Effect of distance on occurrence probability of MOTUs detected by eDNA. MOTUs occurrence probability was modelled using Hierarchical ModelIing of Species Communities statistical framework, enabling us to estimate a separate distance coefficient for each species. (A) Overall effect of distance for all 143 MOTUs, (B) a subset of pelagic MOTUs from the family Scombridae, (C) mixed habitat MOTUs from the family Pomacentridae, and (D) benthic/demersal MOTUs from the family Acanthuridae. In (A) species coefficient estimates are coloured by pelagic (blue) and benthic/demersal habitat type (orange), in (B-D) colour represents the effect of distance. A total of 1000 posterior estimates were calculated for each MOTUs. Each line represents an MOTUs with coloured histograms showing the 95% confidence intervals of parameter posterior estimates. Points represent the median of the posterior estimates and thick solid lines and thin solid lines represent the 60% and 80% confidence intervals, respectively. The vertical line represents the reference point to determine coefficients significance.
