Data from: The evolution of trade-offs under directional and correlational selection
- 负责人：
- 摘要：
- Using quantitative genetic theory we develop predictions for the evolution of trade-offs in response to directional and correlational selection
Data from: Survival of the fattest? Indices of body condition do not predict viability in the brown anole (Anolis sagrei)

- correlational selection directional selection quadratic selection residual index scaled mass index selection gradient viability selection mark-recapture demography
- 摘要：
- c, and correlational selection gradients obtained using Ri and Mi were highly correlated with one another. Relative to variance in selection among replicates and to error
Data from: Complex patterns of multivariate selection on the ejaculate of a broadcast spawning marine invertebrate
- 负责人：
- 摘要：
- tes can be subject to natural and/or sexual selection, which can impose both linear (directional) and nonlinear (stabilizing, disruptive and correlational) selection
Data from: The search for Pleiades in trait constellations: functional integration and phenotypic selection in the complex flowers
- 负责人：
- 摘要：
- ted with the empirical matrix, and the CDA revealed three putative modules. Analyses of phenotypic selection showed significant linear and correlational gradients, lending
Data from: Frequency-dependent and correlational selection pressures have conflicting consequences for assortative mating in a color-polymorphic
- 负责人：
- 摘要：
- ng selection pressures. Balancing selection among morphs preserves equilibrium frequencies, while correlational selection maintains favorable trait combinations within ea

- 摘要：
- , quadratic, and correlational selection gradients were estimated from the single-stimulus data. Significant directional selection is acting on call durati
Data from: An experimental test of density-dependent selection on temperament traits of activity, boldness and sociability
- 负责人：
- 摘要：
- favoured less active individuals. A significant negative correlational selection on activity and boldness existed for body growth rate irrespecti
Data from: Costs of resistance and correlational selection in the multiple-herbivore community of Solanum carolinense

- 摘要：
- for florivores, and lowest for folivores. In addition, significant correlational selection gradients were found for ten pairs of resistance measures, which
Data from: Sexual selection as a promoter of population divergence in male phenotypic characters? A study on mainland and islet lizard populations
- 负责人：
- 摘要：
- kely to mate with orange-throated males with small body sizes, and male body size and coloration were therefore subject to correlational sexual selection
Data from: Phenotypic selection on floral traits in an urban landscape
- 负责人：
- Irwin, Rebecca
- 摘要：
- c nor correlational selection significantly differed between urban and non-urban sites. Pollination was associated with selection for larger floral display size in urban compared
