INHS scientists will be participating in a Bioblitz organized by The Wetlands Initiative (TWI) at Sue and Wes Dixon Waterfowl Refuge at Hennepin and Hopper Lakes in Putnam County on June 13-14. Citizen scientists are invited to help document all of the flora, fauna, and fungi of the area over the course of 24 hours.
White Nose Syndrome, the fungal disease that leads to mortality in bats, has now been confirmed in 11 counties in Illinois. First discovered in New York in 2006, the fungus has spread west, first being detected in Illinois in 2013.
INHS Cave Biologist Steve Taylor told an NPR affiliate that, "between 2013 and 2015, it was like a 95 percent decrease in the number of bats at this site, which in 2013 was in excess of 25,000 bats,"
INHS Entomologist Chris Dietrich was interviewed about the emergence of 13 and 17 year cicadas this spring in southern Illinois. It is uncertain how abundant they will be, as “the cicadas require forest habitats, so they are not found out in open areas or areas that have been paved, or where the trees have been removed, so they’re really going to be restricted to areas where there is natural forest.”
Dietrich advised listening carefully to the chorus, stating, “there are actually four different species – each has a different call."

Richard Weldon Larimore, long-time aquatic biologist of the Illinois Natural History Survey (INHS), died on January 14, 2015 at Urbana, Illinois. He was 91. He is survived by his wife Glenn E. Larimore and three sons Richard L., Kenneth, and Michael Larimore.
Dr. Larimore worked at INHS for more than six decades, beginning in 1946 as a research assistant. He remained associated with this organization until his death. As one of the longest serving staff in the history of INHS, Dr. Larimore has worked with every Chief of INHS except its first, Stephen A. Forbes, who held that position until 1930. David L. Thomas, the seventh INHS Chief, was a former student of Dr. Larimore’s.
A graduate of Rogers High, Rogers, Arkansas, Dr. Larimore completed a BS (Cum Laude) at the University of Arkansas in 1946, an MS at the University of Illinois in 1947, and a Ph.D. at the University of Michigan in 1950.
In addition to his service to the State of Illinois, Dr. Larimore was an Inland Fisheries Expert for the Food and Agricultural Organization of the United Nations. He served in this capacity in Thailand from 1963–1964 and in Indonesia from 1972–1973. Dr. Larimore was a charter member of the North American Benthological Society and a member of a number of other professional organizations including the American Fisheries Society, American Institute of Biological Sciences, Ecological Society of America, and the Illinois Academy of Science.
Dr. Larimore was the epitome of a gentleman and scholar, albeit, a very down-to-earth one. His publication record includes 4 book chapters, 25 technical reports, 29 journal articles as well as a monograph, 2 magazine articles, and contributions to 4 conference proceedings. Perhaps the culmination of his science publishing efforts was INHS Bulletin 35(2) “The Fishes of Champaign County, Illinois: During a Century of Alterations of a Prairie Ecosystem,” which he co-authored with Peter Bayley in 1996. This work is considered the most thorough record of historic data of fishes of any place on earth.
His publication awards include Best Paper Award from the Wildlife Society (1957) and Best Paper Award from the American Fisheries Society (1959). Dr. Larimore was also selected for the Phi Beta Kappa, Omicron Delta Kappa for scholarship and the Phi Sigma National Scholarship Award.
In 2002, he was honored by his family and the University of Illinois with the establishment of the “R. Weldon Larimore/Jordan Creek Endowment Fund” to help perpetuate aquatic research on Jordan Creek, a stream that flows in eastern Illinois and western Indiana, where Dr. Larimore pioneered electro-fishing technology. This fund supports the “R. Weldon Larimore/Jordan Creek Award” granted annually to U of I students or INHS researchers based upon their research proposals.
Dr. Larimore, affectionately known as “Larry by his friends and colleagues, is remembered for his expertise in aquatic science, his institutional memory, and his sense of humor. Both at work and at more informal gatherings, Larry was always a
popular presence. Many of these gatherings occurred at his family’s cabin in the woods overlooking the Salt Fork River near Oakwood, Illinois. Like iron filings to the proverbial magnet, people were drawn to this location, not only by its tranquility and beauty but, by Larry’s personality. Many of us remember him standing around the fire, glass of wine in hand, regaling us with a seemingly inexhaustible trove of anecdotes from his life in science.
With deep sadness but profound fondness, we salute the life of Larry Larimore.

A new species of leafhopper has been named for INHS Entomologist Christopher Dietrich in recognition of his extensive work on the group. The new species, Futasujinus dietrichi, is described in a paper in the October Annals of the Entomological Society of America.

Herbivores (species that eat plants; e.g. caterpillars) consume more non-native (introduced from other places) oak leaf material in areas with diverse native plant communities than in less diverse communities. Why diverse plant communities tend to resist invasion by non-native plants, remains uncertain. Researchers from the Illinois Natural History Survey and the Morton Arboretum have been examining the potential role of herbivores on the invasion of non-native plant species in diverse plant communities.
The researchers examined herbivore damage on leaves of non-native oak trees in arboreta across the United States. They found that non-native oaks in regions with high oak species diversity showed more leaf damage than those in regions with low diversity.
Ian S. Pearse, lead author on the study in the current issue of the Royal Society journal Proceedings of the Royal Society B, says that, “competition for resources has often been thought to limit invasions in diverse plant communities, but herbivory could also limit these invasions.”
While native oaks still suffered more leaf damage than non-native oaks overall, in the absence of native oaks non-native oaks showed even less leaf damage. Pearse conjectures, “Diverse plant communities are more likely to contain herbivores that are able to consume a non-native species, which may help to explain why diverse communities are able to resist invaders while others are easily dominated.”
As the introduction of non-native species increases, protection of intact plant communities and their associated herbivores may become critical to guarding against the non-native species invaders.

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.
