Data from: Social selection acts on behavior and body mass but does not contribute to the total selection differential in Eastern chipmunks
- 负责人：
- DOI：
- doi:10.5061/dryad.ghx3ffbjc
- 摘要：
- mated social selection and its contribution to total selection in the wild. We estimated natural and social selection gradients on exploration, docility, and body mass
Data from: Phenotypic selection in natural populations: what limits directional selection?
- 负责人：
- DOI：
- doi:10.5061/dryad.7996
- 摘要：
- fitness components reduced total directional selection in most study systems. Comparisons of selection gradients and selection differentials suggest that correlated

- 摘要：
- Avian plumage colours are some of the most conspicuous sexual ornaments, and yet standardized selection gradients for plumage colour have ra
Data from: A test of the hypothesis that correlational selection generates genetic correlations

- 摘要：
- on. We test this hypothesis with a meta-analysis utilizing empirical estimates of correlational selection gradients and measures of the correlation bet
Data from: The strength of phenotypic selection in natural populations
- 负责人：
- DOI：
- doi:10.5061/dryad.166
- 摘要：
- mated the strength of linear and quadratic selection in terms of standardized selection gradients or differentials on natural variation in quantitative tra

- 负责人：
- DOI：
- doi:10.5061/dryad.9sn3k
- 摘要：
- ranunculoides flowers and its pollinators along an altitudinal gradient on the eastern Qinghai-Tibet Plateau, and measured phenotypic selection by pollinators
Data from: Subtle but ubiquitous selection on body size in a natural population of collared flycatchers over 33 years
- 负责人：
- DOI：
- doi:10.5061/dryad.24tm0
- 摘要：
- . Multivariate selection gradient vectors were longer than corresponding vector of univariate gradients and had more constrained direction. Correlational selection had littl
Data from: Niche construction affects the variability and strength of natural selection

- DOI：
- doi:10.5061/dryad.g66n3h5
- 摘要：
- -constructed sources of selection that buffer environmental variation will result in reduced variation in selection gradients, including reduced variation bet

- Bateman gradient Natural selection path analysis phenotypic selection pollinator-mediated selection structural equation model experimental manipulation
- DOI：
- doi:10.5061/dryad.s1q0h
- 摘要：
- ween pollen receipt and seed production. Indeed, the Bateman gradient was strongest when pollination was limited, suggesting potential for sexual selection
Data from: Persistent directional selection on body size and a resolution to the paradox of stasis

- DOI：
- doi:10.5061/dryad.v4t80
- 摘要：
- r size is embodied in the opposing signs of the two selection gradients.
