Humpback whales (Megaptera novaeangliae) in the South Pacific breeding grounds : an allocation from feeding areas and an abundance estimate of whales specific to French Polynesia waters

Creator:: Gibb, Giselle Renee
Abstract:: South Pacific humpback whales were devastated by commercial whaling in their Antarctic feeding areas during the 20th century. Understanding migratory connections and current abundance of these isolated breeding stocks is crucial for the allocation of historical Antarctic catches in population dynamic models used to assess current recovery. However, only a...

Virulence characteristics of infectious pancreatic necrosis virus (IPNV) in brook trout, Salvelinus fontinalis, fry

Creator:: Maret, Joseph J.
Abstract:: Infectious pancreatic necrosis (IPN) is an acute, contagious disease of trout fry and fingerlings caused by viruses of the family birnaviridae. IPN disease usually results in mortality that is inversely proportional to the age of the fish. While many studies have been carried out to increase our understanding of IPN,...

Genomics of migration : from marine distributions of salmonids to mechanisms of olfactory and magnetic cue perception for natal homing

Creator:: Bellinger, M. Renee
Abstract:: Substantial scientific investment has been directed towards understanding factors that influence distribution patterns and animals' remarkable ability for precise orientation and navigation, yet fundamental gaps in our knowledge remain. In my dissertation, I applied emerging genetic technologies to conduct a top-down and bottom-up investigation of animal movement and cue perception....

Worldwide phylogeography and local population structure of the rough-toothed dolphin (Steno bredanensis)

Creator:: Albertson, G. Renee
Abstract:: Several dolphin species have global distributions. The extent of their radiation and limits to gene flow are presumably a product of oceanographic features both recent and historical, behavioral specializations and social organization. Rough-toothed dolphins (Steno bredanensis) are globally distributed in tropical and subtropical waters and are generally found in depths...

Is the laboratory growth of Pacific oyster spat, Crassostrea gigas, exposed to varying salinities, predictive of their growth in the estuary?

Creator:: Brooks, Christopher
Abstract:: Results of this study suggest that laboratory growth of full-sib families of five month old Pacific oyster spat can be predictive of growth to market size at different grow-out sites. Seven to ten millimeter spat were selected from each of fifteen full-sib families and commercially available polyploids. Each family was...

Distribution and habitat use of bull trout following the removal of nonnative brook trout

Creator:: Renner, Dirk
Abstract:: Invasion by nonnative brook trout (Salvelinus fontinalis) often results in replacement of bull trout (Salvelinus confluentus) in western North America, but the causal mechanisms are not well understood. Removal of brook trout from 1992 to 2000 from Sun Creek in southern Oregon, provided an opportunity to investigate the changes in...

Feeding behavior and diet of native bull trout Salvelinus confluentus and introduced brook trout S. fontinalis in two Eastern Oregon streams

Creator:: Gunckel, Stephanie L.
Abstract:: One of the greatest threats to native bull trout Salvelinus confluentus populations is the presence of non-native brook trout S. fontinalis. This study, conducted in two second-order Eastern Oregon streams, investigates the effect of brook trout on the feeding behavior arid diet of bull trout. Feeding behavior, microhabitat use, and...

Movements of spawning sockeye salmon in Hidden Creek, Brooks Lake, Alaska

Creator:: Tsunoda, Setsuwo
Abstract:: The movements of a population of adult sockeye salmon (Oncorhynchus nerka) were followed in a small tributary of Brooks Lake, Alaska until spawning was nearly complete in 1963. The objectives of the study were to describe the movements of sockeye salmon on the spawning ground of an entire small stream,...

Responses of a threatened cutthroat trout to an introduced, invading salmonid : ecological implications for growth, stress, and behavior

Creator:: Osborne-Gowey, Jeremiah D.
Abstract:: Recent studies suggest that competition from brook trout (Salvelinus fontinalis; EBT) may have negative effects (e.g. displacement) on Lahontan cutthroat trout (Oncorhynchus clarki henshawi; LCT). Results from these studies have failed to elucidate the responsible mechanisms and have not examined if changing environmental conditions result in competitive/subordinate role reversals. The...

White-breasted nuthatch density and nesting ecology in oak woodlands of the Willamette Valley, Oregon

Creator:: Viste-Sparkman, Karen
Abstract:: Habitat loss causes a reduction in available resources for wildlife, alters the configuration of remaining habitat, and may isolate wildlife populations. White-breasted nuthatches (Sitta carolinensis) are experiencing long-term population declines in the Willamette Valley of Oregon, where they are historically associated with oak woodlands. As secondary cavity-nesters, white-breasted nuthatches may...
