Understanding sexual dimorphism is very important in studies of insect evolution. Though has been the subject numerous entomological there have no examined Dorcadion anatolicum Pic, 1900 which endemic to Turkey. In this study, using geometric morphometrics, we analyzed size and shape pronotum specimens collected from Konya Province. Results morphometrics revealed that can be effectively used mo...

Knowledge about biological shape has important implications in biology and biomedicine, but the underlying genetic mechanisms for shape variation have not been well studied. Statistical models play a pivotal role in mapping specific quantitative trait loci (QTLs) that contribute to biological shape and its developmental trajectories. We describe and assess a statistical framework for shape gene...

Understanding the morphology of the scapula of Gorilla and Pan is crucial to scientists who find fossil ape scapulae and need to assign them to taxa and interpret the functional significance of their morphology. While differences between the shapes of Gorilla and Pan scapulae are known, a morphological link between locomotor patterns and scapular shape has yet to be determined. Using geometric ...

We present a quantitative analysis of sexual dimorphism and geographic variation in the skull of Myotis nigricans (Schinz, 1821) assessed by geometric morphometrics. Differences in size and shape of skulls were investigated using 30 landmarks plotted on two-dimensional images of lateral and ventral views. Results of geometric morphometrics revealed sexual dimorphism in the centroid size of the ...

the geometric morphometrics method was applied to study the morphological differences in 95 specimens of kura barbel (barbus lacerta, heckel 1834) collected from three riverine ecosystems of the sefidrud basin, viz. taleghan, totkabon and kloraz rivers.  for this purpose, the left sides of the specimens were photographed. then, 14 landmark-points were defined and digitized on 2d pictures using ...

Previous studies have suggested that female facial attractiveness is associated with exaggerated sex-specific facial traits and averageness. Here we applied geometric morphometrics, a method for multivariate statistical analysis of shape, to measure geometric averageness and geometric sexual dimorphism of natural female face profiles. Geometric averageness and geometric sexual dimorphism correl...

Abstract Today’s typical application of geometric morphometrics to a quantitative comparison organismal anatomies begins by standardizing samples homologously labelled point configurations for location, orientation, and scale, then renders the ensuing comparisons graphically thin-plate spline as applied group averages, principal components, regression predictions, or canonical variates. The sca...
