Voluntary environmental programs at an alpine ski area: influence of recreationists' knowledge, motivations, attachment, value orientations, and specialization

Creator:: Little, Christopher M.
Abstract:: Voluntary environmental programs (VEPs) have been created to encourage companies to engage in behaviors that mitigate environmental impacts (e.g., recycling, emissions reduction). Many ski areas participate in the Sustainable Slopes Program, an initiative that promotes VEPs in the ski area industry. Past research has addressed the performance of VEPs in...

Vertebrates, arthropods, and invasive plants : an investigation of the top-down and bottom-up interactions of multiple herbivore guilds in a grassland system

Creator:: Farrell, Kelly Anne
Abstract:: Humans are increasing the scale and frequency of many natural disturbances, as well as adding novel disturbances to ecosystems. This thesis uses the arthropod community as a metric to examine the multi-trophic responses to disturbances in California grasslands. Chapter 2 explores how the long-term exclusion of native vertebrate herbivores has...

Vegetation and Small Mammal Responses to Western Juniper (Juniperus occidentalis) Control in Eastern Oregon

Creator:: Morozumi, Corinne N.
Abstract:: Shrub-steppe ecosystems of western North America provide habitat for many wildlife species, are important components of public and private rangelands, and offer recreational opportunities for millions of people. They are some of the most vulnerable ecosystems in the United States and have been altered by human activities such as livestock...

Utilization of the Non-Native Seagrass, Zostera japonica, by Crab and Fish in Pacific Northwest Estuaries

Creator:: Sund, Daniel M.
Abstract:: The introduction of non-native species often results in fundamental changes in the structure and function of disturbed environments. In the Pacific Northwest (PNW), the introduced seagrass Zostera japonica is rapidly expanding in distribution, impacting stakeholders and public use of the intertidal. Z. japonica’s expansion has prompted a number of different...

Use of Targeted and Non-Targeted Analysis to Study Complex PAH Environmental Mixtures

Creator:: Chibwe, Leah
Abstract:: Polycyclic aromatic hydrocarbons (PAHs) are ubiquitous contaminants formed from the incomplete combustion of organic material. These contaminants are of concern because of their widespread presence in the environment and toxic properties. In addition, PAHs encompass a class of diverse compounds with varying physicochemical properties and exist in the environment as...

Use of GIS software to map contaminant distributions and determine integrated dose for purposes of assessing impact to biota

Creator:: Myers, Margaret C.
Abstract:: The objective of this research was to estimate the radiological impact on various non-human biotas by the Fukushima Daiichi Nuclear power plant radiation release resulting from Japan's tsunami in March 2011 consistent with the recent recommendations of the International Commission on Radiological Protection. Soil concentration data given by Japan's Ministry...

Urban and rural-residential land uses : their role in watershed health and the rehabilitation of Oregon's wild salmonids

Creator:: Independent Multidisciplinary Science Team
Abstract:: Urban areas currently cover a small fraction of Oregon’s landscape but will expand to accommodate an increasingly large proportion of the state’s growing population and economic activity. Residential developments on rural lands now cover more than twice the area occupied by Oregon’s urban developments and are growing rapidly. Oregon urban...

Tsunami and hurricane wave loads on bridge superstructures

Creator:: Azadbakht, Mohsen
Abstract:: This dissertation examines tsunami and hurricane wave loads on bridge superstructures. Tsunamis have caused significant damage to coastal communities in recent years. For example, the 2011 Great East Japan Earthquake and resulting Tohoku Tsunami destroyed infrastructure along the east coast of Japan including bridge superstructures. Recent hurricanes have also caused...
