Paleomagnetic Determination of the Age of the Serpent Mound Structure

Watts, D. R. ( 2004-09 )

The Serpent Mound structure is a deeply eroded ancient impact in south central Ohio, about 8.0 km across. The age of the structure is poorly constrained by the geology. It post-dates the Lower Mississippian (ca.330 Ma) ...

Janson, Richard W.; Krishna, Lala B.; Steiner, Richard P. ( 2004-09 )

The value added by the work force varies greatly among Ohio’s 88 counties. In the aggregate, the value added equals the gross domestic products (GDP) of the county. With an adjustment for depreciation, the value added by ...
Ultrastructure of the Chorion of Echthistus cognatus (Loew, 1849) (Diptera, Asilidae)

Candan, Selami; Suludere, Zekiye; Kalender, Yusuf; Eryilmaz, Ozlem ( 2004-09 )

The fine structure of the Echthistus cognatus (Loew 1849) chorion was studied using both transmission (TEM) and scanning electron microscopes (SEM). Females were collected in the field and kept under laboratory conditions. ...
Gastropods and Rostroconchs (Mollusca) from the Maxville Limestone (Upper Mississippian) in Ohio

Hoare, Richard D. ( 2004-09 )

The gastropod fauna is abundant and more diverse in the Upper Mississippian Maxville Limestone than previously described. Seventeen species, including 6 reported for the first time, are known and fragments of several others ...
Description of Vegetation of the Oak Openings of Northwestern Ohio at the Time of Euro-American Settlement

Brewer, Lawrence G.; Vankat, John L. ( 2004-09 )

Original land survey notes were used to produce a map of the Oak Openings of northwestern Ohio showing the vegetation at the time of Euro-American settlement (1817-1832). For that period, the area of the Oak Openings was ...
