1. Molecular genetics (DNA comparisons) of Prasiola crispa and Prasiola calophylla, two species of widspread Antarctic algae [K053_1993_1994_NZ_3]
Two species of widespread Antarctic algae were investigated with molecular genetics approaches to determine if they are two separate species. Prasiola crispa usually forms a sheet like growth on moist ...


2. Ecological survey of the birds, algae, lichen, fungi, and invertebrates on ice free areas of the Edward VII Peninsula, Marie Byrd Land [K053_1987_1988_NZ_3]
A 5-6 week remote field expedition was carried out to visit all rock outcrops in the Edward VII Peninsula, Marie Byrd Land to make a general biological survey of the region and assemble good plant ...


3. Algae cultures from air trap samples, snow samples and algal surveys from Scott Base, the Ross Ice Shelf and Victoria Valley to determine the dispersal of algae by wind within Antarctica [K053_1990_1991_NZ_2]
The dispersal of algae by wind within Antarctica was investigated by testing four techniques for detecting viable algae in the air: 1) High through put 'jet' spore samples, 2) Clinical monitors, 3) ...


4. Assessment of the importance of biological nitrogen fixation in the terrestrial ecosytem: Nitrogen fixation rates of Nostoc cyanobacterial mats in the Garwood Valley and at Cape Royds [K053_1986_1987_NZ_1]
Microbes with the nitrogenase enzyme on mosses and soils, particularly the cyanobacteria Nostoc, were examined to investigate the extent and magnitude of the nitrogen fixation process. Sample cores ...


5. Detailed descriptions and culturing of Oscillatoriaceae algae from Cape Royds and the Garwood Valley [K053_1986_1987_NZ_2]
The sites of the first detailed account of Cyanophyta in the Ross Sea Region (West and West, 1911) collected by Shackleton's 1907-09 expedition were revisited and detailed descriptions of Oscillatoriaceae ...


6. Detailed descriptions and culturing of Prasiola calophylla algae from Cape Royds and the Garwood Valley [K053_1986_1987_NZ_3]
A detailed investigation of the autoecology, morphology and life history of Prasiola calophylla were conducted to extend the existing data for the species. Data on distribution and growth patterns ...


7. Distribution and feeding habits of Gomphiocephalus hodgsoni at Cape Geology/Botany Bay, Antarctica [K053_1993_1994_NZ_2]
Data was obtained on distribution and feeding habits of the Collembolan Gomphiocephalus hodgsoni at Cape Geology/Granite Harbour. A considerable amount of descriptive data has been collected regarding ...


8. Ecological survey of the algae, lichen, fungi, and invertebrates on ice free areas of the La Gorce Mountains [K058_1996_1997_NZ_1]
A detailed study of far south ecosystems was conducted at La Gorce Mountains and nearby nunataks. A general biological survey was carried out describing the occurrence of any organisms encountered ...


9. Examination of introduced algae from foodstuffs and other foreign items brought to Antarctica [K053_1990_1991_NZ_1]
The impact of non-indigenous algae into Antarctica was investigated at Scott Base and was limited to soil particles adherent to fresh vegetables flown in from New Zealand (lettuce and potatoes). Preliminary ...


10. Systematic survey and abundance investigations of the algae in the meltpools of the McMurdo Ice Shelf [K053_1987_1988_NZ_1]
A qualitative and quantitative survey was made of algae in aquatic habitats on the McMurdo Ice Shelf. The majority of the work was conducted in eight ponds of diverse chemical characteristics in the ...


11. Systematic survey and abundance investigations of the microfauna (tardigrades, nematodes and rotifers) in the meltpools of the McMurdo Ice Shelf [K053_1987_1988_NZ_2]
Quantitative examinations of the microfauna associated with the algal felts in small melt pools on the McMurdo Ice Shelf in the vicinity of Bratina Island off the northen tip of Brown Peninsula was ...


12. Taxonomic and ecological survey of the terrestrial algae in the Ross Sea Region (McMurdo Dry Valleys, Marble Point, Cape Bird, Mt Erebus) [K053_1980_1981_NZ_1]
A taxonomic and ecological survey of the terrestrial algae was conducted in the vicinity of Lake Fryxell, Taylor Valley and Cape Bird and supplemented with samples from Marble Point, the lakes and ...


13. The taxonomy and distribution of algae cultured from samples from Granite Harbour: Oscillatoriales and Cyanobacteria [K053_1993_1994_NZ_1]
Samples were removed from the complete range of habitats supporting algal growth at Granite Harbour. A total of over 190 samples were examined microscopically and a taxonomic list was compiled. Cultures ...


14. Vegetation distribution (distribution mapping and microscopic examination) at Cape Bird [K053_1982_1983_NZ_2]
Extensive vegetation mapping and microscopic examination of sample material was completed at Cape Bird in detail enough so that maps were produced marking the location of all major algal, moss and ...


15. Vegetation distribution (maps, soil temperature, and microscopic examination) on the surface of heated ground at Tramway Ridge, Mt Erebus [K053_1982_1983_NZ_1]
Descriptions of the vegetation distribution on the surface of steam heated warm ground, especially in relation to temperature gradients from cold to hot areas was investigated on the summit of Mt ...
