    Effectiveness of Antimycin A, Oligomycin, and Sodium Cyanide as Inhibitors of Rat Bone Marrow Oxygen Utilization
    (1976-05) Gesinski, Raymond M.
    The inhibition of oxygen consumption was studied in vitro using the metabolic inhibitors antimycin A, oligomycin, and sodium cyanide. Primary concern was to determine the rate and extent of oxidative inhibition upon intact rat bone marrow cells. At concentrations of 5 x 1()~2 sodium cyanide, or higher, inhibition was total and immediate. At a concentration of 5 x 10~3 it was found that sodium cyanide was not significantly inhibitory during the first ten minutes of incubation. Antimycin A and oligomycin were found to be significantly inhibitory for oxygen consumption within two minutes at the 5 x 1()~2 and 5 x 1()~3 concentrations. At concentrations higher than 5 x 10^2 antimycin A and oligomycin were equally effective inhibitors of oxygen consumption. Use of lower concentrations of the two antibiotics showed that oligomycin was slightly more inhibitory to bone marrow oxygen consumption than antimicycin A.

    Food of the Yellow Perch, Perca Flavescens, Following a Decline of the Burrowing Mayfly, Hexagenia Limbata
    (1976-05) Clady, Michael; Hutchinson, Brendan
    Changes in consumption of benthic invertebrates by yellow perch, Perca flavescens, in Oneida Lake during 1958-1973 were similar to changes in the bottom fauna of the lake from 1956 to 1974. The burrowing mayfly, Hexagenia limbata, which declined to extinction following severe oxygen depletions, was replaced in the diet by chironomids and amphipods and, to a lesser extent, by isopods and trichopterans. A slight decline in the growth rate of older perch occurred in recent years, which may be related to the disappearance of the mayfly. No obvious change in abundance of perch was evident.

    Petrified Pennsylvanian Age Plants of Eastern Ohio
    (1976-05) Rothwell, Gar W.
    The recent (1975) discovery of coal-ball petrifactions in the Duquesne and Ames coals of the Conemaugh Group provides an opportunity to make detailed studies of abundant and well preserved Pennsylvanian age fossil plants. Material from these beds was collected at a single location west of Steubenville, Ohio. Remains assignable to all the major groups of coal swamp plants were present, with the psaroniaceous tree ferns and medullosan seed ferns most abundantly represented. To date, 50 distinct taxa of plant remains have been discovered.

    Misfit Streams and the Possible Glacial Origin of Their Valleys
    (1976-05) Richard, Benjamin H.; Paillet, Frederick L.
    A study of misfit streams and meandering depressions developed in ground moraine deposits near Dayton, Ohio has indicated that streams are re-establishing old stream courses, which persist as buried channels previously carved into bedrock. The erosion of deep meandering channels in bedrock appears consistent with melt-water streams let down through glacial ice. Such channels would subsequently be filled with porous stream deposits in post-glacial times, allowing for rapid groundwater flow and enhanced solutioning of predominantly carbonate stream gravels. Once the depressions were lowered below the water table through groundwater solution, misfit channels were established by normal stream erosion. The detailed study of one misfit stream located near Byron, Ohio has indicated the presence of a buried bedrock channel 90 feet deep with a bedrock surface gradient of 400 feet per mile.

    Evaluation of Infrared-Sensitive Film for Determination of Spectral Quality within a Forest Canopy
    (1976-05) Floyd, Bradley W.; Noble, Reginald D.
    Kodak Ektachrome Infrared film was evaluated in terms of its potential use for qualitative spectral information on solar radiation within plant canopies. It was found that an exposure rating of 125 (ASA) provides properly exposed images using through-the-lens metering, with infrared images of forest species in shaded areas appearing deep red (as these species reflect strongly in the infrared), while images of sunfleck illuminated species appear yellow because they reflect in the green spectral region. Infrared color film serves as an inexpensive means of supplementing spectroradiomctric analysis of light within canopy systems, and provides semi-qualitative information about the source of radiation of a particular wave-length. The major limitation observed was the film's tendency to form numerous colors which, in effect, masked the primary colors.

    Lobarochiton, New Generic Designation for Gryphochiton? Anomalus (Rowley) (Polyplacophora)
    (1976-05) Hoare, Richard D.
    A new generic designation Lobarochiton is proposed for the Lower Mississippian taxon originally described by Rowley (1908) from the Louisiana Limestone of Missouri as Platyceras (?) anomalum. Williams (1943) recognized the polyplacophoran affinities and questionably assigned the taxon to the genus Gryphochiton Gray. Subsequent study of the holotype, a tail valve, has shown the presence of primitive insertion plates and differences in valve shape and outline which distinguish it from other known genera of polyplacophorans. Lobarochiton is assigned to the Family Lepidopleuridae Pilsbry, 1892.

    A New Genus and Species of the Gastropod Family Struthiolariidae, Antarctodarwinella Ellioti, from Seymour Island, Antarctica
    (1976-05) Zinsmeister, William J.
    A distinctive species of struthiolariid previously referred to as Slruthiolarella by Wilckens (1.911) is assigned to the new genus Antarctodarwinella. Anlarctodarwinella is proposed for medium sized, semi-globular, heavily calluscd Antarctic struthiolariid gastropods with a moderately elevated conical spire consisting of 4 to 5 whorls. This genus is represented by the species Antarctodarwinella ellioti n. sp. and A. nordenskjoldi (Wilckens). Although the genus has not been recognized outside Anttarctica, it is very abundant throughout the lower 620 feet of the Seymour Island Series exposed, on the northern third of Seymour Island.

    Effects of Illumination and Temperature on Metabolic Patterns of the C-Incorporation by the Moss, Dicranum Scoparium
    (1976-05) Wu, Pei-Hsing Lin
    The moss, Dicranum scoparium, conditioned and maintained at temperatures ranging from 0° to 10°C, was subjected to acetate-2-14C incubation at 5° and 22°C in the presence or absence of added illumination. Patterns of 14C-incorporation into various non-protein fractions (including lipid-fatty acids) respired CO2, and alcoholic solubles were examined. The 14C-labeled metabolic products in amino acid-, organic acid-, and sugar-pools were separated and identified with column and thinlayer chromatographic techniques. Radioactivity increased in the sugar-pool under illumination regardless of incubation temperatures. The radioactivity in glucose remained unchanged regardless of illumination, but the formation of sucrose appeared to be light regulated. The combined regime of added illumination and raised temperature brought about an increase in activity for organic acid and a decrease in amino acid-pools although a sharp rise of 14C-glutamine was occurring in the latter pool. High light gave rise to more 14C-amino acids than those with a low light, regardless of incubation temperatures. Total level of activity in lipid-fatty acid pool remained unchanged during changes of illumination and incubation temperature, while its components, Lx and L2, fluctuated.

    Asplenium X Clermontae Sim from Clifton Gorge, Greene County, Ohio - A Second North American Record
    (1976-05) Wagner, W. H., Jr.; Wagner, Florence S.
    The Ohio Asplenium X clermontae, like the earlier collections from Vermont, seems to differ slightly from the european examples of the same hybrid combination in the structure of the basal pinnae. We examined the mciotic chromosomes in spore mother cells taken from the greenhouse-grown plants. The parents at this locality arc both tetraploids, each with n = 72, 2» = 144. We can conclude we have at least an approximate estimate of pairing behavior in the hybrid.
