Composition of Harpacticoida (Crustacea: Copepoda) during land reclamation activity in seagrass area of Sungai Pulai, Malaysia

Sungai Pulai is one of the largest areas for riverine mangroves which associated with other important ecosystem, the seagrass bed and mud flat located in the Tebrau Straits of Johor. The nearby area is experienced rapid development activities including land reclamation. This study is carried out to...

This study is carried out to investigate the composition of copepods particularly the Harpacticoida group in the seagrass bed continuously exposed to such land activities.

Result revealed that there is a significant different for Porcellidiidae density (F=5.512, p=0.002) between all harpacticoid copepod family member in all station except with Diosaccidae in the vegetation area. Overall, 2-Way Anova by using Duncan test showed the density of harpacticoid copepods in vegetation area is highly significant compared to non-vegetation area (F=4.512, p=0.005). In vegetation area, Pearson’s Correlation analysis summarized that Cannuellidae has strong correlation with Total Organic Matter, TOM (R=0.864) if compared to other families. In first sampling, family Porcellidiidae showed high significant correlation towards mean grain size and sorting condition of sediment which is R=1.000, p=0.018 and R=-0.997,p=0.049 respectively.

Porcellidiidae which is known as obligate phytal species does not affected by the amount of TOM but with sediment characteristic along with Longipedidae and Tisbidae, which indicate their composition could be easily affected by the change of sediment in the area. 2018 Conference or Workshop Item NonPeerReviewed application/pdf en http://irep.iium.edu.my/76696/1/Jsps%20poster.pdf application/pdf en http://irep.iium.edu.my/76696/13/76696%20abstract.pdf Kassim, Zaleha and Nordin, Amira Syahidah and Ismail, Ahmad (2018) Composition of Harpacticoida (Crustacea: Copepoda) during land reclamation activity in seagrass area of Sungai Pulai, Malaysia.
