Diversity indexes for the temporal analysis of Wiltshire brine. Three indexes were used to track changes in the microbiome of brine temporally: (A) Shannon diversity index, (B) Chao 1 richness, and (C) Heip’s evenness. The Shannon index of brine sampled on Day 0 and Day 20 differ significantly (p = ≤ 0.05, ∗∗p = ≤ 0.01, respectively) from brine sampled on Day 40 (A). No statistically significant differences were observed in the Chao 1 richness (B). Heip’s evenness index was significantly different between brine sampled on Day 0 and Day 40 (p = ≤ 0.05) (C).
