Automatic ear detection and feature extraction using Geometric Morphometrics and convolutional neural networks

IET Biometrics, 2017
Accurate gathering of phenotypic information is a key aspect in several subject matters, including biometrics, biomedical analysis, forensics, and many other.

Cortical bone distribution in the human mandibular symphysis: Ontogenic and morphometric approaches in archeological context

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 ...

Assessing the application of landmark-free morphometrics to macroevolutionary analyses

BMC Ecology and Evolution
The study of phenotypic evolution has been transformed in recent decades by methods allowing precise quantification of anatomical shape, in particular 3D geometric morphometrics.

When Shape Defines: Geometric Morphometrics Applied to the Taxonomic Identification of Leaf-Footed Bugs of the Genus Acanthocephala (Hemiptera: Coreidae)

Diversity
The study of qualitative morphological variation is essential for taxonomists and professionals involved in the identification and diagnosis of species of agricultural importance. This becomes particularly critical when quarantine decisions depend on the

Inferring locomotor behaviours in Miocene New World monkeys using finite element analysis, geometric morphometrics and machine-learning classification techniques applied to talar morphology

Journal of the Royal Society Interface, 2018
The talus is one of the most commonly preserved post-cranial elements in the platyrrhine fossil record. Talar morphology can provide information about postural adaptations because it is the anatomical structure responsible for transmitting body mass ...

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 ...

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.

Inter‐ and intraspecific variation in theropod dinosaur dental microwear and its palaeoecological implications

The Anatomical Record, EarlyView.
Abstract Differences in skull and tooth morphology, stomach contents, and estimated bite force between medium‐to‐large sized (≥100 kg) predatory theropod dinosaurs have long been suspected to correlate with differences in their diets and dietary guilds (e.g., hypercarnivory, piscivory).

Much more than their fangs: Macroscopic anatomy of the brain of Bothrops moojeni Hoge 1966 (Squamata, Serpentes, Viperidae)

The Anatomical Record, EarlyView.
Abstract Neuroanatomical research has progressed considerably in several vertebrate lineages, yet studies of reptilian brain morphology remain markedly underdeveloped. Here we provide the first description of macroscopic brain anatomy and its ontogeny in the viperid Bothrops moojeni, based on a sample of seven individuals.
