Impact of environmental and genetic factors on the scale shape of zebrafish,Danio rerio(Hamilton 1822): A geometric morphometric study

Do the Fish Scales Shape of Mugil curema Reflect the Genetic Structure Using Microsatellites Markers and the Mexican Marine Ecoregions Classification?

“…The genetic groups of M. curema previously differentiated through microsatellite markers (Pacheco-Almanzar et al, 2017;Pacheco-Almanzar, 2019) were successfully distinguished regarding the shape of their scales, indicating that both genetic and environmental factors can significantly influence the formation of the scale shape. Staszny et al (2013) and Albertson et al (2018) reported results similar to those of this study for other fish species. Finally, the integration of genetic data through phenotypic traits (the shape of the scale in this case) has the potential to provide a broad view of the roles of adaptation and evolution of phenotypes.…”

“…As far as we know, only two studies have analyzed the influence of genetics on the shape of fish scales, those of Staszny et al (2013) and Albertson et al (2018). The two articles agree that both genetic and environmental factors can significantly influence the formation of scales, and thus the shape of a scale may be used as a tool to explain and detect the potential variability of the environmental influences that affect groups of genetically homogeneous fish.…”

Scale morphometry allows discrimination of European sardine Sardina pilchardus and round sardinella Sardinella aurita and among their local populations

“…Seven landmarks were recorded on each scale (Fig. ) using psUtil v. 1.60 (Rohlf, ) and tpsDig2 v. 2.17 (Rohlf, ) utility programmes to identify the key features as suggested by Staszny et al (). Shape data of the scales were processed with the software programme MorphoJ v. 1.06d (Klingenberg, , ).…”

“…percentage of the total variation in scale shape accounts for the allometric effect which is 0⋅87% (P < 0⋅05). This value is considered to be relatively low compared with other scale shape analyses (Staszny et al, 2013). Therefore, the use of regression residuals was justified.…”

Unravelling the stock structure of the Persian brown trout by otolith and scale shape

“…Because the environmental and genetic factors can affect otolith and scale shape (Bayley, ; Lombarte & Lleonart, ; Staszny et al ., ; Vignon & Morat, ), both structures have been used to study different biological aspects of several fish species. Specifically, otolith shape has been previously used to delimit species and stocks of salmonids, including Atlantic salmon and brown trout (L'Abée‐Lund, ).…”
