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...

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...

Effects of Habitat Fragmentation on Pairing Success of Ovenbirds: Importance of Male Age and Floater Behavior
Download2001
Bayne, Erin M., Hobson, Keith A.
Between 1996 and 1998, we compared pairing success of territorial male Ovenbirds (Seiurus aurocapillus) in forest fragments created by forestry (n 5 3) and agriculture (n 5 10) to contiguous forest plots (n 5 3) in the southern boreal mixedwood forest of central Saskatchewan. The percentage of...

Several studies have documented elevated rates of nest predation for passerines and grouse in small forest patches and near anthropogenic edges. We examined patterns of predation on artificial nests in aspen (Populust remuloidesw) oodlots and fencerows surrounded by agricultural land in Alberta....

The critical domain size problem determines the size of the region of habitat needed to ensure population persistence. In this paper we address the critical domain size problem for seasonally fluctuating stream environments and determine how large a reach of suitable stream habitat is needed to...

Wilson, W.F., Lingle, S., Feldman, A., Boyce, M.S.
Variation in the temporal pattern of vulnerability can provide important insights into predator-prey relationships and the evolution of antipredator behavior. We illustrate these points with a system that has coyotes (Canis latrans) as a predator and two species of congeneric deer (Odocoileus...

Interannual variability in trophic status of shallow lakes on the boreal Plain: Is there a climate signal?
Download2008
Devito, K.J., Bayley, S.E., Creed, I.F., Sass, G.Z.
We explored relations between climate and trophic status of shallow lakes (lake area > 5 ha, mean depth < 3.2 m) located on the subhumid western Boreal Plain of Canada. Correlation and regression analyses were used to assess the association between indicators of climate and satellite-based...
