Abstract

Seventy five diatom species are identified in two sediment cores from Macquarie Harbour, Tasmania. Benthic taxa are overwhelmingly dominant, although peaks in the abundance of the planktonic Ditylum brightwellii could be traced across the area. Diatom assemblages are mostly homogeneous but assemblages from the most recent samples are clearly identifiable. Biodiversities before and after the impact of the Queenstown copper-lead-zinc mine were little different. The modern diatom assemblages, which have been affected by tailings sedimentation, are clearly differentiated from older, pre-mining assemblages. However, the differences are based on differing relative abundances of diatom species rather than different communities.
