Botany, 2020 There is debate about what drives and maintains the structure of arboreal lichen communities and the relative importance of substrate vs. local environment.

Cellular phenology of annual ring formation of Abies balsamea in the Quebec boreal forest (Canada)
, 2003 Cell formation in growth rings of balsam fir (Abies balsamea (L.) Mill) in the boreal forest was studied to describe the timing of ring formation and the development patterns of earlywood and latewood.

The demographic cost of reproduction and its consequences in balsam fir (Abies balsamea)
The American Naturalist, 1999 It is an axiom of life-history theory that reproduction involves age-specific costs in terms of survival or future reproduction. The measurement of costs of reproduction in plants is difficult, and few field studies have measured these costs in terms of ...

Trees, 2009 There is general agreement that in many regions additional precipitation with climate change will not be able to balance the increased evaporation rate induced by higher air temperatures, causing periods of intense drought.

Pairing Spruce Budworm Control and Minimal Understory Perturbations: Effects of Btk Spraying Frequency in Boreal Forests. [PDF]
Ecol EvolSpruce budworm epidemic induces tree mortality and modifies understory communities. Could aerial spraying of Btk reduce perturbations in understory communities? Biannual Btk spraying could prevent both wood loss and understory degradation. ABSTRACT Since 1985, more than 10 million hectares of Canadian forests have been treated against spruce budworm ...

Will It Survive? Evaluating the Effects of Damage and Silviculture on Tree Seedling Survival Using Multi-State Models. [PDF]
Ecol EvolPlantations are the spearhead of adaptive silviculture, yet we do not understand how damage from abiotic and biotic agents relates to seedlings’ survival. In this study, we used multi‐state models, which originate from the medical field, to evaluate the relation between ‘damage history’, silvicultural treatments, and planted tree survival.

Springtime resumption of photosynthesis in balsam fir (Abies balsamea) [PDF]
Tree Physiology, 2008 Photosynthesis in balsam fir (Abies balsamea (L.) Mill.) was measured in the field at two locations in New Brunswick, Canada from late winter to late spring in 2004 and 2005. No photosynthesis was detectable while the soil remained below 0 degrees C throughout the rooting zone. In both years, photosynthesis began once soil temperature rose to 0 degrees

Carbon and biomass partitioning in balsam fir (Abies balsamea) [PDF]
Tree Physiology, 2005 Balsam fir (Abies balsamea (L.) Mill) was extensively sampled to investigate the effects of forest management practices, site location, within-crown position, tree component (i.e., stem, foliage, branches and roots), and tree social classes on biomass and carbon (C) partitioning at the individual tree level and across ecological regions. The sites were
