LATE-GLACIAL (ALLEROD) COLEOPTERA FROM JOGGINS, LANTZ AND BLOMIDON, CENTRAL NOVA-SCOTIA, CANADA

Three late-glacial sites in central Nova Scotia, Canada, have produced small Coleoptera assemblages that add to the palaeoenvironmental inte rpretation during the interval 11,800 to 10,800 years B.P. in the Mari times region. During this time, beetle assemblages are boreal in natur e, in contrast to older sites which contain tundra to tree-line specie s and later, Younger Dryas age sites, containing northern boreo-montan e species. Palaeoentomological interpretations from buried organic sit es near Joggins, Lantz and Blomidon are consistent with palynological results from the region and support evidence derived from lake sedimen ts for regional steep climatic gradients during the late-glacial perio d in the Maritimes.
