Carbon, nitrogen and temperature controls on microbial activity in soils from an Antarctic dry valley
Abstract The Antarctic dry valleys are characterized by extremely low temperatures, dry conditions and lack of conspicuous terrestrial autotrophs, but the soils contain organic C, emit CO2 andExpand

Controls on the distribution of productivity and organic resources in Antarctic Dry Valley soils
The Antarctic Dry Valleys are regarded as one of the harshest terrestrial habitats on Earth because of the extremely cold and dry conditions. Despite the extreme environment and scarcity ofExpand

Enzymatic activities and microbial communities in an Antarctic dry valley soil: Responses to C and N supplementation
Abstract The soils of the Antarctic dry valleys are exposed to extremely dry and cold conditions. Nevertheless, they contain small communities of micro-organisms that contribute to the biogeochemicalExpand

Isotopic evidence for the provenance and turnover of organic carbon by soil microorganisms in the Antarctic dry valleys.
The extremely cold and arid Antarctic dry valleys are one of the most environmentally harsh terrestrial ecosystems supporting organisms in which the biogeochemical transformations of carbon areExpand

Distribution and dynamics of soil organic matter in an Antarctic dry valley
Abstract Terrestrial ecosystems in the Antarctic dry valleys function under extremely cold and dry climatic conditions that severely constrain C and N cycling and, like other polar regions, areExpand

Influence of Temperature on Water‐Extractable Organic Matter and Ammonium Production in Mineral Soils
Cold (room temperature) and hot water (70-80°C) extraction methods have been used to assess the availability of organic matter and N in soil; however, the influence of temperature on theirExpand

Occurence of arbuscular mycorrhiza and extomycorrhiza on Leptospermum scoparium from the Rakaia catchment, Canterbury.
Leptospermum is one of only three New Zealand genera that are colonised by ectomycorrhizal (EM) fungi, and L. scoparium is one of the very few New Zealand species that can be colonised by bothExpand

Release of mineral nitrogen from plant root nodules
Abstract Root nodules from a variety of nodulated leguminous and non-leguminous plants were added to soil samples and the net release of mineral N was monitored periodically for 56 or 98 days. OverExpand

Postharvest organic matter removal effects on FH layer and mineral soil characteristics in four New Zealand Pinus radiata plantations
Abstract The effects of three postharvest organic matter removal treatments on fermentation-humus (FH) layer and soil characteristics were compared in replicated trials in four second rotation NewExpand
