Data from: The consequences of genetic variation in male sex peptide gene-expression levels for SP retention and egg laying in female Drosophila

- DOI:
- doi:10.5061/dryad.77hn0
- 摘要:
- fitness. One Acp, the sex peptide (SP), is largely responsible for a dramatic increase in female egg laying and decrease in female receptivity after copula

Data from: Variation in laying date in relation to spring temperature in three species of tits (Paridae) and pied flycatchers Ficedula

- DOI:
- doi:10.5061/dryad.sq651
- 摘要:
- Parus major, blue tits Cyanistes caeruleus and marsh tits Poecile palustris, which generally start egg laying between the last week of April and the first week

Data from: Covariance of paternity and sex with laying order explains male bias in extra-pair offspring in a wild bird population

- 摘要:
- the laying order of eggs in the clutch. However, previous studies suggest that, unlike the decline in EPO with laying order, the relationship bet

Data from: Laying sequence interacts with incubation temperature to influence rate of embryonic development and hatching synchrony in a precocial

- DOI:
- doi:10.5061/dryad.mg5mk
- 摘要:
- Incubation starts during egg laying for many bird species and causes developmental asynchrony within clutches. Faster development of late-laid eggs

- 摘要:
- sticity in these adaptations are seldom studied. In birds, temperature could affect egg characteristics. Higher temperatures during egg-laying may reduce

Data from: Food-deprivation affects egg laying and maternal care but not offspring performance in a beetle
- 负责人:
- DOI:
- doi:10.5061/dryad.8189524
- 摘要:
- t food-deprived females took longer to start egg laying than control females, which may allow them more time to feed from the carcass. Ther

Data from: Mid-winter temperatures, not spring temperatures, predict breeding phenology in the European starling Sturnus vulgaris
- 负责人:
- DOI:
- doi:10.5061/dryad.1jt86
- 摘要:
- In many species, empirical data suggest that temperatures less than 1 month before breeding strongly influence laying date, consistent
