Effects of increasing soil moisture on Antarctic desert microbial ecosystems

open access: yesConservation Biology, Volume 38, Issue 4, August 2024.
Abstract Overgeneralization and a lack of baseline data for microorganisms in high‐latitude environments have restricted the understanding of the microbial response to climate change, which is needed to establish Antarctic conservation frameworks. To bridge this gap, we examined over 17,000 sequence variants of bacteria and microeukarya across the ...
