Disturbance Effects of Oil Sands Exploration Practices on Coarse-textured Soils and Populus tremuloides Michx. RegenerationDownload
Oils sands exploration (OSE) sites associated with in situ oil sands development are required to evaluate and delineate oil resources. Once these sites are cleared and disturbed for exploration, they can result in habitat disturbance and fragmentation, invasion of weed species, changes to surface...
Challenges of utilizing municipal compost as an amendment in boreal forest reclamation subsoil materialDownload
Forest reclamation sites are often located in areas not suited for agriculture and therefore have poor soil conditions. To assist in the rehabilitation of forests on these types of sites, organic amendments can be used. Close to large urban centers, compost derived from municipal organic waste...
Investigating fine-scale movement patterns and comparative swimming performance of the newly identified and threatened Rocky Mountain Sculpin (Cottus sp.) across its Canadian distributionDownload
Cumulative anthropogenic impacts to the riverscape, including hydrologic alteration, have contributed to an escalated number of freshwater fish species at risk in North America. Species dispersal is an important mechanism underlying many ecological processes. Understanding the scale at which...
Effective and adaptive conservation of a species requires knowledge of trend in abundance and distribution. Monitoring species that are highly mobile, cryptic, and occurring at low densities is especially challenging. This research investigates the local factors affecting the detectability of...
Water availability and understory influence on tree growth in reclaimed forest ecosystems, Athabasca oil sands region, Alberta, CanadaDownload
Reclaimed forest ecosystems in the Athabasca oil sands region (AOSR) have limiting factors to growth that can result in poor tree performance, as indicated by stunted growth, foliar discolouration and needle dropping, and ultimately threaten reclamation success. Indicators of reclamation success...
Oil sands extraction and refining can cause many negative environmental impacts and because these activities usually take place in the forest region, the Government of Alberta requires that, after mine sites are closed, the companies perform reclamation. The properties of reclaimed oil sands...
A century of landscape change in the southern Rocky Mountains and Foothills of Alberta: Using historical photography to quantify ecological changeDownload
Throughout the Rocky Mountain regions of North America fire regimes have been altered towards longer fire return intervals in the 20th century as compared to the 18th and 19th centuries; this has been accompanied by losses of grassland and open canopy woodlands due to encroachment by closed...
The consideration of different spatial scales in ecological studies, including assessments of surrogacy, is often suggested, but less commonly implemented. Species utilize their environments at many spatial scales; therefore, the relationships between species including surrogate relationships,...
