    Ecological Analysis of the Fish Distribution in Green Creek, A Spring-Fed Stream in Northern Ohio
    (1979-03) Swaidner, Jay E.; Berra, Tim M.
    The distribution of fishes in Green Creek, a spring-fed tributary of Sandusky Bay in northern Ohio, was studied from June 1976 through June 1977. A total of 31 species representing 22 genera and 10 families was taken at 8 stations along the length of the creek. Two cold water springs interrupt the longitudinal succession of fishes and cause the stream to be divided into 4 divisions, each with its own ecological characteristics and fauna: I. Upland warm water tributaries with Catostomous commersoni and cyprinids dominant. II. Cold water trout stream produced by stocking Salmo gairdneri near the spring; Coitus bairdi is an abundant native species in this division. III. Marl substrate of low gradient with Catostomous commersoni, cyprinids, darters, and Coitus bairdi. IV. Estuary of Lake Erie with typical lake fishes. The stations with the highest macroinvertebrate biomass also had the highest fish biomass. Various physical and chemical measurements were made, and it was determined that the marl deposits of the springs were not conducive to fish productivity. The distribution of fishes in Green Creek does not follow the classical pattern of longitudinal zonation but is determined by the unusual physical and chemical parameters induced by the springs.

    Effect of Oxygen Desaturation from Carbon Monoxide Inhalation on Erythrocytic 2,3-DPG
    (1979-03) Ramsey, James M.; Korchmaros, Bonnie Z.
    Erythrocytic 2,3-diphosphoglycerate (2,3-DPG), in response to carbon monoxide (CO) hypoxemia, was studied in 12 rabbits exposed to 250 ppm CO for 3 hours. Each animal served as its own control. Individual determinations of carboxyhemoglobin, arterial oxygen content, oxygen saturation, and 2,3-DPG were made before and immediately after exposures to both CO and normal air. After CO inhalation, there was no significant change in 2,3-DPG despite an average reduction of 22% in arterial oxygen saturation. Moreover, there was no significant correlation between individual oxygen desaturations and changes in 2,3-DPG. The data imply that the 2,3-DPG mechanism offers little or no compensation for this form of hypoxia.

    A Method for the Cultivation of Dispersed Epithelial Cells from Mouse Palatal Mucosa
    (1979-03) Piliero, Sam J.; Malek, Khairy W.; Pentel, Leon; Schonfeld, Steven; Grob, Howard
    A cell dispersion method is described for establishing cultures of mouse palatal epithelial cells which are viable in primary cultures and subcultures for extended periods of time. The cells in vitro mainly displayed the normal morphologic characteristics of palatal epithelial cells. As demonstrated by labelling the cells with tritiated thymidine, the monolayers of epithelial cells possess a high rate of DNA synthesis. Karyotypes of the cultured cells show a high percentage of normal displays of chromosomal numbers typical of the mouse strain employed. The number of spontaneous aberrations observed is in agreement with previous investigations using other methods.

    Laboratory Measurements of Elastic Constants of Carbonate Rocks from Southwestern Ohio
    (1979-03) Pearson, Jerome; Richard, Benjamin H.; Simpson, H. Mitchell
    Improved laboratory techniques were developed for the measurement of seismic velocities, elastic constants, and loss factors in rock cores. The method used was the forced and free vibration of cylindrical cores in longitudinal, torsional, and flexural vibration modes. The results from Ohio sedimentary rock cores selected from the Brassficld limestone, the Cedarville dolomite, and the Columbus limestone were compared to limited field measurements using seismic techniques. This comparison demonstrates the advantages of the laboratory techniques, which can be used to study the effects of saturation, compostion, anisotropy, and grain size on elastic constants.

    Long-Term Surface Energy Balance of the Great Miami River Valley
    (1979-03) Clemens, Jerome M.
    Estimates of the monthly average values of the components of the surface energy balance were calculated from climatological data observed at the municipal airport near Dayton, OH, using a method proposed by Sellers (1965). Based on these calculations the Great Miami River valley had an annual total net radiation of 52 kilolangleys. Latent heat flux to the air from the surface is 37 kilolangleys yr~' and a sensible heat flux of 15 kilolangleys yr^1. Heat flux into and out of the soil ranged from about 27 langleys day~x in May and June to — 27 langleys day1 in November and December.

    Rare and Infrequent Plant Species in the Oak Openings of Northwestern Ohio
    (1979-03) Easterly, Nathan William
    Frequency of occurrence changes are cited for 154 rare and infrequent taxa of herbaceous vascular plants listed by Edwin L. Moseley in 1928. Of these taxa, approximately 47% are less frequent now (1978) than 50 years ago. Twentysix percent exhibit the same frequency of occurrence and 27% arc more frequent than they were 50 years ago. Approximately 50% of these rare and infrequent taxa are widespread in distribution, 35% are northern, 7.5% are southern, 6% are western and 3% are originally from the Atlantic Coastal Plain. One hundred thirteen new taxa are cited that were not reported by Moseley 50 years ago.
