Creator:: Beardsley, George F., Jr. and Zaneveld, J. Ronald V.
Abstract:: The apparent optical properties of sea water are a set of measurables that describe the geometry of the submarine light field. These properties are related to the inherent optical properties—the volume attenuation coefficient and the volume scattering function—through the process of radiative transfer. A numerical approximation to the equation of...

Columbia Basin Heritage Fish Consumption Rates

Creator:: Harper, Barbara L. and Walker, Deward E., Jr.
Abstract:: The distinction between contemporary Native American fish consumption rates and original baseline heritage rates is important as heritage rates have long been recognized as a baseline relevant to the fishing tribes of the Pacific Northwest, and are generally protected by Treaties and case law. This paper reviews two approaches to...

Comparison of Contemporary and Heritage Fish Consumption Rates in the Columbia River Basin

Creator:: Harper, Barbara L. and Walker, Deward E., Jr.
Abstract:: Fish consumption rates (e.g., pounds or grams per day (gpd), or meals per week) are used in a variety of regulatory processes such as setting water quality standards. Many tribes still eat more fish than the general public, especially in in areas such as the Columbia River Basin which was...

Predicting fish recruitment from juvenile abundance and environmental indices

Creator:: Stige, Leif Christian, Hunsicker, Mary E., Bailey, Kevin M., Yaragina, Natalia A., and Hunt, George L., Jr.
Abstract:: Prediction of year-class strength is a critical challenge for fisheries managers. Theoretically, predictions of recruitment should be better when they are based on estimates of cohort size taken close to the age of recruitment and may improve if the effects of environmental factors that influence pre-recruit mortality are accounted for....

Clovis Age Western Stemmed Projectile Points and Human Coprolites at the Paisley Caves

Creator:: Jenkins, Dennis L., Davis, Loren G., Stafford, Thomas W., Jr., Campos, Paula F., Hockett, Bryan, Jones, George T., Cummings, Linda Scott, Yost, Chad, Connolly, Thomas J., Yohe, Robert M., II, Gibbons, Summer C., Raghavan, Maanasa, Rasmussen, Morten, Paijmans, Johanna L. A., Hofreiter, Michael, Kemp, Brian M., Barta, Jodi Lynn, Monroe, Cara, Gilbert, M. Thomas P., and Willerslev, Eske
Abstract:: The Paisley Caves in Oregon record the oldest directly dated human remains (DNA) in the Western Hemisphere. More than 100 high-precision radiocarbon dates show that deposits containing artifacts and coprolites ranging in age from 12,450 to 2295 ¹⁴C years ago are well stratified. Western Stemmed projectile points were recovered in...

Fertilization of Epichloë typhina stromata by mycophagous slugs

Creator:: Hoffman, George D. and Rao, Sujaya
Abstract:: Epichloë typhina, a fungal endophyte of cool season grasses, is heterothallic and an obligate out-crosser. In areas of endemism, its spermatia are moved between stromata of the two opposite mating types through egg-laying activities of Botanophila flies. In western Oregon, where the fungus was inadvertently introduced into seed-production fields of...
