Site-occupancy detection model estimates and habitat covariates.

Posterior mean and 95% credible interval (CI) for model regression coefficients: probability of eDNA site occupancy (ψ), true capture (θ₁₁), false-positive inference capture (θ₁₀), true detection (p₁₁), and false-positive test detection (p₁₀). Posterior inclusion probabilities (PIP, or proportion of iterations included in the model) of covariates linked to each parameter are also included. Model covariates included visual benthic cover, site depth, site position (X-Y coordinates), sample year, and the interaction of benthic cover and site depth (Cover:Depth) and position coordinates (X:Y). Coefficients with CIs that do not overlap zero and model covariates with PIP > 0.5 (the threshold applied to the most important model predictors, [<a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0318414#pone.0318414.ref038" target="_blank">38</a>]), are bolded. The probability of absence (1-ψ), capture false-negative (1-θ₁₁), capture true-negative (1-θ₁₀), false-negative detection (1-p₁₁), and true-negative detection (1-p₁₀) are the complements of ψ, θ₁₁, θ₁₀, p₁₁, and p₁₀, respectively.
