Core-top benthic foraminifera (Cibicidoides wuellerstorfi) from a depth transect of Soutar box cores from the Ontong-Java Plateau (1.6 – 4.4 km) were analyzed for cadmium, barium, and strontium (Cd/Ca, Ba/Ca, and Sr/Ca) and for their stable isotopic composition (δ¹³C and δ¹⁸O). We also measure bottom water δ¹³C, Cd, and Ba...
A descriptive model of the routing of sediment that was
delivered to the study area by the 1980 eruptions of Mount St.
Helens has been developed. On hillslopes this sediment was
distributed among three major storage compartments: 1) the tephra
profile, 2) primary storage, and 3) secondary storage. The most...
This report was prepared for the 2009 Range Field Day held at the Central Oregon Agricultural Research Center in Madras, Oregon. It contains research reports on production of vegetable seed, grass seed, forage and cereals, and potatoes and peppermint; potential new crops; and rangeland and non-crop areas.
Upper Klamath Lake (UKL) and Agency Lake in south-central Oregon are hypereutrophic due to phosphorus (P) loading from both geologic and agricultural sources in the watershed. Restoring historic lake-fringe wetlands to provide P sinks around the lakes has been accepted as a favorable means of reducing lake P levels and...
All individuals are part of a family, and are confronted with
all the complexities that accompany family life during some portion
of their lifetime. Thus, inter-relationships between all family
members are an important aspect of education.
The school curriculum should be relevant to the needs of youth.
Family life education...
Despite progressive policies and continued advances in ocean management, numerous shifts associated with global changes have been observed in marine ecosystems in recent years, including warming, ocean acidification, and deoxygenation. As global change accelerates, science is needed to inform evidence-based management strategies for continued ecosystem services. Resilience management, in which...
As fisheries management shifts to an ecosystem-based approach, understanding energy pathways and trophic relationships in the Northern California Current (NCC) will become increasingly important for predictive modeling and understanding ecosystem response to changing ocean conditions. In the NCC, pelagic forage fishes are a critical link between seasonal and interannual variation...
Silviculture systems that involve commercial thinning may provide higher quality wildlife habitat than traditional clearcut systems, yet such systems have not been vigorously tested. This prospective study examined forest floor animal abundance and habitat relationships under three different silviculture conditions: clearcuts, commercial thins, and uncuts. Eighteen stands, six per treatment,...
Effects of climate change, retreating glaciers, and changing storm patterns on debris flow hazards concern
managers in the Cascade Range (USA) and mountainous areas worldwide. During an intense rainstorm in
November 2006, seven debris flows initiated from proglacial gullies of separate basins on the flanks of Mount
Rainier. Gully heads...
