Amendment of Gold Mine Tailings with Modified Humic Substances to Promote Soil Development and Plant Growth
Resource
To promote the establishment of vegetation, modified humic substances were added to gold mine tailings in rates of 2 g C kg -1, 3 g C kg -1 and 4 g C kg -1 tailings as an amendment. Growth chamber and...
An Interdisciplinary Approach to Describing Biological Diversity
Project

Organization:
This PhD project use multiple disciplinary traditions to develop comprehensive and united representations of caribou variation through an exploration of population genetics, phylogenetics, traditional...
An Interdisciplinary Approach to Describing Biological Diversity
Resource
Abstract The concept of biodiversity – the phenotypic and genotypic variation among organisms – is central to conservation biology. There is growing recognition that biodiversity does not exist in...
Benefits of Fertilization for White Spruce and Lodgepole Pine Trees Depend on the Reclamation Substrate – Overburden vs Tailings Sand
Resource
Nitrogen and complete fertilizer applications improved growth of white spruce on overburden sites. Fertilization did not, however, have an effect on lodgepole pine growth on tailings sand sites
Boreal Trees Can Grow on Saline Sites – Implications for Reclamation Success on Saline Soils
Resource
Both aspen and spruce grew on sites with very high salinity and pH deeper in the soil profile (i.e., 40-100cm), so long as surface soils were not highly saline and had adequate moisture and nutrients.
Coarse Woody Debris Increases Microbial Functional Diversity in Reclaimed Soils
Resource
Forest floor mineral soil mix had significantly greater soil microbial functional diversity than peat mineral soil mix. CWD increased microbial biomass and microbial functional diversity in both soil
Collaborative research and monitoring of migratory Eastern Cape Chruchill caribou
Project
Organization:
The Cape Churchill caribou herd, part of the Eastern Migratory caribou population, resides along the western coast of Hudson Bay and has been largely unstudied. However, they are locally important to...
Combining Science and Traditional Ecological Knowledge: Monitoring Populations for Co-Management
Resource
Using a combination of traditional ecological knowledge and science to monitor populations can greatly assist co-management for sustainable customary wildlife harvests by indigenous peoples. Case...

This project demonstrates how visual art can be used in combination with scientific and social science methods to examine the biocultural landscape of the Sahtú region of the Northwest Territories...
Creative Convergence: Exploring Biocultural Diversity Through Art
Resource
Demonstration of how visual art can be used in combination with scientific and social science methods to examine the biocultural landscape of the Sahtú region of the Northwest Territories, Canada.
Deeper Soil Salvaging Depths Produce Greater Cover of Native Plants than Shallow Salvage Depths on a Reclaimed Coal Mine Site
Resource
The deeper soil salvage depth (40 cm) was better than the shallow salvage depth (15 cm) at establishing a forest understory plant community characteristic of the boreal forest.
Denésoliné (Chipewyan) Knowledge of Barren-Ground Caribou (Rangifer tarandus groenlandicus) Movements
Resource
Semi-directed interviews relating to the traditional knowledge (TK) of barren-ground caribou ( Rangifer tarandus groenlandicus) movements were conducted with elders and hunters from the Denésôliné...
Fecal DNA, Hormones, and Pellet Morphometrics as a Noninvasive Method to Estimate Age Class: An Application to Wild Populations of Central Mountain and Boreal Woodland Caribou (Rangifer tarandus Caribou)
Resource
Study tests a noninvasive method via fecal DNA, hormones, and pellet morphometrics to distinguish calf from adult in Central Mountain and Boreal woodland caribou populations.
Genetic Influences on Male and Female Variance in Reproductive Success and Implications for the Recovery of Severely Endangered Mountain Caribou
Resource
Assessment of three endangered caribou subpopulations using non-invasive genetic sampling to assess demographic population changes.
Monitoring Barren-Ground Caribou Body Condition with Denésǫłıné Traditional Knowledge
Resource
Information from aboriginal elders and hunters on changes in barren-ground caribou ( Rangifer tarandus) body condition can assist current management systems. Interviews with Denésǫłiné elders and...
Organic Amendment Effects on Productivity of Wellsites Reclaimed with Suboptimal Topsoil Replacement Depth in Northeasten Alberta
Resource
Reclamation and revegetation of boreal sites disturbed by oil exploration depend on the availability of topsoil salvaged on-site during the disturbance. For successful reclamation, current regulations...

Resource
The 13th North American Caribou Workshop in 2010 was the venue for a remarkable forum of Aboriginal knowledge holders in which experiences and ideas about caribou research and stewardship were shared...
Performance of Road Embankments on Seasonally-Frozen Peat Foundations With and Without Corduroy Bases
Resource
Two test sections along a newly constructed road embankment on peat foundations were instrumented to investigate their performance and to develop more economical means of construction method.
