The influence of tree cover and shade pattern upon the distribution of understory plants in ponderosa pine stands of central Oregon

Creator:: Robinson, Andrew Frederick, Jr.
Abstract:: Seven sites of uniform topography and soil were selected within a self perpetuating ponderosa pine forest found on the eastern flank of the central Oregon Cascades. These plots were located along a vegetational gradient caused mainly by an orographic rain shadow. Data gathered included density, frequency, and cover for all...

Distribution of understory species in relation to maximum and minimum tree influence in the montane forest of the Central Oregon Cascades

Creator:: Robinson, Andrew Frederick, Jr.
Abstract:: Twenty sites of uniform topography and soil were select ed in the montane forest found on the East flank of the Central Oregon Cascades. These sites were located along a vegetational gradient composed of five plant communities: Abies/Pachistima, Pinus/Ceanothus, Pinus Arctostaphylos-Purshia, Pinus/Purshia/Festuca, and Juniperus Festuca. An attempt was made to...

An investigation of the distribution of Nephtys caecoides in Yaquina Bay

Creator:: Morrison, George Edwin
Abstract:: A study was undertaken in Yaquina Bay, Oregon during the summer of 1964 to determine the distribution and the factors affecting the distribution of the polychaete worm, Nephtys caecoides, Hartman, 1938, in the estuary. This organism has a continuous distribution from offshore to a point approximately eight kilometers into the...

Bathyal and abyssal polychaetes (annelids) from the central coast of Oregon

Creator:: Hancock, Danil R.
Abstract:: Polychaete annelids from 48 benthic samples containing over 2000 specimens were identified. Samples were taken with either an anchor dredge or an anchor-box dredge from a 15 station transect (44° 39. 1'N) that ranges from 800 to 2900 meters in depth. Sediment subsamples were collected and analyzed for organic carbon...

Diversity and similarity of benthic fauna off Oregon

Creator:: Stander, Jeffrey M.
Abstract:: Samples of benthic organisms off the coast of Oregon, taken from depths varying from 50 to 2900 meters, have been analyzed in terms of diversity at a given station, and similarity and ecological distance to other stations. Estimates of epifauna abundance were also made. In the analysis an important distinction...

A method of improving power system transient stability using controllable parameters

Creator:: Mittelstadt, William Andrew
Abstract:: Controllable parameters in a power system include generator terminal voltage, generator input power and network admittances. These parameters can be controlled to damp mechanical rotor oscillation in the generators and thereby improve system transient stability. Explicit equations are derived in this thesis for the control of these parameters to introduce...

The nature of the pentose phosphate pathway in strains of Saccharomyces cerevisiae

Creator:: Salman, Howard Andrew
Abstract:: The catabolism of glucose by proliferating and resting cells of two strains of Saccharomyces cerevisiae has been examined, with respect to the nature and participation of concurrent glucose pathways by means of the radiorespirometric method. The nicotinamide nucleotide content, and nicotinamide nucleotide oxidase activities in these cells were also examined....
