Carp, Climate, and Water Quality: Applying Systems Modeling to Ecosystem Recovery in Malheur Lake

Creator:: Pearson, James B.
Abstract:: Shallow lakes exist in either a clear or turbid state, with the clear state characterized by an abundance of aquatic macrophytes, diverse aquatic biota, low water column nutrients and phytoplankton biomass, whereas the turbid state is characterized by the opposite. These two distinct states are maintained by reinforcing (positive) feedback...

Consistency of associate degree definitions and graduation requirements in the California community colleges : perceptions of community college curricular leaders

Creator:: Borg, Carolyn Sue
Abstract:: The purpose of this study was to produce data and information that inform California Community College decision-makers of: (a) extent of variance in California's associate degree definitions and graduation requirements, and (b) perceptions of curricular leaders regarding the variances. Associate degree definitions and graduation requirements were compiled and analyzed from...

Factors Influencing Growth and Bioenergetics of Fish in Forested Headwater Streams Downstream of Forest Harvest

Creator:: Jensen, Leslie R.
Abstract:: In this study, we used a combination of conventional statistical analyses and mechanistic bioenergetics models to understand the potential effects of environmental variability on growth of stream-living fishes in four headwater streams subject to upstream forest harvest. We focused on two common fish consumers in headwater streams in the Pacific...

Bioenergetic evaluation of diel vertical migration by bull trout

Creator:: Eckmann, Madeleine
Abstract:: I evaluated hypotheses related to growth as a driver of depth use and diel vertical migration by bull trout (Salvelinus confluentus) in a thermally stratified reservoir. I applied a bioenergetic model to evaluate growth of bull trout in relation to potential patterns of diel depth use by bull trout in...

Breeding site selection by coho salmon (Oncorhynchus kisutch) in relation to large wood additions and factors that drive reproductive success

Creator:: Clark, Steven
Abstract:: The fitness of female Pacific salmon (Oncorhynchus spp.) with respect to breeding behavior can be partitioned into at least four components: survival to reproduction, competition for breeding sites, success of egg incubation, and suitability of the local environment near breeding sites for early rearing of juveniles. Accordingly, breeding sites should...

Where the Stream Meets the Road : Prioritizing Culvert Replacement for Fish Passage

Creator:: Reagan, Rachel E.
Abstract:: Streams across the world are highly fragmented due to the presence of in-stream barriers (e.g., dams and stream-road crossings), many of which restrict or block fish passage. Retrofitting or replacing these structures is a high priority for restoring habitat connectivity for native fishes and other aquatic organisms in the Pacific...

Transferability of models to predict selection of cover by coastal cutthroat trout in small streams in western Oregon, USA

Creator:: Andersen, Heidi V.
Abstract:: We assessed use and selection of cover by coastal cutthroat trout (Oncorhynchus clarkii clarkii) in six headwater streams in three watersheds in western Oregon, USA during the summer low flow period from 1 August and September 30, 2007. We tagged 1037 coastal cutthroat trout (>100 mm) with passive integrated transponder...

Evaluating the Ecological Trade-Offs of Riparian Thinning for Stream Ecosystems in Second-Growth Redwood Forests of Northern California

Creator:: Roon, David A.
Abstract:: Riparian forests provide a myriad of ecosystem functions for adjacent streams and rivers, and due to these linkages, changes in riparian forest conditions can have direct implications for stream ecosystems. Resource managers in the coast redwood forests (Sequoia sempervirens) of northern California (USA) are actively thinning second-growth stands to accelerate...

An investigation into the characteristics, perceptions, and expectations of high school students involved in a pilot statewide tech prep in agriculture program in Washington state

Creator:: Willis, James Franklin
Abstract:: The purpose of the investigation was to develop a profile of characteristics, perceptions and expectations of high school students involved in the Washington Tech Prep in Agriculture Statewide Articulation Program (TPAG). The investigation involved nine individual interviews, the responses of 165 students to a forced response survey instrument, and a...

Assessment of the causal linkages between forests and fish: implications for management and monitoring.

Creator:: Martens, Kyle D.
Abstract:: Understanding the causal links between riparian forests, streams, and salmonids is important to help understand the likely effects of forest management practices. Previous studies have identified three major causal pathways (Instream Cover, Light, and Hydrology) through which riparian forests influence streams, and ultimately stream fishes. To evaluate the potential importance...
