Abstract

Mangrove forests are known to provide important ecosystem goods and services such as nursery areas for several important aquatic species, and a variety of food for several animal groups,  including gastropods. This research was conducted from September 2016 - August 2017. The aim of the research was to determine the spatial and temporal pattern distribution of C. djadjariensis based on mangrove zone, environmental characteristics, and organic materials. The gastropod samples were taken by using a square transect sized 25 cm x  25 cm.  The spatial analyses were done by using transect 10 m x 10 m. The gastropod and environmental characteristics were analyzed using Principal Component Analysis (PCA). The total of gastropod C. djadjariensis was 528 ind./m2. The result of high significant was organic matter (0.92), total phosphorus (0.92), dust (0.86), clay (0.86), temperature (0.69). The distribution and abundance are affected by the availability of food,  water condition, and zone in the mangrove.
