Mangroves, which are a group of salt tolerant plant community growing in the transition zones of fresh and marine water systems, play an important role as sediment trap. In mangrove ecosystems, litterfall accumulates as organic carbon and nutrients over the sediment surface, where bioturbation profoundly affects the sediment biogeochemistry. Here,...

Oyster breakwater reefs used for coastal protection have shown to enhance local biodiversity. Particularly, macro-invertebrate and fish assemblages can benefit directly from reefs providing structurally complex habitats and indirectly through alteration of soft-sediment environment near the reef areas. To test this hypothesis, a manipulative field...
