Thesis title: Methods of reconstructing historical and contemporary atmospheric deposition using various components of bog ecosystems form contemporary collections and herbarium material
Ombrotrophic bogs are excellent records of atmospheric deposition as they receive all mineral inputs from the air through atmospheric deposition. In biomonitoring applications, several components of bog ecosystems have been used to reconstruct atmospheric deposition however, each of these components has various strengths and weaknesses. We hope to show how these measurements can be improved by measuring several biological components of a bog and aggregating them in a suitable manner. We will also explore how best to combine these results to most accurately recreate atmospheric deposition. We will apply these lessons learned in contemporary samples to herbarium samples in an attempt to recreate historic deposition in extremely high resolution.
I received a BSc from the University of Alberta and later went on to complete my Masters of Forestry at the same institution. I also have 5 years of consulting experience working in boreal ecosystems as an environmental scientist. My professional and academic career have been heavily focused on peatlands, their restoration and conservation and mosses, their biology, conservation and uses. Beyond my work, you’re more likely to find me in the middle of a forest or in my garden than spending time indoors.
