This study examines the long-term role of interference on stand development of Douglas-fir (Pseudotsuga menziesii [Mirb.] Franco) and red alder (Alnus rubra Bong.) planted mixtures in the Central Cascades of Oregon, USA. The two species are common associates in naturally regenerated and planted conifer stands in the Pacific Northwest. Due...
Marine protected areas (MPAs) have become a widely used tool for marine conservation and fisheries management. In coastal areas, it has become clear that the success of MPAs, and the achievement of sustainable fishery production, requires a combination of effective management and conservation frameworks, maintenance of decent fisheries livelihoods, and...
Managed fisheries are frequently structured on a sector by sector basis with each sector defined by the type of user or use, for example commercial, recreational and indigenous sectors. Management arrangements for a sector, however, may not be formally integrated with those for other sectors. Consequent competition between sectors for...
β-lactoglobulin (β-Lg), bovine serum albumin (BSA), α-lactalbumin
(α-Lac), and β-casein were adsorbed onto
silanized silica surfaces of low and high hydrophobicity
for 8 h, and β-Lg and BSA for 1 h. The surfaces were
incubated in buffer for 0, 5, 10, or 15 h and then contacted
with Listeria monocytogenes...
The infection intensity of the monogenetic trematode Gyrodactyus stellatus on laboratory held English sole (Parophrys vetulus) appeared to be influenced by handling stress, substrate, and starvation. In bioassays testing G. stellatus survival times in mucus and serum collected from laboratory held sole at different times during trematode infection, trematode survival...
The decision to bury high level nuclear wastes in deep geological formations
led to the study of the Hanford Nuclear Reservation as one of three possible sites for
the first nuclear waste repository in the United States. To adequately evaluate the
environmental impact of siting nuclear waste repositories in basalt...
Immunity in juvenile coho salmon (Oncorhynchus kisutch) was
evaluated after immunization against vibriosis by parenteral, oral or
immersion methods. Relative levels of immunity were determined by
protection of fish from experimental water-borne challenges with
Vibrio anguillarum and by serum agglutination titers. Coho salmon
eggs were exposed to bacterin during artificial...
To determine the invasion threat to the NE Pacific of marine algae arriving on Japanese debris from the 2011 Great Tōhoku Earthquake and Tsunami, my colleagues and I identified the algal species on 42 of the most heavily fouled debris items that landed on the shores of Oregon and Washington...
In a comparison of the mammalian and fish immune systems many similarities and differences are found. While most of the differences occur in the acquired or lymphoid arm of immunity, the nonlymphoid immune systems of fish and mammals share many similarities. For instance, both animal groups use phagocytic neutrophils and...
