Efficient foraging strategies result in a predator spatially overlapping with its prey, foraging in the most profitable patches, and minimizing the time transiting between patches. Previous studies investigating baleen whale foraging strategies have generally focused on investigating spatial overlap with prey patches, patch profitability or movement within feeding grounds. The...
The National Oceanic and Atmospheric Administration (NOAA) Coastal Change Analysis Program (C-CAP) is developing a nationally standardized database on landcover and habitat change in the coastal regions of the United States. The Willapa Bay eelgrass mapping project was granted to the Columbia River Estuary Study Task force (CREST) of Astoria,...
The growth of bdellovibrios at the expense of the host organism involves the catabolism of host cell macromolecular components and the subsequent anabolistic incorporation into bdellovibrio progeny. Extracellular enzymes specific for the various substrates provided by the host cell are present. In this study the extracellular RNase of Bdellovibrio bacteriovorus...
One-minute rainrates were measured during two winter rainy
seasons in western Oregon to gain insights into the time-structure of
Oregon rainstorms. The averages of three non-dimensional relative
variance statistics were greater on the coast than inland. Rainrate
distributions showed that a greater portion of the total rain fell, at
higher...
The objective of this study was to ascertain the magnitude and
distribution of rainfall over coastal waters of the northwestern United
States and to compare values with those at nearby land stations.
Precipitation was measured with gauges at Totem, rainfall amounts
were assessed from weather reports at lightships off the...
The Elliott State Forest, located in the Coast Range of Oregon, is currently revising their Habitat Conservation Plan (HCP). Many of the constraints in the HCP are spatial, requiring identification of specific parcels in order to limit activity along habitat reserves, limit harvest opening size, and to coordinate activities within...
A review of current computer performance and evaluation techniques reveals a lack of an acceptable analytic tool for optimal computer system performance and evaluation. A generalized approach to the formulation of a third generation computer system model is proposed. The approach is used to optimize computer resource utilization and to...
