Keyghobadi, N., Roland, J., Fownes, S.
We used mark-recapture methods to estimate the number of Parnssius smintheus (Papilionidae) butterflies moving among 20 alpine meadows separated by varying amounts of forest along the east slope of the Rocky Mountains in Alberta, Canada. We combined generalized additive models and generalized...

The boreal ecotype of woodland caribou (Rangifer tarandus caribou) is federally listed as Threatened due to population declines throughout its distribution. High mortality rates of neonate calves (≤ 4 weeks old) due to predation are a key demographic factor contributing to population declines...

The Rocky Mountain apollo butterfly, Parnassius smintheus, and its host-plant Sedum lanceolatum, are endemic to open alpine meadows threatened by the encroachment of trees. I explore variability in interactions between P. smintheus and S. lanceolatum relative to the treeline-delimited meadow...

Prevalence and predictability of handling effects on plants in field studies: Results from field experiments and a meta-analysis

Brown, M., Hik, D.S., Weir, J., Dabros, A., Cahill, J.F.
Various effects on plant growth associated with handling or touching plants are well documented from greenhouse and laboratory studies, but are generally unknown or ignored under field conditions. We examined the prevalence of the effects of handling, at levels typical of many ecological...

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...

Climate change is currently a central problem in ecology, with far-reaching effects on species that may be diffcult to quantify. Ectothermic species which rely on environmental cues to complete successive stages of their life history are especially sensitive to temperature changes and so are good...

The role of habitat quality and climate in the dynamics of occupancy and survival of a population of collared pikas (Ochotona collaris) in the Ruby Range, Yukon Territory
DownloadFall 2013
I examined the role of habitat quality and climate in the dynamics of occupancy and survival of a population of collared pikas in the Yukon Territory, Canada. Annual surveys of marked individuals over an 11 year period (1999 to 2009) within a geographically isolated metapopulation were used to...
