- 摘要：
- A recent geometric morphometric study on certain landbird lineages revealed that a major part of the variation in beak shape is accounted

- of its distribution. A great morphological diversity in leaf shapes, including strong deviations from the typical lanceolate and acute leaf shape was revealed
Data from: Convergent evolution of floral shape tied to pollinator shifts in Iochrominae (Solanaceae)
- 负责人：
- DOI：
- doi:10.5061/dryad.5jn7b
- 摘要：
- Flower form is one of many floral features thought to be shaped by pollinator-mediated selection. Although the drivers of variation in flower shape
Data from: Does diet drive the evolution of head shape and bite force in chameleons of the genus Bradypodion?

- 摘要：
- etimes conflicting demands. Consequently, head shape varies greatly depending on the environment and dietary ecology of an organism. Moreover, given its role
Data from: Leaf shape tracks transitions across forest-grassland boundaries in the grass family (Poaceae)
