Soil moisture depletion trends under five plant species present on the Douglas-fir clear-cuts of Mary's Peak, Oregon

Creator:: Drew, Stephen Ernest
Abstract:: Soil moisture depletion trends under five plant species growing on the clear-cuts of the Marys Peak Watershed near Corvallis, Oregon, were followed during the summers of 1963 and 1964. The species were Holcus lanatus, Lotus crassifolius var. subglaber, Gaultheria shallon, Berberis nervosa, and Acer circinatum; and were dominant plants of...

A study of radar precipitation echo as influenced by Marys Peak

Creator:: Sears, James W.
Abstract:: The Weather Radar Set An/CPS-9 at McCulloch Peak, Oregon, provided data of changes in radar precipitation echo patterns in the vicinity of Marys Peak. Echo heights studied from data collected on 14 March 1963 averaged nearly the same upwind, directly over Marys Peak, and downwind. For the data of 28...

The phytosociology of some vine maple communities in the Marys Peak watershed

Creator:: Anderson, Howard George
Abstract:: A study was undertaken in the Marys Peak watershed with the following objectives. First, a classification of the major plant communities was carried out. Second, some of the ecological features of Acer circinatum that account for its distribution within these communities were determined. The following plant communities are described: Corylus...

Biological and ecological aspects of the black flies of the Marys River drainage system (Diptera: Simuliidae)

Creator:: Speir, Jon Allen
Abstract:: Members of the family Simuliidae were studied in a single, confined drainage system. In addition to determining the occurrence and distribution of the species present, biological and ecological observations were made. Specific measurements and observations were accomplished to determine as much as possible about the habitat specificity and life cycle...

Purification and kinetics of gelatinase obtained from an obligately psychrophilic marine vibrio

Creator:: Weimer, Mary Stepahin
Abstract:: Optimum growth of Marine Psychrophile 41 (MP-41) an obligately psychrophilic marine vibrio, occurred at 18 C and pH 8.0 to pH 8.3. Twenty eight-fold purification of gelatinase from this organism was effected by ammonium sulfate fractionation and column chromatography on Sephadex G-200 gel. The effects of temperature, pH, pressure, and...

Early stages in plant succession on Douglas fir clearcuts on the Mary's Peak watershed near Corvallis, Oregon

Creator:: Brown, Eugene Allen
Abstract:: This study has been concerned with the patterns of vegetative changes which occur during the first five years following logging and burning on Douglas-fir clear cuts. Knowledge of the successional sequence in the coastal forests of western Oregon is of primary importance to those concerned with the management of this...

Temperature-salinity effects on net protein synthesis and viability of Vibrio marinus mp-1, an obligately psychrophilic marine bacterium

Creator:: Cooper, Mary Faith
Abstract:: The relationship of temperature and salinity to protein synthesis was determined for cells of Vibrio marinus, MP-1. Protein synthesis was measured by the incorporation of radioactive proline into hot trichloroacetic acid precipitable material. At all salinities protein synthesis occurred at 15°C and 20°C but not at 25°C. The critical temperature...

Solvent selectivity of several organoclay complexes

Creator:: Nee, Mary
Abstract:: Six organoclay complexes have been studied in terms of their selective adsorption from binary solutions of methanol and toluene. Analyses are based on differential refractometry methods. The isotherms were of the usual "S" type. The crossover points reveal trends in the organophilic nature of the interlaminar surfaces in these clay...
