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).

Acta Tropica, 2022 The study of geometric morphometry has an impact on Triatominae studies. Currently, several taxonomic and systematic studies use this approach. The Triatominae subfamily comprises three fossil species and 154 extant species potentially capable of transmitting Trypanosoma cruzi, the causative agent of Chagas disease.

Assessing the severity of diatom deformities using geometric morphometry [PDF]
Botany Letters, 2018 Deformities in diatoms are increasingly used as an indicator of toxic stress in freshwaters. However, the percentage of deformities alone often fails at highlighting the magnitude of toxic exposure. An approach combining the assessment of deformities coupled with information on their severity could improve the sensitivity of this biomarker.

Rat airway morphometry measured from in situ MRI-based geometric models [PDF]
Journal of Applied Physiology, 2012 Rodents have been widely used to study the environmental or therapeutic impact of inhaled particles. Knowledge of airway morphometry is essential in assessing geometric influence on aerosol deposition and in developing accurate lung models of aerosol transport.
