Age-specific and lifetime reproductive success of known age Northern Spotted Owls on four study areas in Oregon and Washington

Creator:: Loschl, Peter J.
Abstract:: Northern Spotted Owls (Strix occidentalis caurina) are a long-lived forest owl and range-wide declines in their numbers have resulted in the species being listed as threatened under the endangered species act. While many studies have been focused on population trends and reproductive performance of Spotted Owls from different age-classes, none...

Linkages among land use, riparian zones, and uptake and transformation of nitrate in stream ecosystems

Creator:: Sobota, Daniel J.
Abstract:: Land use alters the physical and biological structure of stream ecosystems and potentially alters their capacity to process nitrogen (N), an essential nutrient that has nearly doubled in abundance on the biosphere during the past century from human activities. In this dissertation, I quantified uptake and transformation of nitrate (NO₃⁻)...

Trophic dynamics of marine nekton and zooplankton in the Northern California Current ecosystem

Creator:: Miller, Todd William
Abstract:: The Northern California Current (NCC) ecosystem exhibits extreme seasonal, interannual and interdecadal shifts in the abiotic environment and shifts in primary and higher production. This variability is also apparent in the spatial structure of the ecosystem with nearshore-shelf waters (<150 m isobath) being highly productive and having a different community...

The effect of landscape topography and in-stream habitat on the distribution, growth, and survival of Lahontan cutthroat trout (Oncorhynchus clarki henshawi) in a high desert watershed

Creator:: Boxall, George D.
Abstract:: Lahontan cutthroat trout (LCT) (Oncorhynchus clarki henshawi) are currently limited in their distribution to a patchwork of small isolated populations, the result of habitat degradation and natural variation in landscape and in-stream conditions. The objectives of this study were to determine how landscape level topographic features influence LCT distribution patterns....

Dissolved oxygen requirements of freshwater fishes

Creator:: Doudoroff, Peter and Shumway, Dean L.
Abstract:: This critical review of literature on dissolved oxygen requirements of freshwater fishes is one of a series of papers on water quality criteria, the formulation of which is a prerequisite to the control of water pollution. It was prepared for FAO by the State of Oregon (acting by and through...

Seasonal dynamics of a riparian food web in the Oregon Coast Range mountains

Creator:: Robillard, Amanda Lynn
Abstract:: Riparian areas are eco-tones where aquatically- and terrestrially-derived insect biomass is exchanged between habitats, presenting consumers with new sources of energy, and resulting in a reciprocal subsidy. The relative contribution of energy exchange and the resulting impacts on vertebrate riparian consumers, such as fish or birds, remains poorly understood. We...

Functional relationships among vegetation, nocturnal insects, and bats in riparian areas of the Oregon Coast Range

Creator:: Ober, Holly K.
Abstract:: Vegetation provides food for many insects, and many insects serve as food for bats. We investigated the linkages among these three trophic levels in riparian areas throughout the Oregon Coast Range by examining the influence of vegetation cover, composition, and structure on the activity of nocturnal insects and bats, the...

Regions to streams : spatial and temporal variation in stream occupancy patterns of coho salmon (Oncorhynchus kisutch) on the Oregon coast

Creator:: Flitcroft, Rebecca L.
Abstract:: Aquatic ecological investigation is expanding to encompass considerations of multiple scales across large landscapes. Much of the analysis included in this work focuses specifically on coho salmon (Oncorhynchus kisutch) in multiple subbasins on the Oregon coast. Coho salmon were chosen for an investigation of spatial scales, network connections, and life...

Validating songbird habitat relationship models

Creator:: Wilson, Dorothy G.
Abstract:: Models are commonly used to assess and predict wildlife response to management practices. Model validation is essential if managers are to use them with confidence. Fifteen forest bird-habitat relationship models were developed by biologists using data collected from private forestland in southwest Washington. These models predict species' probability of occurring...

Population demography, resource use, and movement in cooperatively breeding Micronesian Kingfishers

Creator:: Kesler, Dylan C.
Abstract:: Island systems and species are susceptible to extinction because of their small population size and an ecological naiveté from an evolutionary past lacking strong competition and predation. For example, only one-fifth of the world’s bird species occur on islands, yet more than 90% of the avian extinctions witnessed during historic...
