Effect of replanted mangrove size on gastropods community structure, abundance and morphometrics / Wan Mohd Nabil Mohd Nazri

This study was conducted to determine the gastropod community, distribution and shell morphometrics of different replanted mangroves size. Increased replanting mangrove activities helps to understand functions of these type of forest especially related to gastropods communities. Gastropods can be in...

Dorani (SHD), intermediate mangrove represented by Kg. Sg. Tiram (KST) and large mangrove at Kg. Dato Hormat (KDH) at the west coast of Peninsular Malaysia. The line transect with quadrat method was employed to sample the gastropods. 4321 individuals representing 30 taxa from 8 families were recorded from the study sites. 13 taxa were recorded at small, 25 taxa at intermediate and 20 taxa at large mangrove site. Small mangrove recorded highest density (total=5.47 no/m²) followed by intermediate (total=4.3840 no/m²) and large mangrove (total=1.28 no/m²). Among taxa, Littoria scabra (total=4.29 no/m2) and Pirenella cingulata (total = 4.08 no/m2) recorded high density from the study sites. Intermediate mangrove recorded the highest biomass (35.73 g/m2) followed by small (3.26 g/m 2) and large mangrove (3.01 g/m2). Among taxa, higher biomass was recorded for Telescopium telescopium (24.29 g/m2) followed by Telescopium mauritsi (4.76 g/m2) and P. cingulata (4.22 g/m2). With respect to diversity, Intermediate site recorded the highest (D) (1.5) followed by small (0.77) and large site (0.75); intermediate recorded the highest (H’) (1.24) followed by small (0.69) and large site (0.68); Large site recorded the highest (E) (0.74) followed by intermediate (0.59) and small site (0.56).
