Monogenean anchor morphometry: systematic value, phylogenetic signal, and evolution [PDF]

PeerJ, 2016
Background. Anchors are one of the important attachment appendages for monogenean parasites. Common descent and evolutionary processes have left their mark on anchor morphometry, in the form of patterns of shape and size variation useful for systematic ...

A Brief Overview of Stereology and Morphometry Method in Histology and Biology

Turkish Journal of Agriculture: Food Science and Technology
Quantitative analyses in biological science are especially important in terms of determining and comparing the geometric properties of biological structures. Stereology and morphometry are two important complementary methods frequently used in this field.

Sexual dimorphism in Kinosternon scorpioides (Linnaeus, 1766) from the Brazilian Amazon

Brazilian Journal of Biology, 2022
The sexual dimorphism of the Kinosternon scorpioides was evaluated using two different techniques (linear and geometric morphometry) from images and linear measurements of the carapace and plastron of adults (male and female).
