Van Moorter, B., Mcloughlin, P. D., Gaillard, J. M., Duncan, P., Boyce, M. S., Delorme, D., Klein, F., Bonenfant, C., Messier, F., Said, S.
The relationship between individual performance and nonrandom use of habitat is fundamental to ecology; however, empirical tests of this relationship remain limited, especially for higher orders of selection like that of the home range. We quantified the association between lifetime reproductive...

Linking occurrence and fitness to persistence: habitat-based approach for endangered greater sage-grouse
Download2007
Detailed empirical models predicting both species occurrence and fitness across a landscape are necessary to understand processes related to population persistence. Failure to consider both occurrence and fitness may result in incorrect assessments of habitat importance leading to inappropriate...

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...

Planktonic and Epipelic Algal Communities and their Relationship to Physical and Chemical Variables in Alpine Ponds in Banff National Park, Canada
Download2005
McMaster, N. L., Schindler, D. W.
We surveyed 14 ponds in 1999 and 28 ponds in 2000 to better understand the basic limnology of alpine ponds and to predict how the planktonic and epipelic (sediment-living) algal communities may respond to nutrient deposition and climate change. Based on nitrogen to phosphorus ratios, nitrogen...

Belikov, S. E., Maslanik, J., Aars, J., Born, E. W., Amstrup, S. C., Serreze, M. C., Stirling, I., Wiig, O., Nielson, R. M., DeWeaver, E., Durner, G. M., Bailey, D. A., McDonald, T. L., Mauritzen, M., Holland, M. M., Derocher, A. E., Douglas, D. C.
Projections of polar bear (Ursus maritimus) sea ice habitat distribution in the polar basin during the 21st century were developed to understand the consequences of anticipated sea ice reductions on polar bear populations. We used location data from satellite-collared polar bears and...

Thiemann, G. W., Molnár, P. K., Derocher, A. E., Lewis, M. A.
Polar bear (Ursus maritimus) populations are predicted to be negatively affected by climate warming, but the timeframe and manner in which change to polar bear populations will occur remains unclear. Predictions incorporating climate change effects are necessary for proactive population...

Schneider, Richard R, Bayne, Erin M
Ecosystem distributions are expected to shift as a result of global warming, raising concerns about the long-term utility of reserve systems based on coarse-filter ecosystem representation. We tested the extent to which proportional ecosystem representation targets would be maintained under a...

Temperature-dependent Allee effects in a stage-structured model for Bythotrephes establishment
Download2011-01-01
Young, J. D., Yan, N. D., Lewis, Mark A., Wittmann, M. J.
Whether the invasive freshwater cladoceran Bythotrephes longimanus can establish after introduction into a water body depends on several biotic and abiotic factors. Among these, water temperature is important because both development rates and mode of reproduction (parthenogenetic or sexual) in...

Unusual predation attempts of polar bears on ringed seals in the southern beaufort sea: Possible significance of changing spring ice conditions
Download2008
Richardson, E., Stirling, I., Thiemann, G.W., Derocher, A.E.
In April and May 2003 through 2006, unusually rough and rafted sea ice extended for several tens of kilometres offshore in the southeastern Beaufort Sea from about Atkinson Point to the Alaska border. Hunting success of polar bears (Ursus maritimus) seeking seals was low despite extensive...
