“…Besides, it has been demonstrated that the morphological analyses present high correlations with functional diversity analyses performed in these communities (Farré et al, 2013). Thus, the power of this morphological approach lies in its ability to supply information related with ecological and functional roles of species (Azzurro et al, 2014;Cooper and Westneat, 2009;Costa and Cataudella, 2007;Friedman, 2010;Kassam et al, 2003;Wainwright et al, 2004), which are key factors that help to improve the knowledge about the structure and diversity of communities (Farré et al, 2013;Lombarte et al, 2012;McClain et al, 2004;Montaña and Winemiller, 2010;Tuset et al, 2014;Willis et al, 2005). Therefore, our results support that the analysis of the morphology of species represents a useful tool in studies of description of community structure, and reinforce its use as an alternative or complement with functional or traditional ecological diversity analyses.…”

“…The analysis of species morphology was realized using morphometric data obtained by the selection of 27 landmarks and semilandmarks (Fig. 2a) that describe the shape of each species from standardized images of the left side (Azzurro et al, 2014;Farré et al, 2013;Tuset et al, 2014). A consensus image of each species was used (Recasens et al, 2006) and in order to consider the abundance of species in the analysis, for each species it was calculated its proportion in % respect total abundance of each community.…”

Morphological characters of species are essential for assessing the functional structure of a fish assemblage, since differences between them, for example in body shape, are related to many functional and ecological traits (e.g., swimming, search for food, striking and capturing prey, evading predators, spawning). Globally, tidal flats are relevant to fish assemblages by offering feeding, refuge, and reproduction grounds. To analyze the morphofunctional structure of the fish assemblage from a tidal flat on the Brazilian coast, we conducted standardized sampling using nine different fishing gears. The geometric morphometric method was applied to describe the fish shapes and verify the morphological structure of the assemblage. Here, we present the influence/susceptibility of each gear type on the morphological diversity of the fish assemblage. The results indicated that beach seine, otter trawl, marginal encircling gillnet, and fish traps, together, were the most effective gears to represent the maximum morphological variability of fish inhabiting that tidal flat. Moreover, the assemblage showed high morphological redundancy considered as a resistance of the ecosystem for avoiding functional diversity loss, emphasizing the importance of complementary gear use when determining fish assemblages in a conservation context.

“…A canonical variate analysis (CVA) was computed on the reduced PCA matrix to summarise the variation between localities maximising their distances (Linde et al, 2004). Finally, the identification of the different otolith patterns was established from distance values using a cluster analysis with unweighted pair group method of arithmetic averages (UPGMA) algorithm based on the Euclidean distance (Tuset et al, 2014). Finally, significant differences between the means of groups formed was tested using a multiple variance analysis (MANOVA) and the sequential Bonferroni correction for multiple comparisons (Rice, 1989).…”

Plasticity in the shape and growth pattern of asteriscus otolith of black prochilodus Prochilodus nigricans (Teleostei: Characiformes: Prochilodontidae) freshwater Neotropical migratory fish

et al. 2018

Using morphometric measurements and wavelets functions, the asterisci otoliths of curimatã, Prochilodus nigricans were analysed to identify the variation in shape and growth increment of individuals from Solimões, Japurá and Negro rivers of the Amazon basin, Brazil. The morphometric and morphological analyses did not reveal evidences of population segregation among rivers, but variations were found in the estimation of otolith growth increment. Also, the otolith shape showed a high variability between individuals, identifying four morphotypes. Morphotype 1 shows a more oval shape with a posterior zone clearly rounded; Morphotype 2 shows the posterior zone rounded, but the anterior end is more elongated; Morphotype 3 shows a completely different shape, elliptic-pentagonal and Morphotype 4 shows the posterior zone rounded, but the anterior end is more elongated and it is the pattern with antirostrum and rostrum more pointed and a deep notch. Therefore, the otolith shape exhibited a phenotypic plasticity that it was not associated with the metabolism of otolith growth. Whereas the otolith shape indicated a homogeneity in the sound perception through Amazon basin, the growth rates revealed an adaptive mechanism to environmental conditions or migratory process of this species.
