Application and Efficacy of diatom diversity indices for water quality evaluation of Chambal River System

Abstract

Species richness along environmental variables reveals a variety of patterns. In the present paper, we investigated the relationship between diatom communities and abiotic factors. About seven different species richness diversity indices were calculated for 27 sampling sites and Spearman’s rank correlation was determined to reveal the relationship between environmental variables and species diversity index. In total, 131 different diatom taxa were identified during the study
