Effects of seagrass overgrazing on sediment erosion and carbon sink capacity: Current understanding and future priorities

Abstract We searched the literature for experimental and observational studies assessing the effects of seagrass overgrazing on erosion of sediment and sedimentary organic carbon (SOC) and found that most studies reported a significant impact, likely caused by a cascading effect (i.e., seagrass shoo...
