Sequential decision-making in a variable environment: modeling elk movement in Yellowstone National Park as a dynamic game.
Download2007
Potapov, A. B., Noonburg, E. G., Newman, L. A., Lewis, M. A., Crabtree, R. L.
We develop a suite of models with varying complexity to predict elk movement behavior during the winter on the Northern Range of Yellowstone National Park (YNP). The models range from a simple representation of optimal patch choice to a dynamic game, and we show how the underlying theory in each...

Spatial Genetic Structure of a Symbiotic Beetle-Fungal System: Toward Multi-Taxa Integrated Landscape Genetics
Download2011
James, P.M.A., Hamelin, R.C., Murray, B.W., Coltman, D.W., Sperling, F.A.H.
Spatial patterns of genetic variation in interacting species can identify shared features that are important to gene flow and can elucidate co-evolutionary relationships. We assessed concordance in spatial genetic variation between the mountain pine beetle (Dendroctonus ponderosae) and one of its...

Mercer, G., St. Clair, C. C., Whittington, J.
Increasing levels of human activity in mountainous areas have high potential to inhibit animal movement across and among valleys. We examined how wolves respond to roads, trails, and other developments. We recorded the movements of two wolf packs for two winters by following their tracks in the...

Taking a Multispecies Approach to Evaluating the Effectiveness of Wildlife Passages for Small and Medium Sized Mammals in an Eastern Canadian Boreal Forest
Download2015-09-21
Descrochers, André, Jaeger, Jochen, Martinig, April Robin
Poster presented at the International Conference on Ecology and Transportation in 2015. Research is an investigation into the effectiveness of three different types of wildlife passages along Highway 175 in northern Quebec for small and medium sized mammals using infrared cameras. Two research...

The Aquatic Angiosperm Trapago angulata from the Upper Cretaceous (Maastrichtian) St. Mary River Formation of Southern Alberta.
Download1997
A floating aquatic dicot with leaves assignable to Trapago angulata has been characterized from Upper Cretaceous (Maastrichtian) deposits of the St. Mary River Formation in southern Alberta, Canada. Reconstruction of the plant is based on nearly 500 specimens of various isolated and attached...

The role of terrestrial vegetation in atmospheric Hg deposition: Pools and fluxes of spike and ambient Hg from the METAALICUS experiment
Download2012
Graydon, J.A., Harris, R., St. Louis, V., Sandilands, K.A., Rudd, J.W.M., Kelly, C.A., Richardson, M., Emmerton, C.A., Lindberg, S.E., Tate, M.T., Asmath, H., Krabbenhoft, D.P.
As part of the Mercury Experiment to Assess Atmospheric Loading in Canada and the U.S. (METAALICUS), different stable Hg(II) isotope spikes were applied to the upland and wetland areas of a boreal catchment between 2001 and 2006 to examine retention of newly deposited Hg(II). In the present...

Variation in premaxillary tooth count and a developmental abnormality in a tyrannosaurid dinosaur
Download2010
Tanke, D. H., Currie, P. J., Miyashita, T.
Premaxillary tooth count tends to be stable amongst toothed dinosaurs, and most theropods have four teeth in each premaxilla. Only one case of bilaterally asymmetric variation is known in theropod premaxillary dentition, and there is no record of ontogenetic or individual variation in...
