  1000 more endangered mussels released in Illinois rivers

  Sep 4, 2013 8:00 am0 views

  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.

• 2009 William H. Luckmann winner announced

  Mar 11, 2009 1:30 pm5 views

  Nicholas A. Tinsley has won the 2009 William H. Luckmann Award for Research in Applied Entomology. His research project, "Effects of Current and Future Soybean Aphid Management Tactics on Soybean Aphids and Their Natural Enemies in Illinois," will help scientists and growers improve methods of Soybean Aphid integrated pest management. The William H. Luckmann Award is given for research that focuses on aspects of applied entomology such as arthropod pest management, use of insects in biological control programs, pollinators, or natural areas health. The research may be carried out for agricultural, horticultural, urban, medical or natural areas systems. Visit the Illinois Natural History Survey webpage to learn more about the William H.

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

  Jan 19, 2021 10:45 am4 views

  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.

  Adaptability of deer ticks back in the limelight

  Sep 14, 2011 8:00 am0 views

  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

  Apr 24, 2009 10:15 am0 views

  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

  Jun 14, 2012 8:00 am2 views

  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.

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

  May 1, 2011 12:30 pm2 views

  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."

  Boom of record breaking bass over?

  Jun 15, 2012 8:00 am5 views

  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

  May 2, 2011 8:00 am0 views

  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.
