INTERTIDAL CYANOBACTERIAL DIVERSITY ON A ROCKY SHORE AT BULEJI NEAR KARACHI, PAKISTAN AZRA BANO AND PIRZADA J. A. SIDDIQUI Abstract: The present study describes the species diversity of cyanobacteria on a rocky shore at Buleji near Karachi. Species of cyanobacteria were recorded from the surface sediments (edaphic), rock surfaces (epilithic), in rock-pool and open seawater. A total of 109 species were observed and classified under four orders and 24 genera. Eighty five species recorded in this study are new records for intertidal cyanobacteria from Pakistan. About 50% of observed cyanobacteria appeared to inhabit only one niche. A difference in the distribution and diversity of cyanobacteria was also observed with respect to tidal height. Three types of enriched media were employed to boost growth of less abundant cyanobacterial species. A high diversity of cyanobacteria from intertidal environment was observed.
