Wave Activity in Lake Erie Near Ashtabula, Ohio
(1982-12) Danek, L. J.; Alther, George R.
A study of the hydraulic regime of Lake Erie near Ashtabula, Ohio, was conducted from June 1975 to September 1976. The objective of the study was to determine the deposition and fate of dredged material disposed in Lake Erie. One of the aspects of this study involved the observation of wave activity in this area, to determine the general wave climate and the potential for wave energy to resuspend and transport sediments.
Selective Ocurrence of Arborescent Species on Soils in a Drainage Toposequence, Ottawa County, Ohio
(1982-12) Hamilton, Ernest S.; Limbird, Arthur
The arborescent species composition of a woodlot on the southern shore of Western Lake Erie is described using the analysis of data collected from a series of quadrats located throughout the woodlot. The range of tolerance to edaphic moisture conditions for selected species, in particular Fraxinuspennsylvanka, and Fraxinus pennsylvanka var. subintegerrima, indicates a range of habitat conditions under which individual species are competitively successful. Two soils, a somewhat poorly drained Nappanee silt loam and a very poorly drained Toledo silty clay vary in several of the chemical properties analyzed as well as in moisture status and thus influence soil moisture availability, aeration, and nutrient availability. These soils seem to play a key role in maintaining 2 distinct arborescent community types within this woodlot.
Feldspar-Provenance Dates in a Stratigraphic Section of Till in Gahanna, Ohio
(1982-12) Taylor, Karen S.; Faure, Gunter
The internal layering and provenance of feldspar in 3 tills and in one outwash deposit at Gahanna, Ohio, were studied by determining pebble lithologies and Rb-Sr dates of feldspar. Variations in lithology of pebbles and in the Rb-Sr ratios of feldspar in the 125—250 micrometer fractions reveal discontinuities which divide the upper 2 tills into 2 subunits each. Each of the lower subunits appears to be more homogeneous than the upper ones based on comparisons of standard deviations. This suggests the lower subunits may be basal or lodgement till and the upper subunits may be ablation till. Feldspar-provenance dates in till of the mid western United States are expressions of the proportion of mixing of feldspar grains originating from the Superior (2.7 b. y.) and Grenville (1.07 b. y.) structural provinces of the Canadian Precambrian Shield. The Rb-Sr dates of feldspar in the layers of till and outwash of the Gahanna section are so variable that average dates cannot be used to distinguish among them. The lack of systematic stratigraphic variation of provenance dates indicates the feldspars are heterogeneous mixtures of the two Precambrian components. Approximately 90% of the dates have values between 1.0 and 1.5 b.y., which demonstrates the dominance of feldspar derived from the Grenville Province. Four samples whose dates are less than 1.0 b. y. contain younger feldspar presumably derived from sandstone of late Paleozoic age.
Smallmouth Bass Nesting Behavior and Nest Site Selection in a Small Ohio Stream
(1982-12) Winemiller, Kirk O.; Taylor, Douglas H.
Individual smallmouth bass, Mkropterus dolomieui, were observed in a 500-m stretch of Indian Creek, Ohio, during May and June of 1980 and 1981. Nineteen nests were found in 1980; 8 of which received eggs. Spawned nests were more often guarded by larger males than unspawned nests and were located at sites which were protected from increases in water current velocity during moderate flood stages. Unspawned nests were abandoned within 2 days of the peak spawning activity at Indian Creek, and prior to damage by moderate flooding on 11 and 12 May. Extensive flooding on 17, 18 and 19 May terminated smallmouth bass nesting behavior and appeared to destroy all nests under study in 1980.
The Effect of Somatotropin and Hypergravity on Weight Bearing Epiphyses of Cockerels
(1982-12) Negulesco, John A.; Delphia, John M.; Cisneros, A.; Lang, E.
Somatotropin (STH) administered to earth gravity birds (1 g) stimulated the mean growth in height of the articular cartilage layer of the distal tibial epiphyses (DTE) and of the resting and proliferating layers of the proximal epiphyses of os tarsometatarsus (PE-TMT). However, it inhibited growth in height of the calcified cartilage zone of both epiphyses. Hypergravity control animals (2 g) showed a decreased growth in mean height of proliferating, maturing and calcified cartilage zones of the DTE as well as in the resting and calcified cartilage of the PE-TMT. Hypergravity (2 g) plus STH decreased mean height of articular cartilage zones of the DTE while increasing this parameter within the PE-TMT. The growth in height of maturing cartilage layer of the DTE and of the calcified cartilage zone of the PE-TMT was significantly decreased by administration of the hormone under hypergravity conditions.
Survey of the Vegetation and Flora of a Wetland in Kiser Lake State Park, Champaign County, Ohio
(1982-12) Neff, Karen L.; Vankat, John L.
We classified plant communities by criteria of physiognomy, environment, and flora. Use of Mueller-Dombois and Ellenberg's classification scheme for the world's vegetation provided 6 vegetation categories. The results of a Bray-Curtis ordination were consistent with our field observation of a correlation between these vegetation categories and a soil moisture gradient. The results of a cluster analysis were consistent with 5 of the vegetation categories, but the sixth should be subdivided according to variations in floristic composition. Our proposed classification has 8 plant communities: an alluvial forest dominated by Acer negundo and Parthenocissus quinquefolia, a reed swamp dominated by Eupatorium perfoliatum and Typha latifolia, a deciduous thicket dominated by Crataegus punctata, a second deciduous thicket dominated by Cornus obliqua and Aster pilosus, and a third deciduous thicket dominated by Rosa palustris and R. setigera, a perennial forb community dominated by Clematis virginiana and Verbesina alternifolia, a tall-sedge swamp dominated by Carex stricta and Eupatorium maculatum, and a herbaceous floating meadow dominated by Typha latifolia and Eupatorium perfoliatum. We list 183 species (of 61 families) and state the communities in which each is common.
