It is challenging to integrate renewable resources into the distribution grid of fossil-fueled power plants when energy is most needed. The results are often intermittent and unpredictable, which makes it difficult to match energy demand with supply.

In three new U.S. Department of Energy (DOE)-funded projects, scientists in the Prairie Research Institute will design systems and explore the feasibility of combining the use of renewable and fossil energy sources to ensure both short and long-term reliability in electric power delivery.

INHS Medical Entomologist Ephantus Muturi was interviewed by the Chicago Tribune about the threat of Zika virus in Illinois. Muturi says that Aedes aegypti, which transmits Zika, has been found in Illinois but does not thrive in our climate. The Asian tiger mosquito, Aedes albopinctus, is found in Illinois, but has not been found to transmit Zika, though more research is needed. 

The average statewide temperature for the three core winter months of December, January, and February was 20.8 degrees. It was 8.2 degrees below average and the fourth coldest December-February period on record, according to Illinois State Climatologist Jim Angel at the Illinois State Water Survey, University of Illinois.

For the fourth time this year, the monthly statewide precipitation has been above average, resulting in the third wettest January-April since 1895, according to State Climatologist Jim Angel of the Illinois State Water Survey (http://www.sws.uiuc.edu), a division of the Illinois Department of Natural Resources.

This spring the Illinois State Archaeological Survey (ISAS) at the University of Illinois Urbana-Champaign will hold its third annual virtual speaker series featuring Native scholars and leaders. The Intersections of Indigenous Knowledge and Archaeology series is intended to center Indigenous voices, increase awareness of the deep Native histories of the Eastern Woodlands, and amplify the experiences and research of Indigenous scholars and leaders. 

Illinois corn growers in the northern and central parts of the state have come to expect some rootworm damage, but University of Illinois entomologists say putting management plans in place now could help growers avoid major losses.

INHS Affiliate and former director of the Illinois River Field Station was featured on CBS Sunday Morning in a story about invasive species. On the Asian Carp, Sass stated "We've seen explosive population growth, a population that has almost doubled every year. We're fairly confident we have the highest wild densities of Asian carp anywhere in the world." David Lodge of Notre Dame says studies estimate that invasive species cost the US Economy on the order of at least $120 billion annually. There are 30 federal agencies involved in the fight against invasive species, with about $1.5 billion spent annually. Education and prevention are key to warding off the invasive species.

Illinois State Climatologist Trent Ford has released the year-end climate analysis for 2024, which was the second warmest year on record in Illinois, with average temperatures between 1 and 6 degrees above normal.

Researchers are using cutting-edge genomic techniques to help the little brown bat, a species at risk due to white-nose syndrome. By analyzing DNA samples from across the bat's historic range, the team aims to uncover genetic insights that could guide conservation strategies. This collaborative effort among scientists and institutions offers new hope for protecting the bat and other vulnerable wildlife. 

As Illinois experiences a third consecutive year of record-breaking rainfall stretching from Chicago to Cairo, researchers at the Illinois State Water Survey (ISWS) have updated the publication that provides Illinois’ standards for expected extreme storms, known as Bulletin 75.

On Sept. 1, 1914, Martha, the last living passenger pigeon, died at the Cincinnati Zoo. This seemingly abundant bird had been decimated by hunting, leaving them vulnerable to other predators. Following the opening of an exhibit at the Harvard Museum of Natural History, INHS Ornithologist Kevin Johnson, who reconstructed the family tree of the passenger pigeon, was interviewed.

Recent research by INHS Ornithologist and Parasitologist Kevin Johnson has found that bird lice have undergone convergent evolution, evolving different body shapes dependent on where they live on the bird. Despite the morphological similarities between lice from the wings of different bird groups, the species are more closely related to other lice species on the same bird group. The same pattern holds true for lice from the head and body. Learn more about Kevin Johnson's research through this video by the U of I News Bureau.

Illinois Natural History Survey scientists studied behaviors of the western corn rootworm to learn why the insect pests have developed a resistance to Bt corn hybrids, once a deterrent that was as effective as soil insecticides but without the human health risks and environmental concerns associated with broad-spectrum insecticides.

To prevent public health crises that result from widespread lead contamination in drinking water, community water supplies are required to closely monitor their drinking water quality. 

Farmers plant or preserve riparian buffers for various reasons, such as improving water quality, controlling erosion, or maintaining hunting habitat. Now, a new study from the University of Illinois Urbana-Champaign underscores the benefits of riparian buffers to terrestrial biodiversity, finding that for every 10% increase in forest cover, an additional species is present.

The statewide average precipitation in Illinois for February was 3.39 inches, 1.46 inches above normal. This ranks as the tenth wettest February since statewide records began in 1895, according to State Climatologist Jim Angel of the Illinois State Water Survey (http://www.isws.illinois.edu).

Major partners include the U.S.  Department of Energy (DOE), U.S. Environmental Protection Agency (EPA), and the state of Illinois.

The Water Survey’s Climate and Atmospheric Science team investigates the potential statewide impacts of climate change, including extreme precipitation changes (flooding, drought), availability of atmospheric resources for green energy generation, changes in the urban heat island, and integration of climate models into systems that take into account human population growth, health, and activities.

