Using the muddy, microtidal York River-Lower Chesapeake Bay (YR-LCB) system as an example, we develop a conceptual framework of organism-sediment-flow interactions along an estuarine gradient. In the turbidity maximum region of the upper estuary, we found evidence for frequent, intense tidally-driven physical disturbance of the seabed. Macrofauna assemblages are impoverished, bioturbation rates are low, and macrofauna influence sediment structure primarily via pelletization. Bivalve biomass… Expand
