Diatoms from an ice-wedge furrow, Ungava Peninsula, Quebec, Canada
AbstractThe first recorded information about living fresh water diatoms on an ice-wedge furrow is presented. One sample has been analysed and two species, Cymbella aequatis and Tabellaria flocculosa, formed almost half of the diatom population. Some rather rare species for the Canadian Eastern Arctic were identified: Fragilaria constricta, Eunotia lunaris, Eunotia microcephala, Pinnularia gibba, Anomoeoneis zellensis, and Cymbella aspea. Of the 37 species identified, most are common elsewhere in the Arctic.
