Figure 2. Time in hours until disappearance of eDNA, illustrated as Kaplan-Meier plots. Survival analysis with censored data: (a) stratified on spiked (black, aq. 2,4,6,8,12,14,16,18,22,24,26,28) versus shrimp DNA (red, aq. 1,3,5,7,11,13,15,17,21,23,25,27), (b) pH low (black, aq. 1, 3, 4, 6,11,13,14,16,21,23,24,26) versus pH high (red, aq. 2,5,7,8,12,15,17,18,22,25,27,28) and (c) organic material absent (black, aq. 1,2,6,7,11,12,16,17,21,22,26,27) versus present (red, aq. 3,4,5,8,13,14,15,18,23,24,25,28)
