Climatic and environmental constraints on aboveground-belowground linkages on the Antarctic Peninsula

On the samples, we measured: Soil chemical parameters, including: gravimetric soil water content, inorganic extractable nitrogen (KCl extracts measured on a Lachat autoanalyzer), extractable phosphate (NaHCO3 extracts measured on a TrAAcs), total and organic carbon and nitrogen (measured on an elemental analyzer), pH (1:2 soil solution using pH meter), and electrical conductivity (1:5 soil solution using EC meter) Soil and vegetation biotic community, including: nematode diversity and abundance (species level), tardigrade and rotifer abundance, microarthropod diversity and abundance (species level), microbial biomass (chloroform fumigation extraction measured on a Shimadzu TOC analyzer), bacterial 16S rRNA gene sequences, fungal ITS1 sequences, and metagenomic sequences
