FIG. 2 in Selection and habitat-speci®c allozyme variation in the self-fertilizing land snail Cochlicopa lubrica (O. F. MuÈller)

FIG. 2. Habitat-speci®c distribution of the 784 individuals of Cochlicopa lubrica. All individuals are homozygous, either with Aat 1`20 ' or with Aat 1`80 '. Exposed, open habitats are shown with light boxes while moist and shady habitats are superimposed on grey background. Adjacent populations which have been analysed in pair-group comparision are shown in the upper part (see arrows). p values are calculated with standard chi-square tests or, in one case, with Fisher's Exact Test. Habitat structures of each population are summarized in the Appendix.
