The bioindicator properties of oribatid mites in soil fauna of Kashkadarya region

Abstract

This article discusses the loss of bioindicator characteristics in oribatid mites found in the Kashkadarya region due to various anthropogenic and environmental factors. The study, conducted during the spring and summer of 2023, focused on pine and spruce gardens surrounding the Shortan gas-chemical industrial area. The results of our research identified 23 species, including Ornithonyssus bursa, Geratoppia quadridentate, Furcoribula furcillata, Perlohmannia altaica, Liochthonius kirghisicus, Asiacarius elongatus, Liochthonius hystricinus, Cultroribula dentata, Epilohmannia cylindrica and Michelia paradoxa with bioindicator properties. Changes in these indicators of species primarily occurred in the A soil layer, up to 10 cm deep. The study found that the primary factor influencing these changes was not the chemical waste from the industrial plant but rather acid gases resulting from burning companion gases, leading to acid rain formation when mixed with precipitation.
