Moth Diversity in a Fragmented Habitat: Importance of Functional Groups and Landscape Scale in the Boreal Forest
Download2006
Abstract: One of the leading concerns for both conservation biology and forestry has been bow forest fragmentation affects biodiversity, and how forestry practices can be altered to mitigate diversity losses. However, the effects of habitat fragmentation on ecological functional groups within...

Movement Patterns of Adult Male Ovenbirds during the Post-Fledging Period in Fragmented and Forested Boreal Landscapes
Download2001
Bayne, Erin M., Hobson, Keith A.
Movement of forest songbirds among isolated forest patches following breeding represents an important but poorly understood component of landscape ecology and metapopulation theory. Using radio-telemetry, we followed 44 male Ovenbirds (Seiurus aurocapillus) during the post-fledging period to...

Optimal forest harvest age considering carbon sequestration in multiple carbon pools: A comparative statics analysis
Download2012
Armstrong, Glen W, Asante, Patrick
We present an analytical model for determination of the economically optimal harvest age of a forest stand considering timber value, and the value of carbon fluxes in living biomass, dead organic matter, and wood products pools. Through comparative statics analysis, we find that consideration of...

Prevalence and predictability of handling effects on plants in field studies: Results from field experiments and a meta-analysis
Download2003-01-01
Brown, M., Hik, D.S., Weir, J., Dabros, A., Cahill, J.F.
Various effects on plant growth associated with handling or touching plants are well documented from greenhouse and laboratory studies, but are generally unknown or ignored under field conditions. We examined the prevalence of the effects of handling, at levels typical of many ecological...

Responses of black spruce (Picea mariana) and tamarack (Larix laricina) to flooding and ethylene treatments.
Download2003
Zwiazek, J.J., Macdonald, S. Ellen, Islam, M. Anisul
Black spruce (Picea mariana (Mill.) BSP) and tamarack (Larix laricina (Du Roi) K. Koch) are the predominant tree species in the boreal peatlands of Alberta, Canada, where low nutrient availability, low soil temperature and a high water table limit their growth. Effects of flooding for 28 days on...

Salvage logging, edge effects and carabid beetles: connections to conservation and sustainable forest management
Download2006
Cobb, T.P., Brigham, R.M., Philips, I.D., Spence, J.R.
We used pitfall traps to study the effects of fire and salvage logging on distribution of carabid beetles over a forest disturbance gradient ranging from salvaged (naturally burned and subsequently harvested) to unsalvaged (naturally burned and left standing). Significantly more carabids were...

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...

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...

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...

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...
