A study on the effects of enhanced pCO2 on open ocean diazotrophic assemblages

Creator:: Gradoville, Mary Rose
Abstract:: Biological di-nitrogen (N₂) fixation is a key process in open-ocean ecosystems, where the new nitrogen (N) provided by marine diazotrophs can support a large fraction of primary productivity and carbon (C) drawdown. Recent laboratory studies have shown that elevated pCO₂ enhances the rate of N₂ fixation by select laboratory isolates...

Ecology and Environmental Controls of Two Keystone Groups of Oceanic Microorganisms : Diazotrophs and Pathogenic Vibrio

Creator:: Gradoville, Mary Rose
Abstract:: Marine bacteria play vital roles in every niche of the ocean, from small-scale symbioses to large-scale productivity and the regulation of Earth’s climate. Recent advances in molecular tools now allow us to probe the genetic potential of entire microbial communities. The next step is linking these diverse communities to the...

Genetic and environmental differences in age at first estrus and in wool and lamb production of crossbred ewe lambs

Creator:: Cedillo, Rose Mary
Abstract:: Genetic and environmental factors affecting age of first estrus, wool production, reproduction and lamb production were examined in eight groups of crossbred ewe lambs from two birth years. The 399 ewe lambs whose first year production was analyzed were from eight crossbred groups resulting from mating North Country Cheviot, Dorset,...

Fertilization of 2-0 ponderosa pine seedlings in the nursery and field : morphology, physiology, and field performance

Creator:: Gleason, John F.
Abstract:: Two-year-old ponderosa pine (Pinus ponderosa Laws.) from two seed sources were grown at two nurseries. The Fremont seed source was raised at Bend and Stone Nursery; the Ochoco was grown at only the Bend Nursery. The seedlings were fertilized in late September-early October with nitrogen (N) or nitrogen plus potassium...

Frost hardiness of Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco) seedlings raised in three nurseries

Creator:: Schuch, Ursula K.
Abstract:: Two-year-old Douglas-fir [Pseudotsuga menziesii (Mirb.) Franco] seedlings of two seed sources raised in three nurseries in Oregon and Washington were tested for differences in frost hardiness from September 1985 to March 1986. The objective of the study was to determine whether nursery location had an influence on seedling acclimation, deacclimation...

In the words of a woman

Creator:: Rose, Kerin G.
Abstract:: I am a woman who writes. I am a writer who is a woman. In the Words of a Woman is an exploration of how these two facts of my life merge and influence each other. It is a work written to mediate between the supposed dichotomies of creative and...

Physiological Response of Crocosphaera watsonii to Enhanced and Fluctuating Carbon Dioxide Conditions

Creator:: Gradoville, Mary R., White, Angelicque E., and Letelier, Ricardo M.
Abstract:: We investigated the effects of elevated pCO₂ on cultures of the unicellular N₂-fixing cyanobacterium Crocosphaera watsonii WH8501. Using CO₂-enriched air, cultures grown in batch mode under high light intensity were exposed to initial conditions approximating current atmospheric CO₂ concentrations (~400 ppm) as well as CO₂ levels corresponding to low- and...

An analysis of the diagnostic and perscriptive expertise of Level II and Examiner downhill ski instructors

Creator:: Young, Ben (Ben Leonard)
Abstract:: For coaches to qualitatively analyze the performance of sport skills as executed by their students, they must possess an internal image of the desired skill against which to make comparisons (Hoffman, 1983; Pinheiro & Simon, 1992). Leas and Chi (1993) have indicated that there are differences between novice and expert...
