Biofilm Microphytobenthic Biomass in Mudflats of Buayan, General Santos City

This study investigated the impact of shading on microphytobenthic biomass in Buayan intertidal mudflats, where a mangrove planting project is underway. The research aimed to assess the potential effects of shading, specifically the presence of mangroves, on microphytobenthos in the area. Three sites representing different sections of the intertidal area were selected for sampling: two unshaded sites and one site located under mangroves Using spectrophotometric chlorophyll measurements as a proxy for microphytobenthic biomass, the study compared the biomass levels between the shaded areas under mangroves and the open areas. The findings of the study indicated a consistent and significant reduction in microphytobenthic biomass in the shaded areas compared to the unshaded regions. This suggests that shading, particularly caused by the presence of mangroves, has an impact on the productivity and distribution of microphytobenthos in the Buayan intertidal mudflats. A significant difference in microphytobenthic (MPB) biomass was observed between the mudflats in under-mangrove mudflats (shaded area under mangroves) and near-mangrove mudflats (unshaded area near the mangroves). This finding suggests that the presence of mangroves also creates a favorable environment for the growth and increase of MPB biomass.
