This data package includes the abundance of microbial operational taxonomic units (OTUs) for samples collected during the austral summer of 2012-2013 in the Lake Hoare and Goldman Glacier Basins of Taylor Valley, Antarctica. A total of twenty samples from on- and off-water track soils were collected and analyzed. Samples were collected from the Lake Hoare Basin on 27 December 2012 and from the Goldman Glacier Basin on 4 January 2013.

Populations of Plectus murrayi, a mesophilic nematode, have been increasing in the McMurdo Dry Valleys, Antarctica over the past three decades. In contrast, most other Antarctic nematode species, including Scottnema lindsayae, have experienced constant population declines over the same time period due to climate change related increases in summer temperatures and wetting occurrences. To determine why P.

Elemental stoichiometry is a useful theoretical framework for understanding the sources and controls on nutrient availability that can structure the composition, diversity, and life history of biotic communities. One such relationship, as postulated by the growth rate hypothesis (GRH), is that organismal development rate is positively linked to cellular phosphorus (P).

This data package includes ecological parameters of biocrust and soil from samples collected in-situ within the Lake Fryxell Basin of the McMurdo Dry Valleys, Antarctica during December of 2019. Parameters include biological (ash-free dry mass, pigment concentration, and counts of soil invertebrates), physical (water content, electrical conductivity, and pH), and chemical properties (inorganic nitrogen, inorganic phosphorous, total nitrogen, and total organic carbon) of the surface soil, biocrust, and underlying soil.

This data package includes biophysicochemical properties of biocrust and soil samples collected in-situ within the Lake Fryxell basin of the McMurdo Dry Valleys, Antarctica during December 2022 at 64 different terrestrial locations. These parameters include biological (ash-free dry mass, pigment concentration, soil invertebrate counts), physical (gravimetric water content, electrical conductivity, pH), and chemical (inorganic nitrogen, inorganic phosphorous, total nitrogen, soil organic carbon) properties of the surface soil, biocrust, and underlying soil.
