Exploiting Hordeum vulgare subsp. spontaneum genetic resources : diversity analysis and germplasm development

Creator:: Matus, Iván Ariel
Abstract:: Wild barley (Hordeum vulgare subsp. spontaneum) could be a source of useful genes for improving cultivated barley. The useful genes present in Hordeum vulgare subsp. spontaneum may be new alleles at described loci, or these may be entirely new genes in the sense that there is limited allelic variation at...

The Oregon Coastal Subprovince, a new biogeographic subprovince for primary freshwater fishes in Oregon

Creator:: Kettratad, Jes
Abstract:: The Pacific Northwest has a relatively low diversity of primary freshwater fishes with most of the endemism and diversity in the Columbia River and Klamath River. However, the Oregon Coastal Subprovince defined as the coastal rivers from Miami River in the north to Sixes River in the south, has a...

Development and use of molecular tools in Fragaria

Creator:: Njuguna, Wambui
Abstract:: This dissertation describes the application and development of molecular tools that have great potential for use in studying variation in strawberry germplasm. The first study evaluated 91 microsatellite (simple sequence repeat, SSR) markers for transferability in 22 Fragaria species and their utility in fingerprinting octoploid strawberries. Out of the transferable...

Systematic, genomic, and transcriptomic analysis of mycoparasitic Tolypocladium species and their Elaphomyces hosts

Creator:: Quandt, C. Alisha
Abstract:: Fungi in the genus Tolypocladium are diverse in their host associations, but the predominant ecologies include parasites of the ectomycorrhizal genus Elaphomyces and pathogens of insects. The aim of this dissertation research is to examine the evolution of these fungi and their host associations. To accomplish this several lines of...

Riparian and adjacent upslope beetle communities along a third order stream in the western Cascade Mountain Range, Oregon

Creator:: Brenner, Gregory John
Abstract:: Monitoring wildlife habitats has become important to forest ecosystem management because it provides valuable information about the response of forests and their species to harvest practices, impacts from recreational use, conservation efforts, and natural and human-caused disturbances. Monitoring is a complex task that requires a variety of abiotic and biotic...

Systematics, phylogeny, and biogeography of the hysterangiales and related taxa (Phallomycetidae, Homobasidiomycetes)

Creator:: Hosaka, Kentaro
Abstract:: Monophyly of the gomphoid-phalloid clade was confirmed based on multigene phylogenetic analyses. Four major subclades (Hysterangiales, Geastrales, Gomphales and Phallales) were also demonstrated to be monophyletic. The interrelationships among the subclades were, however, not resolved, and alternative topologies could not be rejected statistically. Nonetheless, most analyses showed that the Hysterangiales...

Phylogeny, cospeciation, and host switching in the evolution of the ascomycete genus Rhabdocline on Pseudotsuga and Larix (Pinaceae)

Creator:: Gernandt, David S.
Abstract:: The relative role of cospeciation and host switching in the phylogenetic history of ascomycete foliar symbionts is addressed in the orders Leotiales and Rhytismatales, fungi associated predominantly with Pinaceae (Coniferales). Emphasis is placed on comparing the evolution of the sister genera Pseudotsuga and Larix (Pinaceae) with that of the pathogenic...

Phylogenetics, Biogeography, Morphological Variation, and Taxonomic Revision of Sandelia capensis (Cuvier 1829) (Anabantiformes: Anabantidae), a Freshwater Fish from the Coastal Streams of the Cape Region, South Africa

Creator:: Bronaugh, Whitcomb Meade
Abstract:: Accumulating human impacts on freshwater ecosystems have created a biodiversity crisis for freshwater fishes while conservation efficacy remains hampered by the Linnaean shortfall, the ignorance of many species that have yet to be discovered and described. The past discovery of most freshwater fish species was simply a matter of collecting...

Delimiting Species in the Mountaintops : New Trails for Studying Genomic Architecture and Sequencing Historical Specimens Uncover Hidden Diversity within the breve Species Group of Bembidion (Coleoptera : Carabidae)

Creator:: Sproul, John S.
Abstract:: Species are one of the foundational units upon which entire fields of scientific inquiry are built. Discovering and documenting the planet’s biodiversity remains one of the grand challenges of science. A proper conceptualization of species provides a critical framework for diverse fields such as biophysics, biochemistry, agriculture and pharmacology, and...

Crossing behavior, RAPD analysis and chlorophyll flourescence in relationship to the geographic adaption of birdsfoot trefoil (Lotus corniculatus L.)

Creator:: García de los Santos, Gabino
Abstract:: Birdsfoot trefoil (Lotus corniculatus L.) is a popular perennial, non-bloating forage legume used for pasture, hay and silage throughout the temperate regions of Europe, Asia Minor, North Africa and North and South America. It is regarded as the most morphologically and biochemically variable species in the genus. Research investigating the...
