Species and Population Variability of Osmorhiza Longistylis and Osmorhiza Claytonii
(1980-03) Ostertag, Carol P.; Jensen, Richard J.
Four populations of Osmorhiza, containing either or both 0. longistylis and O. claytonii (Sweet Cicely), were sampled to determine interspecific and intraspecific patterns of morphological variation. Discriminant analysis permitted easy separation of the species when presence or absence of anise scent was used as a criterion variable. The same method permitted separation of 2 populations of 0. longistylis yet did not completely separate 2 populations of 0. claytonii. Significant differences were found for a variety of characters between the 2 populations of 0. claytonii as well as between the 2 0. longistylis populations and between the species. Style length and anise scent were recognized as reliable species indicators whereas pubescence characters were unreliable. Population differences are presumed to be the result of habitat differences, while species differences are apparently genetic.

Improved Culture of Aurelia Aurita Scyphistomae for Bioassay and Research
(1980-03) Groat, Cynthia S.; Thomas, Charles R.; Schurr, Karl
A number of significant pollutants are being found in aquatic environments. Generally, there are no standardized methods or commonly used animal species for bioassay of toxicants. Our study describes a method by which genetically cloned scvphistoma larvae can be grown in chemically defined media and under standardized conditions. We report a 10-step procedure to culture Aurelia aurita scyphistomae successfully on frosted glass microscope slides. Attached scyphozoa larvae are particularly appropriate for both bioassay and physiological research. We reared continuous generations of Aurelia aurita in our laboratory for the past 15 years on a diet consisting of nauplii of Artemia salina. We have found that all available strains of Artemia cysts provide an adequate diet for the Aurelia polyp.
Renal Concentrating Ability and Calcium Load Handling in the Spontaneously Hypertensive Rate
(1980-03) Wright, G. L.; Lowry, L.
The renal response to an oral load of calcium and the renal concentrating ability of spontaneously hypertensive (SH) and normotensive (WKY) rats were examined. The response to calcium loading was similar between SH and WKY animals in terms of urine volume, osmolality and calcium excretion. Compared to WKY controls, the ability of SH rats to concentrate urine during dehydration was decreased. The injection of vasopressin had no effect on the urine output of water-loaded SH rats, although a similar injection returned urine flow to control levels in WKY animals. It is suggested that the decreased ability of the SH rat to limit urine flow was due either to pressor effects of ADH in increasing perfusion pressure or to a decreased responsiveness of the renal tubule to ADH.
Feeding Interrelationships Between the Sand Shiner and the Striped Shiner
(1980-03) Gillen, Alan L.; Hart, Thomas
Feeding habits of Notropis stramineus and N. chrysocephalus were investigated in Buffalo Creek, Washington County, PA during September through December, 1977. As an opportunistic feeder, N. stramineus consumed large quantities of terrestrial (appx. 40%) and aquatic (appx. 50%) insects during September and October, but shifted almost entirely to insects in the benthic environment (appx. 90%), such as mayfly nymphs (Caenis and Stenonema) and stonefly nymphs (Alloperla and Isoperla), in November and December. N. stramineus utilized a wide range of prey with the bulk of its diet in the size class 5-8 mm. N. chrysocephalus consumed larger aquatic prey (9-12 mm) including crayfish (Orconectes), large mayfly nymphs (Stenonema), and damsehiy naiads (Argia) from September through November; however, in December its diet shifted to Cladophora and aquatic Chironomidae larvae. Although diet overlap was nearly complete initially (September and October), it diminished as the season progressed. Food habits were unique to each species late in the year, suggesting that as food resources decline the food habits of these two species appear to diverge, minimizing interspecific competition.
The Aquatic Oligochaeta of the Sandusky River, Ohio
(1980-03) Prater, Bayliss L.; Smith, Kenneth R.; Loden, Michael S.; Jackson, William B.
Aquatic oligochaeta were qualitatively sampled from 10 stations on the Sandusky River between 26 October 1973 and 21 September 1974. Grab water samples were collected and analyzed for 15 parameters at the same stations. Eighteen species were collected with Branchiura sowerbyi, Limnodrilus cervic, L. hojjmeisteri, L. spiralis, L. udekemianus and Tubifex tubifex comprising 97.8% of the total identified fauna. Species composition and seasonal abundance differed in 3 distinct regions of the river, and the most oligochaetes/m2 were collected in July and the least in May. Three sewage treatment plants seemed to have an impact on the number of species and mean number of individuals collected below their outfalls. Species diversity was determined at all stations and was significantly correlated (P<0.5) with 13 of the 15 physico-chemical parameters.

Variation and Predaton of the Pennsylvanian Gastropod Microdoma Conicum Meek and Worthen
(1980-03) Hoare, Richard D.
Our study of a large population of the Pennyslvanian gastropod Microdoma conicum Meek and Worthen, which appears restricted to the Vanport marine unit of the Allegheny Group in Ohio, showed extreme variation in ornamentation of the shell ranging from essentially smooth to coarsely nodose. Smooth and lightly ornamental forms were more common than previously known. Nearly 38% of the population showed indications of external biological activity of one or a combination of 3 types: (1) small hemispherical pits, 0.1-0.2 mm in diameter, which did not penetrate through the shell material and were formed by an unknown passive epifaunal element while the host was alive; (2) borings, 0.2-0.3 mm in diameter, which passed through the shell and possibly were made by another gastropod (3) shell damage along the margin of the aperture at various stages of growth, which may have been caused by one of the associated faunal elements such as echinoids, fish, or nautiloid cephalopods.

Preliminary Archaeological Examination of Ohio's First Blast Furnace: The Eaton (Hopewell)
(1980-03) White, John R.
The Eaton (Hopewell) Furnace located near Struthers, Ohio was built in 1802-1803. The first blast furnace west of the Alleghenies and the first industry of any kind in the Western Reserve, it went out of blast circa 1808 due to a combination of factors and fell into ruin. Historical sources on the Eaton are scarce and informational sources are vague, but archaeological excavations carried out in 1975, 1976, and 1977 have led to some interesting findings concerning early blast furnace operations. Subsequent chemical and metallurgical analyses of furnace artifacts and specimens provided insights into the level of efficiency of the operation and the quality of the raw materials, products, and byproducts. Foremost among these findings is the fact that the Eaton's use of bituminous coal in combination with charcoal was the earliest use substantiated in the New World.
