The arid soils of the Antarctic Dry Valleys constitute some of the oldest, coldest, driest and
most oligotrophic soils on Earth. Early studies suggested that the Dry Valley soils contained …

Despite that soils may be the greatest repository of biodiversity on Earth, and that most
terrestrial ecosystem functions occur in the soil, research on the role of soil biodiversity in …

Recent applications of molecular genetics to edaphic microbial communities of the McMurdo
Dry Valleys and elsewhere have rejected a long-held belief that Antarctic soils contain …

Understanding the relationship between soil biodiversity and ecosystem functioning is
critical to predicting and monitoring the effects of ecosystem changes on important soil …

A combination of culture-independent and culturing methods was used to assess the
diversity of soil bacterial communities from four locations along 77° S in Victoria Land …

Biotic communities and ecosystem dynamics in terrestrial Antarctica are limited by an array
of extreme conditions including low temperatures, moisture and organic matter availability …

Cyanobacteria are major components of Antarctic Dry Valley ecosystems. Their occurrence
in lakes and ponds is well documented, however, less is known about their distribution in …

Abstract Ice-free areas occupy< 0.5% of Antarctica and are unevenly distributed across the
continent. Terrestrial ecosystem dynamics in ice free areas are strongly influenced by …

Ecological stoichiometry is a useful theoretical framework for understanding the sources and
controls on nutrient availability that structure the composition and diversity of biotic …

The Antarctic continent is widely considered to be one of the most hostile biological habitats
on Earth. Despite extreme environmental conditions, the ice-free areas of the continent …
