  • Dogs find turtles that researchers can't

    May 24, 2012 8:00 am

    This past week INHS Herpetologist Chris Phillips enlisted the help of a team of 8 dogs to locate box turtles as part of a long term population study. The dogs, Boykin Spaniels, and their handler, John Rucker have helped researchers across the country locate box turtles. The study in Illinois is a collaborative effort between the INHS and the U of I College of Veterinary Medicine to monitor the health and ecology of the box turtle populations in an effort to conserve this species. Their small size, high energy, keen sense of smell and ability to fight through thorns enabled the dogs to out-turtle the humans 42 to 4 this week. They will return in June.

  • INHS botanists train volunteers at Midewin

    Jun 1, 2009 9:30 am

    INHS botanists (Rick Phillippe, Paul Marcum, Brenda Molano-Flores, Jason Zylka, Jamie Ellis, and Mary Ann Feist) conducted a one-day vegetation monitoring workshop at the Midewin National Tallgrass Prairie, Will Co. Illinois May 19, 2009. A total of 16 volunteers attended the training. The ultimate goal of the workshop was to give volunteers real life experience in quantitative vegetation data collection and analysis. During the morning, volunteers were shown how to set up transects and plots and to determine percent cover for species and functional groups. During the afternoon, volunteers learned how to analyze and interpret the data they had collected. Volunteers expressed that knowing the dos and don’ts of collecting field data will be extremely helpful when they assist Midewn staff during vegetation sampling. They also commented that, although somewhat overwhelming, they now know how the data they will collect will be used to make management recommendations at the site. This event was sponsored by the Nature Conservancy and the Midewin National Tallgrass Prairie.

  • 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.

  • Researchers track the secret lives of feral and free-roaming house cats

    Jun 9, 2011 4:00 pm

    A team of University of Illinois researchers, including INHS wildlife veterinary epidemiologist Nohra Mateus-Pinilla and mammalogist Ed Heske, conducted a two-year radio telemetry and activity tracking project on 42 adult cats in Central Illinois to answer that question. They found that pet cats spent only 3 percent of their time engaged in highly active pursuits, such as running or stalking prey while un-owned (feral) cats were highly active 14 percent of the time. Even feral cats stayed near human structures, according to Mateus-Pinilla. The study, "Home range, habitat use, and activity patterns of free-roaming domestic cats" was published in The Journal of Wildlife Management.

  • End-of-June Rainfall Provides Remarkable Transformation

    Jul 6, 2007 7:45 pm

    "The most outstanding feature of June weather was the change from very dry conditions the first 18 days to very wet ones the rest of the month. As a result, crops, lawns, and gardens recovered quickly from abnormally dry conditions that began in May," says State Climatologist Jim Angel of the Illinois State Water Survey (http://www.sws.uiuc.edu), a division of the Illinois Department of Natural Resources. Statewide June precipitation in Illinois was 4.47 inches (0.39 inches above normal), and statewide temperatures were 72.7°F degrees (0.8°F above normal). "That's quite a switch from the first 18 days of June, only 1.03 inches statewide, less than half the 2.42-inch normal for that period. The last 12 days of June had 3.44 inches, about twice the 1.66-inch normal," says Angel.

  • Swarms of mayflies are short-lived

    Jul 6, 2011 4:00 pm

  • Mussel surveys help assess river health

    Aug 26, 2011 8:00 am

    INHS Malacologists Sarah Bales, Josh Sherwood and Amy Stultz were featured in an article in the Rockford Register Star. The team is one of three teams conducting statewide mussel surveys, documenting the location, size, age, sex and species of mussels they find. Mussels are an important part of the ecosystem, filtering pollutants, providing shelter to small organisms, as well as food for larger organisms such as raccoons and muskrats. By understanding the mussel populations in a location, biologists are better able to determine the health of that river.

  • Western corn rootworm developing resistance to rotation

    Sep 4, 2013 8:30 am

    INHS Behavioral Entomologist Joe Spencer is looking at rotation-resistant western corn rootworms, which are causing severe injury to crops. Crops modified to resist infestation by insects and crop rotation are some of the methods to control injurious insects, but some rootworms have developed resistance to these mechanisms. Repeated use of the modified corn year after year has given the rootworms time to adapt. Producers are encouraged to watch their fields for injury. This story was reported in InvestorPlace and the Bulletin.
