Background: Peatlands are expected to experience sustained yet fluctuating higher temperatures due to climate change, leading to increased microbial activity and greenhouse gas emissions. Despite mounting evidence for viral contributions to these processes in thawing permafrost, little is known about viruses in other peatlands. More generally, soil viral biogeography and its potential drivers are poorly understood at both local and global scales. Here, 87 metagenomes and five viral size-fraction metagenomes (viromes) from a boreal peatland in Northern Minnesota (from the SPRUCE whole-ecosystem warming experiment and surrounding bog) were analyzed for dsDNA viral community ecological patterns, and the recovered viral populations (vOTUs) were compared to a database of 261,799 vOTUs from diverse ecosystems. Results: Within the SPRUCE experiment, viral community composition was significantly correlated with peat depth, soil moisture, and carbon chemistry, including CH4 and CO2 concentrations, but not with ... : This zip package includes: 1) All vOTUs from the SPRUCE experiment, both predicted from viromes and total soil metagenomes, recovered in one or multiple samples. 2) All vOTUs in the Phages and Integrated Genomes Encapsidated Or Not (PIGEON) database. 3) A renaming key for the PIGEON database, with for each vOTU in the PIGEON database: our name for the contig, the original name for the contig as in the publication, and the publication the contig came from. 4) MAGs from the 2018 metagenomes and 2015-2016 metagenomes. Information on binning of these MAGs can be found in supplemental tables 4 and 5 of the manuscript. 5) A table with habitat origins for each of the vOTUs in the PIGEON database ...
