“…The longest-lived G. glycymeris specimen from the Bay of Brest was only 70 years old (Featherstone et al, 2017) and from the Mediterranean no Glycymeris spp. specimen older than 65 years was described so far (Peharda et al, 2016). All aforementioned studies support the hypothesis that there is a latitudinal gradient in G. glycymeris longevity (Reynolds et al, 2013) in agreement with the same trend observed in bivalve life spans on a larger scale (Moss et al, 2016).…”

“…Rather, a link between enhanced shell growth and riverine nutrient input was put forward (Featherstone et al, 2017). Similarly, increased annual shell growth of G. pilosa was reported to correlate positively with precipitation (and the resulting enhancement in primary production) and negatively with summer SST from the Adriatic (Peharda et al, 2016).…”

Despite the positive results obtained using saltwater clam Glycymeris spp. for palaeoenvironmental reconstructions in the extratropical North Atlantic domain, this potential of the species has not been investigated in the subtropical North Atlantic region. The aim of this study was to investigate the driving factors for shell growth in Glycymeris bivalves by analyzing growth patterns of G. vangentsumi specimens from an environment that is exposed to relatively minor seasonal contrast in terms of temperature compared to mid/high latitudes around the Madeira Islands. The populations studied comprised a group of sub-fossil shells (n = 58) collected near the Desertas Islands, Madeira, in 2014, in a depth range of 80-160 m, together with two live-caught specimens. The shells collected alive were relatively young (<37 years), while the ontogenetic ages of the sub-fossil shells proved to be high (up to 154 years). Compared to those collected at greater depths, the average growth rate of the shells in the shallower environment was higher in the first 4 years. Subsets of the Madeira (n = 16) samples could be arranged into a robust site chronology covering the 1950-2012 period, and these were used to explore shell growth responses to environmental parameters. The composite chronology displayed a negative correlation (r < −0.58, p < 0.01) with the January-April sea surface temperature (SST) around Madeira and a positive correlation (r = 0.52, p < 0.05) with the March sea surface chlorophyll concentration data of the region, from 1998 to 2012. The results presented here suggest that at this southern collection site, lower water temperature was not a directly limiting environmental variable, and other external environmental effects may exert stronger control on shell growth. These include the effect of late winter ocean mixing on the formation of the deep chlorophyll maximum.

“…Glycymeris longior longevity (up to 69 years) is similar to the glycymerids from mid-latitudes of the Northern Hemisphere. Similar longevities were reported for G. glycymeris reported from the Irish Sea (68 years) [15], for G. glycymeris from the NE Atlantic (70 years) [49] and for G. pilosa from the Adriatic Sea (69 years) [45]. Glycymeris longior is part of the group of the most long-lived species of Argentine Sea.…”

“…Growth in Glycymeris genus seems to be driven by a complex combination of environmental factors, especially for populations that occur in shallow coasts with highly variable conditions [45]. Growth of G. pilosa was positively associated with precipitation which increases coastal runoff and nutrient discharge and results in enhancement of primary production [45]. Growth of G. vanhengstumi from NE Atlantic depends on the surface primary production conditioned by the upward transport of the nutrients fertilizing the photic zone, which is driven by the late-winter cooling of the sea surface and ocean mixing [41].…”

Age and growth of Glycymeris longior (Sowerby, 1832) clam at the southern edge of its distribution (Argentine Sea)

Even though Glycymeris longior is a clam widely distributed in the SW Atlantic Ocean, little is known about its biology and life history. The present study assessed the periodicity of the internal growth increments of G. longior using thin shell sections. Each internal growth increment was composed of two alternating bands: a translucent band (lightcoloured when viewed with transmitted light) and an opaque band (dark-coloured). Annual formation for each pair of bands was demonstrated. The formation of the annual growth increments was synchronous among individuals. Growth was determined from live clams collected at El Sótano, Argentine Sea (age range = 29 to 69 years). According to the growth model, G. longior grows fast during the first 5 years of life and then growth becomes slower in later years; individuals reached 50% and 90% of maximum size at 5 and 13 years of age, respectively. High variability was found in shell height for the first 10 years: differences up to 5-7 mm among individuals were registered for the first 2 years of age, and up to 11 mm between the ages of 3 and 9 years. The growth performance index phi-prime (φ′) and the index of growth performance (P) of G. longior were compared with those of other Glycymeris species. Our results indicate that G. longior is a slow-growing species with a long lifespan (maximum longevity = 69 years).

The impact of climate warming on coastal benthic fauna is already observed, but forecasting their long‐term fate remains challenging. This study uses δ18Oshell data of specimens of five bivalve species collected at six locations and results from kilometer‐scale atmosphere–ocean climate model for the time intervals of 1987–2017 and 2070–2100, to estimate changes in bivalve growth phenology. All species will benefit from climate warming during winter, experiencing a longer growing season than currently. The growth of Aequipecten opercularis, Flexopecten glaber, and Pecten jacobaeus will decrease in summer, resulting in up to 3 months of reduced growth per year. Glycymeris pilosa and Venus verrucosa in the southern Adriatic Sea will be more affected than those in the north, with up to 4 months longer annual growth. These findings can inform adaptation plans for bivalve management in the Adriatic Sea but also in areas where the studied species are present.
