Phytoplankton diversity and abundance in Panguil Bay, Northwestern Mindanao, Philippines in relation to some physical and chemical characteristics of the water
Journal Title: Advances in Environmental Sciences - International Journal of the Bioflux Society - Year 2012, Vol 4, Issue 3
Abstract
Phytoplankton composition diversity, abundance and their relation with the physico-chemical parameters of the waters in two coastal sites in Panguil Bay, Philippines were compared. A total of 93 species belonging to four major groups (diatoms, dinoflagellates, silicoflagellates and cyanobacteria) were identified, with the diatoms being the chief component of the phytoplankton. Using several diversity indices, results showed minimal differences in the phytoplankton species between the two sites. The results of NPMANOVA revealed significant differences (p<0.05) in phytoplankton relative abundancebetween sites and within sites between months. These differences were attributed to variations in the physico-chemical characteristics of the water as reflected from the results of Canonical Correspondence Analysis (CCA). Since results of the study reflect the importance of physical and chemical factors of the water on the phytoplankton community structure in Panguil Bay, it is suggested that changes in these factors, may it be due to natural or anthropogenic sources, may lead to impacts or changes in phytoplankton dynamics.
