- 摘要：
- shape, however, remains unknown. Using scanning electron microscopy, we quantified inter- and intra-specific variation in sperm head morphology across 36
Data from: Do constructional constraints influence cyprinid (Cyprinidae: Leuciscinae) craniofacial coevolution?

- 摘要：
- jacent structures could represent an evolutionary compromise. For example, evolutionary trade-offs resulting from limited space in the head could have influenced
Data from: Association between integration structure and functional evolution in the opercular four-bar apparatus of the threespine stickleback
