Abstract:

The new approach to complex studying variability qualitative and quantitative konchological parameters of land snail on the example of Xeropicta krynickii Kryn. (Mollusca: Gastropoda: Geophila: Hygromiidae) has been approved.

The material for the study is based on 10 samples of spatially separated populations of the species that lived in different biotopic and climatic and geographical conditions with different anthropogenic (urbo-, technological and recreational) load. There was no population screening, directed at the accumulation of xeropicta with a certain background color shells in specific habitats: in each of the test sample ratio of clams with shells background various shades close to that in the general population. It is found that the color of the strips on the shell at X. krynickii plays an important role in adaptation to the environment and is a representative feature within the study of the species.

Biserial correlation factor can be successfully used to analyze the possible connection of qualitative and quantitative konhological traits of terrestrial mollusks, in particular, gigromiid. The most significant figure to the mouth of the shell perimeter.