Abundances of Micrometazoans in Three Sandy Beaches in the Island Area of Western Lake Erie
(1982-12) Evans, Wayne A.
During August 1978 the interstitial micrometazoa of 3 beaches on Kelley's, Pelee and South Bass Islands in the western basin of Lake Erie were sampled. Representatives of the following taxa were found: Acarina, Cladocera, Copepoda, Ostracoda, Gastrotricha, Oligochaeta, Rotifera, Tardigrada and Turbellaria. The South Bass Island beach had the greatest mean density of micrometazoans (46.5/cm3), followed by the Pelee Island (14.2/cm3) and Kelley's Island (5.2/cm3) beaches. The South Bass community was numerically dominated by turbellarians, the Pelee community by rotifers and the Kelley's community by rotifers and gastrotrichs. The mean density of total fauna decreased with depth in the sand (70% in the top 1 cm) except at subsites in the wave-influenced zone at the water's edge where 60% of the fauna were found in the 2—3 cm depth fraction. The densities of most taxa were significantly affected by an interaction between position on the beach and depth in the sand. Densities of the 4 most abundant rotifer genera (Trichocerca, Lecane, Wierzjskiella and Cepbalodella) varied among beaches and as a function of position and depth. The gastrotrich genera Chaetonotus, Icbthydium and Lepidodermella exhibited strong differences in their distributional patterns, with only one genus abundant at any beach, position or depth. The tardigrades Hypsibius augusti and Hypsibius saltursus were found in low densities (combined mean of 0.5/cm3) below the waterline only on Pelee Island.
Crayfish and Bivalve Distribution in a Valley in Southwestern Ohio
(1982-12) St. John, F. Lee
The crayfish and bivalve fauna of 2 stream systems in an ancient valley in southwestern Ohio were examined. The distribution of the various species was mapped and the topography and environmental conditions of each collecting site were noted. The greatest diversity of species was usually found at the edge of the valley, while environmentally stressed sites harbored neither decapods nor bivalves. One species of crayfish, Orconectes sloanii, was found in the northwestern drainage system of the valley, but not in the southeastern drainage system, even though the 2 stream systems were once connected.
Responses of Captive Meadow Voles to Flyovers of a Northern Harrier and an American Kestrel
(1982-12) Bildstein, Keith L.; Beal, Kathleen G.
Meadow voles responded to harrier and kestrel flyovers by looking-up and tracking the flight path of the bird, by entering into behavioral freezes, or by running into their nest cans. Voles responded more frequently when they could see, as well as hear, the bird overhead. When they could see the bird overhead, voles responded more frequently to the harrier than to the kestrel. Shifts in the flight pattern of the harrier did not significantly influence vole responses. Responses of voles to aerial predators may be linked to vole selection of areas with heavy protective cover.
Population Ecology of Common Gallinules in Southwestern Lake Erie Marshes
(1982-12) Brackney, Alan; Bookhout, Theodore A.
Population size, distribution, reproduction, and habitat selection of common gallinules (Gallinula chloropus) were studied in 1977-78 in the southwestern Lake Erie marshes in Ohio. Gallinules were censused by playing a tape-recorded call and counting the number of individuals responding within a 40-m radius. Eight to 30 of these 0.5-ha circular plots were placed randomly in each of 16 marsh habitats. The frequency of nonresponse was estimated from the responses of pairs with known locations, and estimates were corrected for nonresponse. Nest-density estimates from strip-transects were not different (P > 0.05) from pair-density estimates based on calling males. Pair-density estimates ranged from 0.2 to 4.6 pairs per ha. The population for 1978 was estimated to be 1,197 ± 149 pairs in 5,188 ha of wetland. Clutch size averaged 8.04 ± 0.56 eggs for 55 clutches, and 77% of 61 nests hatched at least 1 egg. Twenty-eight brood counts averaged 3.6 ± 0.6 fledged young. Gallinule densities were highest on semipermanently flooded wetlands with narrow-leaved, persistent emergent vegetation, an abundance of submergent aquatic plants, and a 1:1 ratio of cover to open water.
Hatching and Naupliar Development in Cyclops Vernalis (Crustacea: Copepoda) in Relation to Available Dissolved Oxygen
(1982-12) Helm, James G.; Hubschman, Jerry H.
The eggs of Cyclops vernalis were gassed with varying quantities of oxygen and nitrogen, then allowed to hatch and the larvae to develop. A critical threshold of available dissolved oxygen was observed at 1.34 mg O2/l; below this level, hatching dropped to 15%. At 0.38 mg/l hatching did not occur. A similar threshold of survivorship (23%) was observed at 1.34 mg O2/l. Below this level, no organisms reached the first copepodid stage. Survival above 70% required 2.67 mg O2/l dissolved oxygen. Most naupliar mortality occurred at the initiation of ecdysis reflecting the stress imposed by oxygen crisis. A detailed description of the gassing procedure and apparatus is provided.
