Breeding matters: Natal experience influences population state-dependent host acceptance by an eruptive insect herbivore
Download2017-01-01
Burke, Jordan Lewis, Carroll, Allan L.
Eruptive forest insects are highly influential agents of change in forest ecosystems, and their effects have increased with recent climate change. State-dependent life histories contribute significantly to the population dynamics of eruptive forest insect herbivores; however, the proximate...

Brown Bear (Ursus arctos) Predation of Broad Whitefish (Coregonus nasus) in the Mackenzie Delta Region, Northwest Territories
Download2009
On 2 October 2007, we observed evidence of at least one brown bear (Ursus arctos) predating and caching broad whitefish (Coregonus nasus) at Pete’s Creek, a tributary of the Mackenzie River, Northwest Territories. While predation on whitefish by brown bears has been reported as traditional...

Changes in net ecosystem productivity and greenhouse gas exchange with fertilization of Douglas fir: Mathematical modeling in ecosys
Download2010
Bruemmer, C., Jassal, R. S., Grant, R. F., Black, T. A.
Abstract: The application of nitrogen fertilizers to Douglas fir forests is known to raise net ecosystem productivity (NEP), but also N(2)O emissions, the CO(2) equivalent of which may offset gains in NEP when accounting for net greenhouse gas (GHG) exchange. However, total changes in NEP and...

Could Age, Sex and Physical Fitness Affect Blood Glucose Responses to Exercise in Type 1 Diabetes?
Download2019-11-13
Yardley, J. E., Brockman, N. K., Bracken, R. M.
Closed-loop systems for patients with type 1 diabetes are progressing rapidly. Despite these advances, current systems may struggle in dealing with the acute stress of exercise. Algorithms to predict exercise-induced blood glucose changes in current systems are mostly derived from data involving...

Cyathea cranhamii sp. nov. (Cyatheaceae), Anatomically Preserved Tree Fern Sori from the Lower Cretaceous of Vancouver Island, British Columbia
Download2003
Stockey, Ruth A., Rothwell, Gar W., Smith, Selena Y.
Permineralized cyatheaceous sori occur among remains of conifers, fungi, and other plants in newly discovered calcareous concretions from Early Cretaceous (Barremian) marine sediments of Vancouver Island, British Columbia, Canada. Sori are superficially attached in two rows to narrow pinnules and...

Definition and interpretation of fact in Canadian Aboriginal title litigation: A comment on Delgamuukw
Download1994
Asch, Michael, Bell, Catherine
Professors Asch and Bell argue that Aboriginal title litigation presents a unique set of evidentiary problems both for Aboriginal plaintiffs and the courts. The elements of proof of title are themselves imbued with an ethnocentrism which serves to ignore Aboriginal systems of land ownership and...

Evaluation of potential meteorological triggers of large landslides in sensitive glaciomarine clay, eastern Canada
Download2012-01-01
Hutchinson, D. J. , Gauthier, D.
Heavy rains spread over some interval preceding large landslides in sensitive glaciomarine clay in eastern Canada are often noted as a triggering or causative factor in case studies or research reports for individual landslides, although the quantity or duration of the triggering rain event has...

Ciarniello, L. M., Heard, D. C., Boyce, M. S., Seip, D. R.
The purpose of our study is to show how ecologists' interpretation of habitat selection by grizzly bears (Ursus arctos) is altered by the scale of observation and also how management questions would be best addressed using predetermined scales of analysis. Using resource selection functions (RSF)...

Landslides in weakly cemented glaciolacustrine sediments, Morkill River valley, British Columbia
Download2001
Abstract: Slopes in weakly cemented glaciolacustrine sediments in the Morkill River valley in the Canadian Rocky Mountains stand at up to 70 degrees. Based on field and laboratory observations it appears that a contributing factor to instability is the softening of the soils by frost action and...

Van Moorter, B., Mcloughlin, P. D., Gaillard, J. M., Duncan, P., Boyce, M. S., Delorme, D., Klein, F., Bonenfant, C., Messier, F., Said, S.
The relationship between individual performance and nonrandom use of habitat is fundamental to ecology; however, empirical tests of this relationship remain limited, especially for higher orders of selection like that of the home range. We quantified the association between lifetime reproductive...
