“…Similarly to gastropod devoted studies, the main fields of application of GM-based studies of bivalve mollusks are: identification of intraspecific groups (Costa et al, 2008(Costa et al, , 2010Funk and Reckendorfer, 2008;Márquez et al, 2010;Rufino et al, 2013;Boretto et al, 2014), assessment of the impact of environmental factors (Innes and Bates, 1999;Krapivka et al, 2007;Funk and Reckendorfer, 2008;Márquez et al, 2010;Boretto et al, 2014;Telesca et al, 2018) and investigating ontogenetic and evolutionary changes (Serb et al, 2011;Boretto et al, 2014;Alvarez and Pérez, 2016). Funk and Reckendorfer (2008) addressed the morphological variability of Pisidium subtruncatum shells.…”

“…The study revealed that morphological distances between two species were higher than between populations of the same species. Finally, the temporal variation of the striped clam shell was analyzed by Boretto et al (2014). Using landmark-based methods and EFA they investigated the changes of the striped clam shell shape from Pleistocene to the present day.…”

“…In the studies of bivalve shells, geometric morphometrics are a routine tool for the shape analysis. Due to the fact that, unlike other recording structures, shells of the taxon usually have rounded outlines, EFA appears to be the most common and convenient method of analysis (Innes and Bates, 1999;Krapivka et al, 2007;Funk and Reckendorfer, 2008;Márquez et al, 2010;Rufino et al, 2013;Boretto et al, 2014;Alvarez and Pérez, 2016;Telesca et al, 2018). In cases where the use of EFA is limited, application of landmarks can provide accurate discrimination (Márquez et al, 2010;Rufino et al, 2013;Boretto et al, 2014).…”

Morphometric analysis of biogenic recording structures within marine organisms has applications in stock assessment, taxonomics, and ecomorphological studies, with shape variation markedly influenced by both genetics and the surrounding environment. Geometric morphometrics (GM) is an alternative approach to the “traditional” method of collecting linear measurements and applying multivariate statistical methods to these data. Landmark- and outline-based GM methods are suggested to have several advantages over the “traditional” method. Due to the increasing popularity of GM methods in the modern literature, this chapter first compares different morphometric techniques, and then reviews the methods applied to recording structures, with a focus on GM outline-based analyses. It is clear that outline methods have become a popular method of analysis for structures such as otoliths, particularly for the purpose of distinguishing between population components. However, for other structures such as beaks this technique is only in its early stages of application and is more difficult to apply but shows great promise for future studies. The advantages of using a holistic approach, incorporating several techniques including outline analysis for stock identification purposes is discussed.

“…Arctica islandica occurs at depths down to 482 m (Nicol, 1951), although it is commonly found between 10 and 280 m (Kennish and Lutz, 1995;Merrill and Ropes, 1969;Rowell and Chaisson, 1983;Thompson, Jones, and Ropes, 1980). There is considerable knowledge on anatomy (Boretto et al, 2014;Morton, 2011;Palmer, 1979), behaviour (Taylor, 1976), ecophysiology (Ballesta-Artero et al, 2017;Bayne, 1971;Tschischka, Abele, and Portner, 2000), and population dynamics (Brey et al, 1990;Murawski, Ropes, and Serchuk, 1982;Thompson, Jones, and Ropes, 1980), the latter being particularly interesting for the management of commercial fisheries of A. islandica. Recently, longevity of A. islandica was the focus of interest in this species: on the one hand, physiologists study the cellular mechanisms of ageing (Abele et al, 2008;Strahl et al, 2007); on the other hand climatologists and ecologists are interested in the calcareous archive provided by the shell that contains morphological and biogeochemical information on past environmental conditions (Bonitz et al, 2018;Lohmann and Schöne, 2013;Marali and Schöne, 2015;Milano et al, 2017).…”

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.

“…Some previous studies have registered morphological variations in modern and fossil specimens of the same species by analysing the size and shape of their preserved remains (Stanley & Yang, 1987; Crampton & Maxwell, 2000; Gordillo et al , 2011; Boretto et al , 2014).…”

Form changes inAmiantis purpurata(Bivalvia, Veneridae) shells over the past 100,000 years in North Patagonia (Argentina)

Amiantis purpurata shells from the San Matías Gulf (SMG) were analysed in order to compare both morphology and size throughout the late Quaternary in relation to environmental changes. Shells from modern beaches, Holocene marine assemblages (late Holocene, 3630 ± 100 years bp) and interglacial Pleistocene marine assemblages (MIS 5, 100 ka years bp) were studied by measuring the height and length, and using the elliptic Fourier analysis (EFA) to take an outline contour. The Pleistocene shells were smaller, more elliptical and with a deeper lunule than the Holocene and modern ones. No significant differences were recorded in the allometry index throughout the late Quaternary. The variation in size and shape of the A. purpurata shells could be related to the phenotypic plasticity of this species as a response to the environmental changes registered in the SMG during the Quaternary. These changes include variations in sea surface temperatures, salinities and substrates, and also water circulation changes, which would have modified nutrient availability. Morphological changes imply burrowing activity, mechanical stability, nutrient uptake and defence response to predation.
