FIGURE 4 in Range sizes of groundwater amphipods (Crustacea) are not smaller than range sizes of surface amphipods: a case study from Iran

FIGURE 4 Violin plots, representing maximum linear extent for Gammarus and Niphargus species delimited using ABGD (A) and bPTP (B). The white dot in the middle indicates the median value in the range size, the thick black bar in the center represents the interquartile range and the thin black line shows 95% of all data. The distributions of surface species are not larger than the distributions of subterranean species (Mann-Whitney U test, p = 0.794 (A), p = 0.837 (B)). MOTUs found on a single localities are excluded.
