The influence of behavior and water requirements on the distribution and habitat selection of the gray-tailed vole (Microtus canicaudus) with notes on Microtus townsendii

Creator:: Pearson, John Philip
Abstract:: Microtus canicaudus Miller, the gray-tailed vole, was studied in the field and laboratory in order to clarify aspects of the relationship of this species to its habitat. All trapping and sampling was done on permanent pasture land in the William L. Finley National Wildlife Refuge 12 miles south of Corvallis,...

A quantitative method for using an inventory of the soil and water resources of the state of Oregon to determine human population carrying capacities for two acceptable qualities of life

Creator:: Karr, Don John
Abstract:: A method was developed for converting the food producing capabilities of Oregon's soils to numerical data from which state and county carrying capacities for human populations could be calculated. Another method was developed for converting the needs for housing and related support construction to numerical data which would consume cultivated...

Some aspects of the sulfur cycle in tidal flat areas, and their impact on estuarine water quality

Creator:: Ramm, Alan Edmund
Abstract:: A conceptual model of the tidal flat system, emphasizing the sulfur cycle was presented. Measurements were made of the vertical distribution within tidal flat deposits of total aerobic and sulfate reducing bacteria, total sulfides, redox potential, volatile solids, and particle size. Variations in dissolved oxygen and free sulfides in the...

Metabolic adaptations of the marine gastropod Thais emarginata

Creator:: Sweat, Sister Jean
Abstract:: Thais emarginata is a gastropod which inhabits the midlittoral zone of the intertidal region. Oxygen consumption of high-level and low-level organisms was determined at various seasons of the year over an experimental temperature range of 5 to 20° C. No significant difference in respiratory rate between separate populations of high-level...

An analysis of the vegetation of Abbott Creek Natural Area, Oregon

Creator:: Mitchell, Rod
Abstract:: Abbott Creek Natural Area is a 2600 acre research area of the Mixed-Conifer forest type. This study delineated plant association units within the area, and demonstrates the use of the computer program SIMORD as a tool in the definition of such associations. One hundred fourteen sites were sampled by a...

Applications of Holographic Optical Tweezers: Multiplexed Fluorescence Spectroscopy and the Micromechanics of Type-I Collagen

Creator:: Cibula, Matthew A.
Abstract:: The development and some applications of holographic optical tweezers (HOT) are presented. Our HOT system uses a spatial light modulator (SLM) to control the location and properties of the optical trap. We have developed a method for optimizing the diffraction efficiency of a SLM that can be applied in situ...

A rubidium atomic funnel

Creator:: Swanson, Thomas B.
Abstract:: A low velocity, low temperature beam of atoms is produced from a two-dimensional magneto-optic trap known as an atomic funnel. The funnel provides simultaneous spatial and velocity compression of atoms and will provide a source for a three-grating atomic interferometer. Rubidium atoms from an oven are slowed by chirped cooling...

Laser cooling and trapping with electronically stabilized grating-feedback diode lasers

Creator:: Silva, Nancy J.
Abstract:: We have developed simple and inexpensive laser systems using grating-feedback diode lasers with electronic feedback to the injection current. These grating-feedback lasers can be continuously scanned up to 10 GHz and have a linewidth of 150 kHz. The three electronic frequency-stabilization systems we developed use polarization spectroscopy, etalon transmission and...

Low-velocity matter wave source for atom interferometry produced by Zeeman-tuned laser cooling and magneto-optic trapping

Creator:: Mayer, Shannon K.
Abstract:: A continuous, low-velocity, nearly monochromatic atomic beam is created using laser cooling and two-dimensional magneto-optic trapping. Rubidium atoms from an effusive oven are slowed and cooled using Zeeman-tuned slowing. The scattering force from a counter-propagating, frequency-stabilized diode laser beam is used to decelerate the thermal beam of atoms to a...
