Today, decentralization and democratic participation are presented as necessary conditions to achieve poverty alleviation and ensure the sustainable use of our diminishing natural resources. In small-scale
fisheries, similar ideas predominate and decentralization has become the new management paradigm through the concepts of community-based and co-management. In this paper, we present...
Stock assessments use statistical models and empirical data to re-create the population dynamics of a stock in order to provide estimates of biomass and fishing mortality rates to inform fisheries management. Fish stocks are not uniformly distributed across spatial regions, but stock assessments typically ignore stock spatial structure, for the...
The relationship between population characteristics and population productivity is fundamental to sustainable fisheries management, but predicting productivity remains a challenging task. Proposed mechanisms driving the variability in productivity at a given population size have included environmental and demographic factors related to the age structure of the population, but the broad-scale...
Due to the effective antimicrobial properties of silver nanoparticles they represent a significant proportion of all consumer-‐related nanomaterials. The introduction of silver nanoparticles from these products into domestic and industrial wastewater streams poses potential complications for biological treatment systems. A critical component of biological treatment that is extremely sensitive to...
This paper describes the analysis of data from a three-year gross time study of skyline, balloon, and helicopter yarding systems operating in Western Oregon. Data collection activities were designed and supervised by the Pacific Northwest Forest and Range Experiment Station, U.S.D.A. Forest Service. The specific logging systems studied were running...
Numerous flights of Quaternary marine terraces are present around the island of Cyprus, in the Eastern Mediterranean. These terraces are a result of the global eustatic sea-level curve and local tectonism. Marine Isotope Stage (MIS) 5 through MIS 13 terraces are identified, mapped and dated. Palaeoshoreline elevation, an excellent indicator...
Oyster relaying is one of the means by which oystermen increase the net return from their leases. Using a Poisson regression model, this research evaluates the factors affecting the demand for relaying permits by the oyster industry in Louisiana, the nation’s leading oyster producing state. Economic factors and prevailing environmental...
This plant association guide has been developed as an aid for Forest Service resource managers to identify long term stable plant associations found on the Crooked River National Grassland. The guide describes in detail good, fair, and poor range condition on lands seeded to either crested wheatgrass or beardless wheatgrass...
