Age and growth of cutthroat trout, Salmo clarki clarki Richardson, in the Rogue River, Oregon

Creator:: Tomasson, Tumi
Resource Type:: Masters Thesis

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....
Resource Type:: Dissertation

Ecological relationships among western Ephemerellidae : growth, life cycles, food habits, and habitat relationships

Creator:: Hawkins, Charles Patrick
Abstract:: The purpose of this study was to describe the life cycles, feeding ecology, and habitat use of western species in the mayfly family Ephemerellidae. Data were used to compare the ecological relationships and strategies among species and to examine patterns of adaptive radiation within the family. Data were further used...

Life history and feeding role of the xylophagous aquatic beetle, Lara avara LeConte (Dryopoidea:Elmidae)

Creator:: Steedman, Robert John
Abstract:: The purpose of this study was to document the life history of the xylophagous elmid beetle, Lara avara. and to estimate its contribution to wood degradation in Oregon streams. Field collections, mark-recapture, and laboratory rearing were used to determine details of the life cycle. Laboratory feeding studies and field population...

Ecology of aquatic habitats associated with stream margins

Creator:: Moore, Kelly M. S.
Abstract:: The morphology and ecological importance of habitats associated with the margin of third-order stream channels in the Oregon Cascades were studied in streams in three different riparian types: 450-year-old conifers, 40-year-old alder, and an open, herbaceous-dominated clearcut. Margins, backwaters, and side channels in streams create important habitat for fry of...

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...

Relationships between fish species distribution and habitat in the Willamette River drainage in western Oregon

Creator:: Kruse, Amy Ellen
Abstract:: The objectives of this study were to (1) describe physical environmental conditions and species composition at several sites along an Upstream/downstream gradient in a number of tributaries of the Willamette River in western Oregon; and (2) identify possible relationships between species distributional patterns and physical habitat parameters using detrended correspondence...
Resource Type:: Masters Thesis

Fisherman versus management : perceptions and conflicts in the salmon fishery

Creator:: Mrakovcich, Karina Lorenz
Abstract:: Fishermen's and managers' perceptions of fishery issues are an important factor to consider when studying conflicts between the two groups. According to theories of conflict management, differences in perceptions may cause situations to be characterized by misunderstanding and mistrust, and may add to the difficulties in managing the conflict. A...

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...
Resource Type:: Dissertation

The influence of fall-spawning salmon on growth and production of juvenile coho salmon rearing in beaver ponds on the Copper River Delta, Alaska

Creator:: Lang, Dirk W.
Abstract:: This thesis examined the influence of fall-spawning coho salmon on the density, growth rate, body condition, and survival to outmigration of juvenile coho salmon rearing in beaver ponds on the Copper River Delta, Alaska. During the fall of 1999 and 2000 fish rearing in ponds that received spawning salmon were...
