  • Arsenic, mercury and selenium in Asian carp not a health concern to most

    A recent study by INHS researchers Jeffrey M. Levengood, David J. Soucek, Gregory G. Sass, Amy Dickinson, and John M. Epifanio showed that overall, concentrations of arsenic, selenium, and mercury in bighead and silver carp from the lower Illinois River do not appear to be a health concern for a majority of human consumers. The full results of the study have been published in the journal Chemosphere.

  • Fig wasps older than known fig trees

    INHS Paleontologist Sam Heads found an ancient fig wasp that pre-dates any known fig trees. According to Heads, “This is a tiny parasitic wasp, it's the smallest fossil wasp found in this particular deposit and it's the oldest representative of its family. More importantly, it’s possible that this wasp was fig-associated, which is interesting because it’s Early Cretaceous, about 115 to 120 million years old. That's a good 65 million years or so prior to the first occurrence of figs in the fossil record.”

  • Freshwater mussel behavior altered by exposure to antidepressants

    INHS Post-doctoral researcher Andrea Fritts is a co-author on a recently published study examining the effects of the antidepressant fluoxetine on the behavior of freshwater mussels, which could impact their survival and role in their ecosystem. The study found that chronic exposure led to "increases in movement, decreased time to movement, and increased likelihood of diurnal movement, and increased rates of lure display in mussels. Changes in mussel movement [in the wild] are likely to increase susceptibility to predation, and may also alter sediment nutrient cycling and oxygenation through changes in bioturbation provided by mussels."

  • Of lice and men (and chimps): Study tracks pace of molecular evolution

  • Lice evolve faster than their primate hosts

    INHS Psocodea expert Kevin Johnson and post doctoral researcher Julie Allen led a recently published study comparing the rate of evolution in primates with that in their louse parasites.

  • Historic numbers of waterfowl in the Illinois River Valley

    INHS researchers at the Forbes Biological Station recorded the historic numbers of waterfowl this year in the Illinois River Valley. At migration’s peak, 329,590 mallards were counted, the highest number since 1999. Northern pintails (141,840), green-winged teal (179,620), gadwall (146,300) and northern shovelers (49,060) were present in the highest numbers since the survey began. Learn more about the waterfowl aerial inventories. Follow the Forbes Biological Station on Facebook.

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

    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.

  • Junior high students add to our knowledge of biodiversity in Illinois

    Junior High students are once again adding to our knowledge of biodiversity in Illinois. Prairie Central Junior High Science teacher Scott Saffer and his seventh grade students conduct herpetological field surveys each year in Livingston County. After catching and identifying reptiles and amphibians, the students have their finds confirmed by INHS Herpetologists Andrew Kuhns and Chris Phillips. This year the students found three more species not previously documented in Livingston County.

  • A new species of Drypetes described

    In a recent paper in Phytokeys, INHS Botanist Dr. Geoffrey Levin described a new species of Drypetes from Costa Rica. This new species of flowering tree produces asymmetrical drupes (fleshy fruits), leading to its name Drypetes asymmetricarpa.

  • Bullfrogs insensitive to road salt

    INHS post doctoral researcher Tanya Hawley Matlaga, INHS Herpetologist Chris Phillips, and INHS Ecotoxicologist David Soucek report that bullfrogs are less sensitive to elevated chloride concentrations than some other amphibian species. The study was designed to mimic the level of salt found in roadside ponds following de-icing events. The study found that bullfrog tadpoles did not experience reduced survival, growth, or ability to evade predation in elevated chloride concentrations, and thus, their populations are not expected to be impacted by road salt. While this is good news for bullfrogs, it's an additional stress for other species inhabiting ponds with these voracious predators.

  • Fungus that causes white nose syndrome is a survivor

    INHS Mycologist Andrew Miller and graduate student Daniel Raudabaugh recently published a paper on the fungus Pseudogymnoascus (Geomyces) destructans, which causes white nose syndrome in bats. In this first, in depth study of the basic biology of the fungus, the researchers found that P. destructans can survive on a wide variety of nutrient sources.

Last year, the trainings focused on forested ecosystems; this year the focus is on Landscape and Nursery pests.

  • Researchers move endangered mussels to save them

  • Western corn rootworm developing resistance to rotation

    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.

  • 1000 more endangered mussels released in Illinois rivers
