1. Natural spatial subsidies in continental Antarctic soil [K052_2001_2005_NZ_1]   CHILD DIFs
The soils of the McMurdo Dry Valleys are hypothesized to rely on external sources of nutrients (carbon, nitrogen, etc). The importance of these spatial subsidies on productivity and biological diversity ...


2. The legacy model vs the subsidy model to explain soil organic matter in the McMurdo Dry Valleys [K052_2004_2006_NZ_1]   CHILD DIFs
The Dry Valleys of Victoria Land, Antarctica, contain naturally simple ecosystems operating under extreme climatic conditions. Nutrients are limited and are thought to come from external sources from ...


3. A hot house experiment at Cape Bird to determine the effects of microclimate on plant establishment [K052_1982_1983_NZ_5]
A small perspex frame was placed over bare mineral soil adjacent to the mosses in Keble Valley to examine the effects of humidity, temperature and microclimate on plant establishment. Many green ...


4. Algae, fungi and actinomycetes from soils of Mt Erebus [K052_1982_1983_NZ_4]
Soil samples were collected from the crater of Mt Erebus. Yeast glucose agar and penicillin and streptomycin was used to culture thermophilic microbes, fungi and actinomycetes. Several thermophilic ...


5. Biological and biochemical studies of the plant, invertebrate and microbial communities in the Ross Sea Region [K052_1984_1985_NZ_1]
An expedition was undertaken in the 84/85 season with the aim(s): 1) to survey plant and microbial communities in the Terra Nova Bay area, 2) to conduct ecophysiological studies on the insects at ...


6. Decomposition, nitrogen mobilization, nitrogen fixation and the importance of lakeside foams in fellfield soils of the Garwood Valley [K052_1991_1992_NZ_1]
Nitrogen, a necessary nutrient for plants and microbes, is frequently limiting in soils. Nitrogen fixation and decomposition, both ways plants and microbes obtain nitrogen, are very slow processes ...


7. Floristic and ecological surveys of plants and microbes in the Garwood Valley [K052_1986_1987_NZ_1]
A general floristic and ecological survey of plants and microbes was conducted in the Garwood Valley/Joyce Lake area including vegetation mapping, collection and microscopic examination of algae and ...


8. Floristic surveys, vegetation mapping, soil animals and environmental parameters for algae growth at Cape Bird [K052_1982_1983_NZ_3]
A plant map for Keble Valley was produced and the water channels plotted to determine the factors involved in moss establishment and growth. Water and shelter were found to be the main factors. Temperature ...


9. The amount of nitrogen in the biotic and abiotic systems at Cape Bird measured from evaporated water samples and wind blown inputs [K052_1982_1983_NZ_2]
The amount of nitrogen in the biotic (flora and fauna) and abiotic (soils, ice and snow) systems at Cape Bird was determined by taking water from melt streams, snow or ice, acidifying and evaporating ...


10. The collection of fossils, qualitative microbial studies and nitrogen fixation rates of the soils from several sites in the Ross Sea region [K052_1980_1981_NZ_1]
Preliminary qualitative microbiological studies were conducted at several sites in the Ross Sea Region including Cape Bird, Taylor Valley, Wright Valley and Shapeless Mountain and Mistake Peak on ...


11. The effect of crude oil on Antarctic soils [K052_1982_1983_NZ_1]
Two small plots near a recently abandoned penguin colony and an area of moss free soil at Cape Bird were prepared by addition of 100ml of McKee crude oil. The plots were covered with steel mesh. These ...


12. The mean size and mean number of microbial organism for soil samples collected from Heald, Hahn and White Island terrestrial soils and White Island marine sediment [K014_1978_1979_NZ_3]
Samples of soils collected from Heald, Hahn and White Island were ground in a mortar and pestle with 20ml distilled water. Agar films for subsequent counting were prepared from these soil suspensions. ...
