FIGURE 4. Morphometric comparison of populations (marked by the name of the tree and height of the hollow position): asize distribution in shell length—shell breadth space; b—size distribution in aperture length—aperture breadth space; c—shell length / shell breadth (l/b) ratio and aperture length / aperture breadth (lps/bps) ratio; d—ration of specimens with circular shells (% shell) and with circular apertures (% apert). Whiskers—standard error of the arithmetic mean.
