Utilization of dual stable isotope markers (δ13C and δ15N) to determine trophic structure in aquatic environment of Malaysian peat swamp forest

This study was conducted to develop a preliminary food web model of aquatic environment at the North Selangor Peat Swamp Forest (NSPSF) using stable isotope markers (δ13C and δ15N). The samples were collected from two selected points of peat swamp area representing disturbed and undisturbed areas. S...
