SPECIES DIVERSITY INDICES IN MARINE BENTHIC COMMUNITIES AS A POLLUTION INDICATOR IN THE UPPER GULF OF THAILAND
NITTHARATANA PAPHAVASIT and TWESUKDI PIYAKARNCHANASummary: Comparative studies of species diversity indices in marine benthic communities were made from pollution survey data in the Upper Gulf of Thailand from 1974-1976. The areas compared were the northwestern coastline from Samut Sakhon Province to Petchaburi Province (Area A), the northeastern coastline from Samut Prakan Province, Ko Sichang to Laem Chabang in Chonburi Province (Area B), the western coastline from Area A on down to Hua Hin in Prachuap Kiri Khan Province (Area C) and the eastern coastline from Area B to Ko Juang in Rayong Province (Area D). The average species diversity index in the northwestern coastline was found to be lowest at 0.379. The highest species diversity of 0.702 was found in the northeastern coastline area. Low diversity in the northwestern area might indicate pollution stresses in that area. The remaining areas still show species richness and no serious indicalion of effects from pollution.
