The Response of Caspian Terns to Managed Reductions in Nesting Habitat in the Columbia Plateau Region, Washington State, USA

Creator:: Schniedermeyer, Ethan
Abstract:: Declines in populations of anadromous salmonids (Oncorhynchus spp.) in the Columbia River drainage basin have resulted in extensive programs to annually release large numbers of hatchery-raised juvenile salmonids in an effort to support salmonid restoration. The Pacific Flyway population of Caspian terns (Hydroprogne caspia) has grown from around 3,500 nesting...

Conserving avian diversity in agricultural systems : the role of isolated Oregon white oak legacy trees

Creator:: DeMars, Craig A.
Abstract:: Over one third of the earth’s land surface has been modified to some extent for agricultural purposes. The large global footprint of agriculture, combined with the knowledge that existing reserve networks are likely insufficient for long-term conservation of native biodiversity, has necessitated that agricultural systems contribute to conservation of native...

Characteristics of forests at spotted owl nest sites in the Pacific Northwest

Creator:: Hershey, Kit
Abstract:: This study describes the composition and structure of forests within the immediate vicinity of Northern spotted owl (Strix occidentalis caurina) nest sites in the Klamath, Coast, and Cascade provinces of western Oregon and the Olympic province, Washington. I compared forest stand data collected at 105 nest sites with data from...

Aspects of the foraging ecology of humpback whales (Megaptera novaeangliae) in Frederick Sound and Stephens Passage, Southeast Alaska

Creator:: Szabo, Andrew R.
Abstract:: The North Pacific humpback whale (Megaptera novaeangliae) population has been increasing at an average annual rate of ~6% since the early 1990s. In northern Southeast Alaska alone, there are now more whales than estimated for the entire North Pacific several decades ago. An understanding of how this growing population is...

Foraging ecology of caspian terns and double-crested cormorants in the Columbia River Estuary

Creator:: Lyons, Donald E.
Abstract:: A detailed understanding of the foraging ecology of species preying upon threatened or endangered prey may contribute to identifying and evaluating management options to reduce predation, when such management is deemed appropriate. In the Columbia River estuary, Caspian terns (Sterna caspia) and double-crested cormorants (Phalacrocorax auritus) have been identified as...

Breeding and foraging ecology of Caspian terns (Sterna caspia) in the mid-Columbia River : predation on juvenile salmonids and management implications

Creator:: Antolos, Michelle
Abstract:: I investigated Caspian terns (Sterna caspia) breeding at colonies on the Columbia Plateau (southeastern Washington and northeastern Oregon), with emphasis on the breeding and foraging ecology of Caspian terns nesting at colonies in the mid-Columbia River. I focused research at colonies where Caspian terns foraged on juvenile salmonids (Oncorhynchus spp.)...

Foraging ecology, colony attendance, and chick provisioning of Caspian terns (Sterna caspia) in the Columbia River Estuary

Creator:: Anderson, Scott K.
Abstract:: This study was designed to enhance understanding of factors influencing foraging distribution, diet composition, and overall reproductive success of Caspian terns (Sterna caspia) nesting on East Sand Island in the Columbia River estuary. This colony of nearly 10,000 breeding pairs is of concern to regional resource managers because Caspian terns...

Breeding and foraging ecology of Caspian terns nesting on artificial islands in the Upper Klamath Basin, California

Creator:: Patterson, Allison (Allison Glider)
Abstract:: Availability of suitable nesting habitat that is free of nest predators and provides access to adequate prey resources within commuting distance is a major factor limiting seabird populations. Caspian terns (Hydroprogne caspia) in western North America have shifted their breeding habitat from naturally occurring habitats in interior wetlands, lakes, and...

Susceptibility of juvenile salmonids to avian predation : Are Caspian terns and double-crested cormorants only taking the sick and injured?

Creator:: Hostetter, Nathan J.
Abstract:: The ability to non-destructively assess fish condition and subsequently track fish behavior and survival can be vital in understanding natural and anthropogenic stressors and sources of mortality, especially in populations of fish listed as threatened or endangered. I investigated the use of a quick, non-lethal, external examination technique to assess...

Bioenergetics-based predator-prey relationships between piscivorous birds and juvenile salmonids in the Columbia River estuary

Creator:: Lyons, Donald E.
Abstract:: This dissertation focuses on the predator-prey relationship between two species of avian predators, Caspian terns (Hydroprogne caspia) and double-crested cormorants (Phalacrocorax auritus), and one of their important prey types, juvenile salmonids (Oncorhynchus spp.), in the Columbia River estuary of Oregon and Washington states during the period 1998 – 2007. I...
