Highlights:

  • As pollen is dispersed annually, it can be used as a natural climate proxy.
  • This research uses fossilized pollen from lake-bed sediment to
    • reconstruct decadal to centennial scale forest-vegetation dynamics and climate variability over the last thousand years and
    • investigate the effects of European colonization as well as anthropogenic climate change on sugar-maple hardwood forest ecosystems in southeastern Québec.
