Climate warming in polar regions is associated with thawing of permafrost, resulting in significant changes in soil hydrology, biogeochemical cycling, and in the activity and composition of soil communities. While ongoing, directional climate warming can elicit such responses over decadal time scales, their manifestation typically occurs as discrete thawing pulses. Indeed, in the McMurdo Dry Valleys of Antarctica abrupt changes in community structure and biogeochemical cycling in terrestrial and aquatic ecosystems following a summer warming event (Jan.

During the 2017-2018 austral summer, a survey of soil invertebrate diversity and abundance was conducted throughout the Shackleton Glacier region of Antarctica to investigate whether habitat suitability, taxonomic diversity, and community composition follow predictable temporal patterns after the Last Glacial Maximum (LGM). Soil samples were collected along elevation transects from twelve ice-free areas to capture maximum variation in soil properties, geochemistry, and surface exposure age.
