Habitat Selection by Greater Sage-Grouse During Winter in Southeastern Oregon

Creator:: Hagen, Christian A., Willis, Mitchell J., Glenn, Elizabeth M., and Anthony, Robert G.
Abstract:: The distribution and geographic range of Greater Sage-Grouse (Centrocercus urophasianus) have been reduced by 56% since European settlement. Although loss and fragmentation of sagebrush (Artemisia spp.) habitats have been cited as the primary causes for the decline of the species, degradation of existing habitat also has been considered an important...

Accounting for Transient Dynamics Improves use of Marine Protected Areas as a Reference Point for Fisheries Management

Creator:: Quennessen, Victoria I.
Abstract:: Fisheries management that is based on quantitative assessment has commonly relied on estimating the unfished biomass of a fished stock to compare current and historical population size. Developing predictive models for this requires many years of catch and abundance data. Smaller, new, or mainly recreational fisheries may not have the...

Patterns of temporal and spatial habitat use by sympatric speckled dace (Rhinichthys osculus) and longnose dace (R. cataractae) in an Oregon Cascades stream

Creator:: Dodge, Karen L.
Abstract:: Microhabitat use by adult speckled dace (Rhinichthys osculus), adult longnose dace (R. cataractae), and juvenile dace (R. spp.) was investigated during the summer of 1992 in an Oregon Cascades stream. Selected areas were snorkeled day and night in order to evaluate differential use of habitat resources both temporally and spatially....

Juvenile Coho Salmon (Oncorhynchus kisutch) Diet in Brackish and Freshwater Habitats in the Stream-estuary Ecotones of Coos Bay, Oregon

Creator:: Mackereth, Kailan F.
Abstract:: Loss of lowland estuarine and freshwater off-channel habitats along the Pacific Northwest coast has contributed to the decline of salmonid populations. These habitats serve as nursery grounds for juvenile salmonids providing them with food, winter shelter, and a transition zone between freshwater and saltwater. Lowland areas have undergone anthropogenic alterations...

Influence of 2,4-dichlorophenol on the flavor of fish

Creator:: Palensky, John R.
Abstract:: A laboratory investigation was performed to determine the influence of 2,4-dichlorophenol on the flavor of fish. The study was conducted at the Oak Creek Fisheries Laboratory of the Department of Fisheries and Wildlife, Oregon State University. The three experimental apparatus used in this study were designed to deliver 250 ml/min...

Time and energy budgets of a population of dippers (Cinclus mexicanus) during winter in the Cascade Range of Oregon

Creator:: Parsons, David R.
Abstract:: A time and energy budget was constructed for a population of dippers (Cinclus Mexicanus) in the Cascade Range of Oregon during winter. A total of 12,202 point observations of activity were made from nine observation blinds from 19 November 1973 to 10 February 1974. Approximately 50 percent of all observations...

Reproductive rates of copepods in experimental ponds in Oregon

Creator:: Lindland, Ronald L.
Abstract:: Rates of birth, death and population change were calculated for Cyclops sp. and Diaptornus forbesi in Soap Creek Ponds V-VIII near Corvallis, Oregon during the interval April, 1968 to April, 1969. An egg ratio method was used in calculating these rates. Duration of development of the eggs of both species...
