Backcountry Recreation Modeling and the Extent of Human and Canine Fecal Markers in Subalpine Lakes of Mount Rainier National Park
Alpine lakes are some of the most fragile ecosystems in our national parks and forests and a focal point of backcountry visitation. As a result of climate change, access to these ecosystems is increasing due to annual ... -
Bark beetle and defoliator interactions across Pacific Northwestern forests
The dynamics of irruptive forest insects are changing rapidly in response to climate warming,altering many important ecosystem services and often overwhelming budgetary and logistical resources allocated to mitigate the ... -
Barred Owls and Northern Spotted Owls in the Eastern Cascade Range, Washington
(2013-07-23)Competitive interactions with barred owls (Strix varia) are an important factor contributing to the observed decline in the northern spotted owl (Strix occidentallis caurina) population in Washington. My goal was to develop ... -
Bee-crossed lovers and a forbidden Castilleja romance: Cross-breeding between C. hispida and endangered C. levisecta in prairie restoration sites
Castilleja levisecta (golden paintbrush) is one of Washington's characteristic endangered species, restricted to the Pacific Northwest's disappearing prairies. To establish new populations, C. levisecta was seeded into ... -
Between a Risk and a Hard Place: Scavenging Patterns and Habitat Selection of Carnivores in the Subarctic
Animals must balance the need to acquire sufficient resources against the risk of being consumed by a predator. This challenge is faced by many species which, though predatory, are also subject to predation. The ecological ... -
Bigleaf Maple Decline in Western Washington
Bigleaf maple (Acer macrophyllum Pursh) is a prominent component of the urban and suburban landscape in Western Washington, which lies at the heart of the native range of A. macrophyllum. Acer macrophyllum performs many ... -
Bigleaf Maple Sap Flow in Western Washington
Bigleaf maple (Acer macrophyllum) is common on well drained soils in mixed conifer forests and along river terraces in Western Washington. Protected riparian buffers often include bigleaf maple stands, and producing syrup ... -
Biochemical and thermochemical conversions of short rotation coppice poplar for carbohydrate and fuel production in lignocellulosic biorefineries
The economic success of a potential biorefinery is directly related to the use of economic feasible biomass. Due to high cost, it is unlikely that a wood-based biorefinery would use only whitewood material from conventional ... -
Bioconversion of heterogeneous lignocellulosic biomass for sugar production
In order to accomplish large scale utilization of lignocellulosic feedstocks to produce fuels and chemicals, a consistent, inexpensive and stable supply of biomass from a variety of sources will be required. These biomass ... -
Bioconversion of lignocellulosic hydrolysate to acetic acid using Moorella thermoacetica
A systematic study of bioconversion of lignocellulosic sugars to acetic acid by Moorella thermoacetica strain ATCC 39073 was conducted. Four different hydrolysates obtained after steam pretreatment of lignocellulosic biomass ... -
Biodegradation of Trace-level Organic Contaminants by Rhizosphere Microbial Communities
Wastewater treatment plants (WWTPs) remove simple organic compounds from wastewater but cannot fully degrade the thousands of trace-level organic contaminants (TOrCs) added to the waste stream each year. These TOrCs are ... -
Biodiversity, Carbon and Chocolate: Toward an Environmentally Friendly Cocoa Production System in Ghana
Global demand of cocoa for chocolate moved the native cocoa production frontier from ancient Maya and Aztec to other favorable tropical locations around the world. Cocoa growing arrived in West Africa sometime by the late ... -
Biology and conservation of the endangered Hawaiian Dark-rumped Petrel (Pterodroma phaeopygia sandwichensis)
(1983)The Hawaiian Dark-rumped Petrel or 'Ua'u is an endangered gadfly petrel that nests in the Hawaiian Islands and ranges throughout the central Pacific. The species was once common in Hawaii, with large colonies located on ... -
Bioremediation of Trichloroethylene: Analysis of the Plant Gene Response to TCE and Characterization of a Novel TCE-Degrading Endophyte
(2012-09-13)Trichloroethylene is a common environmental contaminant. High levels of TCE have the potential to cause liver damage and malfunctions in the central nervous system, and it is considered a likely human carcinogen. More than ... -
Bioretention Soil Media: Understanding the effects of compost and finding predictors for phosphorus leaching
This study is intended to 1) investigate the effect of compost rate and compost type on bioretention soil media (BSM) performance, and 2) explore possible predictors of phosphorus leaching from bioretention systems. Columns ... -
Birds in Suburbs: Altering Habitat, Species Assemblages, & Science Communication
Human modification of the environment rapidly alters ecological processes and the composition of plant and animal communities. Understanding the impacts of such anthropogenic disturbances are needed to predict future biotic ... -
Black-capped Vireos and White-eyed Vireos: How two birds adapt to challenges of living in Central Texas
Black-capped vireos (Vireo atricapilla) and white-eyed vireos (Vireo griseus) are closely related songbirds, which occupy the same landscape in Central Texas. While white-eyed vireos are common and widespread, black-capped ... -
Breeding Ecology of Golden Eagles in Western Washington
Raptors breeding in novel environments must find sufficient food resources to survive and reproduce. Available prey and landscapes surrounding territories can influence aspects of parental care and reproductive output. I ... -
Breeding territory settlement patterns and mate choice in a monochromatic tyrannid flycatcher
(2000)What factors influence a male's ability to acquire a high-quality territory and what cues do females use to select a mate in the monochromatic Pacific-slope flycatcher (Empidonax difficilis)? I addressed this question by ... -
Bridging the physiology and ecology of hemiparasitic plants
Metabolism based on photosynthesis is a defining feature of plants. However, some flowering plant lineages have adopted a heterotrophic lifestyle based on parasitism, either reducing or completely abandoning their ability ...
