    Barite Concretions from the Cleveland Shale in North-Central Ohio
    (1979-09) Holden, William F.; Carlson, Ernest H.
    Concretions composed predominantly of barite occur in the Cleveland Shale of north-centra] Ohio. They have been traced about 8 km through discontinuous exposures along the Vermilion River in Erie and Lorain Counties. These septarian concretions are flattened in the plane of bedding and average 0 cm in length. The concretions contain a black matrix largely composed of fine crystalline barite, surrounded by a fine-grained pyrite rich shell. Septa composed predominantly of more coarsely crystalline barite are generally restricted to the matrix. Although the source of the barium is unknown, the stratigraphic restriction of the occurrence, the sedimentary character of the barite, and the upper Devonian age of the Cleveland Shale suggest that the occurrence may be related to events that formed important bedded barite deposits of mid-Paleozoic age in Arkansas, Nevada and California.

    Seasonal Distribution of Phytoplankton Biomass in a Nearshore Area of the Central Basin of Lake Erie, 1975-1976
    (1979-09) Reuter, John E.
    Samples for the analysis of seasonal distribution of phytoplankton biomass were collected on 10 occasions between July 1975 and June 1976. Samples were taken from 3 depths in the euphotic zone at 5 nearshore stations in Lake Erie near Ashtabula, Ohio. A bimodal pattern of distribution was observed with fall and spring maxima and the dominance of Bacillariophyceae. Although the maxima were equal in magnitude, the fall peak was longer in duration and was dominated by Stephanodiscus niagarae and Pediastrum simplex. The spring biomass peak was observed on a single collection date and was composed principally of Stephanodiscus niagarae, Skeletonema subsalsum, Melosira italica and Cyclotella sp. The Cryptophyta were common throughout the study while representatives of the Cyanophyta and Pyrrhophyta were only abundant in a single collection. The occurrence and distribution of Skeletonema subsalsum (Bacillariophyceae) are discussed.

    Responses of White-Footed Mice and Meadow Voles to Flyovers of an Aerial Predator Silhouette
    (1979-09) Bildstein, Keith L.; Althoff, Donald P.
    The response of white-footed mice and meadow voles to a stylized hawk model pulled overhead was studied. Behavior such as looking up and following the path of the model, immobility, and/or entering a nest can was observed and statistically analyzed. Overall responsiveness peaked as the model passed directly overhead. Stationary models elicited fewer instances of immobility than moving models while significantly increasing the number of white-footed mice that entered nest cans. Meadow voles were more likely to move about the 36 x 20 x 15 cm cage, but not into nest cans, during stop-go flyovers than during non-stop flyovers.

    Terrestrial Bryophytes as Indicators of Air Quality in Southeastern Ohio and Adjacent West Virginia
    (1979-09) Stefan, Michael B.; Rudolph, Emanuel D.
    Bryophyte community as well as individual moss species characteristics on soil were examined to determine relationships with proximity to three coal-fired power plants emitting SO2 and a ferroalloy plant emitting chromium among their emission products. Woody vascular plant communities were relatively uniform, whereas bryophyte coverage was halved (from 3.36% to 1.47%) when comparing locations relatively distant from the plants with those closer. Other common community indices varied little with locality. Three moss species which showed the most consistent relationship to distance from the power plants, Dicranum scoparium, Leucobryum albidum, and Polytrichum ohioense, were mapped for presence or absence on 68 similar hillside habitats. D. scoparium and L. albidum consistently were absent in the area most influenced by the emission sources, while P. ohioense was less consistent in its absence. Presence or absence of indicator moss species proved more useful than community characteristics for indicating relative air quality.

    Soil Types and Arborescent Species of a Specific Woodlot in Ottawa County, Ohio
    (1979-09) Hamilton, Ernest S.; Limbird, Arthur
    A woodlot in close proximity to the Davis-Bcssc Cooling Tower is described, in terms of arborescent species composition and distribution in relation to two soil types. Fulton silt loam and Toledo silty clay loam play a role in species distribution as do moisture and nutrient availability. The Toledo soil has more available calcium and magnesium and higher organic matter, clay content and cation exchange capacity. Higher soil moisture levels have a major effect on soil aeration that results in reduced nutrient uptake. Consequently, high arborescent seedling mortality and selectivity is characteristic of the Toledo soil, and many species with rather restricted soil-moisture and soil-aeration tolerances are eliminated. Celtis occidentalis appears to be the indicator species of the somewhat better drainage conditions of the Fulton soil. This species seems to avoid the more water saturated conditions characteristic of Toledo soils.
