Higher contribution of globally rare bacterial taxa reflects environmental transitions across the surface ocean (https://doi.org/10.1111/mec.15026)
tiny snippet: "Here we identified the Spatial Abundance Distribution (SpAD) of individual prokaryotic taxa (16S rDNA-defined Operational Taxonomic Units, OTUs) across 108 globally-distributed surface ocean stations. We grouped taxa based on their SpAD shape (“normal-like”- abundant and ubiquitous; “logistic”- globally rare, present in few sites; and “bimodal”- abundant only in certain oceanic regions), and investigated how the abundance of these three categories relates to environmental gradients."
tiny snippet: Using a uniquely broad global dataset of 13 483 metagenomes, we analysed the microbiome structure and function of 25 host-associated and environmental habitats, focusing on potential interactions between bacteria and fungi.
The Microbiome Stress Project: Toward a Global Meta-Analysis of Environmental Stressors and Their Effects on Microbial Communities (https://doi.org/10.3389/fmicb.2018.03272)
would require very good metadata about stresses/treatments to a subset of metagenomes
