Highlights•Acidic microbiomes are tractable model systems in biogeochemical cycling
studies.•Their spatial diversity patterns have been resolved at several different scales.•The …

Terrestrial geothermal ecosystems, as a representative of extreme environments, exhibit a
variety of geochemical gradients, and their microbes are thought to be under high stress …

Geothermally heated regions of Earth, such as terrestrial volcanic areas (fumaroles, hot
springs, and geysers) and deep-sea hydrothermal vents, represent a variety of different …

High-temperature geothermal springs host simplified microbial communities; however, the
activities of individual microorganisms and their roles in the carbon cycle in nature are not …

Using a culture-independent method that combines CARD-FISH, qPCR and 16S rDNA, we
investigated the abundance, community structure and diversity of microbes along a steep …

Chemosynthetic sediment and planktonic community composition and sizes, aqueous
geochemistry and sediment mineralogy were determined in 15 non-photosynthetic hot …

Little is known about the distribution and ecological functions of abundant, intermediate, and
rare biospheres and their correlations with environmental factors in hot springs. Here, we …

At present, nitrates were widely used to remediate sulfur-rich sediment in black odorous
rivers. However, the optimal nitrate dosage and influencing factors during remediation have …

Nitrate-driven sulfide oxidation has been proved a cost-effective way to control sediments
odor which has long been a universal problem for urban rivers in south China areas. In this …

Microbial biogeography studies, in particular for geothermal-associated habitats, have
focused on spatial patterns and/or individual sites, which have limited ability to describe the …
