“…As a consequence, proportionally more shell would have been laid with lower elemental ratios to calcium over our two-month study, resulting in the negative correlation that we observed. Although such an age effect has not been observed in M. arenaria, previous studies of molluscs have reported decreased elemental incorporation with size (Dodd, 1965;Hirao et al, 1994;Arai et al, 2003). Bold F statistics are significant and indicate that slopes are different among tanks, making it invalid to pool data.…”

The chemical composition of bivalve shells can reflect that of their environment, making them useful indicators of climate, pollution, and ecosystem changes. However, biological factors can also influence chemical properties of biogenic carbonate. Understanding how these factors affect chemical incorporation is essential for studies that use elemental chemistry of carbonates as indicators of environmental parameters. This study examined the effects of bivalve shell growth rate and age on the incorporation of elements into juvenile softshell clams, Mya arenaria. Although previous studies have explored the effects of these two biological factors, reports have differed depending on species and environmental conditions. In addition, none of the previous studies have examined growth rate and age in the same species and within the same study. We reared clams in controlled laboratory conditions and used solution-based inductively coupled plasma mass spectrometry (ICP-MS) analysis to explore whether growth rate affects elemental incorporation into shell. Growth rate was negatively correlated with Mg, Mn, and Ba shell concentration, possibly due to increased discrimination ability with size. The relationship between growth rate and Pb and Sr was unresolved. To determine age effects on incorporation, we used laser ablation ICP-MS to measure changes in chemical composition across shells of individual clams. Age affected incorporation of Mn, Sr, and Ba within the juvenile shell, primarily due to significantly different elemental composition of early shell material compared to shell accreted later in life. Variability in shell composition increased closer to the umbo (hinge), which may be the result of methodology or may indicate an increased ability with age to discriminate against ions that are not calcium or carbonate. The effects of age and growth rate on elemental incorporation have the potential to bias data interpretation and should be considered in any biogeochemical study that uses bivalves as environmental indicators.

“…Bivalve shell is believed to be grown in annual increments (Brouseau 1978;MacDonald and Thomas 1980;Tanaka and Tanaka 1980) which allows the analysis of one annual growth increment which represents a time-integrated average of the conditions experienced by the organism during its active growing season (Arai et al 2003). In the mean time, the metals found in the shells could be explained on the basis that some trace metals are incorporated into the shells of the gastropod through substitution of the calcium ions in the crystalline phase of the shell or are associated with the organic matrix of the shell (Foster and Chacko 1995;Yap et al 2003d).…”

The concentrations of Cd, Cu, Fe, Ni, Pb and Zn in the different parts of six bivalves species were determined. From the study conducted, it was found that the byssus of Perna viridis, Scpharca broughtonii and Trisidos kiyonoi; the gill of Polymesoda erosa and Donax faba; and the foot of Gelonia expansa were highly accumulative of Cu. High levels of Cd were found in the gills of Scpharca broughtonii and the byssus of Trisidos kiyonoi; and also the shells of the four remaining bivalve species. As for Zn, the mantles of P. erosa and T. kiyonoi, and the gills of D. faba, G. expansa and S. broughtonii were highly accumulative of Zn. High level of Pb and Ni were found in the shells of all the species which indicated that the shells of the bivalves were highly accumulative of Pb and Ni. Elevated levels of Fe however were found in the different parts of the bivalve since Fe is an essential metal in metabolic activities and an abundant element in nature. The heavy metals in the total tissues and the different soft tissues of the bivalves were compared with the maximum permissible limits set by five different countries. From the comparison, it was found that most of the bivalves contained metal concentrations which were below the maximum permissible limits and should pose no toxicological risk to consumers.

The chemical composition of biogenic carbonate has great potential to serve as a natural tag in studies of marine population connectivity. Yet the degree to which carbonate chemistry reflects ambient water composition may be influenced by environmental parameters, physiology, and uptake kinetics. We explored the effects of temperature and salinity on the uptake of elements into shells of larval and juvenile softshell clams Mya arenaria. Clams were reared under controlled conditions using combinations of temperatures (15, 20, and 24°C) and salinities (22 and 30 ‰) commonly encountered in their natural habitat. We analyzed the ratios of a suite of elements (Mg, Mn, Sr, Ba and Pb) to Ca in seawater and shells using solution-based inductively coupled plasma-mass spectrometry (ICP-MS). Elemental ratios were translated into discrimination coefficients (D element ) to account for water chemistry variability among treatments. For larval shell, we found that D Mn was lower in the low-temperature treatment than at higher temperatures, had mixed results for correlations with salinity, and exhibited an interactive effect between salinity and temperature. We also found that D Ba of larval shell was higher in the 15°C treatment than at the other 2 temperatures. In juvenile shell, we found a temperature effect for D Mn , however the exact relationship was unclear because D Mn was higher in the mid-temperature treatment than either the low-or high-temperature treatments. D Sr was negatively correlated with salinity in juveniles, with evidence of an interactive effect for temperature and salinity. D Ba and D Pb were both higher in juveniles in the low-temperature treatment than in the 2 higher temperatures. When discrimination coefficients significantly differed based on ANOVA, we used post hoc comparisons to further explore the effects of temperature and salinity. Correlation analyses showed that uptake differed significantly between larval and juvenile M. arenaria shell for all elements, with no predictable relationship in shell uptake between the 2 stages except for D Ba . All of the elements examined in this study have the potential to be useful in tagging studies where geographic variability in temperature, salinity or elemental concentrations exists, although caution should be used to ensure any biological interactions with these variables are accounted for in data interpretation.KEY WORDS: Mya arenaria · Bivalve shell · Elemental uptake · Discrimination coefficients · Temperature · Salinity · Larva · Biogenic carbonate Resale or republication not permitted without written consent of the publisherMar Ecol Prog Ser 370: [155][156][157][158][159][160][161][162][163][164][165][166][167][168][169] 2008 (and therefore its role in connectivity) is challenging due to small larval sizes, rapid dilution rates, and high larval mortality (Thorson 1950(Thorson , 1966.In recent years, the use of artificial and natural tags to track marine larvae has been explored (e.g. Thorrold et al. 2002, Levin 2006.
