Large-scale insect outbreak homogenizes the spatial structure of ectomycorrhizal fungal communities
Download2019-01-01
Ectomycorrhizal fungi (plant symbionts) are diverse and exist within spatially variable communities that play fundamental roles in the functioning of terrestrial ecosystems. However, the underlying ecological mechanisms that maintain and regulate the spatial structuring of ectomycorrhizal fungal...

Characteristics of alpine plants and soils along an elevational gradient, Northern Selkirk Mountains, British Columbia
DownloadSpring 2019
Rates of climate change are accelerated at higher elevations, a pattern termed elevation-dependent warming (EDW). Consequently, the impacts of climate change on community patterning and soil development may be particularly evident in alpine environments. Alpine ecotone boundaries, such as...

Climate change will continue to affect the Arctic more intensely than other biomes. These changes can have dramatic effects on biotic interactions that influence the functioning of these systems, including plant-herbivore interactions. Invertebrate herbivores strongly depend on external...

A Functional Approach Reveals Zooplankton Responses to Environmental Change in Mountain Lakes
DownloadFall 2017
Concern is increasing over the future cumulative impacts of multiple stressors on freshwater biodiversity and ecosystem function, especially in alpine environments where climatic warming increases with elevation. Here, consideration of individual species traits enables translation of changes in...

Brachmann, Cole G., Hik, David S., Hernandez Ramirez, Guillermo
Data files used for analyses in manuscript titled "Soil development limits alpine plant establishment in recently-deglaciated terrain". The original data was collected in 2016/2017 and analyzed to be included in MSc. thesis titled "Characteristics of alpine plants and soils along an elevational...

Rebuilding the boreal: analyzing the replicability of the bacterial community structure and soil functioning of forest floor mineral mix with peat subsoil admixtures
DownloadSpring 2017
Alberta law requires reclamation of lands disturbed by surface mining operations, such as those occurring at the Athabasca Oil Sands Region, however, reclamation rates lag far behind continued disturbance rates. Due to cost, mining companies must make use of the materials on site, of which the...

After decades of recent fire exclusion in southern Alberta, Canada, forests are progressively aging and landscape mosaics are departing from their historical conditions. A large-scale fire history study spanning three natural subregions: Subalpine, Montane and Upper Foothills, was undertaken to...

Reclamation of northern disturbances is of increasing importance as industrial activities and associated infrastructure expands to accommodate growing human reliance on world ecosystems. Bryophytes are recognized as ecologically essential to northern ecosystems and effectively promoting their...

Limited impacts of extensive human land use on dominance, specialization, and biotic homogenization in boreal plant communities
Download2015-01-01
Mayor, S. J., Boutin, S., He, F., Cahill, J. F.
Background Niche theory predicts that human disturbance should influence the assembly of communities, favouring functionally homogeneous communities dominated by few but widespread generalists. The decline and loss of specialists leaves communities with species that are functionally more similar....

Scaling Disturbance Instead of Richness to Better Understand Anthropogenic Impacts on Biodiversity
Download2015-01-01
Mayor, S. J., Cahill, J. F., He, F., Boutin, S.
A primary impediment to understanding how species diversity and anthropogenic disturbance are related is that both diversity and disturbance can depend on the scales at which they are sampled. While the scale dependence of diversity estimation has received substantial attention, the scale...
