Effects of habitat manipulations on California quail in western Oregon

Creator:: Oates, Russell M.
Abstract:: The effects of disking, food plantings, and wheat plantings on a population of California quail (Lophortyx californicus) were studied from fall 1976 to spring 1978 on the E.E. Wilson Wildlife Area, Oregon. Twelve 16.2-ha study sites were established: 3 study sites for each treatment and 3 control sites. Disked areas,...

The effects of harvesting Pacific hake (Merluccius productus) on the offshore community : the results of a multi-species model

Creator:: Gartz, Russell G.
Abstract:: The effects of harvesting Pacific hake (Merluccius productus) were examined with a multi-species numerical model composed of seven logistic growth equations coupled by a food web. The food web was composed of: California sea lions (Zalophus californianus), hake, sablefish (Anaplopoma fimbria), spiny dogfish (Squalus acanthias), a generic rockfish species (Sebastes...

Fish and invertebrate distribution at multiple scales in Thomas Creek, Oregon : a transition from conifer uplands to agricultural lowlands

Creator:: Langshaw, Russell B.
Abstract:: Longitudinal patterns of fish and benthic invertebrate distribution and habitat use were similar in Thomas Creek, Oregon but clarity of these patterns differed. I studied fish and aquatic invertebrates simultaneously, at multiple scales, and used multivariate statistical techniques to compare responses to the same environmental conditions. Both types of organisms...

Evaluating Fish Rescue as a Drought Adaptation Strategy for Imperiled Coho Salmon: A Life-Cycle Modeling Approach

Creator:: Beebe, Brittany A.
Abstract:: Projected intensification of drought as a result of climate change may reduce the capacity of streams to rear fish, exacerbating the challenge of recovering ESA-listed salmon populations. Without management intervention, some stocks will likely go extinct as stream drying and fragmentation reduce juvenile survival to unsustainable levels. To offset drought-related...

Modeling abiotic influences on disease dynamics for the complex life cycle of the myxozoan parasite Ceratomyxa shasta

Creator:: Ray, Robert Adam
Abstract:: Most parasites and their hosts live in a balance within their environment; however a disease outbreak can occur when either the parasite, host, or environment, are perturbed. Myxozoan parasites are associated with a wide variety of cultured and wild fish populations. Most myxozoans are relatively benign to their vertebrate host;...

Thirty-four Kilometers and Fifteen Years : Rapid Adaptation at a Novel Chromosomal Inversion in Recently Introduced Deschutes River Three-spined Stickleback

Creator:: Hemstrom, William
Abstract:: Rapid adaptation and evolution based on standing genetic variation and novel mutations is likely to be one of the primary ways that species survive the widespread anthropogenic environmental changes expected of the next century. Three-spined stickleback (Gasterosteus aculeatus) are known to be capable of extremely quick, dramatic adaptation in response...

Greater sage-grouse reproductive ecology : linkages among habitat resources, maternal nutrition, and chick survival

Creator:: Gregg, Michael A.
Abstract:: Greater sage-grouse (Centrocercus urophasianus) populations declined range wide during the past 50 years. Grouse populations were 2-3 times larger than the current population as recently as the early 1970's. In addition to habitat loss and fragmentation, declines were attributed habitat degradation that caused reduced productivity. Because chick survival remains the...

Function of Oregon Estuaries to Juvenile Fishes, with Focus on Juvenile Rockfishes (Sebastes spp.) in Yaquina Bay, Oregon

Creator:: Schwartzkopf, Brittany D.
Abstract:: The role that anthropogenic and natural habitats in estuaries play in long-term population trends for Oregon’s nearshore marine fishes is poorly understood, in part due to limited temporal sampling. One important nearshore marine group is northeastern Pacific rockfishes (Sebastes spp.), which are highly diverse, with around 96 documented species, and...
