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...

Racial identification of chinook salmon (Oncorhynchus tshawytscha) and juvenile steelhead trout (Salmo gairdneri)

Creator:: Martin, James T.
Abstract:: Efforts to manage stocks of salmonids in Pacific Northwest stream systems are complicated by the occurrence of several runs of a species thought to represent races rearing sympatrically as juveniles. In order to collect the population statistics needed to properly manage these stocks, managers need a method of identifying juvenile...

Rare, endangered, and recently extirpated mammals in Oregon

Creator:: Olterman, James Howard
Abstract:: This paper lists, and gives individual accounts of, those Oregon mammals that at some time have been referred to as being of a status other than common. Although rare and endangered wildlife species were listed on a national level in the United States, the large areas of land included in...

The Influence of Scale in a Structured Decision Making Framework for Chinook Salmon Management

Creator:: McDonnell, Kevin N.
Abstract:: The goal of my dissertation was to explore how scale influences stream restoration prioritization strategies for an anadromous species and identify influential uncertainties that exist at different scales. My objectives were to (1) produce a comprehensive review of the Chinook salmon management challenges in California’s Central Valley and identify the...

Evaluating the Effects of a Parasitic Copepod (Salmincola californiensis) on the Performance of Juvenile Chinook Salmon (Oncorhynchus tshawytscha)

Creator:: Neal, William T.
Abstract:: Pacific salmon (Oncorhynchus spp.) rearing in lakes and reservoirs have been known to become heavily infected with an ectoparasitic copepod (Salmincola californiensis). Little is known about the factors that affect the parasite infection prevalence and intensity. However, previous research suggests that the parasite may negatively affect the fitness and survival...

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...

Linking Moral Obligations, Assumption-based Research, and Structured Decision Making to Inform Bull Trout Recovery

Creator:: Brignon, William R.
Abstract:: More than 1500 species of plants and animals in the United States are listed as threatened or endangered under the Endangered Species Act (ESA). The U.S. Departments of Interior and Commerce are required, under Section 4(f)(1) of the ESA, to develop recovery plans for ESA-listed species under the respective agency...

Carbon Dynamics in Response to Land Cover Change in Tropical Peatlands, Kalimantan, Indonesia

Creator:: Basuki, Imam
Abstract:: This study focuses in providing the knowledge on carbon (C) stocks, emission and ecosystem productivity related to land use/land cover change in tropical peatlands. The field research activities were conducted for about 17 months between August 2013 to December 2015, at Pematang Gadung peat dome (peat depth up to 10.5...

Distribution and movements of Chinook salmon, Oncorhynchus tshawytscha, returning to the Yukon River basin

Creator:: Eiler, John H.
Abstract:: Chinook salmon, Oncorhynchus tshawytscha, returning to the Yukon River basin and other large river systems in western Alaska have declined dramatically since the late 1990s. This continuing trend has raised concerns over the future status of the returns, and severely impacted commercial and subsistence fisheries within the drainage. Management is...
