Wing Morphometrics of Aedes Mosquitoes from North-Eastern France

open access: yesInsects, 2021
Background: In the context of the increasing circulation of arboviruses, a simple, fast and reliable identification method for mosquitoes is needed. Geometric morphometrics have proven useful for mosquito classification and have been used around the ...

Bat Species Comparisons Based on External Morphology: A Test of Traditional versus Geometric Morphometric Approaches. [PDF]

open access: yesPLoS ONE, 2015
External morphology is commonly used to identify bats as well as to investigate flight and foraging behavior, typically relying on simple length and area measures or ratios. However, geometric morphometrics is increasingly used in the biological sciences

Machine learning and geometric morphometrics to predict obstructive sleep apnea from 3D craniofacial scans.

open access: yesSleep Medicine, 2022
BACKGROUND Obstructive sleep apnea (OSA) remains massively underdiagnosed, due to limited access to polysomnography (PSG), the highly complex gold standard for diagnosis.

Immature instars of three species of Rhodnius Stål, 1859 (Hemiptera, Reduviidae, Triatominae): morphology, morphometry, and taxonomic implications

open access: yesParasites & Vectors, 2022
Background Among the 18 genera of the Triatominae subfamily, three stand out for their diversity and epidemiological importance: Triatoma, Panstrongylus, and Rhodnius.

Technical note: A technique to mount Sarcophagidae and Calliphoridae (Diptera) larvae for forensic identification using geometric morphometrics

open access: yesForensic Science International: Synergy, 2021
Geometric morphometric analyses use landmark coordinates from images of specific areas on specimens. Therefore, to minimize differences arising from human preparation, preparation of the specimen is crucial. The application of geometric morphometrics has

Using genomics, morphometrics, and environmental niche modeling to test the validity of a narrow-range endemic snail, Patera nantahala (Gastropoda, Polygyridae) [PDF]

open access: yesZooKeys, 2023
Terrestrial gastropods are among the most imperiled groups of organisms on Earth. Many species have a complex taxonomic history, often including poorly defined subspecies, most of which have not been the focus of modern systematics research.

The promise of geometric morphometrics [PDF]

open access: yesAmerican Journal of Physical Anthropology, 2002
Nontraditional or geometric morphometric methods have found wide application in the biological sciences, especially in anthropology, a field with a strong history of measurement of biological form. Controversy has arisen over which method is the "best" for quantifying the morphological difference between forms and for making proper statistical ...

An assessment of new character in hoverfly species delimitation using linear and geometric morphometrics – genus Merodon Meigen, 1803 (Diptera: Syrphidae) as a case study

open access: yesEuropean Journal of Taxonomy, 2023
Detection of morphologically indistinguishable cryptic species implies using an integrative taxonomic approach with a combination of molecular, contemporary morphological, ecological and other relevant analyses.

A Comparison of Traditional and Geometric Morphometric Techniques for the Study of Basicranial Morphology in Horses: A Case Study of the Araucanian Horse from Colombia

open access: yesAnimals, 2020
Skull size and shape have been widely used to study domestic animal populations and breeds. Although several techniques have been proposed to quantify cranial form, few attempts have been made to compare the results obtained by different techniques ...
