Web8 - 12 May 2024, Barcelona, Spain. The field of geometric morphometrics (GM) is concerned with the quantification and analysis of patterns of shape variation, and its covariation with other variables. The goal of this workshop is to provide participants with both working knowledge of the theory of geometric morphometrics, as well as practical ... WebFeb 3, 2024 · Here, we employ three-dimensional (3D) geometric morphometric (GM) techniques, enabling a more comprehensive analysis of shape . This approach allows us to analyse a possible signal trait in enough detail to allow a number of predictions regarding the potential signal of socio-sexual selection to be tested. These are as follows.

WebUsing geometric morphometrics, we determined the shape variation and disparity in the premaxillary bone, and the patterns of allometric trajectories between morphs in each system. We found a higher differentiation and disparity in the premaxilla shape between morphs from San Juan River basin than between the Lake Catemaco ones. We found …
