Abstract

Similarity, diversity and equitability of snail communities in lower mountain zone in the Tatra Mountains

Highlights

There is still a quite limited number of malacological studies concerning coenological problems
A very low spe£ies diversity H', along with extremely varied values of equitability J', is characteristic for communities inhabiting biotopes whose conditions are unfavourable for snails
A few studies deal with phytosociological characteristics of habitats or analyze relations between particular species and species associations with biotopes (Urbanski 1939, Orozdowski 1963, Ozi~czkowski 1972, 1974, Oyduch 1980)

Summary

Introduction

There is still a quite limited number of malacological studies concerning coenological problems. Before 1950 the mollusc fauna of Poland was investigated mostly from the faunistic or systematic point of view A few studies deal with phytosociological characteristics of habitats or analyze relations between particular species and species associations with biotopes (Urbanski 1939, Orozdowski 1963, Ozi~czkowski 1972, 1974, Oyduch 1980). 646/P~DUN/2016 allocated to the activities of disseminating science and by the courtesy of the Rector of the AGH University of Science and Technology, Cracow methods appl~ed are similar to those used in plant sociology (Jungbluth 1975). No method has been found applicable to comparisons of the mollusc communities of physiographically remote regions whose biotop~. The paper is an attempt at such an analysis based rather on the structural indexes commonly used in ecology of animal communities (e.g. birds: Glowacinski 1975, 1981) than on the species composition
