Abstract
Modern pollen assemblages from lakes in the Canadian high-arctic and middle-arctic vegetation zones are used to document geographic differences in pollen deposition. There are differences in the pollen percentages of the herbaceous taxa that can be used to discriminate the various regions of the Arctic. High-arctic pollen assemblages have higher Poaceae, while middle-arctic sediments have higher Cyperaceae percentages. Pollen spectra from Banks Island contain higher percentages of Saxifragaceae, Brassicaceae, and Tubuliflorae, while lake sediments from the central Arctic contain more Ranunculaceae and Caryophyllaceae pollen. Salix and Oxyria pollen percentages are relatively high in samples from Ellesmere Island. Pollen from the low-arctic and boreal zones can comprise a significant component of the assemblages in arctic sediments, and this is more important in the southern islands of the Canadian Arctic Archipelago.
