Japanese students get science lesson at UIS
This week, their studies would show them why it may not be a good idea to swallow the water should they fall out of the boat.
The students and two teachers from Ashikaga Boys High School in Ashikaga, Japan, are at UIS for a Science Academy Program funded by the Japanese government. During the weeklong trip, which began Thursday, the students are learning sampling techniques, fundamental water analysis and basic molecular biology and how it relates to conservation.
Ashikaga has been Springfield’s sister city since 1990, and UIS is hosting a group of science students from the same 600-student high school for the third year.

Susan Koch: University experience reaches to Emiquon
"Some of the most important opportunities that make up an exceptional university experience occur well beyond the classroom and the campus. For many students who attend the Springfield campus of the University of Illinois, some of the best of those opportunities happen about an hour northwest of Springfield near Havana—at Emiquon.
In 2007, The Nature Conservancy and the U.S. Fish & Wildlife Service identified this 7,000-acre stretch of land along the western bank of the Illinois River to transform it from farmland back to its natural state—a river floodplain. The intent was to re-establish the ecological diversity that had once sustained generations of plant and animal life. This remarkably successful project represents one of the first and largest river reclamation efforts anywhere in the world.
Recognizing that the reclamation would be a unique opportunity, University of Illinois Springfield biology professor Dr. Michael Lemke, whose research focuses on freshwater ecosystems, proposed that UIS partner with the Nature Conservancy to establish a field station at Emiquon to study and document this immense experiment. Today, Lemke serves as director of the field station, and thanks to his leadership and the involvement of many other UIS faculty, staff and supporters, the UIS Therkildsen Field Station has become a thriving, year-round, interdisciplinary teaching and research facility that has hosted hundreds of scientists, teachers, students and interested visitors."

First Nature Trek to feature wild turkeys
Wild turkeys are the topic for the first Nature Trek, a collaborative project between Dickson Mounds State Museum and the University of Illinois at Springfield's Therkildsen Field Station at Emiquon. As the museum's assistant curator for anthropology, Harn is the inaugural speaker in a series which will take place on the third Thursday of the month, spring through summer. It's a challenging choice, given wily wild turkey history.
"They're the most elusive gamebird - the most elusive game - in America," Harn says.
Apparently, that didn't help them much with our pioneer ancestors. Once-abundant turkeys disappeared from Illinois by 1910, thanks to a combination of overhunting and cleared forest lands. But in 1959, the birds were re-introduced to the Shawnee Forest in southern Illinois, unexpectedly thriving in the mix of cropland and wooded areas which remains. There are an estimated 135,000 wild turkeys in the state now.

UIS grad student offers hope for rare fish
Nathan Grider, a graduate student in biology, has been studying the alligator gar, a fish that has inhabited waterways in North America for 3.5 million years.
Distant cousins of the alligator gar are known from fossil records at least 118 million years old.
Despite the gar’s staying power, its numbers are falling, Grider said.
“In the last century, they have been showing signs they are declining,” Grider said. “They’ve been around this long, and we’d hate to lose them now.”
For his study, Grider introduced 100 alligator gar into The Nature Conservancy’s Merwin Preserve at Spunky Bottoms in September 2011. Merwin Preserve is a restored backwater wetland in Brown County.
Grider's research was featured by the State Journal-Register on December 24, 2012.

Illinois River wetlands project earns international recognition
The Emiquon Complex in Fulton and Mason counties and the Dixon Waterfowl Refuge at Hennepin-Hopper Lakes in Putnam County were designated “Wetlands of International Importance” by the Ramsar Convention.
Ramsar is an intergovernmental treaty established in 1971. Member countries commit to conservation and “wise use” of wetlands and their resources. Wetlands have to meet a set of criteria to qualify. Only 34 sites in the United States have received the designation.
Michael Lemke, director of the University of Illinois at Springfield Therkildsen Field Station at Emiquon, said he hopes the recognition prompts more students to take advantage of the site that is just over an hour’s drive from Springfield.
“As we know, (the Emiquon story) is a story of human history, anthropology, economics and the list goes on and on,” he said. “I think UIS students should jump on it with both feet."
The Ramsar designation was featured in a August 9, 2012, article in the State Journal-Register.

Emiquon honored for rescuing endangered species, plants
The Emiquon Compex and Dixon Refuge both were designated Wetlands of International Importance by the federal government earlier this year in accordance with the Ramsar Convention on Wetlands, an international treaty signed by 162 nations committed to the protection of wetlands. Only 34 sites in the United States have received such designation.
Doug Blodgett, director of river conservation at The Nature Conservancy spoke about the many partners who have made Emiquon possible.
Blodgett said he was delighted that the University of Illinois Springfield’s Therkildsen Field Station had been built in 2008, and those present were welcome to tour the field station. He pointed out Danny Rosenkranz, a graduate student at UIS, worked on the Ransar application in cooperation with Mike Lemke, director of the field station. Rosenkranz contacted numerous people and dealt with many documents.
Rosenkranz said in a brief interview that he worked closely with Dr. Lemke. Asked about stories of seeds lying dormant for around 80 years springing to life after the Thompson and Flag lakes were restored, Rosenkranz said there were some examples of that with tubers. He said he did not know the species, but they came back after the area was reflooded.
"It's just the beginning stage. Who knows how things will change? It's just amazing," he said.
The Ramsar designation was featured in a August 9, 2012, article in the Canton Daily Ledger.

Science meeting tracks Emiquon progress
Doyn Kellerhals, a graduate student at the University of Illinois at Springfield, presented her research on the bacteria that decompose leaves of silver maple trees. Bacteria are very difficult to tell apart until they are examined at a DNA level.
She is learning that bacterial communities change as leaves break down. And different bacteria are at work in different habitats.
Kellerhals reminded the audience that the small things really do matter.
“I really like talking about the fish and the ducks, but this is where it all starts.”
Kellerhals was featured in a March 5, 2010, article in the State Journal-Register.
