    After stocking native fishes in the restored Emiquon wetland just two years ago, the number of birds stopping there has dramatically increased. Dr. Joshua Stafford, Director of Illinois Natural History Survey's Forbes Biological Field Station, gave a report to the 2009 Governor's Conference on the Management of the Illinois River, where he said that the Coot numbers at the wetland went from 30,000 the first year to almost 60,000 the next. More information about the Emiquon wetland restoration can be found in the October 23, 2009 Peoria Journal Star article called "Experiment wildly successful" or the same article can be read at the NewsBank site.

  • Native birds as biological controllers of Emerald Ash Borer Beetles?

    Dec 20, 2013 8:00 am

    INHS Ornithologist Chris Whelan is a co-author on a recent publication reporting that woodpeckers may be helpful in controlling Emerald Ash Borer Beetles. Their study found that bark foraging birds, such as woodpeckers, foraged more heavily on ash trees and preferred ash trees with visible canopy decline over healthy trees. "Predation by bark-foragers significantly reduced tree-level EAB densities by upwards of 85%." The authors conclude that enhancing habitat for woodpeckers and other bark foragers may help control infestations and create more resilient forests.

  • 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.

  • Multi-state team relocates endangered mussels ahead of construction project

    Aug 27, 2012 8:00 am

    Illinois scientists worked with others from the Pennsylvania Fish and Boat Commision, the US Fish and WIldlife Service, and state agencies from Ohio and West Virginia to relocate federally endangered mussels from the Alleghany River in Forest County Pennsylvania. Approximately 3,900 federally endangered riffleshell and clubshell mussels were gathered from the Alleghany River to be relocated to sites in Illinois and Ohio in advance of the removal and reconstruction of the Hunter Station Bridge.  According to INHS malacologist Kevin Cummings, more than 70% of the 300 species of North American mussels are endangered or threatened with the greatest threat being loss of habitat. "Of the 300 species of mussels living in North America, 98 percent of them live in free-flowing rivers. And if you look at a map of large rivers in the United States, there are very few free-flowing rivers left.  [Mussels] are a great indicator species and, when they start to wink out, you know you have an (environmental) issue."

  • Mosquito larvae exposed to stress may be better able to transmit viruses

    Apr 7, 2011 8:00 am

    In a recently published article in Vector Borne and Zoonotic Diseases, INHS Medical Entomologists Ephantus J. Muturi and Barry Alto revealed that exposing mosquito larvae to temperature and insecticide stress may actually increase their ability to transmit viruses. At 30°C but not at 20°C, Ae. aegypti larvae exposed to insecticide were more likely to transmit the virus compared to control treatments. These findings suggest that environmental factors experienced by aquatic stages of mosquitoes contribute to the risk of arbovirus transmission.
