Are Point Counts of Boreal Songbirds Reliable Proxies for More Intensive Abundance Estimators?
Download2006
Villard, M.-A., Schmiegelow, F.K.A., Hannon, S.J., Toms, J.D.
Point counts are often used to provide information on abundance of songbirds. If data from point counts are to be compared in space or time, however, any bias in the estimate should be consistent and linearly related to the true abundance. Several studies have suggested that this assumption may...

Assessing operational silviculture and modeling juvenile growth in Saskatchewan white spruce (Picea glauca (Moench) Voss) plantations
DownloadFall 2015
White spruce (Picea glauca (Moench) Voss) plantations are often established with mechanical site preparation and tending. These silvicultural treatments encourage plantation survival and can influence growth, composition, and yield. To assess operational silviculture and model managed stand...

Assessing the relationships between weather, food limitation and breeding ecology in an Arctic top predator
DownloadSpring 2016
A long term project being conducted on a population of Peregrine Falcons (Falco peregrinus) breeding near Rankin Inlet, Nunavut, Canada, has chronicled a steady decline in annual productivity over 30 years. By documenting the direct effects of summer rainfall on nestling mortality, a recent study...

Biological and environmental correlates of cougar (Puma concolor) survival in west central Alberta
DownloadSpring 2023
Large carnivores have a significant role in ecosystems and their role as apex predators can have cascading effects that influence ecosystem stability. Managing large carnivores requires an understanding of how they use the land and their vital rates, including survival. For cougars (Puma...

Wein, R.W., Cumming, S.G., Flannigan, M.D., Krawchuk, M.A.
Lighting, fire is the dominant natural disturbance of the western mixedwood boreal forest of North America. We quantified the independent effects of weather and forest composition oil lightning fire initiation (a detected and recorded fire start) patterns in Alberta, Canada, to demonstrate how...

Boreal trees can grow on saline sites – implications for reclamation success on saline soils
Download2015-03-04
Soils from oil sands mining can be affected by salts leached from tailings or overburden materials – resulting in saline soil conditions. As a result, re-establishment of forests on saline sites is an important goal on reclaimed oil sands mines. Forest vegetation is typically thought to be...

Breeding Bird Communities in Boreal Forest of Western Canada: Consequences of "Unmixing" the Mixedwoods
Download2000
Silvicultural practices following clearcutting in boreal forest may encourage the creation of monospecific, single-aged stands having less vegetation heterogeneity and diversity than original stands. We conducted point counts in central Saskatchewan, Canada, 1993–1995, in pure and mixedwood...

Chemical similarity between historical and novel host plants promotes range and host expansion of the mountain pine beetle in a naïve host ecosystem
Download2013-01-01
Evenden, Maya, Shan, Bin, Ma, Cary, Najar, Ahmed, Erbilgin, Nadir, Whitehouse, Caroline
Host plant secondary chemistry can have cascading impacts on host and range expansion of herbivorous insect populations. We investigated the role of host secondary compounds on pheromone production by themountain pine beetle (Dendroctonus ponderosae) (MPB) and beetle attraction in response to a...
