Microbes are the smallest known living organisms on Earth and can be found just about everywhere, even in the cold, Mars-like conditions of lava caves.
Diversity among the sites varied. Older lava tubes, those between 500 and 800 years old, hosted more diverse microbe populations than geothermically active sites or were less than 400 years old.
Researchers suspect it takes a while for microbes to colonize volcanic basalts, and as the environment around them changes, so does their community structure. In cooler caves, for instance, Proteobacteria and Actinobacteria are more prevalent. In younger lava caves, microbes tended to be more distantly related. This suggests competition is a stronger force in harsher environments, one that lowers the chance of closely related species living side by side.Several classes of bacteria, like Chloroflexi and Acidobacteria, existed at nearly all sites, regardless of age.
