Geometric morphometric analysis of mandibular ramus flexure
American Journal of Physical Anthropology, 2005AbstractMany characteristics of the human skeleton can only be assessed morphologically, which may be problematic due to factors such as interobserver error and difficulties with standardization. Flexure of the mandibular ramus is one of these traits, and various researchers found widely differing results using this morphological feature.

Geometric morphometric contribution to septal deviation analysis
Surgical and Radiologic Anatomy, 2019The nasal septum presents inter-individual conformational variations. The objectives of this study were to establish a validated protocol for nasal septum analysis using geometric morphometrics (GM) to establish a classification of septal deviations (SD).This was a retrospective study including two groups of patients: patients operated on by ...

Geometric morphometrics of clypeasteroids
2014The complex skeleton of echinoids shows a close relationship between structure and function that makes this clade a textbook example for the analysis of functional morphology. Clypeasteroids (“sand dollars”) are a group of irregular echinoids with flat body shape, which live as detritus feeders on marine softground.

Exploring Eucladoceros Ecomorphology Using Geometric Morphometrics
The Anatomical Record, 2014ABSTRACTAn increasingly common method for reconstructing paleoenvironmental parameters of hominin sites is ecological functional morphology (ecomorphology). This study provides a geometric morphometric study of cervid rearlimb morphology as it relates to phylogeny, size, and ecomorphology. These methods are then applied to an extinct Pleistocene cervid,

Protocol of Geometric Morphometrics for Teratogenicity Testing
Geometric morphometrics (GM) enables a quantitative study of shapes and forms allowing the identification and characterization of teratogenic malformations. The GM methodology offers several advantages in comparison to traditional biometric methods, such as higher detail and precision analysis. In this chapter, we describe the recent application of theMariana Caipira, Lei +2 more

[Principles and methods of geometric morphometrics].
Zhurnal obshchei biologii, 2003The basic concepts, notions and methods of geometric morphometrics (GM) are considered. This approach implies multivariate analysis of landmark coordinates located following certain rules on the surface of a morphological object. The aim of GM is to reveal differences between morphological objects by their shapes as such, the "size factor" being ...

Three-Dimensional Geometric Morphometrics in Paleoecology
2018Quantification and analysis of shape is an important component of many paleoecological studies. Geometric morphometrics is a powerful shape analysis tool that allows its user to compare entire regions of morphology, visualize shape differences between groups, and create visualizations based on real data. This method is rapidly becoming the standard for
