1. A quantitative survey of mosses in the McMurdo Sound region [K042_1976_1977_NZ_3]
A quantitative survey of the ecology of mosses in the McMurdo Sound region was conducted in the 1976/77 field season. Moss was found around streams below the Rhone, Hughes and Calkin Glaciers in the ...


2. 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 ...


3. 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 ...


4. Determination of the unique evolutionary patterns that prevail in the Antarctic springtail (Gomphiocephalus hodgsoni) [K025_2006_2007_NZ]
The energetic budgets (activity) of Antarctic springtails (Gomphiocephalus hodgsoni) was investigated at Cape Bird, Ross Island and the Garwood Valley, McMurdo Dry Valleys to determine the unique ...


5. Distribution data and samples of non-marine algae for culture and DNA analysis to determine evolution and dispersal of algae along a latitudinal gradient [K124_2003_2004_NZ_1]
Algae populations at different points on a latitudinal gradient within the Ross Sea sector were investigated. At Cape Hallett, the distribution of the different algal communities were mapped by a ...


6. 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 ...


7. GIS analysis, biological samples (soil microorganism, invertebrate and plant), automatic weather station data and vegetation and invertebrate surveys to determine the terrestrial biocomplexity of the McMurdo Dry Valleys [K020_2008_2009_NZ_1]
The McMurdo Dry Valleys are the largest area of snow-free land in Antarctica. Managers ability to promote and protect these areas would benefit if we knew the biodiversity present and what controls ...


8. GPR surveys, meteorological and hydrology data from the Joyce, Garwood and Hobbs glaciers in the McMurdo Dry Valleys to investigate glacier-permafrost interactions [K064_2008_2010_NZ_1]
The aim of this study was to develop an understanding of the interactions between glaciers and their permafrost beds that will permit models of glaciers to realistically parameterise ice motion. Improvement ...


9. Genetic sequencing of terrestrial invertebrates along the latitudinal range of the Ross Dependency to determine patterns of biodiversity, phylogenetic relationships and levels of gene flow among populations [K028_1999_2008_NZ_1]
Molecular techniques (allozyme electrophoresis and mitochondrial gene sequencing) were used to characterise the Antarctic terrestrial biodiversity along the latitudinal range of the Ross Dependency ...


10. Genetic variability and patterns of colonisation in Antarctic mosses [K022_1992_1995_NZ_1]
The geographic and microgeographic organisation of variation at genetic marker loci in mosses of the McMurdo Sound region was investigated. Samples of five species of mosses including Bryum argenteum, ...


11. 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 ...


12. Physical, chemical and biological characteristics of soils from the upper Garwood Valley, Ross Sea Region, 2002-2006. [K052_2004_2005_NZ]   PARENT DIF
These data consist of a number of subsets of soil samples gathered from the upper Garwood Valley in January 2002, January 2003, January 2005 and January 2006. Replicate randomly-located samples of ...


13. 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 ...


14. The use of computer models to predict changes in patterns and processes of terrestrial ecosystems in Antarctica: real data from automatic weather stations and digital cameras, dust samplers and soil samples [K024_2007_2008_NZ_1]
Field work was carried out to add to the creation of a dynamic geographic information system in which the specific observations about patterns and processes of the physical environment, plus observations ...
