A multi-scale test of the forage maturation hypothesis in a partially migratory ungulate population
Download2008
McDermid, G., Hebblewhite, M., Merrill, E.
The forage maturation hypothesis (FMH) proposes that ungulate migration is driven by selection for high forage quality. Because quality declines with plant maturation, but intake declines at low biomass, ungulates are predicted to select for intermediate forage biomass to maximize energy intake...

Divided landscapes: the emergence and dissipation of "The Great Divide" landscape narrative
DownloadFall 2011
Heights of land are, in a North American context, geographical boundaries—defined by the division of waters and a certain degree of elevation that sets them apart from the immediate environs. Heights of land are also landscaped places. Indeed, the hegemonic narrative that frames the height of...

Multiple carnivore species can have greater population limiting effects than single carnivores. Two coexisting carnivores can only be similar up to a certain extent. I investigate how two carnivores, wolves (Canis lupus) and cougars (Puma concolor), coexist through niche partitioning in the...

Abstract: Twenty topples are described from Rock Glacier Site, 2 km north of the summit of the Highwood Pass in the Front Ranges of the Rocky Mountains in Alberta. In situ field testing and laboratory tests indicated that the external force driving the toppling process is frost action within a...

Modelling long- term impacts of mountain pine beetle outbreaks on merchantable biomass, ecosystem carbon, albedo, and radiative forcing

Price, David T., Matthews, H. Damon, Parrott, Lael, Ramankutty, Navin, Landry, Jean-Sébastien
The ongoing major outbreak of mountain pine beetle (MPB) in forests of western North America has led to considerable research efforts. However, many questions remain unaddressed regarding its long-term impacts, especially when accounting for the range of possible responses from the non-target...

Whittington, J., Mercer, G., St. Clair, C.C.
Few studies have examined the effects of human development on fine-scale movement behavior, yet understanding animal movement through increasingly human-dominated landscapes is essential for the persistence of many wild populations, especially wary species. In mountainous areas, roads and trails...

Population Structure of Mountain Pine Beetle Symbiont Leptographium longiclavatum and the Implication on the Multipartite Beetle-Fungi Relationships
Download2014-01-01
Roe, Amanda D., Farfan, Lina, Cooke, Janice E. K., Hamelin, Richard C., El-Kassaby, Yousry A., Rice, Adrianne V., Tsui, Clement K.
Over 18 million ha of forests have been destroyed in the past decade in Canada by the mountain pine beetle (MPB) and its fungal symbionts. Understanding their population dynamics is critical to improving modeling of beetle epidemics and providing potential clues to predict population expansion....

Resilient Space: Bighorn Sheep (Ovis canadensis) Ecological Resilience in the Northern Rocky Mountains
DownloadFall 2016
Abstract Ecological resilience was defined, reviewed and discussed by synthesis of theory, concepts and empirical evidence presented in the primary literature (Chapter 1). Ecological resilience is concerned with ecological functions and the desirability of alternate states. Management and...

Runoff generation in a steep snow-dominated watershed in Alberta's southern Rocky Mountains
DownloadFall 2019
Star Creek is a snowmelt-dominated, steep mountain watershed with shallow soils, deep glacial till, and fractured sedimentary bedrock in the eastern slopes of Alberta’s Rocky Mountains. Measurements of streamflow quantity and chemistry at variable scales, water table dynamics, and precipitation...
