Influence of channel constraint on primary production, preiphyton biomass, and macroinvertebrate biomass in streams of the Oregon Coast Range

Creator:: Zucker, Steven J.
Abstract:: Differences in primary production and periphyton and macroinvertebrate biomass between pairs of constrained (valley floor width of less than twice the active channel width) and unconstrained reaches were investigated in Elk River and four tributaries in southwest Oregon. In August 1991, macroinvertebrates were sampled from individual cobbles, and rocks were...

Seasonal movement patterns and habitat use of westslope cutthroat trout in two headwater tributary streams of the John Day River

Creator:: Starcevich, Steven J.
Abstract:: Radiotelemetry was used to study the seasonal movements and habitat use of adult westslope cutthroat trout Oncorhynchus clarki lewisi in Roberts Creek and Rail Creek, headwater tributaries of the John Day River, Oregon, from September 2000 to December 2001. The objectives were to (1) describe adult cutthroat trout life history...

Recruitment variability in black rockfish (Sebastes melanops): effects of maternal age on offspring quality

Creator:: Chapman, Colin G.
Abstract:: Black rockfish (Sebastes melanops) is an important marine recreational species throughout the Pacific Northwest. Recent catch data indicate a trend of age-truncation in the black rockfish population off the Oregon coast, with older females rapidly disappearing from the population. In populations with broad age distributions, older fish may contribute disproportionately...

Breeding site selection by coho salmon (Oncorhynchus kisutch) in relation to large wood additions and factors that drive reproductive success

Creator:: Clark, Steven
Abstract:: The fitness of female Pacific salmon (Oncorhynchus spp.) with respect to breeding behavior can be partitioned into at least four components: survival to reproduction, competition for breeding sites, success of egg incubation, and suitability of the local environment near breeding sites for early rearing of juveniles. Accordingly, breeding sites should...

Dispersal Behavior in African Buffalo (Syncerus caffer) : Tradeoffs Between Nutritional Resources and Disease Exposure

Creator:: Spaan, Robert Steven
Abstract:: Dispersal facilitates population health and maintains resilience in species via gene flow. Adult dispersal occurs in some species, is often facultative, and is poorly understood, but has important management implications, particularly with respect to disease spread. Although the role of adult dispersal in spreading disease has been documented, the potential...

Occurrence and relative abundance of small mammals associated with riparian and upland habitats along the Columbia River

Creator:: Hinschberger, Mark Steven
Abstract:: A small mammal inventory of occurrence and relative abundance was conducted in riparian and upland habitats in six segments along the lower Columbia River from the river mouth to McNary Dam (river mile 292) during 1974 and 1975 by removal trapping on standardized trap lines. Analysis of variance was used...

The heritability of resistance to gas bubble disease of Columbia River fall Chinook salmon, (Oncorhynchus tshawytscha)

Creator:: Cramer, Steven P.
Abstract:: A nested mating experiment in which 20 males were each mated to four different females was used to obtain an estimate of the heritability of resistance to death from gas bubble disease in Columbia River fall chinook salmon (Oncorhynchus tshawytscha). Heritability estimates ranged from 0. 037 to 0. 038. Bioassays...
