Helminth Parasites of the Brown-Headed Cowbird, Molothrus Ater Ater, from Ohio
(1973-11) Cooper, C. Lawrence; Troutman, E. Louise; Crites, John L.
A total of 166 Brown-headed Cowbirds was examined for the occurrence of helminth parasites. Of these, 116 were collected on the campus of The Ohio State University, Franklin County, Ohio, from January 1964 through February 1965. The remainder of the birds were collected on South Bass Island, Ottawa County, Ohio, from July 1969 through July 1970. Twenty species of helminth parasites are recorded from these birds. Sixteen of these helminth species are new host records: the trematodes Conspicuum icteridorum, Lutztrema sp., Prosthogonimus macrorchis, Tanaisia zarudnyi, and Zonorchis alveyi; the cestode Orthoskrjabinia rostellata; the nematodes Capillaria caudinflata, C. ovopunctatum, C. tridens, Chandlerella quiscali, Diplotriaena bargusinica, Microtetrameres sp., Splendidofilaria algonquinensis, Syngamus trachea, and Tetrameres americana; and the acanthocephalan Plagiorhynchus formosus.
Changes in Biomass of Six Dominant Plant Species During Oldfield Succession in Southeastern Indiana
(1973-11) Root, Robert A.; Wilson, Roger E.
A study of the secondary succession in abandoned corn fields based on biomass of six selected common plant species was made in an area of alluvial soils in southeastern Indiana. It was found that during the first year after abandonment the fields were dominated by the winter annuals Erigeron annnus and E. canadensis. The second year the fields were dominated by Aster ericoides, a perennial, and the third year and for several years thereafter by Solidago canadensis, also a perennial. By the ninth year all of these early serai dominants had been either eliminated or had had their importance much reduced by the invasion of many other species.
Myxomycetes from the Everglades National Park and Adjacent Areas, I
(1973-11) Keller, Harold W.
A first list of 10 species of slime molds from the Everglades National Park is presented; this list includes the first report of Arcyria pomiformis from Florida. From areas outside the park 7 species new to Florida are reported: Comatricha subcaespitosa, Didymium listeri, Didymium ovoideum, Physarum galbeum, Stemonitis herbatica, Dictydiaethalium dictyosporum, Stemonitis inconspicua. The last 2 species were previously known, respectively, only from the type collection and only from the Netherlands and the British Isles. These additions bring to 132 the total number of Myxomycetes reported from Florida in the literature. Taxonomic notes are given for an undescribed species of Licea formerly identified and reported from Florida as Licea fimicola.
The Foliose and Fruticose Lichen Flora of the Ohio River Valley Between Gallipolis, Ohio, and Parkersburg, West Virginia
(1973-11) Showman, Ray E.
Lichens were surveyed in a relatively uncollected region composed of parts of Gallia, Meigs, Athens, and Washington Counties, Ohio, and parts of Mason, Jackson, and Wood Counties, West Virginia. A total of 87 species of foliose and fruticose lichens were recorded. New state records for West Virginia are Cetraria fendleri, Parmelia crozalsiana, P. flaventior, Parmeliopsis aleurites, Physcia adscendens, P. endococcinea, and P. lacinulata. Pseudevernia consocians was the only new species found in Ohio.
A Rapid Technique for the Detection of Nicotine in Developing Tobacco Seedlings
(1973-11) Wu, Pei-Hsing Lin; Sharp, William R.
A rapid and sensitive method for detecting alkaloids, in particular nicotine, from Nicotiana rustica tobacco seedlings up to 2 mm in length has been developed. Growing tissue is applied (squashed) directly onto silica gel plates for thin-layer chromotographic analysis. The sensitivity of this method permits the detection of quantities of nicotine as small as 0.4 microgram.
A Review and Analysis of the Utilization of Artificial Hearts in Mankind
(1973-11) Lanford, H. W.; Stickney, F. A.; Vasko, John S.
Research by the authors and expert opinion obtained from interview and questionnaire response predict the availability of an acceptable artificial heart for use in humans, and the development of proper medical procedures for its installation, within the next 15 to 20 years. Present medical advances are reducing the number of heart problems solvable by artificialheart implantation, but, because of increasing population, the actual number of those needing this operation may not decrease.
Autoradiographic Study of the Developing Chick Embryo Esophagus
(1973-11) Ramey, Barbara A.; Allenspach, Allan L.
Autoradiography was employed to examine the incorporation pattern of 3H-thymidine and 3H-uridine into presumptive stratified squamous epithelial cells and prospective degenerating cells of the chick embryo esophagus. The incorporation pattern of 3Hthymidine suggests that esophageal epithelial nuclei in the vesiculated region undergo interkinetic migration, synthesizing DNA at the basement membrane and moving to the free surface of the vesicles to complete the mitotic phase of the cell cycle. Incorporation patterns in prospective degenerating cells show a cessation of DNA synthesis correlating with the posterior-to-anterior degeneration gradient. No regionally specific pattern of 3H-uridine incorporation was observed.
Strontium Isotope Geochemistry of the Scioto River Basin and the Sr/Sr Ratios of the Underlying Lithologies
(1973-11) Steele, John D.; Pushkar, Paul
A survey has been made of the 87Sr/86Sr ratios and the rubidium and strontium concentrations in the different types of geologic materials underlying the Scioto River drainage basin in central Ohio. In the part of the basin north of the limit of maximum glaciation, these lithologies are mostly Paleozoic carbonate rocks and glacial deposits, as well as the soils that have developed on them. These materials have fairly low 87Sr/80Sr ratios of 0.708-0.715. South of the glacial limit, shales are abundant. These shales and the soils developed on them have much more radiogenic ratios of 0.703-0.745. Leaches of the shales and related soils, however, have ratios of only about 0.710-0.713. These data are in full accord with earlier published data and interpretations of the isotope geochemistry of strontium in the Scioto basin.
The Robust Conehead: Two Widespread Sibling Species (Orthoptera: Tettigoniidae: Neoconocephalus "Robustus")
(1973-11) Walker, T. J.; Whitesell, J. J.; Alexander, Richard D.
The coneheaded katydids formerly known as Neoconocephalus robuslus belong to two species: robustus (Scudder) and bivocatus n. sp. The two are sympatric in northeastern and midwestern United States, but robustus extends southward into Florida and Texas and westward into New Mexico. Populations of robustus in the Central Valley of California are apparently disjunct from the New Mexico populations and may be a result of recent introduction. Differences in calling song, width of the stridulatory area, and length of ovipositor are the most useful characters for separating the two species.
