With a warming climate, northern ecosystems will face significant ecological changes such as permafrost thaw, increased frequency of forest fires, and shifting ecosystem boundaries including the spread of canopy-forming shrubs into tundra communities. A growing number of observations show...
Examines Dawson City in terms of its history dating from the Klondike Gold Rush to its contemporary revival as a tourist attraction and a regional government centre.
A new species of Pinus Subgenus Pinus Subsection Contortae from Pliocene sediments of Ch'ijee's Bluff, Yukon Territory, Canada.Download
Three structurally preserved conifer ovulate cones are described from Pliocene sediments at Ch’ijee’s Bluff on the Porcupine River, near Old Crow, Yukon Territory, Canada. Cones are ovoid to conical, symmetrical, 3.4–4.4 cm long and 2.8–3.4 cm wide, with helically arranged cone-scale complexes....
Management issues pertaining to the use of northern national parks: a case study of the northern YukonDownload
Masters thesis. An examination of management issues which might arise through the use of a proposed national park in the northern Yukon by native people, researchers and wilderness recreationists.
Doctoral thesis. Critically reviews the art of phytolith analysis and presents new techniques to collection of samples, processing, mounting, and optical and SEM microscopic analyses. Includes results of analyses of samples from the Old Crow Basin, Yukon and lake areas in Alaska.
Report of study to provide qualitative and some quantitative observations of design and performance of Dempster Highway in Yukon and NWT 5 years after construction of its final phase (1979). Also suggests engineering recommendations and design improvements to alleviate problems arising from...
This thesis contributes to the development of a cryptotephra framework in northwestern North America, providing the initial data for the construction of a regional cryptotephra framework where key cryptotephra layers (those which are widely distributed, easily correlated, and have well...
Masters thesis. Pollen analysis of an alluvial exposure along the Bluefish River gives further information on the paleoecological changes that have taken place in the interior Yukon and Alaska during the Quaternary.
An analysis of the natural vegetation of the Macmillan Pass/Sheldon Lake area of the east-central Yukon TerritoryDownload
Data collected for use in the vegetation component of a biophysical inventory of the Macmillan Pass/Sheldon Lake region is presented and discussed in order to classify and describe the vegetation communities of the area and to postulate on the environmental factors which control the distribution...
Dall sheep (Ovis dalli dalli), grizzly bear (Ursus arctos) and wolf (Canis lupus) interactions in the Northern Richardson Mountains, CanadaDownload
Assessing the impact of predators on a prey population is inherently challenging, a fortiori in remote ecosystems. With this thesis, I studied the interactions between a recently declining Dall sheep (Ovis dalli dalli) population and two predators: grizzly bears (Ursus arctos) and wolves (Canis...
