Variation in mandible shape and size due to osteoporosis: Geometric morphometrics study
International Journal of Interdisciplinary Dentistry, 2023 Objective: Assessing whether it is possible screening women with osteoporosis through geometric morphometrics based on panoramic x-ray. Materials and Methods: Leukoderma women, after menopause, 40 years old (or older), with confirmed medical diagnosis ...

Leaf shape and size variability of Dryas octopetala in the Central Great Caucasus (the Kazbegi region, Georgia) based on traditional and geometric morphometrics [PDF]
Botanica SerbicaWhile soil pH is known to be a key driver of plant species composition, we still have a poor understanding of the quantification of the responses of leaf traits to different soil types, especially in highly sensitive alpine environments susceptible to

PLoS ONE, 2015 In vitro rearing is an important and useful tool for honey bee (Apis mellifera L.) studies. However, it often results in intercastes between queens and workers, which are normally are not seen in hive-reared bees, except when larvae older than three days

Geometric morphometric footprint analysis of young women [PDF]
Journal of Foot and Ankle Research, 2013 AbstractBackgroundMost published attempts to quantify footprint shape are based on a small number of measurements. We applied geometric morphometric methods to study shape variation of the complete footprint outline in a sample of 83 adult women.MethodsThe outline of the footprint, including the toes, was represented by a comprehensive set of 85 ...

Comprehensive Methods for Leaf Geometric Morphometric Analyses [PDF]
BIO-PROTOCOL, 2017 Leaf morphometrics are used frequently by several disciplines, including taxonomists, systematists, developmental biologists, morphologists, agronomists, and plant breeders to name just a few. Leaf shape is highly variable and can be used for identifying species or genotypes, developmental patterning within and among individuals, assessing plant health,

Pathologies of Between-Groups Principal Components Analysis in Geometric Morphometrics
Evolutionary biology, 2019 Good empirical applications of geometric morphometrics (GMM) typically involve several times more variables than specimens, a situation the statistician refers to as “high p/n,” where p is the count of variables and n the count of specimens.
