Data from: Infectious adaptation: potential host range of a defensive endosymbiont in Drosophila
- 负责人：
- DOI：
- doi:10.5061/dryad.m329j
- 摘要：
- a new species, a symbiont must survive and reproduce in the new host, undergo maternal transmission, and confer a selective benefit sufficient to overcome losse
Data from: A split sex ratio in solitary and social nests of a facultatively social bee
- 负责人：
- DOI：
- doi:10.5061/dryad.62dt334
- 摘要：
- A classic prediction of kin selection theory is that a mixed population of social and solitary nests of haplodiploid insects should exhibit a split
Data from: Indirect genetic effects underlie oxygen-limited thermal tolerance within a coastal population of chinook salmon
- 负责人：
- DOI：
- doi:10.5061/dryad.682ns
- 摘要：
- though these direct genetic effects explained 53% of the variation in resting heart rate (fH). Conversely, maternal effects had a significant influence

- DOI：
- doi:10.5061/dryad.rp131
- 摘要：
- Many studies of offspring size focus on differences in maternal investment that arise from ecological factors such as predation or competiti

- 负责人：
- DOI：
- doi:10.5061/dryad.d06j2
- 摘要：
- hybrid sunflower (Helianthus annuus) cross types to test how a cross type's maternal parent and nuclear genetic composition might affect its fate under

- 摘要：
- scus. To do so, we collected open-pollinated progeny from selected maternal plants, calculated mating system parameters using microsatellite genotyping and conducted sowing

- DOI：
- doi:10.5061/dryad.4fv71
- 摘要：
- Despite ample evidence for the presence of maternal effects (MEs) in a variety of traits and strong theoretical indications for thei

- 负责人：
- DOI：
- doi:10.5061/dryad.v2b8t
- 摘要：
- in its absence. We failed to detect evidence of additive genetic variation underlying tolerance, but did uncover the presence of a significant maternal line effect
Data from: Offspring fitness varies with parental extra-pair status in song sparrows, Melospiza melodia
- 负责人：
- DOI：
- doi:10.5061/dryad.6jk30
- 摘要：
- Numerous studies have tested for indirect selection on female extra-pair reproduction (EPR) by quantifying whether extra-pair young (EPY) are fitter
