Monticello, does not have bobcats which strongly suggests feral house cats are responsible for spreading the feline dependent Toxoplasma gondii parasite.  Infection by the parasite causes neurological problems and possible death in humans and other animals. "If one infected cat defecates there, any area can become infected," Fredebaugh said. "It just takes one cat to bring disease to an area."

  • Cave microbe produces compound that inhibits the fungus that causes white-nose syndrome

    A new study from INHS Mycologist Andrew Miller and grad student Daniel Raudabaugh has found that the yeast Candida albicans produces a compound: trans, trans-farnesol, that inhibits growth of Pseudogymnoascus destructans, the fungus that causes white-nose syndrome in bats.

  • Champaign County confirms West Nile in samples

    Richard Lampman, an INHS entomologist, was interviewed by the Daily Illini about West Nile's appearance in Champaign County. Lampman said that this summer's hot, dry weather was perfect for the spread of mosquitoes.
