“…For the northern two chronologies, temperature may at least partially be involved. However, it is likely that unmeasured variables such as nutrients and food supply are also likely important [70–72]. Moreover, the environmental variables that influence growth may vary over fine spatial scales.…”

Four chronologies of the bivalve species Glycymeris pilosa have been constructed along a 300 km gradient of the eastern coastal Adriatic Sea, all of which span the common period of 1982–2015. The chronologies are compared to local and remote environmental drivers suspected to influence the biology of the system, including air and seawater temperature, precipitation and freshwater discharge. The Adriatic-Ionian Bimodal Oscillating System (BiOS), a key oceanographic feature quantified by satellite-derived absolute dynamic topography, is also compared to the chronologies. The chronologies at the two southern sites are more strongly influenced by local river discharge, while the two northern chronologies are more strongly influenced by BiOS. These results highlight the broadscale importance of BiOS to the Adriatic system as well as the heterogeneity of nearshore environmental and drivers of growth. These G . pilosa chronologies provide unique multidecadal, continuous, biological time series to better understand the ecology and fine-scale variability of the Adriatic with potential for other shallow, semi-enclosed seas.

“…Eventually the outcome of complex interactions of many factors may cause the apparent morphological similarity, as described in several studies (e.g., Bataller, Boghen, and Burt, 1999;Lohmann and Schöne, 2013;Witbaard, Jansma, and Sass Klaassen, 2003). Local environment forcing such as salinity, temperature, and soft bottom sediment (Von Leesen et al, 2017) and food (Ballesta-Artero et al, 2018) is assumed to be the major reason for the coordination/harmony between populations. Therefore, and owing to an understanding of the underlying mechanisms, soft bottom morphology must be taken into account in future relevant research.…”

Owing to its extremely long life span and occurrence in the entire North Atlantic, the Arctic boreal Arctica islandica has become of particular significance for monitoring the environment, because information on past environmental conditions is archived in morphological and biogeochemical properties of the calcareous shell. To evaluate whether such properties are comparable between different localities, shell and soft body morphometry of six A. islandica populations, Norwegian Coast, Kattegat, Kiel Bay (Baltic), White Sea, German Bight (North Sea), and off NE Iceland, were compared. Discriminant analysis indicated distinct differences between populations, albeit not related to geographical distance, but more likely to local hydrography, bottom morphology, and food regime.

“…islandica DEB parameters, we only included laboratory growth data which were derived at the highest food level (Ballesta-Artero et al, 2018). Medium food level data were not included because growth was not statistically different from growth at the highest food level (Ballesta-Artero et al, 2018).…”

The ocean quahog Arctica islandica is the longest-living mollusk on Earth with a lifespan of at least 500 years. The slow senescence of this bivalve has promoted a great interest in its metabolic strategy. A dynamic energy budget (DEB) model was applied to describe how this species allocates its energy to maintenance, growth, maturation, and reproduction in a variable environment. We studied the relationship between A. islandica growth, lifespan, and food availability at eight different locations in the North Atlantic Ocean. Our results indicate that A. islandica's extreme longevity arises from its low somatic maintenance cost [̇] and low ageing acceleration ℎ̈, but there was not a direct relationship between food availability and lifespan in these A. islandica locations. Monkey Bank (North Sea), Iceland, and Ingøya (northern Norway) had the highest food availability estimates of all the localities but did not have the lowest longevities, in contrast to the theory of caloric restriction.
