Development of human impact on suspension-feeding bivalves in coastal soft-bottom ecosystems
Suspension-feeding bivalves often may occur in large concentrations ('beds') on tidal flats. This makes them attractive for human consumers and the archaeological record shows collection of bivalves by coastal populations already tens of thousands of years ago. In modem time human interfer...
