The effects of prescribed burning on mule deer wintering at Lava Beds National Monument

Creator:: Schnoes, Roger Seibert
Abstract:: Field studies were conducted during January, February and March of 1976 and 1977 to evaluate the effects of a prescribed burning program on mule deer at Lava Beds National Monument. Visual observation, radio-telemetry and pellet-group plots were utilized to investigate deer distribution, food habits, movement patterns and behavioral responses to...

Photobiological hydrogen production from the cyanobacterium Synechocystis sp. PCC 6803 encapsulated in sol-gel processed silica

Creator:: Dickson, David J.
Abstract:: Photobiological hydrogen production from live cells of the cyanobacterium Synechocystis sp. PCC 6803 encapsulated in silica gel was investigated. Hydrogen is a dense energy carrier with potential to reduce dependence on fossil fuels, provided a renewable and sustainable means of production can be achieved. Under certain conditions, Synechocystis sp. PCC...

Metabolic engineering of cyanobacteria to optimize photobiological hydrogen production

Creator:: Luterra, Markael
Abstract:: Photobiological hydrogen production -- the use of photosynthesis to split water into hydrogen and oxygen -- presents an opportunity for efficient and large-scale solar biofuel development. One of the major challenges in this area is competition for reductant between the hydrogen-evolving hydrogenase enzyme and other metabolic pathways. In this work...

Estimation of leaf area index and simulation of evapotranspiration for intensively managed Douglas-fir forests

Creator:: Rogers, Nicole S.
Abstract:: Understanding the tradeoff between water use and productivity is critical for modeling growth of intensively managed Douglas-fir forests in the Pacific Northwest. Evapotranspiration is closely linked to carbon dioxide intake during the process of photosynthesis. However, summer drought characterizing the growing season in this region imposes a limit on carbon...

Optimization of environmental conditions and electron flow for enhanced hydrogen production by cyanobacterial species Synechocystis sp. PCC 6803

Creator:: Burrows, Elizabeth H.
Abstract:: Many conditions affecting hydrogen (H₂) production by the cyanobacterium, Synechocystis sp. PCC 6803, were optimized to yield maximum H₂ accumulation. Biological H₂ production from photosynthetic species is a promising form of renewable energy since an abundant supply of sunlight hits the Earth every day, and photosynthetic bacteria can harness this...

Foraging ecology of prairie falcons in northern California

Creator:: Haak, Bruce A.
Abstract:: Nine Prairie Falcons (Falco mexicanus) were radio-tagged in northern California during the spring and summer of 1976 and 1977 to study foraging behavior. The mean home range size for 3 males was 227.8 km²; largest portions of the home range were used during the incubation period. Shifts in foraging areas...

The effects of prescribed burning on small mammal communities in Lava Beds National Monument, California

Creator:: Frenzel, Richard Wilmarth
Abstract:: The effects of prescribed burning on the abundance, species composition, and reproduction of small mammals were studied over a one year period. Two burn areas were studied, one in sagebrush/ bunchgrass and one in cheatgrass. The short-term effects were studied using monthly mark-recapture trapping on two treatment and two control...

A comparison of the relative effectiveness of teaching composition by closed-circuit television and by conventional classroom procedures

Creator:: Patty, Austin Horace
Abstract:: This study was designed to test the relative effectiveness of teaching Writing 111 at Oregon State University by closed-circuit television as compared with conventional classroom procedures; the hypothesis was that the students taught by television (the experimental group) would achieve as well as the students taught in conventional classrooms (the...

Make it Rain : A Lagrangian Approach to Investigate Land Surface Controls on Moisture Recycling in the Columbia River Basin

Creator:: Tai, Leah Chung-Mei
Abstract:: Linkages between land use and its influence on the atmosphere have been a long-standing research area. For example, what is the impact of irrigated agriculture on downwind rainfall? Global-scale models show that moisture recycling is an important source of water for inland regions around the world, but they do not...
