The influence of benthic organisms on the turnover rate of leaf litter is considered a vital factor to regulate the dynamic of soil organic carbon (SOC) in mangroves. Among the benthic organisms, sesearmids (i.e. Neosarmatium smithi, Episesarma versicolor and Perisesarma cf. guttatum) contribute evidently to this process but the machanisms are poorly known. To quantify this interaction the current study was carried out in a southern mangrove patch of Sri Lanka. The amount of SOC among the sites ranged from 8.20 ± 2.05 to 18.52 ± 4.63 kgm−2. The ecological zonations (e.g. disturbed and least disturbed) due to land-use changes and pollution events influence the variations of physico-chemical parameters among the habitats. Accordingly, the SOC sedimentation was increased with high crab density and biomass in the least disturbed sites. The stem density of mangroves showed a positive linear relationship with mean crab biomass; representing the mangroves as habitat providers. High amounts of mangrove propagules in crab burrows provide substantial inputs to the standing stock and finally to the SOC sedimentation process. [ABSTRACT FROM AUTHOR] |
