Última Trophic interactions in the coastal ecosystem of Sri Lanka: An ECOPATH preliminary approach ArchiMer Haputhantri, S; Villanueva, Ching-maria; Moreau, J. This study attempts to assemble and summarize existing information in order to build a general representation of the trophic interactions within the shallow coastal ecosystem of Sri Lanka. A multispecific ecosystem-based approach on trophic relationships and their possible variations was performed using ECOPATH. Thirty-nine functional groups were considered representing all trophic levels in the food web. Time-dynamic simulation was carried out using the ECOSIM routine to evaluate the impact of the 1998 El Nino event on key functional groups. Results show that the time needed for any impacted functional group to recover to its initial abundance increased with the trophic level. Two time-series data sets derived from commercial catch and effort statistics...
