Abstract

Land snails have been divided into four different groups for this study: living adults, deceased adults, living juveniles and deceased juveniles. The three areas studied in southern Finland differed from each other in the quantity of land snail species and individuals present. The collected material can be inspected in many ways. The percentages of living and dead land snails, appearance frequencies of species and other results of the study are made apparent through charts and figures. Even results within a species have fascinating differences.
