Resident cutthroat trout in the central Coast Range of Oregon : logging effects, habitat associations, and sampling protocols

Creator:: Connolly, Patrick John, 1955-
Abstract:: Populations of coastal cutthroat trout, Oncorhynchus clarki clarki, were sampled in 16 headwater streams from logged (20-30 and 40-60 years ago) and unlogged (stand age 125-150 years) basins. Basins logged 20-30 years ago supported the widest range of mean biomass of age 1+ or older cutthroat trout (g/m2) and the...

Geochemical cycling in a Pacific Northwest estuary (Tillamook Bay, Oregon, USA)

Creator:: Colbert, Debbie L.
Abstract:: This thesis investigates the behavior of major inorganic nutrients (P, N, Si), trace metals (Mn, Fe), and alkaline-earth metals (Ba) within Tillamook Bay over seasonal cycles and under a range of river discharge conditions from October 1997 through December 1999. Located in the Pacific Northwest region, Tillamook Bay is an...

Effects of light, nutrients, and grazing on periphyton communities in streams

Creator:: Gregory, Stanley Vincent
Abstract:: Relative effects of light, nutrients, and grazing on primary production were investigated in streams in the Cascade Mountains of Oregon and in laboratory streams. Relative magnitudes of primary production and associated processes were examined for one year in a stream that flowed through a clearcut and an old-growth forest in...

Prey availability overrides cover in determining growth and abundance of stream-dwelling cutthroat trout

Creator:: Wilzbach, Margaret A.
Abstract:: The abundance and biomass of cutthroat trout (Salmo clarki) have been found to be greater in logged than in forested streams of the Oregon Cascades. Although certain prey taxa increase in abundance following logging, habitat stability generally decreases and cover structures are removed. Research was conducted to examine the manner...

Investigations of T cell costimulation and autoimmunity in mice, and development of flow cytometric methods to assess lymphocyte stimulation in dogs

Creator:: Weatherill, Amy R.
Abstract:: Proper immune function is indispensable, as failure to mount an immune response against a pathogen can lead to serious complications or even death. T cells act by enhancing the activation of phagocytic cells as well as the activation of B cells. Their widespread influence on an immune response makes optimal...

New insights on an old topic : understanding the effects of forest harvest on trout in the context of climate

Creator:: Penaluna, Brooke E.
Abstract:: Studies of the effects of forest harvest on streams and fish have a long history in the Pacific Northwest. Results of this work have prompted development of new forest harvest practices that are more protective of these resources, but the effectiveness of these new practices has not been fully evaluated....

Succession and stability in two rocky intertidal communities on the central Oregon coast

Creator:: Farrell, Terence M.
Abstract:: The stability of a limpet-dominated community was assessed in a experiment in which an consumer was temporarily removed. Compared to unmanipulated plots, the limpet-exclusion plots developed greater algal abundance and altered species composition of both algae and barnacles. The community was not perturbed beyond its capacity to recover, since the...

Effects of sampling design, estimators, and variability on groundfish management in Oregon

Creator:: Crone, Paul R. Jr
Abstract:: Sampling error associated with estimates of species composition and age composition of commercial groundfish landings in Oregon from 1989 to 1991 is documented to evaluate the impact of variable landing data on fisheries management and monitoring programs. The statistical reliability and bias associated with two multistage sampling designs are investigated...
