The MPB are essential components of soft‐sediment systems, but are often overlooked when assessing coastal ecosystem functionality and service delivery. The MPB are involved in several …
WebThe way in which artificial structures modify sedimentary communities depends on their design and spatial configuration, the characteristics of the abiotic and biotic environment in which they are placed, and the scale of the impact, including area affected and duration (Airoldi et al., 2005; Martin et al., 2005).
