Abstract

Three late-glacial sites in central Nova Scotia, Canada, have produced small Coleoptera assemblages that add to the palaeoenvironmental interpretation during the interval 11,800 to 10,800 years B.P. in the Maritimes region. During this time, beetle assemblages are boreal in nature, in contrast to older sites which contain tundra to tree-line species and later, Younger Dryas age sites, containing northern boreo-montane species. Palaeoentomological interpretations from buried organic sites near Joggins, Lantz and Blomidon are consistent with palynological results from the region and support evidence derived from lake sediments for regional steep climatic gradients during the late-glacial period in the Maritimes. RÉSUMÉ Trois emplacements tardiglaciaires du centre de la Nouvelle-Écosse, au Canada, ont produit des assemblages de petits coléoptères qui ajoutent à l’interprétation du contexte paléoenvironnemental existant pendant l'intervalle de 11 800 à 10 800 ans BP dans la région des Maritimes. Au cours de cette période, les assemblages de coléoptères présents étaient de nature boréale, par contraste avec les emplacements plus anciens abritant des végétaux variant de la toundra à la limite de végétation des arbres, ainsi qu'avec les sites plus regents de l'époque des dryades ultérieurs renfermant des espèces boréales subalpines septentrionales. Les interprétations paléoentomologiques des emplacements organiques enfouis près de Joggins, Lantz et Blomidon correspondent aux constatations palynologiques de la région et appuient les indications tirées des sédiments lacustres témoignant de gradients climatiques régionaux élevés pendant la période tardiglaciaire dans les Maritimes.
