Consequences of coumaphos and Varroa destructor on drone honey bee sperm quantity

Creator:: Delaney, Deborah Anne
Abstract:: The number of drones and genetic diversity among drones are essential components to a well mated queen. Varroa destructor preferentially parasitizes drone brood, and is thought to be responsible for the loss of feral populations that once provided additional drones for honey bee mating areas. It is necessary to use...

Spatial Patterns of Soil Moisture and the Relative Importance of Atmospheric Water Demand Versus Soil Moisture Availability in Limiting Late-summer Growth of Douglas-fir Under a Changing Climate

Creator:: Jarecke, Karla M.
Abstract:: The rapid pace of climate change is increasing tree mortality and highlighting the need to improve the mechanistic understanding of plant function under increased water stress. However, the processes that control soil moisture availability in steep mountainous terrain are poorly understood, as are the relative effects of atmospheric and soil...

Making the Connection: Linking Stress Physiology of Juvenile Northern Spotted Owls to Environmental Variation and Long-term Survival

Creator:: Mikkelsen, Ashlee J.
Abstract:: The northern spotted owl (Strix occidentalis caurina; spotted owl) is of conservation concern and endemic to mature forests of the Pacific Northwest. Adult survival has a strong effect on population growth rate, but juvenile survival and recruitment are also important components of population change. Despite the importance of this life...

Linear theory of roll instabilities in the ocean surface layer

Creator:: Duncombe, Jenessa R.
Abstract:: This thesis describes the results of a linear stability analysis conducted on a simulated wind-forced ocean front. The ocean surface boundary layer regulates exchanges between the ocean and atmosphere, and the presence of turbulence in the surface layer can greatly impact climate and ocean life. Past research has shown that...

Estimation of Population Age Structure, Detection Probability, and Density of Red Tree Voles in Oregon

Creator:: Marks-Fife, Chad A.
Abstract:: Red tree voles (Arborimus longicaudus) are a unique species of Arvicoline rodent found in western Oregon and northwest California. Their preferred habitat is mature and old-growth coniferous forest dominated by Douglas-fir (Pseudotsuga menziesii). Tree voles are an important prey item for northern spotted owls and many other predators, but are...

Communicating oceanographic research through film : the role of film in helping scientists develop and meet their broader impacts goals

Creator:: Madlener, Saskia D.
Abstract:: Funding agencies, specifically the National Science Foundation (NSF), are placing particular emphasis on the societal relevance and broader applications of scientific research, otherwise known as Broader Impacts (BIs). Scientists are required to address the BIs merit review criterion in their research proposals or they will not get funded. However, many...

Managing our urban forest : what do officials and managers think and need? A case study from the Portland-Vancouver metropolitan area

Creator:: Driscoll, Abbey N.
Abstract:: Urban forests are fundamental to the health and sustainability of urban communities. In 2012, the U.S. Forest Service launched the Vibrant Cities, Urban Forests: A National Call to Action initiative which posed a variety of recommendations to advance urban forest management and programs throughout the country. In response to that...

The use of LiDAR to identify forest transportation networks

Creator:: Beck, Storm J. C.
Abstract:: The production of high value non-conventional products, such as long utility poles; or the production of low value bulky products, such as chips or grindings; provide opportunities for forest owners to increase value from their forests. The transport of these products requires the use of specialized trucks and trailers. However,...

Evaluating "nuisance" beaver relocation as a tool to increase coho salmon habitat in the Alsea Basin of the central Oregon Coast Range

Creator:: Petro, Vanessa M.
Abstract:: Many stakeholders involved with stream restoration in the Pacific Northwest have discussed the potential benefits of using beaver dam construction activities (Castor canadensis) as a management tool to improve degraded stream habitat for anadromous salmon species. In addition, there has been growing interest in using nuisance beavers, primarily controlled by...
