Searching allows animals to find food, mates, shelter and other resources essential for survival and reproduction and is thus among the most important activities performed by animals. Theory predicts that animals will use random search strategies in highly variable and unpredictable environments....

Examining the impact of climate change on snowshoe hare demography and community interactions in the northern boreal forest
DownloadSpring 2020
Ecologists are under increasing pressure to predict the influence of climate change on species demography along with the broader impacts on community and ecosystem structure. Predicting community responses to climate change, however, is a formidable challenge, that can be ameliorated by...

The persistence of forest-dependent species in fragmented landscapes is fundamentally linked to the movement of individuals among subpopulations. The paths taken by dispersing individuals can be considered a series of steps built from individual route choices. Despite the importance of these...

For some salmon populations, the individual and population effects of sea lice (Lepeophtheirus salmonis) transmission from sea cage salmon farms is probably mediated by predation, which is a primary natural source of mortality of juvenile salmon. We examined how sea lice infestation affects...

Crabtree, R., Lewis, M. A., Moorcroft, P. R.
The traditional models used to characterize animal home ranges have no mechanistic basis underlying their descriptions of space use, and as a result, the analysis of animal home ranges has primarily been a descriptive endeavor. In this paper, we characterize coyote (Canis latrans) home range...

Interactions between the forest tent caterpillar (Malacosoma disstria Hubner) and its natural enemies: the effects of forest composition and implications for outbreak spread
DownloadFall 2011
Forest tent caterpillar (Malacosoma disstria Hübner; FTC), a major defoliator of aspen trees, occupies both aspen and mixedwood forest stands in Alberta’s boreal forest. Forest stand composition could influence the spatial pattern of FTC outbreaks if mortality from natural enemies differs...

Interactions between the mountain pine beetle (Dendroctonus ponderosae Hopkins) and whitebark pine (Pinus albicaulis Engelmann)
DownloadSpring 2012
I compared life history traits between mountain pine beetles (MPB) utilizing whitebark pine and lodgepole pine to better understand how host use could affect MPB impact in the Rocky Mountains of Alberta, Canada. Neither host was obviously better in terms of quality for or susceptibility to the...

Local and regional demography in a migratory forest songbird and effects of forest management intensity
DownloadSpring 2014
The numerical response of forest birds to habitat alteration has been well documented in North America, but the underlying demographic processes driving these changes remain largely unknown. Among species sensitive to such alterations, the Ovenbird (Seiurus aurocapilla) shows one of the largest...

Movement ecology thrives from a successful synergy of data and models. In a field where experiments are difficult or impossible, linking field data with mathematical and statistical models allows us to test hypotheses and increase our quantitative understanding of movement processes. Owing to...
