This research focuses on contemporary and historical relationships between landscape change and human impacts in southwest Yukon, Canada, in order to bring to light the nature of cumulative social effects, and culturally appropriate methodologies that may be used for their evaluation. Results were acquired through twenty eight semi-structured interviews with natural resource managers, health and social workers, First Nations, and non-First Nations residents, in which resource development, and other important local markers of change were topics of discussion. Social thresholds are also developed from these results for their use in supporting resource management decisions. Resilience theory plays a center role in...
The high accumulation rate, nearly complete preservation and detailed chronology of the Eclipse ice core, Yukon Territory, Canada, are well suited for comparison of the glaciochemical record with instrumental time series of temperature, precipitation and sea-level pressure. Results of cross-correlation analysis of instrumental temperature records with the Eclipse delta 18O time series reveal a significant positive relationship between summer-time delta 18O at Eclipse and summer (April-September) temperatures in northwestern North America. The results indicate that the Eclipse delta 18O time series provides a better proxy for regional temperature than does the delta 18O time series from the Mount Logan ice-core record...

We used the Muskwa-Kechika Management Area in northeast British Columbia, Canada as a case study to determine potential conflicts between future resource development and high-value habitats of large mammals in an undeveloped boreal landscape. More than 50 % of high-value habitats for caribou, moose, elk, wolves and grizzly bears were located in Special Resource Management Zones, where natural resource developments could occur. We developed geographic information system (GIS) layers of potential forest resources, oil and gas, minerals, wind power, all resources combined, and roads; and quantified the proportions of high-value habitats overlapping these potentials. Greater proportions of high-value habitats across...

A long range dual frequency identification sonar (DIDSON-LR) was used to enumerate the chinook salmon escapement to the Big Salmon River in 2006, as well as determine associated run timing, and diel migration patterns. This was the second year of sonar operation at this site. The sonar site was located on the Big Salmon River at the same location as in 2005, approximately 1.5 km upstream of the confluence with the Yukon River. Partial weirs placed on both sides of the river were used to restrict fish passage through a 34 m opening. The sonar was configured to provide a 29º conical ensonified field, 40 m wide that covered the water column within the fish passage opening. A total of 7,308 (7,298 counted plus 10 extrapolated)...
