Tasmania has many polyhumic lakes with a wealth of phytoflagellates, especially chromophytes. Dystrophic coastal lagoons, such as Lake Garcia, are rich habitats of the Chrysophyta and Dinophyta, containing a number of new or rare species. In meromictic Lake Fidler and Sulphide Pool flagellates and prokaryotes are permanently zoned in a finely structured array astride the redoxcline. In the mixolimnetic waters phytoflagellates are zoned and probably perform regular migrations. Chaoborus larvae migrate daily. In monomictic, polyhumic Lake Chisholm there is probably a permanent zonation of flagellates and prokaryotes about the long-lasting thermocline, with diel migrations of other species in the epilimnion. With its numerous new or rare species Tasmania is a phytoflagellate haven. |
