Deux carottes polliniques ont été prélevées dans la section nord du lac de la Hutte Sauvage. L’analyse pollinique révèle l’histoire de la végétation en quatre phases remontant à 4100 ans AA : 1 ) toundra herbeuse (4700 à 4100 ans AA); 2

Microfossils have been critical in unravelling the complex postglacial history of Georgian Bay. Thecamoebians (testate amoebae/rhizopods) record paleolimnological conditions, and pollen stratigraphy allows correlation across the basin, where sediment

Pollen analysis identified domestic Zea mays (corn, maize), Phaseolus vulgaris (kidney bean), Helianthus annuus (sunflower) and Cucurbita pepo (squash) accompanied by spores of fungi, many of which cause crop diseases, such as Ustilago maydis (=U. ze

The Fernbank interglacial site, on the west side of Cayuga Lake, New York, has been recently subjected to more detailed study. To a lengthened mollusc list are added ostracodes, insects, fish, pollen, and plant macrofossils. Of these, plants are well
