Assessing Algal Community Structure and Nutrient Uptake Kinetics Across a Nutrient Gradient in Agricultural Streams
DownloadFall 2020
Streams provide important ecosystem services, such as the transformation of organic matter and water purification, while transporting water from headwaters to larger receiving waterbodies downstream. Excess nutrients introduced through anthropogenic land use put stress on aquatic ecosystems and...

Assessing Spatial and Temporal Variation in Source Water Quality and Drinking Water Treatability Across a Gradient of Forest Harvest on Vancouver Island, BC
DownloadFall 2021
On Canada’s Pacific Coast, forestry is integral to society. Although economically important, harvesting practices may alter source waters that originate in forested watersheds through changes in suspended solids (SS) and dissolved organic matter (DOM). Each of these metrics has the potential to...

Fall 2021
Streams provide essential ecosystem services including nutrient cycling and uptake, organic matter processing and ecosystem production and respiration. Stream ecosystem functioning provides an integrated metric of biological structures and processes that can respond to anthropogenic land use...

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...

Composition and Biodegradation of DOM Leached from Permafrost End-members across the Western Canadian Arctic
DownloadFall 2020
Organic matter, upon dissolution into the aqueous state as dissolved organic matter (DOM), can undergo mineralization by microbes (biodegradation). There has been increasing effort to characterize DOM released from thawing permafrost because it may perpetuate a permafrost carbon feedback....

Dissolved Organic Carbon Mobilization and Degradation Patterns in Retrogressive Thaw Slumps of the Peel Plateau, Northwest Territories, Canada
DownloadFall 2016
Anthropogenic climate change has affected the Canadian Arctic cryosphere, accelerating the development of retrogressive thaw slumps (RTS) across the Peel Plateau, NWT, Canada. RTS result from the thawing of ice-rich permafrost and develop due to ablation of ground ice exposed in the slump...

Elevation dependent landscape processes in rapidly warming sub-Arctic mountains: influences of snow, temperature and vegetation
DownloadFall 2015
The loss of spring snow in the Northern Hemisphere has been dramatic. From 1967 to 2008 snow cover decreased by 14% in May and 46% in June, with a simultaneous reduction in snow cover duration of 6 – 8 days per decade in both summer and fall. These effects have been particularly pronounced in...

Fall 2013
Subglacial bryophytes, entombed during the Little Ice Age (LIA, 150-580 years BP) beneath the polythermal Teardrop Glacier, Sverdrup Pass, Ellesmere Island, Nunavut, Canada, were examined. The diversity, paleoecological significance, and regeneration capacity of these bryophyte assemblages are...

Horns and hotspots: detecting change in mountain sheep populations over large spatiotemporal scales
DownloadSpring 2020
Long-term data is essential for addressing questions about how populations change over time in response to environmental variability, and natural and anthropogenic disturbance. Two species of mountain sheep (Ovis spp.) in Canada have been monitored over several decades and provided the data...

Icing dynamics in the lake-dominated, discontinuous permafrost Taiga Shield, and effects on fluvial biogeochemistry, carbon cycling and microbial communities
DownloadFall 2023
Climate warming is affecting freshwater systems across the western Canadian subarctic, due to widespread shifts in precipitation regimes, permafrost degradation, and multi-decadal increases in winter baseflow. These changes are significant on the Taiga Shield, which comprises ~20% of North...
