A fistful of Astragalus : phenotypic and genotypic basis of the most taxon rich species in the North American flora

Creator:: Knaus, Brian J.
Abstract:: The study of the infra-specific ranks (i.e., subspecies and variety) can be considered the study of the process of speciation. Astragalus lentiginosus Douglas ex Hooker (Fabaceae) is the most taxon rich species in the U.S. flora currently including 40 taxonomic varieties. These varieties were described using traditional taxonomic methods primarily...

A systematic study of Lathyrus vestitus Nutt. ex T. & G. (Fabaceae) and allied species of the Pacific Coast

Creator:: Broich, Steven L.
Abstract:: Eight species of Lathvrus (Fabaceae, Faboideae) endemic to the Pacific Coast of North America were the subject of a systematic investigation. Taxa studied included Lathvrus vestitus, Nutt. ex T. & G., L. laetif lorus Greene, L.. iepsonii Greene, £,. splendens Kellogg, L. polvphvllus, Nutt. ex T. & G., L. holochlorus...

A two-component regulatory system controlling antibiotic production by Pseudomonas flourescens Pf-5

Creator:: Corbell, Nathan
Abstract:: Tn5 mutagenesis of apdA (for antibiotic production) and deletion of gacA (for global antibiotic and cyanide) resulted in the same pleiotropic phenotype in Pseudomonas fluorescens (i.e. production of an array of secondary metabolites including the antibiotics pyrrolnitrin, pyoluteorin, and 2,4-diacetylphloroglucinol as well as a tryptophan-side-chain oxidase, hydrogen cyanide, and an...

Advances in molecular systematics of clavicipitaceous fungi (Sordariomycetes: Hypocreales)

Creator:: Kepler, Ryan M.
Abstract:: Historical concepts of Clavicipitaceae have included a broad range of species that display diverse morphologies, ecological modes and host associations. When subjected to multigene phylogenetic investigation of evolutionary history, the family was found to be polyphyletic, largely driven by diversity in the genus Cordyceps, previously containing over 400 taxa. The...

Amino acids in tissues from healthy and crown gall infected Kalanchoe pinnata

Creator:: Harris, Raymond Gene
Abstract:: Crown gall infected and healthy Kalanchoe pinnata (Lam.) Persoon plants were analyzed for soluble amino acids. Specifically the amino acids in young leaf, mature leaf, stem, root, and gall tissues were quantitatively measured. The plants were inoculated with the bacterium, Agrobacterium tumefaciens (Smith and Townsend) Conn., on one side of...

An analysis of montane forest vegetation on the east flank of the central Oregon Cascades

Creator:: West, Neil E.
Abstract:: Montane forest vegetation as it occurs on the east flank of the central Oregon Cascades has provided excellent conditions for a "natural experiment" in the use of various methodologies in studying vegetational distribution. This "experiment" has reflected on some theory and practice for the discipline of plant synecology. Detailed descriptions,...

An investigation of vegetation : hydrology interactions in watershed 1 at the H.J. Andrews Experimental Forest

Creator:: Bredensteiner, Kim C.
Abstract:: For management purposes, it would be useful to be able to predict streamflow response to forest practices in small, unmonitored basins. The primary objective of this study is to investigate the influence of early successional vegetation on summer streamflow levels. The long-term data records from watershed 1 at the H.J....

Anatomical changes in the secondary phloem of grand fir (Abies grandis (Dougl.) Lindl.), induced by the balsam woolly aphid (Adelges piceae Ratz.)

Creator:: Saigo, Roy Hirofumi
Abstract:: The balsam woolly aphid (Adelges piceae Ratz.) feeds by inserting its stylets intra- and intercellularly into the cortex or outer phloem of the true firs. While feeding, the aphid injects into the bark an unknown stimulatory substance which affects the adjacent cortical parenchyma cells, the activity of the vascular cambium...

Benthic algal communities of the Metolius River

Creator:: Sherman, Barbara Jane Powell, 1938-
Abstract:: Samples of benthic algae were collected from the Metolius River of central Oregon at two-week intervals between April 15, 1967 and March 9, 1968. Species of filamentous algae and diatoms present were recorded for every sampling station on each sampling date. Permanent mounts of diatom frustules were prepared. This sampling...
