Forest biomass estimation with hemispherical photography for multiple forest types and various atmospheric conditions

Creator:: Clark, Joshua Andrew
Abstract:: The importance of accurately identifying inventories of domestic energy, including forest biomass, has increasingly become a priority of the US government and its citizens as the cost of fossil fuels has risen. It is useful to identify which of these resources can be processed and transported at the lowest cost...

The mycorrhizal associations of western hemlock

Creator:: Kropp, Bradley Ray
Abstract:: Two objectives of this research were to identify fungi which are mycorrhizal with western hemlock and to examine the ecology of hemlock mycorrhizal fungi indigenous to outplanting sites. Another objective was to evaluate the effectiveness of mycorrhizal inoculation in improving the performance of outplanted hemlock seedlings. A list of over...

An investigative study in the systematic application of effectiveness indicators for institutional improvement in northwest community colleges

Creator:: Sorensen, James E.
Abstract:: In 1990, the Northwest Association of Schools and Colleges moved to an accreditation model based on outcomes, their assessment and deliberative attempts at institutional change and improvement. No study existed in northwest community colleges which identified the systematic application of effectiveness indicators for institutional change and improvement. This study was...

Teacher argumentation in the secondary science classroom : images of two modes of scientific inquiry

Creator:: Gray, Ron E.
Abstract:: The purpose of this exploratory study was to examine scientific arguments constructed by secondary science teachers during instruction. The analysis focused on how arguments constructed by teachers differed based on the mode of inquiry underlying the topic. Specifically, how did the structure and content of arguments differ between experimentally and...

Integration of Scientific and Local Knowledge in Data-Poor Fisheries Assessments

Creator:: Jara Baquero, Andrea C.
Abstract:: Small-scale fisheries (SSF) around the world face many challenges. They are a highly dynamic, important sector for coastal communities in developing nations, playing a critical role in poverty alleviation and food security. SSFs generally have few resources to ensure their long-term sustainability. They are often fished and managed locally and...

Developing NGSS Scientific Practices Through Inquiry in an Outdoor Learning Environment

Creator:: Halsey Randall, Micki Marie
Abstract:: The National Research Council has aggregated research evidence on the pedagogy of science teaching and learning (NRC, 2012), culminating in the Next Generation Science Standards (NGSS). These standards support emphasis on eight scientific practices as an important component for teaching science as inquiry to K-12 students. This latest framework for...

Population genetics, systematics, and habitat associations of chanterelles in the Pacific Northwest

Creator:: Dunham, Susie M.
Abstract:: Balancing resource extraction with protection of Pacific Northwest forest ecosystems requires understanding the population biology of ectomycorrhizal fungi. Design of landscape-scale management and research strategies requires understanding genet size, habitat requirements, and dispersal capabilities. The purpose of this dissertation was to gain knowledge about the distribution of genetic variation, systematics,...

Are Bird Habitat Associations Consistent Across Space and Time?

Creator:: Rousseau, Josée S.
Abstract:: The concept of the fundamental niche is frequently used in ecology to define the set of environmental conditions needed by a species to survive and reproduce (Hutchinson 1957). In contrast, the realized niche constitutes the locations where a species actually occurred, which is a function of both the environmental (abiotic)...

Systematics and host associations of Ormyrus species (Hymenoptera: Chalcidoidea)

Creator:: Hanson, Paul E.
Abstract:: The genus Ormyrus has a worldwide distribution and comprises about sixty recognized species. The higher taxonomic relationships of the genus are uncertain, as evidenced by its placement in the families Ormyridae, Pteromalidae, or Torymidae. Here, the genus is described in detail and a preliminary catalog of the world species is...

Anthropogenic activities associated with the status of salmon stocks in Pacific Northwest watersheds

Creator:: Mrakovcich, Karina Lorenz
Abstract:: Stocks of salmon are declining in the Pacific Northwest. Based on region-wide studies that list and categorize the status of salmon stocks (Nehlsen et al., 1991; Huntington et al., 1994; and Nawa, 1995), I analyze the watersheds where stocks of salmon spawn for several anthropogenic variables, most of which are...
