Long-term variation in growth of Dover sole (Microstomous pacificus) and English sole (Parophrys vetulus), and its possible relationship with upwelling

Creator:: Kreuz, Keith Francis
Abstract:: Variation in growth rate of Dover sole (Microstomous pacificus) off Astoria and Brookings, and English sole (Parophrys vetulus) growth off Astoria and Coos Bay, Oregon was studied using the distance between annuli on scales and interoperculum bones indicating growth rate for Dover sole and English sole respectively. The age at...

Growth and development of temperate and tropical passerines of the New World : a life history perspective

Creator:: Austin-Bythell, Suzanne H.
Abstract:: I studied developmental rates in a suite of temperate and tropical passerine bird species from the New World to test the hypothesis that tropical passerines exhibit slower patterns of growth and development than temperate birds. I also investigated how the expression of several developmental rates varied with life history traits...

The fishery biology of the weathervane scallop [Pecten (Patinopecten) caurinus Gould, 1850] in Oregon coastal waters

Creator:: Nunez, Jose D.
Abstract:: Samples of weathervane scallops taken on Oregon Department of Fish and Wildlife cruises off Oregon waters during 1981-1982 were analyzed for a comparative growth study. No evidence of internal growth marks were found in the shell structure when analyzed by the acetate peel technique. Internal growth lines formed in the...

The effects of different otolith ageing techniques on estimates of growth and mortality for two species of rockfishes, Sebastes pinniger and Sebastes diploproa

Creator:: Wilson, Christopher D.
Abstract:: The use of some age determination methods may result in the incorrect age structure of fish populations. This in turn may lead to incorporation of inappropriate data into models used for stock management. Otoliths are commonly used for determining the age of fishes, and ages based on the whole otoliths...

Development syndromes in New World temperate and tropical songbirds

Creator:: Austin, Suzanne H., Robinson, W. Douglas, Robinson, Tara Rodden, and Ricklefs, Robert E.
Abstract:: We studied avian development in 49 species of temperate and 153 species of tropical New World passerine birds to determine how growth rates, and incubation and nestling periods, varied in relation to other life-history traits. We collected growth data and generated unbiased mass and tarsus growth rate estimates (mass n...

Metamorphosis, growth, and settlement of Pacific sanddab (Citharichthys sordidus) to a continental shelf nursery, inferred from otolith microstructure

Creator:: Donohoe, Christopher James
Abstract:: Processes of metamorphosis, settlement, and growth were examined in Pacific sanddab using field studies and otolith microstructure. This flatfish transforms at large sizes, has a gradual metamorphosis, and settles to a nursery on the middle continental shelf. Eye migration takes 3 months and "metamorphosis proper" which begins after completion of...

The use of molecular biological methods to assess the effects of endocrine disrupting chemicals and natural hormones on growth in the sheepshead minnow (Cyprinodon variegatus)

Creator:: Knoebl, Iris
Abstract:: The work presented in this dissertation examines possible modes of action for growth inhibition by anthropogenic endocrine disrupting chemicals (EDCs) as well as endogenous hormones associated with growth in fish. Using the sheepshead minnow (SHM) (Cyprinodon variegatus) as a model, I developed methods to examine perturbations in the endocrine axis...

Improving Pacific oyster (Crassostrea gigas) production through selective breeding

Creator:: Evans, Sanford, 1968-
Abstract:: Shellfish growers have expressed interest in developing high-yielding oyster strains through selective breeding. This dissertation has three objectives to help determine the effects of genetic and environmental variation on production traits (body weight, survival, and yield) of Pacific oysters grown in the Pacific Northwest. Objective 1: Determine if relative family...
