In addition to having a significant biological impact on litter decomposition, soil fauna also contributes significantly to the release of nutrients like carbon and nitrogen. Understanding isopod demography and their involvement in soil health and ecosystem functioning was the main goal of this study. In order to adapt to the environmental circumstances in their habitat and lessen their impacts, isopods adopt a variety of activity patterns. Samples of soil were collected from three distinct locations in Tamil Nadu and Kerala, and their physicochemical and texture characteristics were examined. The soil factor affecting Porcellio scaber density was identified using Principal Component Analysis (PCA) and Correspondence Analysis. Porcellio scaber population density was found to be lowest during the pre-monsoon season and highest during the post-monsoon season. Many organisms move to the deep layers during the pre-monsoon season because of the low moisture content. The PCA analysis showed that the distribution of Porcellio scaber was positively impacted by the following essential factors: temperature, exchangeable base, sand, clay, magnesium, and silt.
