The Carleton University Paleoecological Laboratory (CUPL) was established in July 2002. Much of our research is carried out in regions of northwestern Canada, utilizing a variety of paleoecological indicators, including pollen, stomata, and charcoal preserved in lake-sediment and tree- ring growth records. By studying fossils preserved in lake- sediment we can study changes in vegetation, climate, and disturbance regimes over long temporal timescales, but at relatively low resolution. Tree-ring analysis, or dendrochronology, is used to study changing climatic conditions at annual resolution, but across shorter time scales.

Please take a moment and browse through our website and explore our on-going research projects. If you would like to learn more about the research activities of CUPL or are interested in graduate research, please contact Dr. Michael Pisaric ( We are always searching for promising new students interested in paleoecological research in the north!
