“…Partitioning of oxygen isotopes between molluscan shells and seawater has historically been assumed to closely approximate in isotopic equilibrium (Witbaard et al, 1994;McConnaughey et al, 1997;Hickson et al, 1999;Schöne et al, 2002;Schöne, 2003). On the other hand more recently Owen et al (2002a, b) showed in a thorough laboratory study a positive deviation from equilibrium ( + 0.6x ) in Pecten maximus.…”

Population dynamics of the queen scallop, Aequipecten opercularis, was investigated in the western English Channel off Roscoff. Annual formation of natural growth rings on the shell surface was validated by stable isotope (y 18 O and y 13 C) analysis. A von Bertalanffy growth function (H t = 58.9 mm . (1Àe À 0.604.(t + 0.235) )) was fitted to size-at-age data of 249 individuals. Annual somatic and gonad production amounted to 19.74 kJ m À 2 and 0.98 kJ m À 2 y À 1 , respectively. Total mortality rate Z was estimated to be 1.716 y À 1 . Net growth efficiencies (ranging from 45% in 1-y-old to 11% in 6-y-old individuals) were in the same range as in other short-lived scallops. Individual growth, however, was distinctly slower in this population than in other A. opercularis populations from similar latitudes, most likely due to a more stressful environment. D

“…Previous studies, mostly on freshwater and land snails, showed large deviations between the true age and measured 14 C age (Fritz and Poplawski 1974;Goodfriend and Hood 1983;Goodfriend 1987;Goodfriend et al 1999;McConnaughey et al 1997;Stott 2002). These deviations are assumed to be related to different 14 C contents in the nutrients, rocks, and water of the shell's habitat.…”

ABSTRACT. We investigated the feasibility of using Melanopsis shells as radiocarbon chronometers of paleolakes and springs in the Jordan Valley, Israel. For this purpose, we analyzed the ,4 C content of aragonite of living Melanopsis shells from different freshwater bodies of the northern Jordan Valley and Lake Kinneret (Sea of Galilee) and compared them to the contemporaneous water values. The Melanopsis shells are in 14 C equilibrium with their habitat waters, allowing to specify a particular reservoir age for various water types. We measured -750 yr for Lake Kinneret, -2300 yr for northern Jordan, -4600 yr for springs in the north Kinneret, and -7200 yr for streams flowing directly from carbonate aquifers. These results were tested and corroborated by analyzing fossil Melanopsis shells of known age, measured on contemporaneous organic matter. We conclude that Melanopsis shells are reliable 14 C chronometers and have the potential to be used as paleohydrological tracers.

“…The δ 13 C may 324 also reflect a kinetic effect. This results in a depletion of both 18 O and 13 C in carbonates 325 (McConnaughey et al, 1997;Owen et al, 2002a). In contrast, metabolic (respiration) effects will be 326 reflected in depletions in shell δ 13 C (McConnaughey and Gillikin, 2008) which are not 327 accompanied by simultaneous changes in shell δ 18 O.…”
