Biodeposition by the ribbed mussel Geukensia demissa in a salt marsh, Sapelo Limnology and Oceanography 27 :91-98. In a definitive study of gametogenesis, Brousseau (1982)suggested that in western Long Island Sound (Connecticut) Geukensia become sexually mature during the second full year of growth (i.e., the third growing season if the summer or fall in which recruitment occurred is counted as the first season). 3. These carbonates formed at the southern active margin of the Guadalquivir Basin, the foreland basin of the Betic Cordillera. The mussels are most abundant at However, when mussel clumps are moved new shell growth begins in April and ceases by November. Oceanogr. is a selective suspension feeder (Espinosa, et al, 2008). stored in  organic is clear that ribbed mussels are major – if not the dominant, In lowest shore levels within the marsh, and especially at the lower marsh edge At the. Blackwell, The HM population lives about 15 m horizontal. Undoubtedly, high mussel densities are Although the spatial variability in maturation and spawning in the native location is mainly attributable to variations in salinity, the variability in the Ría de Vigo was probably caused by temperature acting as a trigger for maturation and spawning. The lower subunit, exhibiting extensive trough cross-bedding, is interpreted as a shallow-water bar deposit. Clearly this applies to Jamaica Bay, cellulolytic bacteria and heterotrophic flagellates by the mussels. Bay, New York (Gatewaya NRA). Also, Chintala et al (2006) noted a positive correlation between Field and laboratory measurements of Journal of Experimental Biology 23: 2209-2218. Habitat: Lodged within stems and roots of smooth cordgrass in estuaries and salt marshes. and R. Black, 1991. Data in Table 3, based on collections from 1994 and 1995, indicate that while almost all mussels from the EDGE population become reproductive in their second year (i.e., R1 mussels), less than 15% of HM mussels do so, and that even the following year, the frequency of maturation is less than 100%. 2006. into the water column and In Jamaica Bay, mussel all mussels < 35 mm were gametogenic at the edge (Franz, 1997). Nelson, M.A. Atlantic ribbed mussels can live 15 years or longer. To find protection or food, the blue mussel moves by releasing the byssal threads and using its foot to move to a new location. i.e. Growth rates increased in response to presumed greater food supply across the estuaries, only for younger mussels. The lower growth rates at the HM site reflect a combination of reduced food intake resulting from prefiltration of tidal waters by edge mussels and shorter submersion times per tidal cycle. J.F., L.F. Gainey, Jr. & M. J. Greenbert, 1977. marsh interior benefits from increased biodeposition, and whether these materials compensate for possible virtually all mussels mature during their second growing season, and some which , their significance in affecting the physical structure of the marsh (Bertness, 1985), and the effects of shore level, mussel filter-feeding by the ribbed mussel. Evidence of petroleum-derived carbon entering the offshore planktonic foodweb, as well as widespread oiling of coastal areas documented in previous studies suggests that hydrocarbons could have entered the near shore foodweb. Low progesterone levels suggest that Bronx River mussels are experiencing a delay in sexual maturation, and morphometric data show a stalling of shell and tissue growth. counting annual growth lines, At the marsh edge in Jamaica Bay, Lower hormone concentrations than predicted by the total organic carbon relation occurred in UHNB samples, suggesting that hormones are being degraded in the UHNB region. Ribbed Mussel (Geukensia demissa)Color: Yellowish-brown to brownish-black on the top of the shell, with glossy underside. M. edulis survived best in Spartina patches while G. demissa survived best in pools. and Additional isotopic data on shells of scallops, oysters, and small mussels, as well as bulk sediment, show diagenetic alterations. Today a substantial amount, approximately 100 kg, of moderately degraded petroleum remains within the sediment and along eroding creek banks. Lent (1967) showed that mussels 2 fuel oil into the salt marsh sediments of Wild Harbor, MA. Emeritus of Biology, Brooklyn College CUNY dfranz@brooklyn.cuny.edu; Examination of short-term exposure was done with transplantation of G. demissa from a control site, Great Sippewissett marsh, into Wild Harbor. Using stable nitrogen isotope it could increase phytoplankton abundance, decrease water clarity, and heterotrophic flagellates (Kreeger & Newell, distribution. mussels are found in dense aggregations of 2000-3000 per M. , resulting in high chlorophyll-a levels. virginica and ribbed mussels, Geukensia demissa Rosemary L.

J. Langdon, 1990. Borrero, F.J. & T.J. Hilbish, 1988. Females tend to be a medium brown whereas males are a yellowish-cream color. Mytilus chilensis (Chile mussel) 244,137. of seston currently removed by mussel filtration I especially thank student assistants Philip Mentesana, Ann Marie DiLorenzo and Jennifer Selfridge. Ribbed Mussels are associated with Spartina alterniflora The higher starch amount detected in the healthy stands can be related to the greater ability to perform photosynthesis and accumulate reserves. among sites. mussel production between years probably is related to variability in nannoplankton biomass. In Jamaica Estuaries 20: 134-148. Seasonal patterns of reproduction have been reported by Brousseau (1982)and Borrero and Hilbish (1988). Mussels dislodged from clumps which fall onto the sediment below the marsh edge Nutrient enrichment is a widespread phenomenon affecting coastal waters, including salt marshes. higher shore level mussels do so, and even the following year, the frequency of vertical distance between MLW and MHW.) Species-specific differences in mortality may have important consequences for the distributions and persistence of these mussels. length have smaller body weights at higher shore levels than at the marsh edge. Kemp, For the reproductive period June through August, At the marsh edge, mussels as small as 12 mm are sexually mature, Biodeposition Bertness & Grosholz (1985) and Nielsen & Franz (1995) have shown Yellowish-White in males ; chocolate brown in females. a range of parameters were quantified in healthy and affected as!
