Protecting Agricultural Land: How Informal Institutions and Historical Perspectives Affect Land-Use Policy
DownloadFall 2022
Land-use pressures in Alberta's agricultural landscapes have intensified in recent years. With the province's broad historical agricultural base and ongoing urban expansion, there have been growing concerns about the loss of prime agricultural land. These concerns and conflicts have been...

THREE-DIMENSIONAL OUTCROP MODELLING, SEDIMENTOLOGY, AND ICHNOLOGY OF THE FALHER D MEMBER, NORTHEAST BRITISH COLUMBIA, CANADA
DownloadFall 2022
The Lower Cretaceous Falher Member is an important hydrocarbon reservoir in the Deep Basin of Alberta and British Columbia. Owing to its economic importance, it has been the subject of many studies. However, there remains contention on the depositional interpretation of individual Falher Member...

Precious metal, Lu-Hf, and Re-Os geochemistry of the metasomatized lithospheric mantle: implications for subcrustal precious metal mobilization and MARID petrogenesis
DownloadFall 2022
The connection between metasomatism - the change in chemical composition of a rock via interaction with a fluid or melt - and the formation of metalliferous ore deposits in the Earth’s crust is well established. Similarly, it is now accepted that the Earth’s lithospheric mantle has experienced...

Predation is an important process that helps to shape community structure. The study of predation in the fossil record has often used repair scars – traces of failed predatory attacks left on prey individuals – to identify differences in predation pressure across space, time, and taxa. However,...

Spatiotemporal variability of the fraction of Photosynthetically Active Radiation (fPAR) in a mixed coniferous forest using Wireless sensor networks
DownloadSpring 2022
Contemporary climate change has become rapid, and its impacts affect forest growth and productivity directly and indirectly through changes in temperature, precipitation, carbon dioxide, and other factors. Forest ecosystem plays an essential role in carbon exchange between the atmosphere and...

Water and Fine-grained Sediment Assessment in the Capital Region (Edmonton) of the North Saskatchewan River (Canada)
DownloadFall 2022
Purpose: To better understand the behaviors of sediment-associated metals (Cu, Ni, Cd, Mn, Cr, Pb, Fe, Sr, Mo, and Co), an evaluation of physicochemical parameters and metal speciation on suspended and bedload sediment collected from the North Saskatchewan River was conducted in 2018. Sampling...

River runoff plays a very important role in the Arctic Ocean. The Arctic Ocean accounts for around 1% of the total world ocean volume, but receives around 11% of the worlds river runoff. In addition, the Arctic Ocean is a β ocean, where stratification is primarily determined by salinity as...

Observations of Sun-Induced Chlorophyll fluorescence (SIF), Photochemical Reflectance Index (PRI) and Chlorophyll:Carotenoid Index (CCI) during spring recovery in two evergreen conifers from the Boreal Forest.
DownloadFall 2022
Northern hemisphere evergreen forests assimilate a significant fraction of global atmospheric CO2. Conifers undergo winter-downregulated photosynthetic activity and spring-onset photosynthetic activation. Currently, increased temperatures are leading to shifts in photosynthetic phenology (early...

In order to understand permafrost and paleoenvironmental conditions in the Mackenzie Delta Region, permafrost cores were collected in the winter of 2017, near the newly developed Inuvik-Tuktoyaktuk Highway (ITH), NWT, by the NWT Geological Survey, NWT Department of Infrastructure, the University...

Stable isotope development in ground ice along an alpine tundra slope in the Ogilvie Mountains, Yukon Territory
DownloadSpring 2022
Stable isotopic ratios of oxygen and hydrogen (δ18O and δD) from ground ice have been used to reconstruct paleoclimate temperatures spanning the Late Pleistocene and Holocene in subarctic and arctic regions. This is possible due to the strong relations between the isotopic composition of...
