Though the commercial value per pound of Pacific halibut (Hippoglossus stenolepis) is greater than that of most target species in trawl fisheries off Alaska, halibut retention is prohibited for trawlers and individual groundfish target trawl fisheries are subject to closure if they attain either their seasonal or annual limit of...
To quantify total fishing mortality it is necessary to incorporate mortality rates attributed to bycatch,
including animals that are discarded and that interact with the gear without being caught. The Reflex
Action Mortality Predictor (RAMP) approach has been increasingly used to determine bycatch mortality
rates in fisheries. This methodology creates...
The purpose of this study was the development of the Sex Role
Learning Index (SERLI), a picture choice instrument for assessing the
concepts of sex role discrimination, preference, and confirmation in
young children. The SERLI consists of 60 black-and-white line drawings
depicting common objects, child activities and adult activities
and...
An unique opportunity to investigate wind flow
patterns and calm air patterns arose from the acquisition
of a survey by Clarence L. Smalley on air flow patterns in
the San Francisco Bay area from 1952 through 1955. An
analysis was made of the wind patterns and calms in the study...
"In the past 6 years research effort on the Marbled Murrelet (Brachyramphus marmoratus) has increased in response to an apparent dramatic decline in their numbers on the west coast south of British Columbia (Marshall, 1988, Carter and Erickson 1992, Nelson et al. 1992). Their recent listing as a federally threatened...

Polycentric networks of formal organizations and informal stakeholder groups, as opposed to centralized institutional hierarchies, can be critically important for strengthening the capacity of governance systems to adapt to unexpected social and biophysical change. Adaptive governance is one type of environmental governance characterized by the emergence of networks that stimulate...
