SPATIAL VARIATIONS IN THE BENTHIC DIATOM FLORA AND ITS DIVERSITY IN THE HIGHLAND-PLATEAU RIVERS (CENTRAL INDIA)
Diatoms constitute over 80% of the primary producers in the highland stream and river ecosystems. The study area is a north-eastern part of the Central Highlands ecoregion located to north of the tropic of Cancer between Narmada in the south and Gangetic Plains in the north. Their floras consist of total 276 taxa, 206 and 212 taxa in Ken and Tons, respectively and are quite similar (Sorensen Similarity Cs 0.67). Flora is highly similar within each river (Cs 0.65- 0.9) but varies among their corresponding sections (upper to mouth) as Cs is low (0.44 - 0.52). A general longitudinal decline in the species richness and diversity is hence evident in these rivers attributed to reduction in substrate size and its heterogeneity from source to mouth. This study examines spatial distribution of diatom communities from the rivers Ken and Tons in Central India. Studies will be useful to understand the regional patterns of diatom diversity and formulate reference conditions in these and other rivers of this region. Aim of this study to examine the spatial distribution of diatom communities and species diversity in the highland - plateau rivers Ken and Tons.
