- 摘要:
- , and (3) the ability of viviparous females to decrease the mass of uterine embryos by reducing extra-embryonic water stores.
- Our analysis shows that squamate
Data from: Patterns of genetic variation in desiccation tolerance in embryos of the terrestrial-breeding frog, Pseudophryne guentheri

- 摘要:
- to such environmental perturbations. Here, we assess the level of heritable variation in the ability of embryos to tolerate desi
Data from: Maternal size and body condition predict the amount of post-fertilization maternal provisioning in matrotrophic fish

- 摘要:
- to fertilization) and post-fertilization (i.e. allocation to the embryo during pregnancy) maternal provisioning and how this ultimately affects offspring size
Data from: Long-term effect of yolk carotenoid levels on testis size in a precocial bird
- 负责人:
- DOI:
- doi:10.5061/dryad.523t4
- 摘要:
- a lower sperm production, we propose that carotenoid exposure during embryo development might influence a trade-off between ejaculate size and sperm quality.
Data from: Costs and benefits of polyandry in a placental poeciliid fish Heterandria formosa are in accordance with the parent-offspring conflict theory of placentation
- 负责人:
- DOI:
- doi:10.5061/dryad.6jp04633
- 摘要:
- In viviparous species, a conflict over maternal resource allocation may arise between mothers and embryos, between siblings, and between maternal
Data from: High food abundance permits the evolution of placentotrophy: evidence from a placental lizard, Pseudemoia entrecasteauxii
- 负责人:
- DOI:
- doi:10.5061/dryad.52n61
- 摘要:
- embryogenesis. If scarcity of food prevents successful embryogenesis, females should recoup nutrients allocated to embryos via abortion, reabsorption
Data from: Transgenerational effects in an ecological context: conditioning of adult sea urchins to upwelling conditions alters maternal provisi
- 负责人:
- DOI:
- doi:10.5061/dryad.4nv0nb8
- 摘要:
- lipid content. Developing embryos whose mothers were conditioned to simulated upwelling conditions (~1300 ?atm pCO?2, ~13°C) were greater in body size, although
Data from: Links between parental life histories of wild salmon and the telomere lengths of their offspring

- 摘要:
- , in particular egg size, were most strongly related to offspring telomere length at the embryonic stage, but then became weaker through development

- , or live young, and it influences ecological interactions, organism fitness, maternal investment, and embryonic development. Although multiple
Data from: Does the cost of development scale allometrically with offspring size?
- 负责人:
- DOI:

- 摘要:
- 1.Within many species, larger offspring have higher fitness. While the presence of an offspring size-fitness relationship is canonical
