Mark Wetzel, research scientist and oligochaetologist at the Illinois Natural History Survey (Prairie Research Institute at the University of Illinois at Urbana-Champaign), was awarded the 2014 Distinguished Service Award in May by the Society for Freshwater Science, an international scientific organization with over 1,800 members in over 40 countries that promotes understanding of freshwater ecosystems.
Illinois Natural History Survey herpetologists, led by Michael Dreslik, are involved in a multi-state, multi-agency effort to return the Alligator Snapping Turtles (Macrochelys temminckii) to its native range, which includes southern Illinois. INHS researchers are working with IIllinois DNR, US Fish and Wildlife, Peoria Zoo, and Southern Illinois University. As part of the head-starting portion of the project, students at Pontiac Township High School and Whitney Young High School have helped raise young turtles born at the St. Louis Zoo.
Other partners include the University of Illinois School of Veterinary Medicine, Missouri State University, Tulsa Zoo, Oklahoma Department of Wildlife Conservation, University of Louisiana at Monroe, Louisiana Department of Wildlife and Fisheries, the Missouri Department of Conservation and the Arkansas Game and Fish Commission.
The 97 turtles released this month were equipped with dataloggers and radio transmitters which will allow researchers to track the progress of these turtles in the wild.

INHS Research Affiliate Matt Allender (a professor in the College of Veterinary Medicine) has developed a way to detect the presence of a deadly fungus with less impact on the infected snake.
“We need people to know that they don’t have to anesthetize an animal to collect a biopsy sample or, worse yet, euthanize snakes in order to test for the infection,” said University of Illinois comparative biosciences professor Matthew Allender, an expert in snake fungal disease. “Now we can identify the infections earlier, we can intervene earlier and we can potentially increase our success of treatment or therapy.”
INHS Mycologist Andrew Miller and his graduate student Dan Raudabaugh are working to understand the fungus itself.
This work is being done in conjunction with the long-term INHS research project on the critically endangered Eastern Massasauga Rattlesnake. INHS Herpetologists Chris Phillips and Mike Dreslik have been studying the ecology of the snakes for over 15 years.

Project F-69-R, also known as the “Sport Fish Population and Sport Fishing Metric” project, is developing a Fish Quality Index that will help fisheries biologists evaluate and compare the quality of sport fishing for various species in different water bodies. The collaborative project is headed by INHS Sport Fish Ecologist Jeff Stein. This information can be used to inform anglers of the best places to catch a particular species and to help fisheries biologists manage those species.

INHS Mammalian Ecologist Ed Heske was featured in an article about White Nose Syndrome where he said that the situation "looks kind of pessimistic." Heske is part of a multidisciplinary team led by INHS researchers, that has been surveying Illinois caves for signs of WNS over the past three years. Heske told the Chicago Tribune, "We can only hope that some kind of natural resistance emerges from this, like West Nile that does not have the impact it once had. But bats won't come back like birds because they do not reproduce as fast."

INHS Mycologist Andy Miller was interviewed for an article about hunting mushrooms in Illinois.
"This time of year folks are hunting morels, which seem to grow best if the temperatures are around 75F during the day and 50F at night and there is ample rainfall. Also, these conditions frequently coincide with the flowering of May apples and oak leaves being 1/2 to 3/4" long. We've had anything but steady temperatures this Spring, but with the recent rainfall, if the temperatures would increase slightly, hopefully the morels would start appearing. This season has definitely been delayed by at least a month compared to previous years."

A recent study by INHS Sport Fisheries Ecologist Jeff Stein suggests that anglers involved in catch and release fishing should release male largemouth bass as quickly as possible to return to nest guarding. "One of the main conclusions of the study was that in a lake where there are very few brood predators, when you angle a male away from his nest and then immediately release him, the chance of a negative impact is less, but if the nest is located in a part of a lake where there is a high density of brood predators, once the male is removed, predators get into the nest very quickly," said Stein. "On average, the time it took brood predators to begin eating bass young was less than five minutes in cases where the nest was located near schools of brood predators."

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.
"For the first time, people became aware that you could have this super abundant bird that everyone knew about, and that people could actually cause their extinction," Johnson said. "I guess that raised public awareness that humans can cause the extinction of animals on a scale that hadn't really been done before."
The Migratory Bird Treaty Act of 1918 was established to protect certain migratory birds.

Following the discovery of fossil stick insects by a team of Chinese and French scientists, INHS Paleontologist Sam Heads and Illinois State Entomologist Chris Dietrich were contacted by National Geographic to comment.
Heads told National Geographic that the discovery of fossilized plant mimicking insects, "is yet more tantalizing evidence of early insect-plant coevolution."
Dietrich added that there may be more discoveries to be made in collections of fossil insects waiting to be examined.

INHS Behavioral Entomologist Joseph Spencer and his colleagues in Crop Sciences and Entomology recently released a study in the journal Pesticide Biochemistry and Physiology with findings that there is variation in the effectiveness of RNAi treatments on western corn rootworm (WCR), a major agricultural pest.
Current methods for controlling WCR include crop rotation and genetically modified corn. Research published last year found that some WCR have microbes in their guts allowing them to survive on soybeans long enough to lay their eggs in soil that will be rotated to corn the following year.
While the RNAi treatment tested decreased survival in non-rotation-resistant WCR, the treatment did not decrease the survival of rotation-resistant rootworms. The results suggest that the success of an RNAi treatment may depend on the characteristics of the target population.
