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...

Climate change could alter the distribution of mountain pine beetle outbreaks in western Canada

Sambaraju, Kishan R., Carroll, Allan L., Zhu, Jun, Stahl, Kerstin, Moore, R. Dan, Aukema, Brian H.
Climate change can markedly impact biology, population ecology, and spatial patterns of eruptive insects due to the direct influence of temperature on insect development and population success. The mountain pine beetle Dendroctonus ponderosae (Coleoptera: Curculionidae), is a landscape-altering...

Disentangling detoxification: Gene expression analysis of feeding mountain pine beetle illuminates molecular-level host chemical defense detoxification mechanisms
Download2013-01-01
Bohlmann, Jörg, Bonnett, Tiffany R., Pitt, Caitlin, Keeling, Christopher I., Yuen, Macaire M. S., Huber, Dezene P. W., Robert, Jeanne A.
The mountain pine beetle, Dendroctonus ponderosae, is a native species of bark beetle (Coleoptera: Curculionidae) that caused unprecedented damage to the pine forests of British Columbia and other parts of western North America and is currently expanding its range into the boreal forests of...

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...

Effect of age of the intermediate host Tribolium confusum (Coleoptera) on infection by Hymenolepis diminuta (Cestoda).
Download2008
A cross-sectional study of 27 cohorts of Tribolium confusum aged 2–78 wk was done to examine effects of host age on exposure to eggs of Hymenolepis diminuta under standardized conditions. Pre-exposure, fasting, and postexposure mortality were low, sex ratio was equal, and fecundity of hosts was...

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...
