A multiproxy study of a sediment sequence from a Québec peatbog characterises the rapid and significant environmental responses to changing climatic conditions from the deglaciation of the Laurentide Ice Sheet to the early Holocene period. Scotstown Bog (45°30'45.0“N, 71°11'42.0“W) is an ombrotrophic peatland on the edge of the Appalachian Uplands in southern Québec, Canada. We reconstructed its Late‐glacial and early Holocene...

Aim Using a new approach to analyse fossil pollen data, we investigate temporal and spatial patterns in Populus ( poplar, cottonwood, aspen) from the Late Glacial to the present at regional to continental scales. Location North America. Methods We extracted data on the timing and magnitude of the maximum value of Populus pollen from each pollen diagram in the North American Pollen Database (NAPD). The information was plotted i...
