Integrating whole‐bone and regional analyses to understand human scapular growth
The Anatomical Record, EarlyView.Abstract This study investigates ontogenetic changes in human scapular morphology using three‐dimensional geometric morphometrics with whole‐bone and region‐specific analyses. The aim is to evaluate whether the scapula follows a regular developmental pattern and whether its functionally distinct components, the scapular spine (SS) and glenoid fossa ...

The Later Stone Age calvaria from Iwo Eleru, Nigeria: morphology and chronology. [PDF]
PLoS ONE, 2011 BACKGROUND: In recent years the Later Stone Age has been redated to a much deeper time depth than previously thought. At the same time, human remains from this time period are scarce in Africa, and even rarer in West Africa.

Quality and Sensory Evaluation for Goat Meat Using Generalized Procrustes Analysis [PDF]
Journal of Animal and Veterinary Advances, 2011 The aim of this study was to examine relationships among experts, sex, genotypes and sensory variables by Procrustes analysis. About 10 meat samples involved different genotypes and sex were evaluated by 12 expert assessors for four sensory characteristics (color, texture, taste-odor and acceptability).

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.

Generalized Procrustes Analysis: A Tool for Exploring Aggregates and Persons
Applied Multivariate Research, 2009 Gower (1975) introduced Generalized Procrustes Analysis (GPA) as a multivariate statistical technique for analyzing three-dimensional data matrices. The current paper presents a non-technical introduction to the logic underlying GPA and then presents a completely worked example using genuine data.

Generalized procrustes analysis (GPA) as a tool to discriminate among sheep breeds [PDF]
Archives Animal Breeding, 2014 Abstract. Forty male lambs of five Southern Spanish breeds were used to study the effects of the breed in their sensorial characteristics. The used breeds were: Segureña, Spanish Merino, Grazalema Merino, Churra Lebrijana and Montesina breeds. Milk lambs were slaughtered at 12 kg of live weight.

Tracing the evolutionary history of the morpho‐anatomy of baculum in primates
The Anatomical Record, EarlyView.Abstract Animal morphology reflects both evolutionary history and present‐day adaptation. Male mammal copulatory structures such as the baculum (penile bone) are ideal for studying these processes because of their complexity and high interspecific variability. In primates, however, research has focused mostly on baculum length.

Astragalus ecomorphology in Quaternary elephantids
Journal of Quaternary Science, EarlyView.ABSTRACT The astragalus plays a fundamental role in the graviportal locomotion of proboscideans, reflecting the biomechanical constraints imposed by large body masses. This study analyses the morphological variability of the astragalus in Quaternary elephantids using linear biometry and 3D geometric morphometrics, incorporating an unpublished ...
