Harden, J.W., Payne, N., Friedli, H.R., Radke, L.F., Crock, J., Flannigan, M.D., Turetsky, M.R.
With climate change rapidly affecting northern forests and wetlands, mercury reserves once protected in cold, wet soils are being exposed to burning, likely triggering large releases of mercury to the atmosphere. We quantify organic soil mercury stocks and burn areas across western, boreal Canada...

Unusual predation attempts of polar bears on ringed seals in the southern beaufort sea: Possible significance of changing spring ice conditions
Download2008
Richardson, E., Stirling, I., Thiemann, G.W., Derocher, A.E.
In April and May 2003 through 2006, unusually rough and rafted sea ice extended for several tens of kilometres offshore in the southeastern Beaufort Sea from about Atkinson Point to the Alaska border. Hunting success of polar bears (Ursus maritimus) seeking seals was low despite extensive...

Trembling aspen seedling establishment, growth and response to fertilization on contrasting soils used in oil sands reclamation.
Download2012
Landhäusser, S. M., Chow, P. S., MacKenzie, M. D., Pinno, B. D., Quideau, S. A.
Trembling aspen (Populus tremuloides) is an important tree species for land reclamation. This study determined trembling aspen germination, establishment, initial growth and response to fertilizer on contrasting oil sands reclamation soils. In a greenhouse, eight soils varying in total nitrogen...

Toward conservation of Canada's boreal forest avifauna: Design and application of ecological models at continental extents
Download2010
Cumming, S. G., Bayne, E., Schmiegelow, F. K. A., Fontaine, T., Song, S. J., Lefevre, K.
Abstract: Human development is increasing pressure on North America's mainly intact boreal forest. We outline the need for a comprehensive synthesis of existing data and for effective scientific tools to support conservation of this biome and of the birds that depend on it. To illustrate how...

The role of historical fire disturbance in the carbon dynamics of the pan-boreal region: A process-based analysis
Download2007
Apps, M., Zhuang, Q., Burnside, T.J., Shvidenko, A., Flannigan, M., McAllister, J., Wirth, C., Clein, J.S., Balshi, M.S., Kurz, W.A., Kicklighter, D.W., Harden, J., McGuire, A.D., Kasischke, E., Melillo, J.
Wildfire is a common occurrence in ecosystems of northern high latitudes, and changes in the fire regime of this region have consequences for carbon feedbacks to the climate system. To improve our understanding of how wildfire influences carbon dynamics of this region, we used the process-based...

Purdy, B. G., Dale, M. R. T., MacDonald, S. E.
Abstract: Early establishment of white spruce (Picea glauca) in mixedwood boreal forest stands following fire was examined at several times-since-fire (1-, 2-, 4-, 6-, 14-years). Abiotic and biotic conditions in the stands were assessed at two scales, tree plot (5 in x 5 in) and microsite (1 m x...

Temporal variability in area burned for the Province of Ontario, Canada during the past 200 years inferred from tree-rings
Download2006
Tardif, J., Flannigan, M.D., Girardin, M.P.
Area burned variability in the province of Ontario, Canada, was inferred from 25 tree ring width chronologies covering A. D. 1781-1982 and distributed largely across the Boreal Shield. The area burned estimates account for 39.5% of the variance in the actual area burned recorded from 1917 to 1981...

Temperature-dependent Allee effects in a stage-structured model for Bythotrephes establishment
Download2011-01-01
Young, J. D., Yan, N. D., Lewis, Mark A., Wittmann, M. J.
Whether the invasive freshwater cladoceran Bythotrephes longimanus can establish after introduction into a water body depends on several biotic and abiotic factors. Among these, water temperature is important because both development rates and mode of reproduction (parthenogenetic or sexual) in...

Structure and composition of riparian boreal forest: new methods for analyzing edge influence
Download2001
Abstract: Riparian ecotones at lakeshore edges are prominent features on the heterogeneous boreal forest landscape. We introduce a new method (the critical values approach): which incorporates inherent variability in interior forest, to quantify distance of edge influence at lakeshore forest...
