Predator and shelter-size effects on coral reef fish and spiny lobster prey

Creator:: Eggleston, David B., Lipcius, Romuald N., and Grover, Jill J.
Abstract:: Population dynamics of coral reef fishes and spiny lobster appear to be determined by variable recruitment interacting with post-settlement processes, particularly predation. The risk of predation may be modified by the scaling between prey and shelter size, which enhances the protective capacity of a reef. We experimentally tested these predictions...

Market Information and Fisheries Management: A Multiple-Objective Analysis

Creator:: Sylvia, Gilbert
Abstract:: Market issues are often critical to the regional and national benefits that can be generated from fisheries management. In actual policy analysis, however, market considerations are often treated as exogenous to the fisheries policy problem. Examples illustrate the relationships between product characteristics, market demand, and regulatory management. A multiple-objective socioeconomic...

Is there a common response to ultraviolet-B radiation by marine phytoplankton?

Creator:: Behrenfeld, Michael J., Chapman, John W., Hardy, John T., and Lee II, Henry
Abstract:: Global increases in ultraviolet-B radiation (UVBR) have the potential to alter marine primary production and to affect carbon cycles and marine trophic dynamics. Estimates of UVBR induced photoinhibition have varied greatly, indicating that a common dose-response by marine phytoplankton may not occur from place to place. An action spectrum describing...

Gear-Related Mortality in Selective Fisheries for Ocean Salmon

Creator:: Lawson, Peter W. and Sampson, David B.
Abstract:: 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...
