Data from: Genetic hitchhiking and the dynamic buildup of genomic divergence during speciation with gene flow
- 负责人:
- DOI:
- doi:10.5061/dryad.t894r
- 摘要:
- h direct selection on a locus and genetic hitchhiking. “Divergence hitchhiking” (DH) theory postulates that divergent selection on a locus reduces
Data from: Are pollinators the agents of selection on flower colour and size in irises?
- 负责人:
- DOI:
- doi:10.5061/dryad.44mt9
- 摘要:
- selective pressures independent of pollinators. We quantified phenotypic pollinator-mediated selection on flower colour and size in two colour polymorphic Iris spec
Data from: A test of the hypothesis that correlational selection generates genetic correlations
- 负责人:
- DOI:
- doi:10.5061/dryad.rc071b2v
- 摘要:
- Theory predicts that correlational selection on two traits will cause the major axis of the bivariate G matrix to orient itself in the same directi
Data from: Selection past impacts the strength of an aquatic trophic cascade
- 负责人:
- DOI:
- doi:10.5061/dryad.7mc7r30
- 摘要:
- on of natural selection can affect the strength of a trophic cascade. Natural selection can therefore act as a mechanism coupling ecological dynamics across trophic levels
Data from: Reversal of response to artificial selection on body size in a wild passerine
- 负责人:
- DOI:
- doi:10.5061/dryad.v50r8
- 摘要:
- in the imposed directions. However, artificial selection was counteracted by reduced production of recruits in offspring of artificially selected parents. This res
Data from: Multilevel selection with kin and non-kin groups, experimental results with Japanese quail (Coturnix japonica)
- 负责人:
- Muir, William M.
- DOI:
- doi:10.5061/dryad.1012q
- 摘要:
- of breeding programs, multilevel selection is easy to implement and is expected to give near optimal responses with reduced rates of inbreeding as compared
Data from: Experimental evidence for the role of sexual selection in the evolution of cuticular hydrocarbons in the dung beetle, Onthophagus taurus
- 负责人:
- DOI:
- doi:10.5061/dryad.1kt2n9v
- 摘要:
- during female mate choice. However, evidence that CHCs evolve in response to sexual selection is generally lacking, and there is a need to extend
Data from: Spatially and temporally varying selection on intrapopulation quantitative trait loci for a life history trade-off in Mimulus guttatus
- 负责人:
- DOI:
- doi:10.5061/dryad.s0n20
- 摘要:
- and genetic drift, but theoretical and experimental studies each suggest that mutation-selection balance insufficient to explain extant genetic variation in mos
Data from: Sex ratio and density affect sexual selection in a sex-role reversed fish
- 负责人:
- DOI:
- doi:10.5061/dryad.4365v
- 摘要:
- Understanding how demographic processes influence mating systems is important to decode ecological influences on sexual selection in nature
Data from: Estimating phenotypic selection in age-structured populations by removing transient fluctuations

- DOI:
- doi:10.5061/dryad.37mc0
- 摘要:
- components in a house sparrow population illustrates the applicability of the theory to analyze selection on the mean phenotype in fluctuating age
