DOI: 10.1007/s00442-017-3914-4
Abstract: Phenological mismatch has been proposed as a key mechanism by which climate change can increase the severity of insect outbreaks. Spruce budworm (Choristoneura fumiferana) is a serious defoliator of North American conifers that feeds on… read more here.

DOI: 10.1016/j.agrformet.2016.11.005
Abstract: Abstract Old-growth (>100 years old) boreal forests are recognized as having accumulated large inventories of terrestrial carbon, but the magnitude of annual net exchange is not well established. Eddy covariance measurements of carbon dioxide exchange were… read more here.

DOI: 10.1016/j.conbuildmat.2017.03.028
Abstract: Abstract As a previous study has shown, it is possible to increase by 50% the dowel bearing strength of black spruce with an acrylate formulation applied by impregnation. Three diameters of bolts and two orientations… read more here.

DOI: 10.1016/j.ecolind.2018.09.059
Abstract: Abstract In managed boreal forests, partial harvesting has been proposed to promote forest structural complexity and to therefore maintain associated biodiversity. However, there have been few studies identifying forest structures that should be maintained within… read more here.

DOI: 10.1016/j.foreco.2017.06.029
Abstract: Abstract Drainage can help restore hydrological conditions conducive to the growth of black spruce (Picea mariana) seedlings on logged forested peatlands. The impact of drainage was assessed by analysing the variation in stand density at… read more here.

DOI: 10.1016/j.foreco.2017.09.068
Abstract: Abstract Recruitment of seed regenerating plants after disturbance depends on adequate seed supply and favourable microsites that allow germination and seedling establishment (safe sites). Forest disturbance in nutrient stressed conifer-ericaceous communities in boreal and temperate… read more here.
