| Summary: | The coastal environment of the Johor Strait is gradually being altered, thus degrading the ecosystem's health. The present study was conducted to determine the food web in mangrove-mudflat ecosystem in vicinity to Sungai Pulai estuary as revealed by stable isotope analysis. A wide range of biota and sediments were collected and analyzed for δ 13 C and δ 15 N isotopic ratios. Results showed δ 13 C and δ 15 N values were ranged between-14‰ to-31‰ and 2.5‰ to 17.5‰, respectively. These data revealed that there are four trophic levels (primary producers up to tertiary consumers) that exist within the mangrove-mudflat ecosystem. Hence, a stable isotope analysis could be used to verify trophic structure in tropical mangrove ecosystem. |
