North Saskatchewan Watershed Alliance (NSWA)
The North Saskatchewan River Basin (NSRB) exhibits significant spatial variability in temperature and precipitation, both within any given year and from year to year. In the mountains and higher foothills, precipitation tends to be relatively high and evapotranspiration low, resulting in high...

Water Trading: Irrigation Technology Adoption and Economic Impact of Transboundary Water Reallocation
DownloadFall 2014
The overall purpose of the study is to evaluate how water trading could improve water use efficiency in southern Alberta, Canada and how benefits of water reallocation could be achieved in the Nile River basin in Africa. The impact of water scarcity has become more prominent in these areas in...

Two structure-function hypotheses were tested for vesselless angiosperm wood. First, vesselless angiosperm wood should have much higher flow resistance than conifer wood because angiosperm tracheids lack low-resistance torus-margo pits. Second, vesselless wood ought to be exceptionally safe from...

Water-deficit and fungal infection can differentially affect the production of different classes of defense compounds in two host pines of mountain pine beetle

Erbilgin, Nadir, Cale, Jonathan, Lusebrink, Inka, Najar, Ahmed, Klutsch, Jennifer, Sherwood, Patrick, Bonello, Pierluigi, Evenden, Maya
Bark beetles are important agents of tree mortality in conifer forests and their interaction with trees is influenced by host defense chemicals, such as monoterpenes and phenolics. Since mountain pine beetle (Dendroctonus ponderosae Hopkins) has expanded its host range from lodgepole pine (Pinus...
