Cognitive and other neural processes emerge from the interactions be- tween neurons. Major advances have been made in studying networks in which the interac- fions occur instantaneously by means ofgraded synapses (Guckenheimer and Rowat, I 997). In other networks, the interaction between neurons involves time-delayed signals (action potentials or spikes)...
Abnormalities including contortion of the body and reduction of the jaws and pectoral
fins occurred among 2-25% of the yolk-sac Pacific herring larvae Clupea harengus pallasi collected in 1985 from Kulleet Bay, a spawning area on Vancouver Island, British Columbia. An additional 4-68% of the post-yolk-sac larvae had underdeveloped lower...
The Hatfield Marine Science Center (HMSC) is an interagency campus in Newport, Oregon with
a mission of research, education and outreach in marine sciences through collaborative
partnerships. Located on a 49 acre site on Yaquina Bay, Oregon, it is adjacent to diverse
habitats, many of which are subject to action...
In ocean fisheries for Pacific salmon Oncorhynchus spp., there can be several forms
of gear-related mortality. Much research effort has been directed at estimating mortality rates for salmon that are hooked and then released. Also potentially important but not easily measured is mortality of fish that escape from the hook...
Assessments for many U.S. Pacific coast groundfish stocks have been developed using the statistical catch-at-age method known as Stock Synthesis. This study used Monte Carlo simulation and a fractional factorial experiment to evaluate the effects of input data errors and stock characteristics on bias and precision in estimates of ending...
The absence of a direct, long-term measure of individual Steller sea lion survival led to the development of implanted, delayed transmission satellite tags specifically for this species (Life History Transmitter, LHX). To assess possible effects of implant procedures and LHX tags, we undertook a two-stage approach to monitor: 1) immediate...
Stabilization of the Yaquina Bay shoreline along the northeastern edge of the Hatfield Marine Science Center (HMSC) campus became necessary to halt erosion that threatened both HMSC critical infrastructure (seawater storage tank) and public access to the HMSC Nature Trail. A Dynamic Revetment (gravel beach) was installed in November, 2011...
