“…Thus the degrees of mixolimnetic mixing and entrainment of tychoplankton will be different, with influences on species composition as reported by Bland & Brook (1974). On this point, the Triglochin beds at the edges of Sulphide Pool are festooned with clouds of filamentous algae, harbouring desmids in the manner reported by Brook (1981) and Bland & Brook (1974). The reasons for the greater number of chrysophytes in Lake Fidler compared with Sulphide Pool is not clear.…”

A floristic list of 89 freshwater phytoplanktonic algae occurring in two neighbouring, dystrophic, meromictic Tasmanian lakes is given. In both lakes the preponderance of desmids and phytoflagellates, especially chrysophytes, is a characteristic in keeping with their dystrophic nature. All the alga must be adapted to low levels of red light and some habitually inhabit crepuscular depths rather than executing die1 vertical migrations such as happens in many dystrophic waters. Floristic differences between the two lakes are related to morphometric differences and the degree of entrainment of tychoplankton. The photosynthetic biomass of both lakes is predominantly monimolimnetic, made up of few species. The floristically-rich mixolimnion contributes little to biomass. The ecology of the dystrophic flora is discussed in relation to the special circumstances of meromixis.introduction
