Ecological dichotomies arise in microbial communities due to mixing of deep hydrothermal waters and atmospheric gas in a circumneutral hot spring. Appl Environ Microbiol 87:e01598-21. https://doi.org/10.1128/AEM.01598-21.0099-2240https://scholarworks.montana.edu/handle/1/17184Understanding the source and availability of energy capable of supporting life in hydrothermal environments is central to predicting the ecology of microbial life on early Earth when volcanic activity was more widespread. Little is known of the substrates supporting microbial life in circumneutral to alkaline springs, despite their relevance to early Earth habitats.en-UScopyright American Society for Microbiology 2021https://web.archive.org/web/20181013000300/https://journals.asm.org/content/statement-author-rightshttps://web.archive.org/web/20181013000300/https://journals.asm.org/content/statement-author-rightsecological dichotomiesmicrobial communitieshydrothermal watersatmospheric gasArticle
