By the terms set by international agreements for the conservation of Yukon River salmon, 2009 was a management success. It was a devastating year for many of the Alaska Native communities along the Yukon River, however, especially in up-river communities, where subsistence fishing was closed in order to meet international conservation goals for Chinook(More)
Global climate change has the potential to substantially alter the production and community structure of marine fisheries and modify the ongoing impacts of fishing. Fish community composition is already changing in some tropical, temperate and polar ecosystems, where local combinations of warming trends and higher environmental variation anticipate the(More)
Many believe commercial fisheries in Alaska (U.S.A.) are sustainability success stories, but ongoing socioeconomic problems across the state raise questions about how this sustainability is being defined and evaluated. Problems such as food insecurity and the disenfranchisement of Alaska Natives from fishing rights are well documented, yet these concerns(More)
Computational thinking (CT) is a way to solve problems and understand complex systems that draws on concepts fundamental to computer science and is well suited to the challenges that face researchers of complex, linked social-ecological systems. This paper explores CT's usefulness to sustainability science through the application of the services-oriented(More)
iii ABSTRACT This thesis is a combined volume containing three individual research papers, each written for submission to a different peer-reviewed journal. Each to some extent investigates community resiliency and vulnerability as they manifest in the past and present of Alaska Native foodways. The first paper, 'Outpost Gardening in Interior Alaska'(More)
BACKGROUND Multiple climatic, environmental and socio-economic pressures have accumulated to the point where they interfere with the ability of remote rural Alaska Native communities to achieve food security with locally harvestable food resources. The harvest of wild foods has been the historical norm, but most Alaska Native villages are transitioning to a(More)
Northern peoples face a difficult decision of whether or not to consume wild fish, which may contain dangerous levels of contaminants such as methylmercury (MeHg), but which also offer a number of positive health benefits, and play an important role in rural household economies. Here, new methods for developing consumption advice are applied to an existing(More)
CONTEXT Effective management of environmental risks such as food and water contamination requires both high quality scientific information and effective, informed social policy. Not only must health practitioners and policy-makers recognize the complexities of human health as a social phenomenon, they must also negotiate the vagaries of uncertainty,(More)
Understanding the impacts of recreational fishing on habitats and species, as well as the social and ecological importance of place to anglers, requires information on the spatial distribution of fishing activities. This study documented long-term changes in core fishing areas of a major recreational fishery in Alaska and identified biological, regulatory,(More)
