The Anatomical Record, EarlyView.Abstract The vertebrate skull is composed of bones derived from neural crest cells and mesoderm. The evolutionary capacity of the skull has been linked, in part, to the emergence of neural crest cells; however, this increased capacity for evolutionary change requires that variation within neural crest‐ and mesoderm‐derived bones remains partly ...

Does 3D Phenotyping Yield Substantial Insights in the Genetics of the Mouse Mandible Shape?
G3: Genes, Genomes, Genetics, 2016 We describe the application of high-resolution 3D microcomputed tomography, together with 3D landmarks and geometric morphometrics, to validate and further improve previous quantitative genetic studies that reported QTL responsible for variation in the ...

Size, shape, and form: concepts of allometry in geometric morphometrics
Development, Genes and Evolution, 2016 Allometry refers to the size-related changes of morphological traits and remains an essential concept for the study of evolution and development.

The Anatomical Record, EarlyView.Abstract The human mandibular symphysis concentrates multiaxial loads during function and remodels throughout growth, but the precise mechanisms underlying cortical bone shape during growth remain relatively unexplored. Approaches based solely on thickness or external cortical contours provide only partial insights and do not capture the functional ...

Morphological variation under domestication: how variable are chickens? [PDF]
Royal Society Open Science, 2018 The process of domestication has long fascinated evolutionary biologists, yielding insights into the rapidity with which selection can alter behaviour and morphology.

Three‐dimensional geometric morphometric analysis of diaphragmatic dome motion in COPD patients
The Anatomical Record, EarlyView.Abstract Diaphragmatic dysfunction is a hallmark of chronic obstructive pulmonary disease (COPD), especially in emphysema, where hyperinflation alters diaphragm geometry and impairs inspiratory mechanics. However, quantitative three‐dimensional (3D) assessments of diaphragmatic dome shape and motion across COPD phenotypes are limited.

Leaf geometric morphometrics among populations of Dalbergia ecastaphyllum (L.) Taub.
Bioscience Journal, 2019 Leaves are plant structures that express important traits of the environment where they live. Leaf description has allowed identification of plant species as well as investigation of abiotic factors effects on their development, such as gases, light ...

Functional morphology and integration of corvid skulls - a 3D geometric morphometric approach [PDF]
, 2009 BACKGROUND: Sympatric corvid species have evolved differences in nesting, habitat choice, diet and foraging. Differences in the frequency with which corvid species use their repertoire of feeding techniques is expected to covary with bill-shape and with ...
