Co-variation in soil biodiversity and biogeochemistry in northern and southern Victoria Land, Antarctica
Data from six sites in Victoria Land (72-77degrees S) investigating co-variation in soil communities (microbial and invertebrate) with biogeochemical properties show the influence of soil properties on habitat suitability varied among local landscapes as well as across climate gradients. Species ric...