Aquifer-based geothermal systems, known as aquifer thermal energy storage, could help ease the environmental stress stemming from artificial intelligence data centers in the United States. Researchers at the Prairie Research Institute at the University of Illinois Urbana-Champaign are proposing a new way to keep those facilities cool by using the naturally stable underground temperatures and groundwater as a giant natural “thermal battery.”

Illinois Sustainable Technology Center scientist Wei Zheng and colleagues are creating a designer carbon-based biochar that captures phosphorus from tile drain runoff water and recycles it in soils to improve crop growth.

Researchers report the first sighting in 30 years of a wild alligator snapping turtle in Illinois. The discovery may be a sign of hope for this state-endangered species, or the animal could be the last of its kind to have survived in Illinois without human intervention, the researchers say.

In a study of crayfish in the Current River in southeastern Missouri, researchers discovered that the virile crayfish, Faxonius virilis, was interbreeding with a native crayfish, potentially altering the native’s genetics, life history and ecology. Reported in the journal Aquatic Invasions, the study highlights the difficulty of detecting some of the consequences of biological invasions, the researchers say.

Tommy McElrath takes readers Behind the Scenes of the INHS insect collection. "Storing your dead tarantulas in a gallon-sized pickle jar is not the best solution to long-term preservation. Especially when those tarantulas are toe-tagged – like corpses in a morgue."

Through a grant from USDA, ISTC and Feeding Illinois partnered with Rendleman Orchards during the 2021 growing season to ensure no fruit went to waste. 

INHS Aquatic Entomologist Ed DeWalt told the Peoria Journal Star that the presence of large numbers of mayflies indicates the water quality is high enough to support this species that spends the majority of its life in water. Mayflies emerge from the water this time of year for to live out their short adult life stage—finding a mate and returning to the water to lay eggs. While some people see them as a nuisance, they don't bite and according to Ed DeWalt, "they will make a mess for a week and then they'll be gone."

INHS Entomologist Chris Dietrich was interviewed about the infestation of mayflies long the Illinois River this week. After spending most of their life in the water, they emerge en masse, overwhelming predators, mate and then die, typically within 24 hours. According to Dietrich, mayflies are an environmental indicator for our rivers, so large numbers of them is a good thing.

The University of Illinois, Feeding Illinois, the Illinois Specialty Growers Association, and the Illinois Farm Bureau are collaborating to collect and collate information on the locations, types, and quantities of “surplus” specialty crops in Illinois, including potential acquisition costs. Through a producer survey, a series of focus groups, and implementation of pilots across the state the team looks to uncover the optimal mix of incentives and program interventions to overcome the current barriers to efficient flows of fresh food produced in Illinois, to Illinois residents, with as little waste as possible.

Illinois Cooperative Agricultural Pest Survey Coordinator Kelly Estes is sampling black walnuts across the state to monitor for the potential of Thousand Canker Disease. If you have black walnut stands on your property or know of stands, ICAPS asks that you submit that information for mapping purposes.

Wading into the springtime muddy marshland, pushing aside a wall of plants taller than her head, ornithologist Anastasia Rahlin looks and listens for signs of black terns and yellow-crowned night herons. She plays a recording, waits 30 seconds, and listens for a return call. The species of birds that she doesn’t find in the marsh are the ones she doesn’t want scientists to forget.

Researchers at the University of Illinois’ Prairie Research Institute are developing new pest degree day tools for the state’s specialty crop growers. A short online survey offers growers the opportunity to contribute their opinions on how this information is delivered.

Natural History Survey scientists, Joshua Stafford, Aaron Yetter, Chris Hine, Randy Smith, and Michelle Horath have been continuing the moist-soil research of Frank Bellrose from the Forbes Biological Station and F. C. Bellrose Waterfowl Research Center in Havana since 2005. In an article featured in the March 2008 issue of Outdoor Illinois, the scientists discuss their research, the work of Frank Bellrose, and management issues for moist-soil habitats.

In the summer’s heat, an Illinois Natural History Survey (INHS) aquatic biology team can be found in shallow rivers or streams under bridges slated for reconstruction, wading in water and sliding their fingers through the rocks and sediment below, searching for the edge of mussel shells. They’ll move the mussels they find out of harm’s way of construction equipment that will soon roll into the area.

As part of an Illinois State Water Survey (ISWS) project to determine the risk of flooding for individual homes and businesses in floodplains, licensed surveyors will visit properties to measure the height of structures from late June to July for two pilot areas in the City of Ottawa and the City of Moline.

Agricultural producers are typically blamed for applying fertilizer that pollutes local waters and carries oxygen-depleting nitrogen and phosphorus to the northern Gulf of Mexico. However, a strong majority of Illinois farmers believe they are doing their part to protect the environment, according to a study from the University of Illinois’ Prairie Research Institute (PRI).

A recent Prairie Research Institute (PRI) study of attitudes about land conservation found that Illinois farmers view themselves as stewards of their land, balancing conservation with earning a profit. Nearly half of farmers surveyed said they would use conservation practices even without financial compensation from federal land conservation programs.
