The Effects of Tank Structure and Egg Size on the Production of Wild Steelhead (Oncorhynchus mykiss) Surrogate Fish

Creator:: Self, Katharine E.
Abstract:: One of the biggest hurdles for a juvenile salmonid (Oncorhynchus mykiss) is migrating downstream from freshwater spawning grounds to the ocean. Juveniles from wild broodstock were reared from the South Santiam River for more than 1 year at the Oregon Hatchery Research Center (OHRC) in Alsea, OR. The fish were...

Distribution and mortality of the Pacific coast band-tailed pigeon

Creator:: Silovsky, Eugene Donald
Abstract:: A study of the Pacific coast Band-tailed pigeon (Columbia fasciata Say) was conducted from August 1966 to September 1968. Bands recovered from 14,787 pigeons banded in the Pacific Coast states, 1929-65, were used to determine distribution, migration, and mortality. Data on the age structure of populations were obtained from 3,596...

Crop-milk cycles in band-tailed pigeons and losses of squabs due to hunting pigeons in September

Creator:: Zeigler, Don L.
Abstract:: The production of crop-milk in band-tailed pigeons was investigated to estimate losses of squabs that occur from hunting pigeons during September.¹ Living birds held captive were examined with a cystos cope and pigeons killed by hunters were examined in the field to determine changes in gross appearance of crops and...

Assessment of mule deer fawn survival and birth site habitat attributes in south-central Oregon

Creator:: Speten, David
Abstract:: Mule deer (Odocoileus hemionus) populations in south-central Oregon are near their lowest levels since census efforts began in 1961. I investigated fawn survival, cause-specific mortality, and factors contributing to mortality from 2010 – 2012 to identify potential causes for the decline. I also explored pre-parturition and parturition site characteristics. I...

Historic Survival Rates and Cause-Specific Mortality for Columbian Black-Tailed Deer in Southwest Oregon

Creator:: Groot, Kevyn A.
Abstract:: In contrast with other Odocoileus species, Columbian black-tailed deer (Odocoileus hemionus columbianus) population dynamics are not well understood throughout the species’ range. Concerns over apparent long-term population declines have prompted efforts to fill basic knowledge gaps including estimates of vital rates (fecundity, recruitment and survival) and cause-specific mortality. The Oregon...

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....

Survival Rates and Cause-Specific Mortality of Mule Deer in South-Central Oregon

Creator:: Mulligan, Elizabeth M.
Abstract:: It is critical for wildlife managers to understand the population dynamics of a harvested species, particularly for ungulates, which are a valuable wildlife resource. Due to concerns that mule deer (Odocoileus hemionus) populations in Oregon were declining, more comprehensive data on population vital rates and the factors potentially affecting them...

Characterizing Microplastic Ingestion in Black Rockfish (Sebastes melanops) along the Oregon Coast

Creator:: Lasdin, Katherine S.
Abstract:: Microplastics (<5mm diameter) are present in a considerable number of marine and aquatic species. Understanding which species, the global spatial distribution, and what quantities of microplastics are present is extremely important for understanding the potential impacts they could have on recreationally important organisms and for the assessment of risk. We...
