ABSTRACT
The aim of the present study exploration centred on divergent assemblage of the marine macro algae visualized from Majali coast, Karnataka from Jan 2018-Jan 2019, to apprehend the seaweed diversity with consequential reverberating environmental parameters. Seaweed diversity was studied using random sampling method for computing the ecological diversity indices through three seasons Pre-Monsoon, Monsoon and Post-Monsoon, to know the richness and diverse nature in species population. In the present study, ANOVA one way (p<0.05) was performed between total seaweed abundance and the hydrological parameters, where the Tukey’s test projected the effect of environmental parameters on seaweeds abundance. The result showed significant differences in the mean of parameters during seasons in comparison to seaweeds diversity. The hydrological parameters differ with seasonal periods, geographical location and temporal variation. All the parameters showed significant changes in mean except for salinity,depicting some species like Ulva are capable of vital growth in all seasons, even in lesser than 15ppt or zero salinity regime. Clustering was used for representation of dendrogram using Bray-Curtis Similarity for identifying the seasonal variation in species assemblages and similarities between the groups
