Diatoms are planktonic algae whose siliceous skeletons are              commonly found in the marine and freshwater fossil record.                      Principal Investigator Eugene Stoermer proposes to continue his                 research into the evolutionary origins of freshwater diatoms, and               the ancestor-descendant relationships among living species of the               cymbelloid and gomphonemod diatoms.  Light and scanning electron                microscopy will be used to study ultrastructure, cytology and                   valve morphology.  Cladistic methods will be used to reconstruct                evolutionary relationships of living groups, which will then be                 compared with the sequence of their appearances in the fossil                   record.                                                                                 The proposed work has implications beyond the discipline of             diatom systematics.  Diatoms are widely used as environmental                   indicators in lakes, and the proposed work will improve their                   classification and identification criteria.  A better                           understanding of the tempo and mode of diatom evolution will                    emerge, and the project will serve as a model for other                         researchers attempting to do integrated research on modern and                  fossil species.
