Geometric morphometrics of rodent sperm head shape. [PDF]
PLoS ONE, 2013 Mammalian spermatozoa, particularly those of rodent species, are extremely complex cells and differ greatly in form and dimensions. Thus, characterization of sperm size and, particularly, sperm shape represents a major challenge. No consensus exists on a

Geometric morphometrics in the cloud
Infection, Genetics and Evolution, 2019 XYOM, for XY Online Morphometrics, is an online implementation of the geometric morphometric (GM) approach. It is a platform-independent product, and is presented here as an optional alternative software to client side morphometrics software. From the point of view of the user, the interesting features of a web application are: no download, no ...

Exploring desert-adapted beetles with 3D geometric morphometrics [PDF]
Scientific ReportsDarkling beetles (Tenebrionidae) are a diverse and ecologically significant group, particularly in arid environments, yet their taxonomy remains problematic due to scarcity of phylogenetic contributions and robust morphological investigations. This study

Geometric morphometrics of endophytic oviposition traces of Odonata (Eocene, Argentina) [PDF]
Royal Society Open Science, 2020 The insertion of the Odonata ovipositor in the plant tissue generates a scar that surrounds the eggs (trace). In insects, individual egg traces are known to vary in size, but their variation in individual shape is mostly unknown.

A Novel Approach to Study Cranial Shape in Children with Normal and Sagittal Synostosis: An Application of Geometric Morphometrics [PDF]
Neurologia Medico-ChirurgicaTo provide appropriate treatment, neurosurgeons and pediatricians must understand the chronological changes of the cranial morphology in normal children and the differences between normal and sagittal synostosis children. However, this issue has remained

Integrative species delimitation in the common ophiuroid Ophiothrix angulata (Echinodermata: Ophiuroidea): insights from COI, ITS2, arm coloration, and geometric morphometrics [PDF]
PeerJ, 2023 Ophiothrix angulata (Say, 1825) is one of the most common and well-known ophiuroids in the Western Atlantic, with a wide geographic and bathymetric range. The taxonomy of this species has been controversial for a century because of its high morphological
