Data from: Sperm competition generates evolution of increased paternal investment in a sex role-reversed seed beetle
- 负责人：
- DOI：
- doi:10.5061/dryad.550g3
- 摘要：
- t underpins sex role reversal in this system is the result of male-male reproductive competition rather than of direct selection for males to enhance
Data from: Persistence of an extreme male-biased adult sex ratio in a natural population of polyandrous bird

- DOI：
- doi:10.5061/dryad.1m8r2
- 摘要：
- that parental sex role reversal may occur in populations that exhibit extreme male-biased ASR.
Data from: Sex-chromosome recombination in common frogs brings water to the fountain-of-youth
- 负责人：
- DOI：
- doi:10.5061/dryad.57kg0
- 摘要：
- results from occasional events of sex reversal. If recombination arrest in males is controlled by maleness per se (and not by genotype
Data from: Differential introgression of a female competitive trait in a hybrid zone between sex-role reversed species

- DOI：
- doi:10.5061/dryad.t2m0hg0
- 摘要：
- and genetic introgression between species. We examine a hybrid zone between sex-role reversed, Neotropical shorebird species, the northern jacana (Jacana spinosa) and wattled
Data from: Genetic evidence for polygynandry in the black-striped pipefish Syngnathus abaster: a microsatellite-based parentage analysis
- 负责人：
- DOI：
- doi:10.5061/dryad.n3q59
- 摘要：
- Sexual selection theory predicts that, in organisms with reversed sex roles, more polyandrous species exhibit higher levels of sexual
Data from: Sex-specific arrival times on the breeding grounds: hybridizing migratory skuas provide empirical support for the role of sex ratios
- 负责人：
- DOI：
- doi:10.5061/dryad.6v5g3
- 摘要：
- , sex differences in timing of arrival should be driven by the operational sex ratio, shifting toward protogyny in female-biased populations. However, empirical
Data from: Sex roles, parental care and offspring growth in two contrasting coucal species
- 负责人：
- Goymann, Wolfgang
- DOI：
- doi:10.5061/dryad.23gt0
- 摘要：
- k loop between sexual selection, body size, and adult sex-ratio may then stabilize reversed sex-roles in competition and parental care.
Data from: Male pregnancy and bi-parental immune priming
- 负责人：
- DOI：
- doi:10.5061/dryad.r6624
- 摘要：
- d. Our study shows that sex-role reversal in connection with male pregnancy opens the door for bi-parental influences on offspring immunity, and may represe
Data from: Social monogamy versus polyandry: ecological factors associated with sex-roles in two closely related birds within the same habitat
- 负责人：
- DOI：
- doi:10.5061/dryad.4nt54
- 摘要：
- food abundance, high population density, high degree of nest loss, and male bias in the adult sex ratio are ecological conditions that facilitate role reversal

- 摘要：
- ge partners. Yet, females provide protein-richer eggs when the same individual mates with a smaller than a larger male. In the present study, we allowed ea
