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)
