Abstract

A sequence of sediments spanning the period from about 16,000 to 10,200 years B.P. from the Queen Charlotte Islands on the Pacific Coast of Canada was examined for fossil Cladocera. The basal sediments (about 16,000 B.P.) represent a late glacial to post-glacial sequence containing a very depauperate cladoceran and aquatic plant community. With greater development of submersed aquatic macrophytes (11,850-13,000 B.P.), cladoceran species diversity increased markedly. During maximal development of submersed and emergent aquatics (10,700-11,100 B.P.), 12 to 15 species of chydorid Cladocera occurred. A peat bog gradually formed, populated by more acid-tolerant chydorid species.
