Advances in Geometric Morphometrics [PDF]

open access: yesEvolutionary Biology, 2009
Geometric morphometrics is the statistical analysis of form based on Cartesian landmark coordinates. After separating shape from overall size, position, and orientation of the landmark configurations, the resulting Procrustes shape coordinates can be used for statistical analysis.

Potential Niche Modeling Distribution and Wing Geometric Morphometrics of Apis mellifera In The Brazilian Pantanal

open access: yesSociobiology, 2021
The ecological niche models can be important for biogeographic patterns and processes and geometric morphometrics involves identifying changes that have occurred and comparing them to other specimens from different places and/or environmental conditions,

Shape mapping: genetic mapping meets geometric morphometrics [PDF]

open access: bronzeBriefings in Bioinformatics, 2013
Knowledge about biological shape has important implications in biology and biomedicine, but the underlying genetic mechanisms for shape variation have not been well studied. Statistical models play a pivotal role in mapping specific quantitative trait loci (QTLs) that contribute to biological shape and its developmental trajectories.

Archaeophenomics of ancient domestic plants and animals using geometric morphometrics : a review

open access: yesPeer Community Journal, 2022
Geometric morphometrics revolutionized domestication studies through the precise quantification of the phenotype of ancient plant and animal remains. Geometric morphometrics allow for an increasingly detailed understanding of the past agrobiodiversity ...

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

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.

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.

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.
