Head and mandible shapes are highly integrated yet represent two distinct modules within and among worker subcastes of the ant genus Pheidole

open access: yesEcology and Evolution, 2021
Ants use their mandibles for a wide variety of tasks related to substrate manipulation, brood transport, food processing, and colony defense. Due to constraints involved in colony upkeep, ants evolved a remarkable diversity of mandibular forms, often ...

Standardisation in 3D Geometric Morphometrics: Ethics, Ownership, and Methods [PDF]

open access: yesArchaeologies, 2018
The collection and analysis of 3D digital data is a rapidly growing field in archaeology, anthropology, and forensics. Even though the 3D scanning of human remains in archaeology has been conducted for over 10 years, it is still frequently considered as a new field.

New Geometric Morphometric Insights in Digital Taphonomy: Analyses into the Sexual Dimorphism of Felids through Their Tooth Pits

open access: yesApplied Sciences, 2021
Recent studies using geometric morphometrics for taphonomy have yielded interesting results, opening new horizons of research in both archaeological and paleontological sites. Here we present the analysis of tooth pits left by male and female individuals

Measurement error using a SeeMaLab structured light 3D scanner against a Microscribe 3D digitizer [PDF]

open access: yesPeerJ, 2021
Background Geometric morphometrics is a powerful approach to capture and quantify morphological shape variation. Both 3D digitizer arms and structured light surface scanners are portable, easy to use, and relatively cheap, which makes these two capturing

Association between ribs shape and pulmonary function in patients with Osteogenesis Imperfecta

open access: yesJournal of Advanced Research, 2020
The aim of the present study was to test the hypothesis that ribs shape changes in patients with OI are more relevant for respiratory function than thoracic spine shape.

Analysis of gender differences on pyriform aperture of human skulls using geometric morphometric method

open access: yesFolia Morphologica, 2022
BACKGROUND: Piriform aperture is anterior opening of the nasal cavity formed by bones of the viscerocranium and knowledge about differences between genders is important for forensic scientists, anthropologists, orthopaedists, neurosurgeons and vascular ...

3D geometric morphometric analysis of the proximal epiphysis of the hominoid humerus

open access: yesJournal of Anatomy, 2012
AbstractIn this study we perform a three‐dimensional geometric morphometric (3D GM) analysis of the proximal epiphysis of the humerus in extant great apes, including humans, in order to accurately describe the functional anatomical differences between these taxa.
