Abstract:
The algal ecology of two Antarctic lakes, Lake Vanda, Wright Valley and Lake Miers, Miers Valley, were studied, and extensive collections were made of littoral and terrestrial algae, lichens and mosses. Samples of planktonic microorganisms were collected from both lakes by inserting a rubber tube through a hole drilled in the ice layer and pumping water through nylon filters at the surface. Large
... quantities of microscopic plants, principally blue green algae and diatoms, as well as a small number of Rotifers and Chlamydomonas. A filamentous green alga was found in Lake Miers and preliminary investigations suggested that it was a species of Ulothrix. Samples were examined and specimens were drawn and photographed. Samples were cultured for further studies to investigate encystments, hibernation stages, special behaviour and other life history phenomena. Water temperature, light intensity and penetration and electrical conductivity were measured at sampling depths. Colour and turbidity were noted, and pH was determined. Water samples were also chemically analysed. Terrestrial and littoral algae were collected from as many diverse habitats as possible for detailed studies. Specimens of each type of plant collected was deposited in the herbarium of the botany department at Victoria University of Wellington.
