Abstract
We currently lack a predictive understanding of how soil archaeal communities
may respond to climate change, particularly in Alpine areas where
warming is far exceeding the global average. Here, we characterized the
abundance, structure, and function of total (by metagenomics) and active
soil archaea (by metatranscriptomics) after 5-year experimental field warming
(+1 C) in Italian Alpine grasslands and snowbeds. Our multi-omics
approach unveiled an increasing abundance of Archaea during warming in
snowbeds, which was negatively correlated with the abundance of fungi
(by qPCR) and micronutrients (Ca and Mg), but positively correlated with
soil water content. In the snowbeds transcripts, warming resulted in the
enrichment of abundances of transcription and nucleotide biosynthesis. Our
study provides novel insights into possible changes in soil Archaea composition
and function in the climate change scenario.
