- 摘要:
- in the field. To disentangle the influence of the two main determinants, inter-tree competition and directionality of above-canopy solar radiati
Data from: Persistent directional selection on body size and a resolution to the paradox of stasis
- 负责人:
- DOI:
- doi:10.5061/dryad.v4t80
- 摘要:
- Directional selection on size is common but often fails to result in micro-evolution in the wild. Similarly, macro-evolutionary rates in size are low

Data from: Directional selection effects on patterns of phenotypic (co)variation in wild populations

- 摘要:
- theoretical expectations, namely an increase of both phenotypic integration and (co)variance in the direction of selection and a re-alignment of the major axis
