Distribution of rare and endangered terrestrial mollusks in Central Uzbekistan

Abstract

The purpose of the research is to analyze the distribution, anatomical and morphological aspects of dryland mollusks found in the Central Uzbekistan region, and to provide information on their ecology, distribution, limiting factors, and conservation measures. The material collection was carried out according to the methodology of A.A. Shileyko. Based on the results of the collected research, it can be concluded that due to the necessity of moisture for mollusks in the ecological complex, they can be classified into three major groups: hygrophilous, mesophilous, xerophilous, and mesoxerophilous species. The research results indicate that out of the 7 species found in the Central Uzbekistan region, currently, 28.75% are classified as critically endangered, approximately 42.85% are considered vulnerable, and 28.75% are endangered. The dryland mollusk species found in the Central Uzbekistan region are categorized ecologically into hygrophilous, xerophilous, and mesoxerophilous types. In order to conserve and monitor the population of dryland mollusk species in the Central Uzbekistan region, it is recommended to first protect their habitats, particularly by halting deforestation and degradation of habitats where mollusks reside, secondly, to restrict extraneous use of these areas as pastures, and thirdly, to undertake research on their habitat preferences and biology to prevent their extinction as a species.
