  • 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...

  • 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...

  • Identified Influences on Second Generation Latina/os on Their Pathway Through Community College

    Creator:
    Jaime-Diaz, Jesus
    Abstract:
    The purpose of this study is to determine factors that encourage second generation Latina/os to obtain a community college education. A critical qualitative ethnography focused on "Testimonio" was used in conducting this study. The key findings were formulated around three critical research questions. In relation to each research question, three...

  • Neural gene expression profiling in chinook salmon (Oncorhynchus tshawytscha) of alternate run times

    Creator:
    Bernier, Jeremiah C.
    Abstract:
    Chinook salmon (Oncorhynchus tshawytscha) display the greatest variability of return times to freshwater of all Pacific salmon. Differential return times to freshwater have segregated populations of Chinook into two broad types or runs, fall and spring, named for the time of year in which they migrate to freshwater. Migration time...
