The McMurdo Dry Valleys, Antarctica, are experiencing rapid landscape scale change including increased glacial melt, the expansion of water tracks, thermokarst formation, an increase in the extent of the soil active layer, lake level rise, and altered stream flow. The impacts of these changes for biological communities are currently unknown. The goal of this study was to conduct surveys and experiments in three Dry Valley soil habitats that are expected to undergo change: water tracks, lake margins, and active layer profiles.

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.
