  • Host selection, reproductive biology, host-specific development and mortality of the codling moth, Cydia pomonella (L.) (Lepidoptera: Torticidae), in apple and pear

    Creator:
    Marti, Santiago Marti
    Abstract:
    The biology and behavior of the codling moth, Cydia pomonella (L.), was studied to determine factors responsible for differences in susceptibility to moth damage among apple and pear cultivars. In release experiments, codling moth adults were intercepted in significantly greater numbers in host (apple, pear) than in non-host (maple) trees,...

  • Factors affecting bird counts and their influence on density estimates

    Creator:
    McCracken, Marti L.
    Abstract:
    Variable area surveys are used in large geographic regions to estimate the density of birds distributed over a region. If some birds go undetected, a measure of the effective area surveyed, the amount of area occupied by the birds detected, is needed. The effective area surveyed is determined by observational,...

    Creator:
    O'Dell, Marti
    Abstract:
    Since the passage of the Education for All Handicapped Children Act in 1975, a number of common problems have emerged. Primarily they involve the difficulties both experienced and created by public schools attempting to fulfill the federal mandate to provide students with disabilities an appropriate public education. The purpose of...

  • Integrating solute transport, metabolism and processing in stream ecosystems

    Creator:
    González Pinzón, Ricardo A.
    Abstract:
    After three decades of active research coupling hydrology and stream ecology, the connection among solute transport, metabolism and processing is still unresolved. These knowledge gaps obscure the functioning of stream ecosystems and how those ecosystems interact with other landscape processes. We must resolve these challenges to wisely manage water resources,...

  • Molecular characterization of criniviruses and ilarviruses infecting strawberry

    Creator:
    Tzanetakis, Ioannis E.
    Abstract:
    Pallidosis is a disease of strawberry identified in 1957 with an unknown etiology. Two previously uncharacterized viruses in strawberry, Strawberry pallidosis associated virus (SPaV) and Beet pseudo-yellows virus (BPYV), have been found associated with disease symptoms. The complete nucleotide sequence of both viruses was determined and molecular detection protocols developed....

  • Height-related trends in structure and function of Douglas-fir foliage

    Creator:
    Woodruff, David R.
    Abstract:
    This dissertation investigated the impacts of tree height upon a range of physiological and structural characteristics of Douglas-fir foliage; relationships between structural and functional trends with height; and compensatory mechanisms that mitigate height-related growth constraints. Height-related trends in foliar physiological and anatomical characteristics were examined both within trees as well...

  • Analysis of the international demand for Brazil nuts

    Creator:
    Paez, Paulo Brasil
    Abstract:
    The basic objective of this investigation was to identify and to examine factors determining the volume of imports of inshell and shelled Brazil nuts in major importing countries: the United States, the Federal Republic of Germany and the United Kingdom. The approach followed involved the construction and analysis of an...

  • Development and broad application of a mass spectrometry based metabolomics platform

    Creator:
    Kirkwood, Jay Steven
    Abstract:
    Metabolomics is a comprehensive analysis of small molecules, or metabolites, in a system. Metabolomics is a hypothesis-generating experiment and offers an unbiased analysis of cell metabolism that can aid in the understanding of fundamental biological processes. Metabolomics is widely and broadly applicable in the biological sciences and has been used...

  • Hydrological and biogeochemical dynamics of nitrate production and removal at the stream – ground water interface

    Creator:
    Zarnetske, Jay P.
    Abstract:
    The feedbacks between hydrology and biogeochemical cycling of nitrogen (N) are of critical importance to global bioavailable N budgets. Human activities are dramatically increasing the amount of bioavailable N in the biosphere, which is causing increasingly frequent and severe impacts on ecosystems and human welfare. Streams are important features in...

  • Multiple functions of a proteinase in closterovirus life cycle

    Creator:
    Peng, Chih-Wen
    Abstract:
    More than half of the recognized genera of positive strand RNA viruses employ polyprotein processing as one of the strategies for their genome expression. Normally, this processing is mediated by virus-encoded proteinases that belong to the trypsin-like or papain-like family. In particular, papain-like, leader proteinases were found in diverse families...
