ABSTRACT

This study delves into the fascinating world of intertidal life, comparing the biodiversity and abundance of two distinct rocky shores along the Sindh and Balochistan coasts in the northern Arabian Sea. Climate change and anthropogenic driver ultimately effect on benthic community which play a key role in functioning the ecosystem. Our findings unveil a hidden gem: Sunehri Beach, boasting higher species richness despite facing greater tidal influences. Mollusks, particularly gastropods, thriving in these rocky havens. The number of individuals per unit area of intertidal fauna was higher at Mubarak Village, which was dominated by mollusks and arthropods. Mollusks were consistently more abundant than other species. Balanus balanus is the common species found on both sides with the highest abundance, but population abundance and health significantly varied from one site to another. A Simpson’s Diversity Index of 0.075 suggests that Mubarak Village has a higher level of species richness than Sunehri Beach (0.133). This indicates that there was more abundance of the species at this location. The Shannon diversity index in Mubarak Village is 2.87 and 2.27 in Sunahri Beach which indicates the diversity is significantly greater in Mubarak Village. The study further highlights the crucial role of structural complexity in sustaining biodiversity and abundance of the benthic communities. They indicate that the significance of structural connectivity between habitats that influenced by the global environmental context. Our results advocate management strategies that prioritize the preservation of habitat complexity and consider the entire spectrum of habitats within tropical seascapes. By understanding these unique ecosystems, we can pave the way for sustainable coastal management and conservation of the diverse communities that call them home.
