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...

Influence of subhumid climate and water table depth on groundwater recharge in shallow outwash aquifers
Download2008
Smerdon, B.D., Mendoza, C.A., Devito, K.J.
[1] Hypothetical one-dimensional models of unsaturated flow were used to estimate the probability of groundwater recharge to shallow, glacial outwash aquifers. Simulations were supported by field data, previous three-dimensional modeling, and cross-sectional models of water table response to...

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...

Evaluating wildlife passage use and discovery for small and medium sized mammals in an Eastern Canadian boreal forest
Download2015-08-14
Martinig, April Robin, Desrochers, André , Jaeger, Jochen
Paper presented at the 100th Annual Meeting of the Ecological Society of America in 2015. BACKGROUND/QUESTION/METHODS: While many studies have looked at how large mammals respond to road mitigation measures, few studies have examined the effects on smaller mammals or taken a multispecies...

Effects of forest harvesting and fire on fish assemblages in Boreal Plains lakes: A reference condition approach
Download2003
Scrimgeour, G.J., Lange, M., Prepas, E.E., Westcott, K., Aku, P.K.M., Paszkowski, C.A., Tonn, W.M.
To assess the impacts of forest harvesting and fires on lentic fish assemblages in the Boreal Plains ecoregion (Alberta, Canada), we applied a reference condition approach to 37 lakes in burned, logged, or undisturbed catchments. Fish assemblages in the reference lakes were classified into two...

While many studies have evaluated wildlife passage effectiveness, few have explored how accurately passage activity can be modelled. I created a habitat suitability index (HSI) model for American mink (Neovison vison) using Geographic Information Systems with 17 wildlife passages located in Quebe...

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...

A multi-scale test of the forage maturation hypothesis in a partially migratory ungulate population
Download2008
McDermid, G., Hebblewhite, M., Merrill, E.
The forage maturation hypothesis (FMH) proposes that ungulate migration is driven by selection for high forage quality. Because quality declines with plant maturation, but intake declines at low biomass, ungulates are predicted to select for intermediate forage biomass to maximize energy intake...
