Effects of biotic feedback and harvest management on boreal forest fire activity under climate change
Predictions of future fire activity over Canada's boreal forests have primarily been generated from climate data following assumptions that direct effects of weather will stand alone in contributing to changes in burning. However, this assumption needs explicit testing. First, areas recently burned can be less likely to burn again in the near term, and this endogenous regulation suggests the potential for self-limiting, negative biotic feedback to regional climate-driven increases in fire. Second, forest harvest is ongoing, and resulting changes in vegetation structure have been shown to affect fire activity. Consequently, we tested the assumption that fire activity will be driven by changes in fire weather without...
Forest tenures and their implications for exercising Aboriginal and treaty rights on the Kaska traditional territory
This study identifies potential changes within the current tenure system to better accommodate Aboriginal values. Aboriginal expectations for sustainable forest management were identified using structured conceptual content cognitive mapping. A structured survey of industry, government and First Nations participants was then used to identify Aboriginal expectations that are poorly met through the current tenure system and establish which attributes of tenure could be modified in order to meet these expectations. Perception gaps existed between the Kaska and government/industry about the ability of current forest management institutions to meet Aboriginal expectations. Some of the expectations were met in part by...
Hunting, herding, fishing and gathering: indigenous peoples and renewable resource use in the Arctic
Climate change interactions at the edge: Wildfire and subsistence in the Boreal Forest, and sea-level rise and nitrogen loads at the California land-sea margin
My dissertation furthers work in ecosystem resilience and social-ecological resilience to global change, in the systems of a) the northern boreal forest of interior Alaska, where climate change drives a changing wildfire regime; and b) a central Californian estuary, where N pollution and sea-level rise (due to climate change) converge at the land-sea interface, impacting rare salt marsh habitats and their provision of ecosystem services. The first study explores impacts of a changing wildfire regime on a suite of wild species important for subsistence livelihoods, including game animals, furbearers, fish, and plants. Fire is a primary determinant of landscape pattern in the boreal forest. My review of 17 species...
Subsistence Hunting and Fishing in Alaska: Does ANILCA's Rural Subsistence Priority Really Conflict with the Alaska Constitution
All parties to the subsistence controversy in Alaska (the state and the federal government, sportsmen’s associations, outdoor organizations, and Native groups) have assumed that the Alaska National Interest Lands Conservation Act (ANILCA) grants residents of rural Alaska an exclusive right to engage
Presents a study that documented the traditional ecological knowledge of the Alaska Native hunters of beluga whales in Cook Inlet to add information available on the population. Importance of summer feeding to Cook Inlet belugas; Predation by killer whales; Information on beluga cows and calves.
"They left their teacups full and their zeniths in the house" : Innoko River population movements and migrations
Summary: "This thesis discusses the history of population movements and migrations on the middle and upper Innoko River in west-central Alaska. The history of research and exploration into the region is synthesized. The bodies of work known as 'place attachment studies' and 'place studies' are presented as a framework with which to understand current perceptions of the movements and migrations. The move from Holikachuk village on the Innoko River to Grayling on the Yukon River in 1963 is examined in detail. The long-term consequences of these movements for the Holikachuk Athabascan people are analyzed"
Use of Traditional Foods in a Healthy Diet in Alaska: Risks in Perspective; Second Edition: Volume 1. Polychlorinated Biphelyls (PCBs) and Related Compounds
The Alaska Division of Public Health recommends the continued unrestricted consumption of traditional subsistence foods in Alaska. Traditional foods provide inexpensive and readily available nutrients, essential fatty acids, antioxidants, calories and protein and many health benefits such as protection from diabetes, cardiovascular disease, improved maternal nutrition, and neonatal and infant brain development. Presence of heavy metals and persistent, man-made chemicals in the arctic food chain generated concerns about the potential threat to the ecosystem and risk to human health. The global distribution of man-made pollutants through atmospheric transport is well documented; human exposures to them in the arctic...
Quantifying fire-wide carbon emissions in interior Alaska using field measurements and Landsat imagery
Carbon emissions from boreal forest fires are projected to increase with continued warming and constitute a potentially significant positive feedback to climate change. The highest consistent combustion levels are reported in interior Alaska and can be highly variable depending on the consumption of soil organic matter. Here we present an approach for quantifying emissions within a fire perimeter using remote sensing of fire severity. Combustion from belowground and aboveground pools was quantified at 22 sites (17 black spruce and five white spruce-aspen) within the 2010 Gilles Creek burn in interior Alaska, constrained by data from eight unburned sites. We applied allometric equations and estimates of consumption...

Local level criteria and indicator frameworks: A tool used to assess aboriginal forest ecosystem values
Although the importance of aboriginal knowledge, values and perspectives in sustainable development has been recognised for many decades, worldwide examples exist showing that aboriginal involvement is less then effective. How and where to include aboriginal needs and goals has however been problematic. Ultimately, aboriginal forest values need to be considered with scientific strategies and their role and compatibility with forest conditions needs to be explored. Criteria and indicator (C&I) frameworks can be used as a platform to include community needs and goals in management decisions. This review compares aboriginal forest ecological perspectives defined by Canadian local level C&I frameworks with non-aboriginal...
