Title of Project
Research Project Description
Climate warming is projected to alter species geographical distributions, as species track the climatic niche they have evolved to, moving upslope or to greater latitudes. Treelines, the ecotone where forests transition to non-forested ecosystems, are important systems as they occur at the edge of trees climatic tolerance. To date, there has been no clear global response of tree species to warming, suggesting that forest distribution may be limited by non-climatic factors.
My research is focused on identifying early-life stage bottlenecks to black spruce (Picea mariana) and tamarack larch (Larix laricina) altitudinal treeline recruitment, through experimental manipulation. I am particularly interested on identifying the role plant-plant interactions play, hoping to identify if inter and intraspecific interactions facilitate early germinant and seedling survival at treeline.
