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...
Las polillas pueden dañar la ropa y otros artículos. Hay dos especies comunes de polillas en el Noroeste del Pacífi co: la polilla tejedora (Tineola bisselliella) y la polilla del estuche, también conocida como polilla capullera (Tinea pellionella). Son las larvas las que hacen daño.
In some homes, clothes moths can damage garments and other belongings. There are two common species of clothes moths in the Pacific Northwest: the webbing clothes moth (Tineola bisselliella) and the casemaking clothes moth (Tinea pellionella). The larvae,
or immature form, of the moths are responsible for the damage done...
A substantial portion of the carbon (C) emitted by human activity is apparently being stored in forest ecosystems in the Northern Hemisphere, but the magnitude
and cause are not precisely understood. Current official estimates of forest C flux are based on a combination of field measurements and other methods. The...
We explore the optimal time path of carbon sequestration and carbon abatement in stabilizing
CO₂ levels under uncertainty of climate impacts. Using a two-period sequential decision making
model, we analytically derive optimal rates for the two control variables, abatement and
sequestration rates. Uncertainty is assumed to affect the desired future...

IPM stands for “Integrated Pest Management,” a common-sense pest management strategy that focuses on long-term solutions to pest problems with minimum impact on human health and the environment. In an IPM approach, pesticides are not relied upon as the only response to a pest problem, but are part of an...
Estimating the stock proportions of mixed-stock fishery samples by means of genetic stock identification has played an important role in the management of salmon fisheries. In addition, stock identification of individual fish has applications for population studies, forensic cases, and management issues. We examined 11 microsatellite DNA loci in 84...
We used microsatellite DNA data and genetic stock identification methods to delineate the temporal and spatial distributions of juvenile Chinook Salmon Oncorhynchus tshawytscha occupying coastal habitats extending from central Oregon to northern Washington. Juveniles were collected in trawl surveys conducted during spring, summer, and autumn over 15 years. Distributions (mean...
