![Contribution of springs to the lake. (A) Venn diagram of genera found in the Corral Springs biofilm, salt crust, Springs 1 and 2 (S1, S2 combined), Roberts Ranch/Wyman Creek (RS), and the lake water. (B) Mixing proportions calculated using SourceTracker using the lake water samples (LW1, LW2, and overnight incubated [ON]) and the salt crust as sinks, and the biofilm, RS, S1 and S2 as sources. “Unk” indicates “unknown source.” The Gibbs sampler was run for 10,000 iterations. -- Frontiers](https://i0.wp.com/astrobiology.com/wp-content/uploads/2026/02/Microbial-communities-of-selected.png?resize=1200%2C720&ssl=1)
