The purpose of this report is to describe a large tumor complex that was found protruding into the pericardial cavity of a single Ostrea lurida from Yaquina Bay, Oregon.
The copepod Tigriopus californicus shows extensive population divergence and is becoming a model for understanding allopatric differentiation and the early stages of speciation. Here, we report a high-quality reference genome for one population (similar to 190 megabases across 12 scaffolds, and similar to 15,500 protein-coding genes). Comparison with other arthropods...
Douglas-fir (Pseudotsuga menziesii var. menziesii (Mirb.) Franco) growth in the Pacific Northwest is affected by climatic, edaphic factors and Swiss needle cast (SNC) disease. We examine Douglas-fir growth responses to temperature, dew point deficit (DPD), soil moisture, and SNC using time series intervention analysis of intra-annual tree-ring width data collected...

Time was the most significant factor influencing brush and grass change inside and outside cattle exclosures over a 37-year period (1937-1974).
The 10 exclosures (2 ha) represent the big and low sagebrush (A. tridentata and A. arbuscula) Qunchgrass vegetation of eastern Oregon and were established on the Squaw Butte Experiment...
During the W7711A cruise, from November 5 through November
13, 1977, a series of measurements were made on the hydrography, suspended particulate matter (spm), nutrients, first and second trophic level biomasses, primary productivity and zooplankton species for the purpose of gaining concurrent winter time information on these parameters. The cruise...
Spectral attenuation and absorption coefficients of particulate matter and collocated hydrographic measurements were obtained in the Mid-Atlantic Bight during the fall of 1996 and the spring of 1997 as part of the Coastal Mixing and Optics experiment. Within the bottom boundary layer (BBL) the magnitude of the beam attenuation decreased...
