Abstract The Yukon River Drainage Fisheries Association (YRDFA) conducted a study to collect and utilize traditional ecological knowledge (TEK) held by people living in the villages along the Yukon River as an attempt to better understand changing salmon runs. The study took place during the summers of 2001 and 2002. Twenty-nine participants were interviewed in the four Yukon River villages of Alakanuk, Saint Mary’s, Holy Cross and Nulato. We collected information on local observations of salmon lifecycles, abundance, environmental change and habitat. Through this study we learned that participants are highly affected by the newly regulated subsistence schedule and that their detailed knowledge of their environment,...

Subsistence fishing and hunting are important for the economies and cultures of many families and communities in Alaska. Subsistence exists alongside other important uses of fish and game in Alaska, including commercial fishing, sport fishing, personal use fishing, and general hunting. This report provides an update on subsistence in Alaska, including the dual state-federal management system.

The Gwich'in consume traditional country foods as a main staple of their diet. Due to concerns from the Gwich'in with] regards to contaminants in the food chain, the Gwich'in Community Liaison (GCL) position was established. This position enabled the Gwich'in to be a member of and participate in research programs established by the Northern Contaminants Program (NCP). The Gwich'in Community Liaison will continue to promote dialogue and information between the Gwich'in communities, Gwich'in Organizations, NCP representatives, and NCP scientists. Gwich'in Tribal Council (GTC) GCL has participated in monthly Northwest Territories Environmental Contaminants Committee (NWTECC) meetings, liaison of relevant contaminant...
The health of caribou (Rangifer tarandus ) is impacted by multiple risk factors, which may affect availability of caribou for consumption. From analysis of secondary dietary intake data, consuming caribou was found to be positively related to measures of diet quality--caloric intake and dietary diversity score. Other country foods, beef, or pork may be substituted for caribou with increases in opportunity cost and out-of-pocket costs for obtaining caribou. Caribou consumption levels are predicted to vary across and within regions. Communities with older populations, lower employment rates and access to stores are likely to be impacted more by changes in the health of caribou. Analysis of federal survey data highlights...
This thesis addressed how Alaska Natives of the Iliamna Lake region have practiced subsistence and indigenous religious traditions to live sustainably in their local environments and how their ways of living have been practiced from the 1960s to 2013. Research was framed from the perspective of traditional ecological knowledge (TEK) to explore the residents' beliefs, practices, and the long-term observation of their local environment in Pedro Bay (predominantly Dena'ina) and Newhalen (predominantly Central Yup'ik). Research methods used included participant observations, key respondent interviews, and mapping exercises. Analysis of the qualitative data indicates that Pedro Bay and Newhalen residents have practiced...
ABSTRACT. Lightning and fire characteristics within the Northwest Territories (NWT) jurisdiction of the Mackenzie Basin between 1994 and 1999 are examined using data from the lightning detection network operating in the NWT and from the national Large Fire Database maintained by the Canadian Forest Service. The convective storm season with associated lightning activity over this region is short hut intense, with a strong peak in cloud-to-ground lightning during July. The maximum area of lightning activity is influenced by local moisture sources and by topography. The diurnal distribution of cloud-to-ground flashes indicates that most of the lightning was linked to thunderstorms initiated by daytime heating. The...
Pollen, spores, and dinoflagellate cysts are used with the modern analog technique (MAT) to provide paleoclimate reconstructions for terrestrial and marine environments in northeastern North America. Multivariate analysis of marine and nearby terrestrial pollen sequences from Hudson Bay, Labrador and the St. Lawrence, differentiate tundra, boreal and deciduous forest assemblages in time and space. These three regions had differing climate histories with respect to deglaciation and air mass boundaries. Prior to 6000 14 C yr BP, cooler temperatures reconstructed along the Labrador margins agree with climate simulations indicating a persistent anticyclone over the Québec-Labrador ice sheet. A late Holocene cooling...
Through a process of participatory mapping, this research assessed the impacts of the 1984 change in Alaska fire policy from one of exclusion to one of management on Native land use in the Yukon Flats National Wildlife Refuge. Findings suggest that while the change in policy has had little measurable effect on community land use the continued suppression of fire on Native owned lands is having a direct impact on the current availability of wildlife resources to the point of necessitating territorial expansion among Native resource users. However, given the complexity of human nature, the impacts associated with the 1984 policy change should not be reduced to a simplistic cause-and-effect relationship. Rather this...
