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...

The effects of pathogens, UV-B radiation, and introduced species on amphibians in the Pacific Northwest

Creator:: Kiesecker, Joseph Michael
Abstract:: I examined two amphibian communities to assess factors that may impact amphibian biodiversity. The results suggest that the potential factors which influence the maintenance of amphibian biodiversity are multi-faceted and thus, attempts to understand these factors must reflect these complexities. I investigated factors that influenced the susceptibility of western toad...

Systematic and reproductive studies of Mimulus (Scrophulariaceae) in the Pacific Northwest : implications for conservation biology

Creator:: Meinke, Robert James
Abstract:: The Mimulus washingtonensis complex is a group of morphologically similar species centered in the Pacific Northwest. All are rare, and most are under consideration for listing as endangered. Morphometric and pollination data were used in developing a revised taxonomy for the group. Five species and two varieties are recognized. Mimulus...

Structure and seismic hazards of the offshore Cascadia forearc and evolution of the Neogene forearc basin

Creator:: McNeill, Lisa C.
Abstract:: The Cascadia subduction zone has been characterized as a typical Chilean-type subduction zone based on qualitative comparisons of plate age and convergence rate, with simple forearc structure. However, the discovery of unusual structural styles of deformation, variations in the morphology of the forearc, and its absence of seismic activity suggest...

Root decomposition in three coniferous forests : effects of substrate quality, temperature, and moisture

Creator:: Chen, Hua
Abstract:: Controls of substrate quality, temperature, and moisture on woody root decomposition in the Pacific Northwest were explored using chronosequences, time series, laboratory incubations, and simulation modeling approaches at three sites: Cascade Head (CAH), H. J. Andrews (HJA), and Pringle Falls Experimental Forests (PRF). In the chronosequence study, a structural component-oriented...

Stream classification in the Pacific Northwest : methodologies, regional analyses, and applications

Creator:: Castro, Janine M.
Abstract:: Stream management and design recommendations related to the Salmon Habitat Recovery Program in the Pacific Northwest require area specific information concerning appropriate methods of stream classification, bankfull discharge recurrence intervals, and hydraulic geometry relationships. New region specific information, based on field measurements, is presented here. The Rosgen Classification of Natural...

Mycorrhizal and other root endophytic fungi of lupines in the Pacific Northwest

Creator:: O'Dell, Thomas E.
Abstract:: We investigated the root endophytic fungi of lupine using four approaches: (1) occurrence of fungal colonization in field-collected roots; (2) growth response of L. latifolius to inoculation with two types of fungi; (3) structure of root colonizations of Pinus and Lupinus by Phialocephala fortinii, a septate endophytic fungus of lupine;...

Population dynamics of three early seral herb species in Pacific Northwest forests

Creator:: Hanson, D. Eric
Abstract:: I investigated the population dynamics of fireweed (Epilobium angustfolium), foxglove (Digitalis purpurea) , and woodland groundsel (Senecio sylvaticus) to understand their colonization, persistence, and extirpation in Pacific Northwest Douglas-fir forests. Factors affecting the species' frequency and abundance in forest communities were evaluated. Their population dynamics were modeled and field experiments...

Implementation of regional plans in the Pacific Northwest : an analysis of the Northwest Power Planning Council's water budget and model conservation standards 1984-1993

Creator:: Mullens, Jo Beth, 1964-
Abstract:: An innovative regional planning institution, the Northwest Power Planning Council, was created to plan for two conflicting water-related resources, fish and wildlife and electrical power. The Council is responsible for regional planning but implementation of those plans is largely the responsibility of four federal agencies and four state governments. As...
