WebMar 19, 2024 · For each simulated data, several sampling efforts are repeatedly executed and MultSE calculated. The mean value, 0.025 and 0.975 quantiles of MultSE for each sampling effort across all simulated data are then estimated and standardized regarding the lowest sampling effort. The optimal sampling effort is identified as that in which the … WebThe choice of units of ‘equal’ sampling effort may strongly affect predictions about the relative total species richness of sites. Moreno & Halffter conclude that their methods may be applied to any other biological group. This is true in principle, but there is a major caveat: they are Table 1.
