    Brief Note: The Occurrence of the Exotic Daphnia lumholtzi in Grand Lake St. Marys, Ohio
    (1996-09) Hiskey, R. M.
    An exotic Daphnia, Daphnia lumholtzi is reported from Grand Lake St. Marys, in west-central Ohio. This species was first reported in the USA in Texas, and 16 other primarily southern states. Its native habitat is east Africa, south-west Asia, and Australia. D. lumholtzi has appeared in zooplankton samples from Grand Lake St. Marys in the late summer and fall yearly since its first appearance in the fall of 1993.

    Brief Note: Vesicular-Arbuscular Mycorrhizal Status of Spring Ephemerals in Two Ohio Forests
    (1996-09) DeMars, Brent G.
    Nineteen spring ephemerals (7 monocots and 12 dicots) were surveyed for vesicular-arbuscular mycorrhizae (VAM) in two Ohio forests during spring 1993 and 1994. Eleven of the nineteen species sampled displayed VAM development which was consistent between years and sites, except for Cardamine concatenata (Brassicaceae). Patterns of VAM occurrence primarily reflected the taxonomic classification of the sampled species. In this study, all monocots sampled were mycorrhizal, while only 25% of the dicots developed VAM relationships. The occurrence of VAM in the dicots primarily reflected their taxonomy as well. All Ranunculaceae species were mycorrhizal while those in the other five dicot families were not.

    Optimal Human Posture-Analysis of a Waitperson Holding a Tray
    (1996-09) Huston, Ronald L.; Liu, Yung Sheng
    This paper explores optimal human posture for burden bearing. The optimization is based upon a uniform muscle stress criterion. This criterion, when used with the governing mechanical equations, removes a redundancy thus enabling a solution of the equations. The paper then presents an application with a waitperson holding a tray. The results are seen to be consistent with observed practices. Implications for dynamic analysis and for optimal performance are discussed.

    Water Quality Distance Education Program for County Extension Agents
    (1996-09) Mancl, Karen M.
    Few educational opportunities exist to teach rural homeowners water supply management. A correspondence program entitled Quality Water for Home and Farm was designed to prepare a group of teachers to fill the gap. The program objective was to train county extension agents in water quality and management principles and how to use educational materials to teach farmers and homeowners those principles through a distance education training program. Twenty six of the 72 county and district extension agents (36%) who enrolled completed the correspondence program. Participants gained increased understanding of water quality principles in 20 major areas.

    The Nature of Student Science Projects in Comparison to Educational Goals for Science
    (1996-09) Schneider, Rebecca M.; Lumpe, Andrew T.
    The objective of this research was to determine if student science projects in Ohio were meeting educational goals for science as recommended by the American Association for the Advancement of Science, the National Science Teachers Association, and the Ohio Department of Education. In addition, five methods were examined to determine if each had a positive effect on science projects in meeting these educational goals. Teachers from the Diocese of Toledo with students completing science projects in The Ohio Academy of Science's District 2 were asked to rate projects for each aspect of eight educational goals for science defined by this study. Science projects were rated overwhelmingly and consistently positive on each goal. Modeling of skills in the classroom was found to be significantly linked to six of the eight goals for science education. In addition, there was evidence to suggest that participating at a district science fair and supportive help also improved these ratings.

    Dieback in the Native Shrub, Lindera benzoin: A Subtle Effect of Forest Fragmentation
    (1996-09) Medley, Kimberly E.
    I report on a documented dieback in spicebush, Lindera benzoin, after the winter of 1993-1994 in two mature deciduous forest stands in southwestern Ohio. The study compares differences between 67 ha Hueston Woods and 5.2 ha Kramer Woods and examines spatial patterns of decline in Kramer Woods. Local daily minimum temperatures in January 1994 were among the coldest on record since 1889. The shrub is one of the most important understory species in both forests, but relative basal area measures of dead stems were significantly less in Hueston Woods (mean = 54% of the total) than in Kramer Woods (86%). Spicebush shows a clustered distribution in Kramer Woods, present on a flat upland area along the northern edge. Only two points with spicebush showed no decline and they are >60 m from the north edge and along streams. Dieback was up to 100% for plots with mean shrub heights >1.5 m, resulting in a significant understory gap. These findings identify important differences between and within forest patches that appear attributable to fragmentation effects. Forest conservation plans need to better capture a diversity of topographic settings or incorporate buffer zones along edges to better ensure the protection of native flora in human-dominated landscapes.
