Yosemite region nitrogen deposition and patterns in the composition of lichen communities

Creator:: Hutten, Martin
Abstract:: This dissertation describes patterns in epiphytic macrolichen community composition along a nitrogen deposition gradient in the Yosemite region of the Sierra Nevada in California. This region is part of the largest federal air quality Class 1 designated air-shed in the western United States, covering the entire crest of the Sierra...

Genetic variability in the eastern filbert blight pathosystem

Creator:: Osterbauer, Nancy K.
Abstract:: The heritability of resistance to eastern filbert blight, caused by Anisogramma anomala, in European hazelnut (Corylus avellana) was evaluated in the progeny of seven cultivars crossed in 12 combinations. Progeny produced by crossing 'VR6-28' with three susceptible cultivars segregated 1:1 for complete resistance to eastern filbert blight. Histograms of disease...

Bioindication of air quality in forests of northern and central California using epiphytic macrolichen communities

Creator:: Jovan, Sarah
Abstract:: The unifying purpose of this dissertation was to describe, model, and map relationships between epiphvtic macrolichen communities and air quality in Ibrests of northern and central California. First, multivariate analyses were used to subdivide the large study area into three model areas with similar climate, topography, and lichen communities: the...

Effects of current velocity, irradiance, and herbivory on algal assemblages in laboratory streams

Creator:: Steinman, Alan D.
Abstract:: Effects of current velocity, irradiance, and grazing on the biomass, taxonomic structure, physiognomy, and chemical composition of lotic algal assemblages were investigated. Four experiments, lasting 32 to 75 days, were conducted in laboratory streams to determine how these factors affect algal assemblages singly, and in concert with each other. Regardless...

Lichen response to the environment and forest structure in the western Cascades of Oregon

Creator:: Martin, Erin P.
Abstract:: Lichens are an important part of the biota in western Oregon forests, where they perform valuable ecological roles and contribute significantly to biodiversity. Lichens in western Oregon are threatened by a number of factors including air pollution and land use practices. If we wish to maintain the persistence of lichens...

Plastome phylogenomics in the genus Pinus using massively parallel sequencing technology

Creator:: Parks, Matthew Benjamin
Abstract:: This thesis summarizes work completed over the previous four years primarily focusing on chloroplast phylogenomic inquiry into the genus Pinus and related Pinaceae outgroups using next-generation sequencing on Illumina platforms. During the time of our work, Illumina sequence read lengths have essentially been limited to 25 to 100 base pairs,...

Taxonomy and host specificity of the genus Agrobacterium

Creator:: Anderson, Arthur Robert
Abstract:: One hundred seventy-eight Agrobacterium isolates, 120 United States (U.S.), 26 Australian and 32 of miscellaneous origin, were characterized for their reactions to 20 biochemical and physiological tests. Isolate pathogenicity and degree of host specificity, utilization of nopaline and octopine, and sensitivity to agrocin-84 also were determined. The U.S. isolates were...

Isolation and identification of dahlia viruses

Creator:: Lawson, Roger Harold
Abstract:: Three viruses were isolated from dahlias using a modification of Yarwood's leaf-disc method of inoculation. Two of these isolates have been reported previously in dahlias. In addition, a fourth virus was isolated using a liquid-nitrogen transmission technique. Dahlia virus isolate 1 possessed host range and thermal inactivation properties similar to...
