Good news - the quality of water in the Illinois River has improved in one important aspect. A new study from the University of Illinois reports that nitrate load in the Illinois River from 2010 to 2014 was 10 percent less than the average load in the 1980s and early 1990s.

Reducing the nitrate and phosphorus loads in the Mississippi River by 45 percent is the US EPA’s ultimate recommendation. This will serve to reduce the size of the seasonal hypoxic area, or “dead zone,” created in the Gulf of Mexico when nitrate in tributaries like the Illinois River flows into the Mississippi River and down to the Gulf. Illinois has developed strategies to achieve these reductions described in the Illinois Nutrient Loss Reduction Strategy. Other Midwestern states have developed similar strategies.

Power plants burned coal that released sulfur into the atmosphere, but coal use has declined. In this sample from an Illinois mine, pyrite is visible as gold flecks in the center of the coal. 
 

With the move from burning coal to natural gas and low-sulfur coal and an increase in the use of scrubbers, only about 25 percent as much atmospheric sulfur is available today, compared to 40 years ago. “We don’t think there are actual sulfur deficiencies yet, but clearly more sulfur is coming out of the soil and water than what is going in,” says U of I biogeochemist Mark David.

A new study explores how a young cowbird, left as an egg in the nest of a different species, grows up to know it’s a cowbird and not a warbler, thrush or sparrow.

The study, published in Animal Behavior, reveals that cowbird juveniles leave the host parents at dusk and spend their nights in nearby fields, returning just after daybreak. This behavior likely plays a role in the cowbirds’ ability to avoid imprinting on their host parents.

University of Illinois researcher Cory Suski has already shown that bubbling high concentrations of carbon dioxide (CO₂) into water is a deterrent to invasive Asian carp adults. The gas makes them feel “woozy” and they choose to swim away. His recent research shows that fish the size of an eyelash also experience negative consequences following CO₂ exposure.

“We conducted carbon dioxide challenge experiments on juveniles of four species—largemouth bass, bluegill, silver carp, and bighead carp, and on eight-day-old hatched fry of both carp species,” Suski said. “Results from the study demonstrate that juvenile fishes of all four species actively avoid areas of water with elevated CO₂ once concentrations reached approximately 200 milligrams per liter, which is lower than a can of carbonated soda.”

Thousands of reports are produced every year assessing the effects of different conservation policies and programs, but much of this valuable information is never read. Researchers from the University of Illinois and five other institutions collaborated to highlight the merits of a new technique—creation of evidence maps— to ensure research findings are more visible and accessible. The article appears in Nature.

“Evidence maps are emerging as a powerful new tool to visually distill a huge amount of information on what works and what doesn’t in a particular field,  says Daniel Miller, assistant professor of Natural Resources and Environmental Sciences at U of I.  “We believe the evidence map we’ve created on the effects of nature conservation on human well-being is the first application of this tool to conservation and sustainable development issues.”

Cassandra Wilcoxen, a graduate student working in NRES, studied the effects of conservation practices on local farms to the overall quality of habitat for local wildlife, most notably the mourning cloak butterfly. The results of Cassandra’s study could help address some of the challenges that large-scale farming across the Midwest poses to wildlife. Cassandra herself states, “What I really learned from this summer’s surveys is that the little things farmers—and all of us—do make a huge difference.”

An intricate system of basins, channels, and levees called the Headwaters Diversion protects 1.2 million acres of agricultural lands in southeast Missouri from both overflow from the Mississippi River during flooding events and from Ozark Plateau runoff. More recent extensive rainfall and subsequent flooding prompted University of Illinois researcher Ken Olson to look more closely at where the excess or diverted water goes.

Olson and his colleagues are studying the levees, diversions, and floodways, which for the past 200 years have allowed land conversion from wetlands to agriculture. “It has substantively altered the hydrologic cycle of the region,” he says. “The Little River levee and Little River Drainage District Headwaters Diversion channel built in the 1910s successfully permitted the drainage of the 1.2 million acres Big Swamp in southeast Missouri. However, it also had the unintended consequence of increasing the peak flow of Mississippi River water south of Cape Girardeau through the Thebes gap and south to Helena, Arkansas, a distance of approximately 360 river miles.” Olson says the increase in Mississippi River peak flow placed additional river pressure on levees and led to increased flooding, especially during the floods of 1927, 1937, 2011, and 2015-2016.

Conservation efforts are designed to restrict activities in protected areas, but the restrictions can have unintended consequences. Daniel Miller, a University of Illinois researcher, was intrigued by a conservation intervention that took place from 2001 to 2008 in the W National Park region in Africa. The purpose of the project was to help reverse natural resource degradation and conserve biodiversity so as to benefit local people. Miller conducted interviews from 2010 to 2011 with 300 households in villages adjacent to the W National Park in Benin and Niger. He used the data from the interviews to explain how and why the same conservation project led to different outcomes in the two national political contexts.

The results of the study showed that there were indeed negative consequences for people’s livelihoods, but in Niger the impacts were much greater, particularly for the poorest people and those who saw the most severe reduction in their access to park resources. “Governance matters,” Miller says. “In this case, Benin’s better government and more decentralization led to better social and ecological outcomes. These results highlight the importance of national political context to the outcomes of aid-funded conservation efforts.”

Numerous shorebirds, such as the American golden plover, stopover in East Central Illinois during their spring migration. These birds need time to refuel and recover from their long flights and use wet agricultural fields to find food resources.To help accommodate the birds’ needs, the USDA and the Illinois Department of Natural Resources are offering incentives to landowners willing to delay planting in order to provide valuable habitat to migrating shorebirds and waterfowl.

“Farmers who have a hard-to-farm wet spot on their land may be able to create temporary wet habitat for migrating birds, while receiving compensation for potential reductions in yield,” said Michael Ward, a University of Illinois ornithologist. “We know there are fields that don’t drain very well. If you visit them during migration, you’ll see 5,000 shorebirds there eating at a single time. Farmers have a lot of economic incentive to eliminate water and farm the land as quickly as possible. This program aims to take some of the pressure off of farmers to drain these fields and plant them so quickly by providing an alternative incentive to leave them wet for a while longer,” Ward said.

Upcoming Events
 

On July 7-8, 2016, the College of ACES Alumni Association will host the annual ACES Family Academies, a program offering alumni and their children educational classes to take while enjoying the campus. These classes introduce participants to the variety of subject areas studied in ACES, and provided hands-on experiences with research techniques used by scientists on campus as well as in labs around the world.

NRES will participate by offering a course titled, “Bird’s the Word: Exploring Avian Ecology and Conservation.” Graduate student Janice Kelly and NRES department head Dr. Jeff Brawn will instruct the course and discuss how marking/banding wild birds is an important technique for monitoring avian populations. Participants will be able to see wild birds up close while learning about the ecology and conservation concerns of many familiar birds. The participants will also learn about ongoing research projects conducted by students and faculty in NRES that use mark-recapture data for monitoring purposes.
