Abstract
Intertidal isopods are a group of successfully surviving organisms in the littoral region of the sea. The continuous exposure to human activities and other botic and abiotic stresses can influence their distribution and diversity along the seashore. Air and water temperature, salinity, pH, and presence of nutrients such as silicate, nitrate and phosphate are studied for their influence on some of the selected intertidal isopods found in three different beaches of the southern Kerala. Monthly data was collected for the water samples and four different isopod species found in the intertidal region and the significance of their interaction was calculated with the help of SPSS, using two-way ANOVA. The statistics shows a vivid relationship between these abiotic factors and isopods under study.
