Satellite Monitoring of Earth’s Surface Temperature : Effects of Land Cover, Disturbance, and a Changing Climate

Creator:: Mildrexler, David J.
Abstract:: The Earth’s surface is experiencing unprecedented change. Humanity’s growing population, expanding land-use footprint, and increasing global emissions of atmospheric greenhouse gases affect a vast number of species on Earth and the functioning of virtually all ecosystems. Given the vital interactions and feedbacks between the Earth’s land surface and climate, measurements...

Habitat Use of Female Columbian Black-tailed Deer in Western Oregon

Creator:: Schrautemeier, Timothy J.
Abstract:: Columbian black-tailed deer (Odocoileus hemionus columbianus) are important economically, ecologically, and culturally as an indigenous species in western Oregon. Oregon Department of Fish and Wildlife (ODFW) observed declines in black-tailed deer populations since the late 1980’s and attributes these declines to reduction in quality and availability of habitat, following the...

Assessment of the vulnerability of Oregon and Washington's natural areas to climate change

Creator:: Margaret, Massie H.
Abstract:: There are currently more than 580 natural areas in Oregon and Washington managed by 20 federal, state, local, and private agencies and organizations. The natural areas network is unparalleled in its representation of diverse ecosystems found in the region and may be an excellent collection of sites for monitoring long-term...

A Multi-Spatial Scale Economic Analysis of the Impacts of Bear Damage to Douglas-fir on Private Timberlands in the Pacific Northwest

Creator:: Kline, Kristina N.
Abstract:: Black bears (Ursus americanus) in western Oregon and Washington peel bark from conifers in early spring to forage on the sugar-rich phloem and cambial tissues. This provides important energy at a time when similarly attractive forage is scarce. Bears often damage Douglas-fir (Pseudotsuga menziesii) trees in stands that are intensively...

Wading through Space and Time: Leveraging Geospatial Methods to Better Understand Recreation Behavior, Experience, and Impacts within a Densely Used Lake Destination

Creator:: Baker, Jenna T.
Abstract:: In the last decade, many U.S. parks and protected areas (PPA) experienced record breaking visitation levels. Managers of these PPAs face the challenging task of providing a range of quality and accessible outdoor experiences without compromising the integrity and health of surrounding ecosystems. Understanding how PPA visitors move and interact...

Quantification of Ecological Change Using Repeat Photography and Ground Based Lidar

Creator:: Batchelor, Jonathan L.
Abstract:: Remote sensing techniques have long been useful in quantifying changes in ecosystems and the field of remote sensing is constantly evolving to better assess and describe changes, both spatially and temporally. In this thesis I explored the novel use of two remote sensing methods to quantify ecosystems; repeat photograph to...

The development and decline dynamics of two ectomycorrhizal fungal mat soil microbial communities in response to a reciprocal soil transfer experiment in old-growth Douglas-fir forests

Creator:: Cappellazzi, Jed E.
Abstract:: Ectomycorrhizal fungi (EmF) form symbioses with trees. These symbioses profoundly influence forest ecology. Certain EmF form specialized profusions of hyphae, known as ectomycorrhizal fungal mats (mats) which are visible to the naked eye, alter forest soil biogeochemistry, substantially contribute to soil microbial biomass/respiration and support unique microbial communities. Piloderma and...

Potential effects of the invasive grass Ventenata dubia on elk habitat selection within the Starkey Experimental Forest and Range

Creator:: Crum, Keren-happuch R.
Abstract:: The invasive annual grass ventenata (Ventenata dubia) has become an increasing problem within western rangelands. Forage quality of areas infested with ventenata is reduced as its high silica content makes it unpalatable to livestock and wildlife. In the following study, I examined whether significant presence of ventenata affects habitat use...

Assessing Post-fire Tree and Understory Vegetation Response to a Mixed-severity Fire Gradient in the Klamath Mts., Oregon, USA

Creator:: Terzioglu, Cihat
Abstract:: Severe wildfires are increasing in the western United States, impacting vegetation structure, and in turn, forest regeneration conditions. These wildfires are also raising a substantial amount of scientific and management concern regarding the resilience of forested ecosystems, or the ability of the ecosystem to return to a pre-fire condition. This...

Political Ideology and Environmental Concern as Predictors of Attitudes toward Forest Management Practices in the Pacific Northwest

Creator:: Arnold, Molly L.
Abstract:: Few studies examine whether public attitudes toward forest management practices differ between public and private forests, with virtually no recent studies examining these differences in the Pacific Northwest, despite the coexistence of millions of acres of both public and private forest lands. Knowing whether public attitudes differ between public and...

Contributions of Epicormic Branches and Delayed Adaptive Foliage in Coastal Douglas-fir under Variable Density Management Regimes

Creator:: Punches, John W.
Abstract:: The contribution of delayed adaptive reiteration to crown maintenance was explored across a wide range of adjacent open space conditions in early-mature (approximately 60 year old) Douglas-fir located on the eastern slope of Oregon’s Coast Range. The stands had experienced uniform thinning in 1964-65 and 1980-81 to release dominant and...

Drivers and Impacts of a Recent Annual Grass Invasion: Ventenata dubia and Fire in the Inland Northwest

Creator:: Tortorelli, Claire M.
Abstract:: Biological invasions threaten native biodiversity, alter ecosystem function, and are a major cause of economic losses across the planet. The most impactful invaders alter disturbance regimes and initiate state shifts to outside the historical range of variability of the ecosystem. Concern for ecological and economic losses has prompted a rapid...

The expression of functional traits during seedling establishment in two populations of Pinus ponderosa from contrasting climates

Creator:: Kerr, Kelly L.
Abstract:: Vegetation patterns and species distributions are strongly linked to soil moisture regimes, and populations within a species from contrasting climatic regimes could exhibit differences in the degree to which certain functional traits related to establishment are expressed. Tree seedling survival is crucial for forest regeneration, and thus may be a...

The Benefits of Time: Characterizing Intra-and Inter-Annual Variability in Oregon Wetland Ecosystems Using the Landsat Spectral-Temporal Domain

Creator:: Fickas, Kate C.

However, free and open access to Landsat imagery combined with advances in data storage and computing are revolutionizing how the Landsat temporal domain is used to...

Biodiversity Responses in Early Seral Forests of the Klamath-Siskiyou: Comparisons with Birds, Bees, and Ground Beetles among Post-fire, Salvage Logging, and Intensive Forest Management Environments

Creator:: Frank, Graham S.
Abstract:: Early seral forests regenerating from stand-replacing disturbances provide unique habitat for many species in productive, temperate forest landscapes and contribute to supporting biodiversity. Population declines in some species associated with early seral forests have prompted concerns about the conservation of these habitats, particularly the characteristic structural and compositional complexity associated...
