Mussel survival rate after relocation is high, according to new research from the University of Illinois’ Prairie Research Institute (PRI).

  • Cornboy vs. the Billion-Dollar Bug

    There is, despite the name, nothing urban about Piper City, Ill. It is a farm town with a skyline of grain elevators, a tidy grid of pitch-roofed houses and, a few blocks beyond, endless fields: corn, soybean, corn, soybean, corn, corn, corn, perfectly level, perfectly square, no trees, no cows, no hedgerows, no bare land. In late August of 2013, a man named Joseph Spencer followed a corn-flanked county road northwest from Piper City until his GPS advised him to leave the road altogether and turn onto a gravel track. Spencer, an entomologist who studies farm insects, was looking for a farmer named Scott Wyllie.

  • 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).

  • Tick-infested songbirds help spread Lyme disease

  • INHS team discovers new invasive clam species

    They found it in the Illinois River near the city of Marseilles, Illinois, about 80 miles west of Lake Michigan—a strange entry point for an invasive Asian clam. The scientists who found it have no idea how it got there. But the discovery—along with genetic tests that confirm its uniqueness—means that a new species or “form” of invasive clam has made its official debut in North America. This is only the latest invasive aquatic species to settle in North America, said Illinois Natural History Survey aquatic ecologist Jeremy Tiemann, who discovered the new clam with INHS mussel field biologist Sarah Douglass in late 2015.
