Graphic results. Plots representing: A. The different values of species richness observed with the mini-round box method and the combined survey (mini-round box + visual and acoustic survey); B. The differences in community composition resulting from the two sampling methods (PCoA; orange: mini-round box; light blue: combined survey); C. The mean mobility index of the orthopteran communities sampled with the two survey methods; D. The observed trend of mini-round box accuracy (%) in relation to the mean grass height along transects; E. The observed differences in terms of mini-round box accuracy (%) between the two study sites investigated in this research.
