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...

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...

Potential effects of climate change on tree species and ecosystem distribution in British Columbia
Download2006
A new ecosystem-based climate envelope modeling approach was applied to assess potential climate change impacts on forest communities and tree species. Four orthogonal canonical discriminant functions were used to describe the realized climate space for British Columbia's ecosystems and to model...

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)...

Storm surge flooding: risk perception and coping strategies of residents in Tsawwassen, British Columbia
DownloadSpring 2010
This thesis examines how residents perceived and coped with storm surge flooding in Tsawwassen, British Columbia. On February 4, 2006 the community experienced a storm surge flood that affected residents within the neighbourhoods of Beach Grove and Boundary Bay Village. This study identifies...

Net ecosystem productivity of temperate and boreal forests after clearcutting - a Fluxnet-Canada measurement and modelling synthesis
Download2010
Barr, A. G., Trofymow, J. A., McCaughey, J. H., Black, T. A., Margolis, H. A., Grant, R. F.
Abstract: Clearcutting strongly affects subsequent forest net ecosystem productivity (NEP). Hypotheses for ecological controls on NEP in the ecosystem model ecosys were tested with CO(2) fluxes measured by eddy covariance (EC) in three post-clearcut conifer chronosequences in different ecological...

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...

Applications of learning theory to human-bear conflict: the efficacy of aversive conditioning and conditioned taste aversion
DownloadSpring 2011
I tested the efficacy of aversive conditioning (AC) and conditioned taste aversion (CTA) on American black bears (Ursus americanus) in Whistler, British Columbia. Black bears subjected to 3-5 day AC programs responded by increasing their wariness toward humans, while control bears habituated. ...

Spring 2011
Quantification of the effects of residual forest structure on the understory light environment is needed to guide silvicultural strategies that facilitate regeneration. In this study I measured understory light using various methods in a dry, uneven-aged mixed conifer forest in British Columbia,...
