#microbial
Life does not end at the #sediment-#water-interface, it keep going down and down and down (less so on land). There is a #diversity continuum, and some of those #subsurface #microbial communities can be rather diverse.

How did (post-)colonial lab + public health #infrastructures create #microbial #standards? What configurations of (non-)humans did they support & how are they contested?

"As the amount of #methane has risen in the atmosphere over the past 15 years, it’s also gotten lighter and lighter. The scientists used a model to analyze those changes and found that only large increases in #microbial #emissions could explain both the rising methane and its changing weight.
While microbes in wetlands are largely natural, the tiny creatures can also pump out methane from reservoirs, agricultural lands and landfills."
#WeekendReading: Pederso et al., on the complex processes from deposition, dissolution, and precipitation of #calcareous #microbial mud along a fresh to saline water gradient.
#ClimateCrisis: Venezuela loses its last #glacier as it shrinks down to an ice field
https://www.theguardian.com/environment/article/2024/may/08/venezuela-loses-its-last-glacier-as-it-shrinks-down-to-an-ice-field
"#Venezuela is a mirror of what will continue to happen from north to south, first in #Colombia, #Ecuador, then in #Peru, #Bolivia, as #glaciers continue to retreat from the #Andes... The loss of La Corona marks the loss of the many #EcosystemServices that glaciers provide, from unique #microbial habitats to environments of significant cultural value"
Unraveling the Mysteries of Carbon and Nitrogen in the Bay of Bengal

"In the #oxygen minimum zone, where oxygen levels are depleted, #carbon and #nitrogen cycling takes on added complexity. #Microbial communities adapt to low-oxygen conditions, driving unique biogeochemical processes with far-reaching implications for marine ecosystems and global nutrient cycles."
Hidden #biosphere discovered beneath world's driest hot desert

Persistent #microbial communities in #hyperarid #subsurface habitats of the #Atacama Desert https://academic.oup.com/pnasnexus/article/3/4/pgae123/7646996
"In the upper 80 cm of playa sediments, microbial communities were dominated by #Firmicutes. Below 200 cm, a different microbial community was discovered, dominated by #Actinobacteria... this community might have colonized the soil 19,000 years ago, before being buried by playa deposits"

"Those #microbes found kilometers below the #seafloor will have been there 100 million years or more. The deeper they are, the less residual organic matter will be available for their growth and maintenance metabolism. Estimates are that a typical doubling time in these environments is in the order of 1000 years."
Discovery of the first #fractal molecule in nature
https://phys.org/news/2024-04-discovery-fractal-molecule-nature.html
Emergence of fractal geometries in the #evolution of a metabolic #enzyme: Franziska Sendker et al. https://www.nature.com/articles/s41586-024-07287-2
"They discovered a #microbial enzyme—citrate synthase from #cyanobacteria—that spontaneously assembles into a pattern known as the #SierpinskiTriangle. #ElectronMicroscopy and evolutionary #biochemistry studies indicate that this fractal may represent an evolutionary accident."

"Subterranean estuaries, where terrestrial #groundwater and seawater intermix, are vital zones of coastal #ocean ecosystems... these zones are poorly studied, despite facing escalating threats by future global changes."
Even inactive #DeepSea 'smokers' are densely colonized by #microbial communities https://phys.org/news/2024-03-inactive-deep-sea-smokers-densely.html
Inactive #hydrothermal vent microbial communities are important contributors to deep #ocean primary productivity: Amanda Achberger et al. https://www.nature.com/articles/s41564-024-01599-9
"When the flow of mineral-rich fluids dries up, the #BlackSmokers become inactive. Larger organisms migrate away to the next vent, but the #microbes have ways to adapt to the new conditions."
