Reciprocal Interactions between Bivalve Molluscs and Seagrass: A Review and Meta-Analysis

“…Yet their environmental effects are unlikely to be functionally equivalent because of differences in architecture, chemical composition, flexibility, and trophic level. Seagrasses frequently are managed for protection and restoration (van Katwijk et al 2016), whereas bivalves additionally are targets for aquaculture and fishing (Beninger & Shumway 2018, Bersoza Hern´andez et al 2018. Because the two taxonomic groups often co-occur on soft sediments, interventions on the part of one taxon potentially affect the other, such as facilitation during joint restoration (Gagnon et al 2020).…”

Where land meets sea: Intertidal areas as key‐habitats for sharks and rays

“…The consumptive effects of (local) human populations should also be considered when determining the impact of predators on benthic prey species (Castilla, 1998; Hockey & Bosman, 1986). Traditionally, humans have targeted shellfish and polychaetes on soft‐bottom intertidal flats for consumption and as fishing bait respectively (Beninger, 2019; Watson et al, 2017). de Boer and Longamane (1996) determined that consumption of intertidal prey in Mozambique by both shorebirds and humans was responsible for 18% of the annual biomass removal.…”

“…Traditionally, ecological interactions in the intertidal have been considered from a terrestrial and shorebird perspective, the low‐tide predators of intertidal areas (Beninger, 2019). Shorebirds occupy a central niche in intertidal food webs and are considered one of the most important predator guilds in the intertidal (Kuwae et al, 2012; Mathot et al, 2019).…”

“…These shorebirds can have a generalist feeding strategy, such as sanderlings ( Calidris alba ) and American golden plovers ( Pluvialis dominica , Charadriidae) (Faria et al, 2018; Lourenço et al, 2015), or a more specialist strategy, such as bar‐tailed godwits ( Limosa lapponica , Scolopacidae) and red knots ( Calidris canutus , Scolopacidae) (Van Gils et al, 2012; Zharikov & Skilleter, 2003). Similar to benthic ray species using the intertidal, these shorebirds occupy a meso‐predatory niche in the intertidal food web (Beninger, 2019; Buchanan, 2012; Kuwae et al, 2012), and are in turn preyed upon by bird‐of‐prey species (Page & Whitacre, 1975; Van Den Hout et al, 2008) (Figure 3b).…”

Toward integrated pest management in bivalve aquaculture

“…Bivalve aquaculture is centuries old, with historical records spanning back to Roman oyster farms from the first century AD and North American clam gardens from at least the eleventh century AD. [1][2][3][4] Since these early artisanal practices, bivalve aquaculture has developed into a global industry that generated >15.6 million t of food and $US26.5 billion in revenue in 2017. 5 Three quarters of this production volume comes from four culture taxacupped oysters (Crassostrea spp.…”
