- 摘要:
- allocation to sex under stress to allow low-fitness individuals to recombine their genotype, potentially increasing offspring fitness. However, effecti

- 摘要:
- Increased variance in the reproductive success of males relative to females favors mothers that optimally allocate sons and daughters to maximize
Data from: Local selection underlies the geographic distribution of sex-ratio drive in Drosophila neotestacea

- 摘要:
- c distance based on autosomal microsatellite loci. Instead, our results indicate that ecological selection on sex-ratio drive varies among populati
Data from: Covariance of paternity and sex with laying order explains male bias in extra-pair offspring in a wild bird population

- DOI:
- doi:10.5061/dryad.b6428
- 摘要:
- It has been hypothesized that parents increase their fitness by biasing the sex ratio of extra-pair offspring (EPO) towards males. Here, we report
Data from: The spatial ecology of sex ratios in a dioecious plant: relations between ramet and genet sex ratios

- 摘要:
- 1. In clonal dioecious plants, the frequency and spatial distribution of flowering ramets contains information on the underlying genet sex rati

- 摘要:
- predictions of evolutionary sex-allocation theories, independent of parental modulation of primary sex ratios. However, none of the handful of previous studies
