“…In Georgia's marshes, ribbed mussels may be limited near subtidal creeks due to intense predation that occurs close to the marsh edge/ subtidal creek ecotone (Lin 1989), most likely by blue crabs (Callinectes sapidus; Fitz and Wiegert 1991;Honig et al 2015), which were also observed in the study's marsh sites (Annis 2021;Carroll et al 2021). Additionally, the lack of ribbed mussels along subtidal creeks may be due to erosion, which has been suggested for some sites in Delaware Bay in the mid-Atlantic USA (Moody and Kreeger 2021). Alternatively, levees of slightly higher elevation are common along subtidal creeks in Georgia marshes (Keunzler 1961).…”

“…Along the northeastern US coast, ribbed mussels are found in thick bands immediately along the marsh edge (Bertness 1984;Bertness and Grosholz 1985;Franz and Tanacredi 1993;Franz 2001;Moody and Kreeger 2021), except for some marshes in the state of New Jersey where mussel densities are low along marsh edges likely due to chronic erosion (Moody and Kreeger 2021). In southeastern US estuaries, ribbed mussels are commonly found in clumps throughout the marsh platform (Lin 1989;Angelini et al 2015).…”

Ribbed mussels, Geukensia demissa, are marsh fauna that are used in coastal management and restoration due to the ecosystem services they provide. Ribbed mussel restoration efforts may be improved with a greater understanding of the environmental drivers of ribbed mussel distribution at multiple spatial scales to predict areas where restoration could be successful. This study sought to estimate the effects of within-marsh (4 m) and landscape (500 m) factors on ribbed mussel distribution. Ribbed mussel densities were surveyed at 11 sites along the coast of Georgia, USA, and overlaid with spatial data for within-marsh factors (elevation, distance to marsh features, slope) as well as landscape factors (percent cover by subtidal creek, forest, and development within a 500-m radius). The distribution model was then validated using three previously unsurveyed marshes and explained 55% of the variance in ribbed mussel abundance. Ribbed mussel abundances and occupancy were most sensitive to changes in within-marsh factors (elevation and distance to subtidal creeks, bodies of water inundated during the full tidal cycle) but were also sensitive to landscape features (percent landcover of forests and development). The highest ribbed mussel densities were found in mid-elevation areas (~ 0.7 m NAVD88), far from subtidal creeks, and in marshes surrounded with forest and development. These results contrast with distributions in the northeastern USA, where ribbed mussels are distributed along subtidal creek banks. This work suggests that restoration may be most effective when focused on appropriate elevations and at locations away from the marsh-creek ecotone.

“…Mussels are thus important biogeochemical couplers of the water column and the marsh bottom, facilitating the exchange of C and N in these ecosystems (Bilkovic et al., 2017; Dame et al., 2002; Kuenzler, 1961). Further, mussel density, both within individual aggregations at the patch scale and across populations of aggregations at the landscape scale, likely modulates the effect of these organisms on C and N processes (Bertness, 1984; Crotty et al., 2023; Moody & Kreeger, 2020; Smith & Frey, 1985). Despite the key, multifaceted importance of these abundant and productive bivalves, the fate of mussel biodepostion as it relates to source‐specific sedimentation, accumulation, and storage of C and N—and how mussel density affects these pathways—in salt marshes has not been explored.…”

Interest in leveraging suspension feeders, such as marine bivalves, to exert top‐down control on organic matter (OM) loading in estuaries is gaining momentum. Not only can these faunal engineers alleviate the consequences of nutrient pollution, but they may also bolster the critical blue carbon services provided by coastal ecosystems—a potential dual, mitigating effect on cultural eutrophication and climate change. Ribbed mussels, Geukensia demissa, offer a useful model for assessing faunally driven carbon (C) and nitrogen (N) processes in these systems and their relationships with faunal density. Combining bulk geochemical analyses with Bayesian stable isotope mixing model frameworks (MixSIAR), we quantified the effect of mussels on the source and amount of organic C and N deposited to the benthic floor (i.e., sedimentation), accumulated in surface sediments, and stored in aboveground Spartina alterniflora in Georgia salt marshes. Relative to areas without mussels, mussel presence shifted the source of deposited and accumulated OM to a more allochthonous makeup; amplified the amount of deposited, but not accumulated, allochthonous and autochthonous OM; and enhanced aboveground storage of C and N. Both sources of OM accumulated in sediments as well as standing stocks of C and N were highly and positively correlated with local mussel density (ind. m−2) but unrelated to neighboring mussel density (ind. ∼25 m−2) in adjacent, non‐mussel areas. This work provides new evidence that suspension feeders, through their faunal engineering activities, can interact powerfully and synergistically with primary producers to enhance the blue carbon services of marshes and counteract coastal eutrophication.
