“…The association that we found between the mussel and S. foliosa has also been well documented in salt-marshes on the Atlantic coast of North America, where G. demissa attaches to the roots of S. alterniflora by byssal threads (Bertness 1980(Bertness , 1984Fell et al 1982). Cordgrass production increases growth and reproduction of the mussel, and the presence of the mussel increases production of the cordgrass, which results in increased marsh net primary production and stability (Bertness 1984).…”

Introduced populations of Guekensia demissa occur on the west coast of North America. They have been reported in San Francisco Bay, four southern California wetlands, and in Estero de Punta Banda (EPB), Baja California Norte, Mexico. We randomly sampled benthic invertebrates in four habitat types within EPB: marsh, channel, mudflat and pan. Geukensia demissa was the most abundant bivalve in the wetland at EPB. It was significantly associated with the native cordgrass, Spartina foliosa, and occurred at higher average densities in vegetated marsh sites (24/m 2 ) and Spartina-dominated tidal channels (35/m 2 ), compared to mudflat (0/m 2 ), and pan (0/m 2 ) sites. We estimated that the total biomass of this invader was over four times that of the next most abundant bivalve, Tagelus spp., in EPB. We examined G. demissa for parasites and found that only a few native parasites colonized this introduced host at very low prevalences and intensities. We performed bird surveys to determine the habitat overlap and potential impact of this mussel on the EPB population of light-footed clapper rails (Rallus longirostrus levipes), an endangered species in the United States. The high abundance of G. demissa in EPB, its presence in clapper rail habitat, and its known effects on salt marsh habitat in it's native range, warrant further investigations of the impact of this invader in EPB and elsewhere.

“…In Kostka et al (2022), similar numbers of U. pugnax burrows were observed in unvegetated and vegetated sediments. Fell et al (1982) found that the highest densities of U. pugnax occurred in bare areas alongside a mosquito ditch compared to vegetated habitat. Johnson (2014) observed that U. pugnax was rarely found in vegetated areas as opposed to non-vegetated habitats and Luk and Zajac (2013) stated that the highest abundances of U. pugnax were associated with bare ground patches in salt marshes of Long Island Sound.…”

Does loss of salt marsh vegetation caused by a native grapsid crab improve habitat suitability for the Atlantic mud fiddler ( Uca pugnax)?

A B S T R A C TThe abundance of Uca pugnax (Smith, 1870), the Atlantic marsh fiddler crab, has been shown to be both positively and negatively related to vegetation cover in a number of previous studies. In Cape Cod National Seashore marsh (Massachusetts, USA), it appears that the abundance of U. pugnax is high in areas where salt marsh vegetation has died back as a result of Sesarma reticulatum (Say, 1817), the purple marsh crab, activity compared with healthy, vegetated areas. However, this relationship has not been experimentally tested. In this study U. pugnax burrows were enumerated in treatments consisting of 1) vegetation and sediment removal, 2) naturally occurring dieback areas where vegetation is absent, 3) vegetation removal by cutting, and 4) intact vegetation. The results indicate that U. pugnax may prefer open, unvegetated habitats with softer substrates. The proliferation of U. pugnax in open areas could therefore be facilitated by S. reticulatum, which has consequences for a number of other ecosystem processes.

Population ecology of the gulf ribbed mussel across a salinity gradient: recruitment, growth and density

Ecosphere 6(11):226. http://dx.doi.org/10.1890/ES14-00499.1Abstract. Benthic intertidal bivalves play an essential role in estuarine ecosystems by contributing to habitat provision, water filtration, and promoting productivity. As such, changes that impact population distributions and persistence of local bivalve populations may have large ecosystem level consequences. Recruitment, growth, mortality, population size structure and density of the gulf coast ribbed mussel, Geukensia granosissima, were examined across a salinity gradient in southeastern Louisiana. Data were collected along 100-m transects at interior and edge marsh plots located at duplicate sites in upper (salinity ;4 psu), central (salinity ;8 psu) and lower (salinity ;15 psu) Barataria Bay, Louisiana, U.S.A. Growth, mortality and recruitment were measured in established plots from April through November 2012. Mussel densities were greatest within the middle bay (salinity ;8) regardless of flooding regime, but strongly associated with highest stem densities of Juncus roemerianus vegetation. Mussel recruitment, growth, size and survival were significantly higher at mid and high salinity marsh edge sites as compared to all interior marsh and low salinity sites. The observed patterns of density, growth and mortality in Barataria Bay may reflect detrital food resource availability, host vegetation community distribution along the salinity gradient, salinity tolerance of the mussel, and reduced predation at higher salinity edge sites.
