Effects of temperature and other abiotic and biotic factors on development and survival of the immature stages of the alfalfa leafcutting bee, Megachile pacifica (Panzer) (=rotundata (F.)) (Hymenoptera:Megachilidae)

Creator:: Undurraga O., Jaime M.
Abstract:: Larval mortality of leafcutting bee, Megachile pacifica (Panzer) (= rotundata (F.)), is high, usually exceeding 50%. Parasites and predators are not a limiting factor in the survival of the progeny. The disease chalk brood has been an important mortality factor since 1974. Inadequate food supply, pollen and nectar, may affect...

Studies on canker in European filbert caused by Anisogramma anomala

Creator:: Postman, Joseph D.
Abstract:: Anisogramma anomala causes a stem canker of filberts, Corylus avellana. This disease became a threat to the main U.S. filbert growing region when it was introduced into the Pacific Northwest around 1968. Various methods of artificially inoculating filbert trees and seeds were explored. Less than 1% of potted filbert trees...

Ethylene production from cultures of Cylindrocladium and from Cylindrocladium-infected azalea leaves

Creator:: Axelrood, Paige Ellen
Abstract:: Ethylene was produced by Cylindrocladium floridanum and C. scoparium in culture. Production was methionine dependent and maximal during the active growth phase of the fungus, beginning shortly after spore germination. More ethylene was produced sooner by C. floridanum than C. scoparium. Ethylene was produced by Cylindrocladium both from active mycelium...

Factors affecting stand establishment and yield of meadowfoam (Limnanthes alba Benth.)

Creator:: Nyunt, San
Abstract:: Germination of meadowfoam (Limnanthes alba Benth.) seed is inhibited by warm soil temperatures. This has led to recommendations for planting from early to mid-October when soil temperatures are below about 15°C. Objective data on the effects of planting date on stand establishment and yield are not available. These studies were...

Accelerating the convergence of the k-eigenvalue problem using a coarse mesh finite differencing scheme in cylindrical geometry

Creator:: Hummel, Andrew J.
Abstract:: Reactor modeling is largely limited by the computational time required to perform accurate full core calculations. There are many different methods and techniques employed in different reactor simulation codes, but properly modeling all of the physics that takes place in the system requires extensive computational effort. The Coarse Mesh Finite...

Cannabis and Emotion Processing: A Review of Behavioral, Physiological, and Neural Responses

Creator:: MacKenzie, Alyssa A.
Abstract:: With cannabis use increasing globally, it is important to understand its acute and chronic impacts on human physiology and behavior. It is proposed that cannabis use is linked to impairments in emotion processing, and brain regions that underlie these processes. The purpose of this review paper is to provide the...

Into the Garden: Environmental Education and Resources for K-5

Creator:: Smith, Amira R.
Abstract:: This thesis aims to address barriers that K-5 educators face when implementing environmental education in classrooms. An in-depth study of the history of environmental education in the United States identifies primary barriers and issues. Focusing specifically on garden education programs, six lesson plans for K-5 were created to address the...

Temporal Variation in Humpback Whale (Megaptera novaeangliae) Demographics Along the Western Antarctic Peninsula

Creator:: Pallin, Logan J.
Abstract:: Humpback whale populations in Antarctica are recovering after intensecommercial whaling in the 20th century. Along the Western Antarctic Peninsula (WAP)this recovery is occurring in an environment that is experiencing the fastest warming ofany region on the planet. To begin to understand the dynamics of this recovery undersuch dramatic climate change,...

Oregon State University Student Electoral Participation, 2006-2010

Creator:: Bene, Heather T.
Abstract:: This study examines student voting at Oregon State University (OSU) – Oregon’s public, land-grant university – in state elections from 2006-2010. The National Voter Registration Act of 1993 (NVRA), Oregon Senate Bill 951 (2007), and Oregon House Bill 2880 (2011) seek to increase university student voting. In particular, SB 951...
