Extended Data Table 2 Detailed statistical ecology analyses and results

From: Orbit-to-ground framework to decode and predict biosignature patterns in terrestrial analogues

  1. 1) Biosignature probabilities are presented herein as %Col, as this is the ratio tested for significance in the χ 2 test. 2) χ 2 test of independence of ratios of colonization; 3) %Col of the patterned ground unit is 50% and percent area cover for microstructures of the unit was 40.3%. Patterned ground was excluded here from chi-square tests to include only endolithic morphotypes. 4) In Study ES-1, %Col by BSC was 0% for the bare salar surface microhabitat and 100% for the microstructures; these microhabitats were excluded from chi-square tests to include only endolithic morphotypes; 5) In Study ES-1, float (2.4 ± 1.5 %Col) was analyzed separately from sand (12.5 ± 7.2 %Col), as well in a combined (when both are present) category (4.7 ± 3.3 %Col), as in Study ES-2.
