Cumulative detection probability as a function of the number of surveys for cave crayfishes (panel A) and cavefishes (panel B). Solid lines eDNA surveys and dashed lines are visual surveys. Cumulative detection probability (pc) was calculated as: pc = (1 - (1 – p)k, where p is detection probability at mean and reference levels (i.e., visual surveys, water not flowing, cave crayfishes, and coarse substrate) of predictor variables and k is the number of surveys.
