  • Digitization Project Finds Anthrax Samples in Collections

    When anthrax became a household name in 2011, even curators of some herbaria were unaware that samples of Bacillus anthracis, the source of anthrax, had been housed in their microfungal collections for more than a hundred years. Recently, a digitization project at the Illinois Natural History Survey unearthed the whereabouts of historical samples, including one at the University of Illinois at Urbana-Champaign.

  • Emiquon producing massive crappie

    INHS Fisheries Technicians Kenny Lookingbill (sunglasses at right) and Collin Hinz (left), reported that recent fish surveys at Emiquon turned up massive crappies, the largest weighing in at 3.4 pounds, 17 inches long. Emiquon is an approximately 3,000 acre restored natural area along the Illinois River and based on these surveys may become the best crappie fishery. INHS Illinois River Biologial Field Station and the INHS Forbes Biological Field Station study the waterfowl and fish populations in that area as a means of evaluating the success of the restoration and management.

    Fire-spawned forest fungi hide out in other organisms, study finds

    When a wildfire obliterates a forest, the first life to rise from the ashes is usually a fungus – one of several species that cannot complete its life cycle in the absence of fire. Scientists have long argued about where and how such pyrophilous (fire-loving) fungi survive, sometimes for decades, between fires. A new study finds that some of these fungi hide out in the tissues of mosses and lichens.

  • Invasive Species Workshop Trains First Detectors in Illinois

    The 2017 Illinois First Detector Workshop on invasive plants, diseases, and insects will be offered at eight Illinois sites beginning in January 2017.

  • Saving our natural heritage, one stopper at a time

    The INHS Insect Collection holds more than 350,000 vials with more than 3 million insect and arthropod specimens inside. About 70 percent of these are in vials with stoppers that are – or could soon be – melting. A National Science Foundation grant supports our efforts to replace these stoppers and protect these specimens.

  • Relationship between conservationists and Papua New Guinea villagers more than just monetary

    INHS Post doctoral researcher Bridget Henning, had a paper published recently looking at market-based conservation in Papua New Guinea. Her research found that although villagers were concerned with the condition of the forest, they placed more emphasis on their relationship with conservationists, expecting conservationists to be present in the village, reciprocate their hospitality, participate in customary ceremonies, and respond to requests for material goods. This research explained that the relationship that maintained the conservation project was not market-based, it was a customary Melanesian exchange relationship that involved material goods, social interactions, and moral obligations.

  • Illinois Natural Areas Inventory discovers new natural areas

    Illinois Natural History Survey scientists have spent the past three years evaluating thousands of sites across Illinois to assess their quality. Biologists have discovered approximately 185 more of these "beautiful little gems," as Randy Nyboer calls them, which were missed during the original inventory in 1978. The Inventory is used by the Nature Preserves Commission to determine protection and management of our remaining natural areas.

  • Asian tiger mosquito

    Asian tiger mosquito gains ground in Illinois

    Researchers report that the Asian tiger mosquito, Aedes albopictus, has become more abundant across Illinois in the past three decades. Its spread is problematic, as the mosquito can transmit diseases–like chikungunya or dengue fever–to humans.

  • Deer ticks more adaptable than previously known

    Deer ticks, the host species for Lyme disease, feed on a variety of animals, with white footed mice (a forest species) as the main reservoir for the disease causing bacteria. INHS Wildlife Epidemiologist Nohra Mateus-Pinilla, graduate student Jennifer Rydzewski and Richard Warner (NRES) found that the highest prevalence of infection at Allerton Park was from the prairie, with prairie voles as the reservoir. "What's exciting about the new findings is that we are dealing with potentially new mechanisms of disease transmission that we just have not explored and perhaps we do not understand," Mateus-Pinilla said. "We need to think outside of what we already know about Lyme disease transmission."

  • assassin bug fossil

    50 million-year-old fossil assassin bug has unusually well-preserved genitalia

    The fossilized insect is tiny and its genital capsule, called a pygophore, is roughly the length of a grain of rice. It is remarkable, scientists say, because the bug’s physical characteristics – from the bold banding pattern on its legs to the internal features of its genitalia – are clearly visible and well-preserved. Recovered from the Green River Formation in present-day Colorado, the fossil represents a new genus and species of predatory insects known as assassin bugs.

  • 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.

  • INHS scientists teach students about conservation

  • Eastern massasauga rattlesnake

    For now, Illinois’ imperiled eastern massasauga rattlesnakes retain their genetic diversity

    Habitat loss, habitat fragmentation and the loss of genetic diversity are the three main factors driving the extinction of many wild species, and the few eastern massasauga rattlesnakes remaining in Illinois have certainly suffered two of the three. A long-term study of these snakes reveals, however, that – despite their alarming decline in numbers – they have retained a surprising amount of genetic diversity.

  • Negative image aside, Asian carp are a boon

    Although there is widespread concern about the spread of Asian Carp, for some people, they represent a new industry and economic boon. Asian Carp harvest has increased thirtyfold in the past ten years. In 2010, a fisheries company in Thomson IL sold 20 million pounds of Asian carp to consumers globally. According to Greg Sass, director of the INHS Illinois River Biological Station, that while Asian Carp represent 80% of fish in parts of the Illinois River, scientific research has not yet established a direct connection between the presence of Asian Carp and the decline of native species.

  • It's mussel time!

  • Cowbirds aren't just deadbeat parents

    A new study from INHS graduate student Matthew Louder, and INHS Ornithologists Wendy Schelsky, Jeff Hoover, and Amber Albores found that female cowbirds monitor nest success of their offspring and will lay their eggs in the most successful host nests. This, combined with previous work by Jeff Hoover and colleagues, shows that female cowbirds aren't just abandoning their eggs in a host nest. Nests that fledged cowbirds were much more likely to be parasitized by cowbirds again than those that failed to fledge cowbirds.

  • Rare salamander sparks excitement in INHS herpetologists

    INHS Herpetologist Chris Phillips was interviewed for a recent installment of Environmental Almanac. Phillips was contacted by a photographer who captured an image of an elusive, fully aquatic amphibian known as a siren, being eaten by a Great Blue Heron in Vermilion County. Sirens are known from southern Illinois but have never been detected by the extensive INHS herpetological surveys of Vermilion County over the past 20 years. Phillips said, "It goes to show you there are still some surprises out there for a herpetologist in the Midwest."

    Warmer springs mean more offspring for prothonotary warblers

    Climate change contributes to gradually warming Aprils in southern Illinois, and at least one migratory bird species, the prothonotary warbler, is taking advantage of the heat. A new study analyzing 20 years of data found that the warblers start their egg-laying in southern Illinois significantly earlier in warmer springs. This increases the chances that the birds can raise two broods of offspring during the nesting season, researchers found.

  • 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.

  • New species of springtail named for resemblance to Lord of the Rings villain

    INHS Entomologist Felipe Soto-Adames and colleagues described a new species of Collembola, Trogolaphysa sauron. It is named for the dorsal pattern's resemblance to the helmet of Sauron, a character in Lord of the Rings, as represented in Peter Jackson's 2001 film. Their paper, released this week by the Journal of Insect Science, revises the taxonomy of the subfamily Paronellinae and describes the new species.
