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.

ZooMS confirms geometric morphometrics species identification of ancient sheep and goat [PDF]

Royal Society Open Science, 2023
Geometric morphometrics can effectively distinguish isolated third lower molars of present-day sheep and goat, but its applicability to archaeological specimens has yet to be established.

DeepWings©: Automatic Wing Geometric Morphometrics Classification of Honey Bee (Apis mellifera) Subspecies Using Deep Learning for Detecting Landmarks

Big Data and Cognitive Computing, 2022
Honey bee classification by wing geometric morphometrics entails the first step of manual annotation of 19 landmarks in the forewing vein junctions. This is a time-consuming and error-prone endeavor, with implications for classification accuracy. Herein,

Geometric morphometrics versus DNA barcoding for the identification of malaria vectors Anopheles dirus and An. baimaii in the Thai-Cambodia border

Scientific Reports, 2022
Anopheles (Cellia) dirus Peyton & Harrison and Anopheles baimaii Sallum & Peyton are sibling species within the Dirus complex belonging to the Leucosphyrus group, and have been incriminated as primary vectors of malaria in Thailand. In the present study,

Breaking Symmetry: Fluctuating Asymmetry and Geometric Morphometrics as Tools for Evaluating Developmental Instability under Diverse Agroecosystems

Symmetry, 2020
Fluctuating asymmetry (FA), in contrast with other asymmetries, is the bilateral asymmetry that represents small, random developmental differences between right and left sides.

Shape variation and sex differences of the adult human mandible evaluated by geometric morphometrics. [PDF]

Sci Rep
In cases of osseous defects, knowledge of the anatomy, and its age and sex-related variations, is essential for reconstruction of normal morphology. Here, we aimed at creating a 3D atlas of the human mandible in an adult sample using dense landmarking ...

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
