Data from: The differential contributions of herkogamy and dichogamy as mechanisms of avoiding self-interference in four self-incompatible Epimedium
- 负责人:
- DOI:
- doi:10.5061/dryad.46kb4
- 摘要:
- Self-interference is one of the most important selective forces in shaping floral evolution. Herkogamy and dichogamy both can achieve reductions
Data from: Selection on floral design in Polemonium brandegeei (Polemoniaceae): female and male fitness under hawkmoth pollination

- 摘要:
- . The spatial separation of sex-organs, herkogamy, is believed to limit sexual interference in hermaphrodite flowers. Reverse herkogamy (stigma recessed below anther
Data from: Does urbanization promote floral diversification? Implications from changes in herkogamy with pollinator availability in an urban

- doi:10.5061/dryad.pd775
- 摘要:
- populations may suggest the presence of high reproductive assurance by selfing. The stigma height and degree of herkogamy significantly decreased with increased
Data from: Experimental insights on the function of ancillary pollen and stigma polymorphisms in plants with heteromorphic incompatibility

- DOI:
- doi:10.5061/dryad.r48vj
- 摘要:
- Most heterostylous plants possess a reciprocal arrangement of stigmas and anthers (reciprocal herkogamy), heteromorphic self-incompatibility
Data from: Heterostyly promotes disassortative pollination and reduces sexual interference in Darwin’s primroses: evidence from experimental studies

- 摘要:
- h pollen types. Reciprocal herkogamy promotes differential placement of pollen onto different parts of the pollinator's body, thus effecting transfer of mor
Data from: Populations with greater flexibility in floral traits modify mating system in response to the pollinator environment

- 摘要:
- habitats to create high- and low-pollination environments. Floral visitors were observed and pollen limitation, dichogamy, herkogamy, and pollen per
Data from: Selection on Polemonium brandegeei (Polemoniaceae) flowers under hummingbird pollination: in opposition, parallel, or independent of

- 摘要:
- . We documented contrasting selection on sex organ positioning through female function, with hummingbirds selecting for stigmas exserted beyond the anther
Data from: Evolution of the selfing syndrome: anther orientation and herkogamy together determine reproductive assurance in a self-compatible plant
- 负责人:
- DOI:
- doi:10.5061/dryad.0s63q
- 摘要:
- in a common-garden experiment. To examine whether anther-stigma distance and anther orientation are subject to directional and/or correlational selection, and whether this is bec
Data from: Multiple aspects of the selfing syndrome of the morning glory Ipomoea lacunosa evolved in response to selection: a Qst-Fst comparison

- 摘要:
- traits. We also find evidence of selection for reduced herkogamy in I. lacunosa, consistent with selection driving both the transition in mating system
Data from: Small and ugly? Phylogenetic analyses of the “selfing syndrome” reveal complex evolutionary fates of monomorphic primrose flowers

- 摘要:
- for evolution of selfing. We find similar overall variability of homostylous and heterostylous species, except for diminished herkogamy in homostyles. Bayesian
