Topological and variational modularity: A case study using the pectoral girdle across the Chrosomus eos‐neogaeus hybridization complex

open access: yesThe Anatomical Record, Volume 309, Issue 1, Page 130-165, January 2026.
Abstract Modularity and integration are key developmental properties and have remained central in evo‐devo research because of how they relate to evolvability. While modularity and integration have commonly been assessed with landmark‐based geometric morphometrics (GMM), other methods such as anatomical network analysis (AnNA) are increasingly being ...

The Geographical Differences in the Morphology of Diptychus maculatus: Environmental Driving Factors and Adaptive Evolution

open access: yesEcology and Evolution, Volume 16, Issue 1, January 2026.
This study morphologically analyzed 385 Diptychus maculatus from 5 Tarim River Basin populations. Using traditional and geometric morphometrics, it revealed environmental (high‐altitude cold, rapids, reservoir flows) and human‐driven morphological differentiation.
