Morphometric and Genetic Description of Trophic Adaptations in Cichlid Fishes
Biology, 2022 Since Darwin, biologists have sought to understand the evolution and origins of phenotypic adaptations. The skull is particularly diverse due to intense natural selection on feeding biomechanics.

Morphometric description of strength and degradation in porous media [PDF]
International Journal of Solids and Structures, 2022 The influence of the microstructural geometry on the behavior of porous media is widely recognized, particularly in geomaterials, but also in biomaterials and engineered materials. Recent advances in imaging techniques, such as X-ray microcomputed tomography, and in modeling make it possible to capture the exact morphometry of the microstructure with ...

Sexual dimorphism in the walrus mandible: comparative description and geometric morphometrics
PeerJ, 2022 The modern walrus Odobenus rosmarus is characterized by marked sexual dimorphism, related to its polygynous behavior and the aggressive competition between males during the breeding season. Previous studies treated skeletal sexual dimorphism in walruses either qualitatively or with basic quantitative measurements.

Description and Analysis of Spatial Patterns in Geometric Morphometric Data [PDF]
Evolutionary Biology, 2019 The development of techniques for the acquisition of high-resolution 3D images, such as computed tomography and magnetic resonance imaging, has opened new avenues to the study of complex morphologies. Detailed descriptions of internal and external traits can be now obtained, allowing the intensive sampling of surface points. In this paper, we introduce

Assessing the reproducibility of discriminant function analyses. [PDF]
, 2015 Data are the foundation of empirical research, yet all too often the datasets underlying published papers are unavailable, incorrect, or poorly curated. This is a serious issue, because future researchers are then unable to validate published results or ...
