img_0979My PhD project aims to improve our understanding of the acclimation capacity of photosynthesis and respiration to climate change, focusing on regions, such as high latitudes and the tropics, where we lack data.

I’m studying how combined increases of temperature (up to a 9 °C warming) and CO2 (up to 900 ppm) affect carbon fluxes in two dominant boreal conifer tree species, Picea mariana (black spruce, an evergreen tree) and Larix laricina (tamarack, a deciduous conifer). My work tackles this question in two ways, by 1) using seedlings grown in greenhouses in the UWO Biotron Centre for Climate Change (http://uwo.ca/sci/research/biotron/), where I’m also measuring growth; and 2) using mature trees (> 40 years old) at the SPRUCE experiment in the Marcel Experimental Forest, Minnesota, USA (http://mnspruce.ornl.gov/project/site-description). In addition, my project will explore the thermal acclimation capacity of photosynthesis and respiration in tropical montane rainforest tree seedlings, taking advantage of an elevational gradient in Rwanda. This work will provide urgently needed data for modelers to improve the accuracy of future climate-vegetation feedbacks in biomes where these responses are most uncertain.
