WebNov 25, 2024 · The heterogeneous topography of continental margins can influence patterns of resource availability and biodiversity in deep-sea sediments, potentially altering ecosystem functioning (e.g., organic matter remineralization). Noting a lack of studies that address the latter, we contrasted spatial patterns and drivers of benthic nutrient fluxes … WebFeb 13, 2002 · In a mangrove estuary in northern Taiwan, spatial patterns of organic matter flows from primary producers and detritus derived from vascular plants to macrofaunal polychaetes and crabs were examined using stable isotopes of carbon and sulfur.
