Disturbance and roosting ecology of California brown pelicans (Pelecanus occidentalis californicus) on East Sand Island in the Columbia River Estuary

Creator:: Wright, Sadie K.
Abstract:: The California brown pelican (Pelecanus occidentalis californicus) is listed as an endangered species under the U.S. Endangered Species Act. The Recovery Plan for this subspecies outlines the need to "Assure long-term protection of adequate food supplies and essential. . .roosting. . . habitat throughout the range." I investigated the effects...

Steller sea lions (Eumetopias jubatus) of Oregon and Northern California: seasonal haulout abundance patterns, movements of marked juveniles, and effects of hot-iron branding on apparent survival of pups at Rogue Reef

Creator:: Scordino, Jonathan
Abstract:: The Steller Sea Lion Research Initiative was passed in 2001 to provide funding to help scientists determine causes and solutions for the population crash of Steller sea lions (Eumetopias jubatus). In response to need to understand population dynamics of Steller sea lions, NOAA Fisheries has spearheaded a large-scale, range-wide research...

Rearing of channel catfish, Ictalurus punctatus (Rafinesque), and brown bullheads, I. nebulosus (Lesuer), in floating cages in a pond near Corvallis, Oregon

Creator:: Nielsen, James Robert
Abstract:: A study designed to evaluate the use of floating cages for rearing fingerling and subadult channel catfish (Ictalurus punctatus) and fingerling brown bullheads (I. nebulosus) on a commercial basis in Oregon's Willamette Valley was conducted at a pond seven miles north of Corvallis, Oregon, from May 23 to October 17,...

The effects of water withdrawals on the emergence timing, adult body mass, and total emerging biomass of aquatic insects from two northeast Oregon rivers

Creator:: Brown, Phil D.
Abstract:: Small low-head diversion dams are capable of removing much of the flow of a river, often resulting in increased water temperatures and habitat loss. Warmer temperatures have been shown to accelerate aquatic invertebrate growth and development, and discharge reductions can reduce instream habitat, suggesting that water withdrawals may alter both...

Relationship between plant and butterfly community composition on upland prairies of the Willamette Valley, Oregon

Creator:: York, Melissa M.
Abstract:: Small remnants of 'natural' habitats exist today throughout much of the world. Upland prairies in the Willamette Valley, Oregon have been nearly eliminated by conversion to agriculture and other uses. As a result, very few prairies remain and at least four butterfly species that require this habitat appear to be...

Long-term Colonization Of A Subarctic Artificial Reef System In Whittier, Alaska

Creator:: Levy, Charlotte S. and Brown, Eloise J.
Abstract:: Over half of the U.S. coastline is found in Alaska, and the majority of the state’s economic activity occurs along the coast. Increased coastal development poses a potential threat to nearshore habitats in Alaska. The installation of artificial reef (AR) systems can mitigate habitat loss; however, few AR systems have...

Dataset used for “The early life stages of California yellowtail (Seriola dorsalis) and white seabass (Atractoscion nobilis) respond to food particle taste more than smell.”

Creator:: Hawkyard, Matt, Langdon, Chris, Stuart, Kevin, and Drawbridge, Mark
Abstract:: This dataset was produced as a result of experiments conducted with simple and alginate complex particles that were used to evaluate feeding in California yellowtail and white seabass post larvae. Retention data was collected from a series of retention trials whereby particles were suspended in seawater for various lengths of...

Humpback Whale (Megaptera novaeangliae) Calling Behavior In Southeast Alaska : A Study In Acoustic Ecology And Noise

Creator:: Fournet, Michelle E. H.
Abstract:: Humpback whales (Megaptera novaeangliae) are a widely distributed baleen whale species, well known for their diverse acoustic behavior. On high-latitude foraging grounds, humpback whales produce a suite of non-song vocalizations (“calls”) in concert with foraging and social behavior. In this dissertation I investigated the role of calls in the acoustic...

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...

Extensive Resource Subsidies by Salmon-Supported Bears to Granivores

Creator:: Shakeri, Yasaman N.
Abstract:: In salmon-rich, northern coastal environments brown bears can occur at high densities and exert wide-ranging effects on ecosystem processes. Bear consumption of seasonally available fruit may provide important seed dispersal services to plants, and by extension, influence the ecology of seed consumers such as small mammals. In this study, we...
