Top-down Influences of bald eagles on common murre populations in Oregon

Creator:: Horton, Cheryl A.
Abstract:: Populations of organisms are influenced by both top-down (predator driven) and bottom-up (environment or resource driven) effects. Seabird research has largely focused on bottom-up factors influencing reproduction, with little emphasis on top-down. Our goal was to better understand top-down impacts on colonial nesting seabirds over a range of spatio-temporal scales....

Food habits and species composition of neritic reef fishes off Depoe Bay, Oregon

Creator:: Steiner, Richard George
Abstract:: The distribution and trophic ecology of neritic reef fishes was studied to provide biological information useful in conserving these stocks. Houk and line fishing was conducted from July 1976 to July 1977 on neritic reefs within 5 km of the Oregon coast adjacent to Depoe Bay. Sampling was designed to...

Life history, population dynamics, and management of signal crayfish in Lake Billy Chinook, Oregon

Creator:: Lewis, Scott D.
Abstract:: Signal crayfish Pacifastacus leniusculus were studied in Lake Billy Chinook, Oregon, during 1994 and 1995. Because little was known about the crayfish population, this study was conducted to obtain reliable estimates of life history and population parameters, document historic commercial harvests, and make management recommendations. Crayfish were captured with baited...

The physiology ecology and run diversity of adult Pacific lamprey, Entosphenus tridentatus, during the freshwater spawning migration

Creator:: Clemens, Benjamin J.
Abstract:: Pacific lamprey, Entosphenus tridentatus, have shown recent and rapid declines in abundance. These anadromous fish return to streams where they mature, spawn and die. It has been inferred that Pacific lamprey enter freshwater and reside for ~ 1 year before spawning. This long exposure to the freshwater environment may affect...

Tempo and Mode of Diversification in the Neotropical Fish Superfamily Anostomoidea (Ostariophysi: Characiformes)

Creator:: Frable, Benjamin W.
Abstract:: Neotropical characiform fishes form one of the most diverse freshwater ichthyofauna in the world. Knowledge of evolutionary processes that generated and maintain the immense characiform lineage and morphological diversity is still poorly understood. When did characiform lineages diversify? How have major geological and environmental changes affected diversification? Why are some...

Movement of tagged lingcod and rockfishes off Depoe Bay, Oregon

Creator:: DeMott, Glenn E.
Abstract:: A tagging study was conducted from June 1978 through January 1982 to provide information on the movements of adult neritic reef fishes off the central Oregon coast. To evaluate the cause of low tag returns of previous tagging studies of reef fish in this area, tag retention, post-tagging mortality, and...

Fertilization of salmonid eggs with cryopreserved sperm

Creator:: Ott, Alvin G.
Abstract:: Numerous fishery researchers have attempted to preserve viable fish sperm, but only three investigations were successful in the fertilization of fresh eggs with frozen and thawed sperm: Blaxter (1953); Hoyle and Idler (1968); and Graybill and Horton (1969). Significant advances reported in this thesis were: the development of suitable life...

Biology of the Rex sole, Glyptocephalus zachirus Lockington, in waters off Oregon

Creator:: Hosie, Michael J.
Abstract:: Data are presented on the life history and population dynamics of rex sole (Glyptocephalus zachirus Lockington) collected from Oregon waters between September 1969 and October 1973. Length-weight relationships vary little between sexes or with time of year. Otolith annuli form primarily from January through May and were used for age...
