Abstract
The present paper dealt with diversity of the genus Cylindrospermum from different aquatic and semi aquatic habitats of Meerut and adjoining areas of Western Uttar Pradesh, Bharat. Cylindrospermum is a genus of heterocystous cyanobacterium. The species of the Cylindrospermum occur periodically in aquatic and semi-aquatic habitats including flooded paddy fields. In the present investigation, a total of 23 taxa belonging twenty species, two varieties and one forma of the genus Cylindrospermum from three different aquatic and semi aquatic regimes along with their distribution pattern and species diversity in three different sites, were reported. Additionally, in the present communication, the phylogenetic relationship, arrangement of the hierarchical clusters, dendrogram using Ward Linkage Euclidean Distance Proximity matrix, Pearson correlation linear relationship and cross-correlation coefficient of 23 taxa of Cylindrospermum including C. ecballisporum, C. dobrudjense, C. licheniforme, C. bourrellyi, C. muscicola var. kashmiriense, C. muscicola var. variabilis, C. desikacharyi, C. identatum, C. pellucidum, C. minutissimum, C. majus, C. stagnale f. variablis, C. kazachstanicum, C. gregarium, C. breve, C. stagnale, C. michailovskoense, C. skujae, C. longisporum, C. voukii, C. alatosporum, C. marichicum and C. rectangularis from Meerut and adjoining area, were reported. Phylogenetic relationship on the basis of morphological characters indicated the formation of two major and seven minor groups. Hierarchical clusters analyses illustrated the arrangement of the clusters while dendrogram using Ward Linkage formed two clusters I and II. Based on Pearson’s correlation linear relationship, morphological characters showed both positive and negative relationship while Euclidean Distance Proximity Matrix reveals how close the characters are to each other.
