- 摘要:
- m two prior generation hatchery parents had <20% of the reproductive success of natural origin spawners. In contrast, hatchery females originating from a cro

- 摘要:
- The trade-off between reproductive investment in early versus late life is central to life-history theory. Despite abundant empirical evidence
Data from: Energetic investment associated with vitellogenesis induces an oxidative cost of reproduction

- 摘要:
- 1.Oxidative stress is a potential cost of reproduction, but conclusive evidence for this relationship is lacking. The goal of this study

- DOI:
- doi:10.5061/dryad.1b8m917
- 摘要:
- when southern elephant seals are predicted to optimally skip reproduction in order to maximize lifetime reproductive output as a function of current body mass, maternal age
