Editorial: Life Under Pressure: Microbial Adaptation And Survival In High Pressure Environments
A quantitative overview of Earth’s biomass has long been lacking, despite its importance for understanding the biosphere. The first global estimate—approximately 550 gigatons of carbon (Gt C)—reveals stark disparities across […]

Non-thermodynamic Factors Affect Competition Between Thermophilic Chemolithoautotrophs From Deep-sea Hydrothermal Vents
Various environmental factors, including H2 availability, metabolic tradeoffs, optimal growth temperature, stochasticity, and hydrology, were examined to determine if they affect microbial competition between three autotrophic thermophiles.
