“…In contrast, the sagittal otoliths have a higher degree of dissimilarity within taxonomic groups (e.g. Nolf 1985;Volpedo and Echeverría 2000;Campana 2004;Tuset et al 2008), which is why the MD did not show a relationship with average taxonomic distinctness. The morphological convergence in some characteristics (e.g.…”

“…Although it is unknown how the type of sulcus actually affects sound transduction, the properties of the sulcus are species specific (Nolf 1985;Gauldie 1988;Torres et al 2000;Reichenbacher and Reichard 2014). Thus, the cluster analysis indicated that, for example, mullets (Mugiliformes), croakers, hakes, cod (Gadiformes) or dories (Zeiformes) were isolated because they have a special type of sulcus (Tuset et al 2008). Therefore, joint analysis of otolith outline and sulcus shape is a powerful tool for the study of fish assemblages.…”

“…However, the otolith morphospace showed a different spatial variability for some species. Scophthalmids and soleids (flatfish) appeared separated in the otolith morphospace because their otoliths are mainly differ in the type of opening of the sulcus, which is ostial in scophthalmids and pseudo-ostial or mesial in soleids (Tuset et al 2008). Scophthalmids feed on highly mobile prey and these foraging techniques require strong visual and hearing abilities, whereas soleids, with a smaller mouth, feed on slow-moving prey (Guedes and Araújo 2008).…”

“…This assumption is based on two reasons: (1) the contour is defined from few points, providing an otolith pattern in lesser detail in relation to other mathematical procedures; and (2) the shape of the sulcus acusticus is consistent within species (Torres et al 2000;Tuset et al 2008). Therefore, the otolith shape obtained for each species is a consensus representation obtained using a morphological geometric method, which can be applied for any general research (such as the present study), but not for specific studies, such as stock identification.…”

Abstract.To check the suitability of otoliths for measuring biodiversity, the contour and shape of the sulcus acusticus of sagittal otoliths were described using geometric morphological analysis. Thirteen and fourteen points were used to define these structures respectively. Three current coastal fish assemblages of the north-western Mediterranean were selected for the present study. The results demonstrate that the relative warps generated in the geometric analysis explained both characteristics related to contour and the otolith sulcus. A comparative study with body fish shape using morphospaces and clusters revealed that otolith shape is a better variable for explaining the ecological structure of a fish assemblage. Moreover, three morphological indices (morphological richness (MR), morphological disparity and the morphogeometric index) were estimated from relative warps of otoliths and were compared with ecological, taxonomic, functional and morphological (from body shape) indices. MR increased with functional diversity and average taxonomic distinctness, reflecting the ecological and taxonomic character of otolith morphology. These findings suggest that otoliths could be a useful tool for studying the diversity of present and past fish assemblages.
