  • Illinois Birds: A Century of Change receives more attention

    Co-author Mike Ward was interviewed by the Chicago Tribune about the recently published "Illinois Birds: A Century of Change." Mike Ward said that the results of the most recent studies were somewhat encouraging. "There's definitely reason to be concerned for certain species of birds, but I don't think we're at the worst point in the last 100 years. I think the worst point was definitely somewhere between the 1950s and now, when our waters were really contaminated and there was a wider use of nasty pesticides. There's reason for concern today, but on the flip side there are definitely triumphs."

    A recent article in Biology Letters, authored by INHS Ornithologist Kevin Johnson and his colleagues Vincent Smith, Tom Ford, Paul Johnson, Kazunori Yoshizawa, and Jessica Light, reveals that the ancestors of the lice found on modern day birds and mammals began to diversify prior to the mass extinction of the dinosaurs at the Cretaceous–Palaeogene boundary, 65 million years ago.

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

    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.
