  2012 Ohio Naturalist's Conference

The 2012 Ohio Naturalists' Conference was held in Columbus on February 11th.  The conference drew about 200 naturalists, botanists, ecologists and zoologists from around the state and even several neighboring states.   It was the 100th anniversary of the sponsoring organization, the Ohio Biological Survey, and the 9 presented papers and over a dozen posters.  Two of the posters were presented by Marietta senior Derek Hennen (above left) - "UV Fluorescing Millipedes from Southeastern Ohio" with Drs. Katy Lustofin (above right) and Dave McShaffrey of the Biology Department, and "A Biological Survey of the Assassin Bugs (Hemiptera: Reduviidae) at the Barbara A. Beiser Field Station" with Dr. McShaffrey.  Both posters represent the first "official" scientific publications based on work done at Marietta College's new field station.  Derek’s assassin bug work is part of his senior capstone project; he reported on 7 species of these predatory insects found at the field station.  The millipede work grew out of discoveries of the millipedes at the field station by Hennen and McShaffrey and subsequent follow-up by Lustofin, who examined previous scholarship on fluorescence in arthropods to put the discovery of the fluorescent millipedes at the field station into context.  McShaffrey also presented a paper on the Ohio Odonata Survey, an effort that several Marietta College students participated in during the 1990’s.  Marietta College was also recognized for its contribution to the Ohio Spider Survey, which is ongoing.
