    Phyloflagellates and their ecology in Tasmanian polyhumic lakes (1988)
    Springer
    Hydrobiologia 161 (1988), S. 245-253 
    Details
    ISSN: 1573-5117
    Keywords: Phytoflagellates ; diel migration ; zonation ; polyhumic ; meromictic ; bacteria ; Chaoborus ; Chrysophyta ; Dinophyta

    Topics: Biology
    Notes: Abstract 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.

    Morphology and taxonomy of Cyclotella tasmanica spec. nov, a newly described diatom from Tasmanian lakes (1993)
    Springer
    Hydrobiologia 269-270 (1993), S. 49-56 
    Details
    ISSN: 1573-5117
    Keywords: taxonomy ; morphology ; Cyclotella ; lakes ; Tasmania
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology
    Notes: Abstract A species of Cyclotella with an elliptical valve outline has been found in several Tasmanian lakes and is herein described and named C. tasmanica nov. sp. Morphologically, it is similar to C. stelligera and, to a lesser extent, to C. radiosa. The valve has coarse, clearly alveolate, marginal striae and a central rosette. Unlike other elliptical forms, the central area is always more or less circular. The nearest similar species is C. rhomboideo-elliptica.

    Water chemistry of the River Kwai, Thailand (1984)
    Springer
    Hydrobiologia 111 (1984), S. 65-73 
    Details
    ISSN: 1573-5117
    Keywords: water chemistry ; River Kwai ; Asia
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology
    Notes: Abstract The water chemistry of the River Kwai Noi, its tributaries, and the neighbouring Kwai Yai is shown to be dominated heavily by calcium bicarbonate. Water arriving as rain from the sea to the west readily picks up the alkaline earth bicarbonate from the abundant limestone in the catchment. The river is turbid but well oxygenated. It will soon be impounded by a new dam, the Khao Laem project.

    Primary productivity and trophic status of Lakes Sorell and Crescent, Tasmania (1976)
    Springer
    Hydrobiologia 48 (1976), S. 59-64 
    Details
    ISSN: 1573-5117
    Keywords: Primary production ; Trophic state ; Tasmanian lakes
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology
    Notes: Abstract The primary productivity of two turbid, shallow lakes on the Tasmanian Central Plateau was determined by the C14 technique from half-light day incubations in situ. Graphical integration of depth-rate curves gave estimates of areal day rates of production and of annual rates. The 2 lakes are closely adjacent and very similar physically and chemically, but have very different phytoplankton populations. Lake Crescent has ten times the standing crop biomass of Lake Sorell but its greater turbidity restricts light penetration, and production per unit of surface per day and per year is only 2.6 times that of Sorell. With day rates of 25-(44)-93 mgCm−2 and annual production of 16.9 gCm−2 Lake Sorell could be regarded as oligotrophic. Consideration of standing crop biomass and morphometry however indicates oligo-mesotrophy. Lake Crescent with day rates of 35-(115)-250 mgCm−2 and annual production of 45 gCm−2 is moderately eutrophic. Incubations in constant light demonstrated considerable variation in production rates in different parts of Lake Crescent.
