Marine mammals use acoustics for many life functions, including communication. Male fin whales produce a call around 20 Hz and the pattern of a series of calls can vary based on the individual, geographic region, and season. I examined the variation between songs in fin whales. A glider was deployed...
Floods are major disturbance events for riverine ecosystems, directly and indirectly impacting organisms and their habitat. In this study I investigated the role of riverine floods and flow alteration in regulating aquatic macroinvertebrate population and community structure. I examined this problem using a variety of methods: a meta-analytic review of...
Cnidarians, such as anemones and corals, engage in an intracellular symbiosis with
photosynthetic dinoflagellates. Corals form both the trophic and structural foundation of
reef ecosystems. Despite their environmental importance, little is known about the
molecular basis of this symbiosis. In this dissertation we explored the cnidariandinoflagellate symbiosis from two perspectives:...
English sole (Parophrys vetulus) is a flatfish found in abundance in the Pacific Ocean and is part of the Pacific Northwest's and California's commercial trawl fishery. Stock levels of this fish are at all time highs but there are decreased landings due to low demand and acceptability. With new regulations...
The efficacy of a new broad-spectrum anthelmintic, Netobimin[subscript R]
(coded SCH 32481-Schering Corporation) was evaluated in two trials
conducted during either the spring or fall grazing seasons of 1984 in
Western Oregon using 20 cross-bred yearling beef heifers and 30
cross-bred spring lambs, respectively. Percent efficacies were
determined in both...
Phytophthora species were systematically sampled, isolated, identified and compared for presence in streams, soil and roots of alder (Alnus species) dominated riparian ecosystems in western Oregon. We describe the species assemblage and evaluate Phytophthora diversity associated with alder. We recovered 1250 isolates of 20 Phytophthora species. Only three species were...
Epidemiological evidence has demonstrated a reduced risk of prostate cancer associated with cruciferous vegetable intake. Follow-up studies have attributed this protective activity to the metabolic products of glucosinolates, a class of secondary metabolites produced by crucifers. The metabolic products of glucoraphanin and glucobrassicin, sulforaphane and indole-3-carbinol respectively, have been the...

The Ni-les’tun tidal wetland restoration project in the Coquille River Estuary in southern Oregon is one of the largest and most well-studied tidal restoration projects on the Pacific Northwest coast. However, ecological data on restoration effectiveness and ecosystem change following restoration are relatively rare for projects more than a few...
