Transport of the copepod, Calanus finmarchicus, in the northwest Atlantic during diapause

Creator:: Kowalke, Gregory L.
Abstract:: The copepod Calanus finmarchicus is the most important and biomass dominant mesozooplankter in the temperate-boreal North Atlantic. C. finmarchicus has an overwintering phase, termed diapause, during which it descends to great depths (300-2000m) and is metabolically quiescent for up to ten months. Changes in the currents at depth due to...

Bioenergetics individual based model explorations of juvenile coho salmon growth during their first summer on the Oregon shelf

Creator:: Reser, Brendan Alexander
Abstract:: Salmon survival and eventual recruitment success have long been thought to be determined within the first summer following ocean migration. Juvenile growth during this period is largely influenced by ocean conditions such as temperature, prey availability, abundance, and quality. Shifts in these conditions due to climatic perturbations are particularly prevalent...

Development, performance evaluation and application of a physical model of the Kenyan-Tanzanian coastal region

Creator:: Mayorga Adame, Claudia Gabriela
Abstract:: A Regional Ocean Modeling System (ROMS) application for the coastal region of Kenya and Tanzania (0-10° S, 38.7-46.98° E) was developed with the aim of better resolving the circulation patterns in the coastal region that is poorly represented in global models. The model has a horizontal resolution of 4 km,...

Foraging ecology and reproductive energetics of the Kittlitz's murrelet (Brachyramphus brevirostris) in Southeast Alaska

Creator:: Hatch, Nick R.
Abstract:: The Kittlitz's murrelet (Brachyramphus brevirostris) is a species of conservation concern over the entirety of its known range, which spans coastal Alaska and northeastern Russia. Concerns about the status of the species have been raised due to evidence of population declines in key breeding areas, low reproductive output, and perceived...

Horizontal and vertical distribution of juvenile pollock (Theragra chalcogramma) in the southeastern Bering Sea

Creator:: McIntosh, Neal E.
Abstract:: Juvenile walleye pollock (Theragra chalcogramma) are one of the primary prey items for bird and mammal predators in the Bering Sea and support a large commercial fishery. An understanding of the environmental factors that determine the horizontal and vertical distribution of juvenile pollock is needed to estimate the effects that...

Prey consumption, survivorship and oviposition by adults of the bark beetle predator Thanasimus dubius Fabricius (Coleoptera:Cleridae)

Creator:: Turnbow, Robert Harold
Abstract:: Laboratory studies were conducted to evaluate the effects of prey availability on prey consumption, survivorship and oviposition of the southern pine beetle predator, Thanasimus dubius Fabricius. Although prey consumption rates were significantly affected by the sex, size and ovipositional status of the predator, it was found through correlation analyses that...

The biology and pathogenicity of a sheath nematode Hemicycliophora similis Thorne, 1955

Creator:: McKewan, Jeanette Anne
Abstract:: A study, using greenhouse and laboratory experiments, was made of Hemicycliophora similis from Bandon, Oregon to determine: identity and morphometrics, time and development of a life cycle, host plant preferences and optimum environmental conditions for reproduction and pathogenicity. Morphometric investigations revealed discrepancies between the measurements of this nematode species and...

Chemical features of the Columbia River plume off Oregon

Creator:: Cissell, Milton Charles
Abstract:: An intensive chemical investigation, that includes the determinations of salinity, oxygen, nutrients, pH, alkalinity, and total carbon dioxide of the Columbia River plume off the Oregon coast in July 1967 shows the following unique features: 1. Along the axis of the river plume both the salinity minimum and temperature maximum...
