How we measure 'reads'
A 'read' is counted each time someone views a publication summary (such as the title, abstract, and list of authors), clicks on a figure, or views or downloads the full-text. Learn more
Currently pursuing a PhD degree in Biology. My project involves modelling agroforestry systems in Quebec and evaluating their contribution to the adaptation capacity of agroecosystems to climate change.
March 2012 - April 2012
- Stage interinstitutionnel
- Collaboration on the development of an agroforestry model (Hi-sAFe). Preparation of joint publication on the development, use and application of the Hi-sAFe model.
The study analyses the effects of two different forms of nitrogen fertilisation (nitrate and ammonium) on root structure and water uptake of two hybrid poplar (Populus maximowiczii x P. balsamifera) clones in a field experiment. Water uptake was studied using sap flow gauges on individual proximal roots and coarse root structure was examined by exc...
We evaluate the importance of changes in photosynthetic capacity, respiration rates, root shoot ratio, pipe model parameters and specific leaf area in the early-growth response of hybrid poplar to nitrogen availability. Juvenile growth simulations for trees with three different levels of leaf nitrogen concentration (Nleaf) (low (1.2%), medium (2.4%...
We compared prefire and postfire organic-layer depths in boreal forest types (14 fires) across Canada, and examined tree recruitment as a function of depth. There was extensive within-stand variation in depth, much of it due to clustering of thinner organic layers around boles. There were no significant differences in postfire organic-layer depth a...
