Coupling mountain pine beetle and forest population dynamics predicts transient outbreaks that are likely to increase in number with climate change
Download2023-09-27
Mountain pine beetle (MPB) in Canada have spread well beyond their historical range. Accurate modelling of the long-term dynamics of MPB is critical for assessing the risk of further expansion and informing management strategies, particularly in the context of climate change and variable forest...

Beautifully preserved, nearly complete theropod skeletons from Alberta (Canada) allow re-evaluation of the taxonomic status of North American tyrannosaurids. It is concluded that the most parsimonious interpretation of relationships leads to the separation of the two species of Albertosaurus...

Disruption of a belowground mutualism alters interactions between plants and their floral visitors
Download2008-01-01
Cahill, J. F., Shore, B. H., Smith, G. R., Elle, E.
Plants engage in diverse and intimate interactions with unrelated taxa. For example, aboveground. oral visitors provide pollination services, while belowground arbuscular mycorrhizal fungi (AMF) enhance nutrient capture. Traditionally in ecology, these processes were studied in isolation,...

Williams, B. W., Williams, K. L., Gelder, S. R., Proctor, H. C.
ABSTRACT.—Northern crayfish, Orconectes virilis (Hagen, 1870), were collected from 89 sites across Alberta, Saskatchewan, Manitoba, Montana, North Dakota, and Minnesota. The entocytherid ostracod Thermastrocythere riojai (Hoff, 1943) was found on O. virilis at 45 of the 89 sites, distributed...

Effects of aspen harvesting on groundwater recharge and water table dynamics in a subhumid climate
Download2011
Devito, K.J., Mendoza, C.A., Smerdon, B.D., Carrera-Hernández, J. J., Petrone, R.M.
Numerical experiments were developed using different water table depths and soil textures to investigate the impact of aspen harvesting on hydrological processes on the Western Boreal Plain. The effect of harvesting on soil moisture dynamics, fluxes at the water table, and water table fluctuation...

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...

McLachlan, J. S., Lewis, M. A., HilleRisLambers, J., Clark, J. S.
Recent literature on plant population spread advocates quantification of long-distance dispersal (LDD). These estimates could provide insights into rates of migration in response to climate change and rates of alien invasions. LDD information is not available for parameterization of current...

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...

Small-scale vertical aerial photographs taken in 1947 and 1948 covering 200 km2 of the Kluane Ranges, southwest Yukon, were compared with corresponding photographs taken in 1989 for the purpose of characterizing changes in the distribution and abundance of white spruce (Picea glauca (Moench)...

The goal of this guide is to derive a better understanding of the biodiversity of sponges across the eastern Canadian Arctic. Specimens were collected during research cruises aboard the Canadian Coast Guard Ship (CCGS) Amundsen in October 2015, July 2016 and July 2017. Collection sites were...
