Data from: Do wolf spiders' egg-sacs emit tactochemical signals perceived by mothers?

- DOI:

- 摘要:
- discriminate between egg-sacs differencing in mass (empty or not) as they do not hang an empty egg-sac but do not discriminate between egg-sacs with viable

Data from: Egg investment in response to the helper presence in cooperatively breeding Tibetan ground tits
- 负责人:
- DOI:
- doi:10.5061/dryad.7d028rp
- 摘要:
- studies found that helpers improve total nestling provisioning rates and fledgling recruitment, but have no apparent effects on the number and body mass

Data from: Disentangling genetic and prenatal sources of familial resemblance across ontogeny in a wild passerine.

- 摘要:
- e able to partition variation in body mass across ontogeny into the effects of genes and the effects of between- clutch variation in egg characteristics. We show tha

Data from: Egg size and offspring performance in the collared flycatcher (Ficedula albicollis): a within-clutch approach
- 负责人:
- DOI:
- doi:10.5061/dryad.1758
- 摘要:
- t on nestling mass disappeared as nestlings approached fledging. Thus, there seems to be limited potential for a laying female to exploit within-clutch egg

- DOI:
- doi:10.5061/dryad.v540q
- 摘要:
- ween clutch size, direct, and indirect care. Both egg size and direct care were positively correlated with dispersal mass, whereas clutch size was negatively

- 摘要:
- ), egg mass (h2= 0.82 ± 0.30) and hatchling mass (h2= 1.01 ± 0.31) (population = fixed effect), we found very low additive genetic variation. Large non-additive

- 摘要:
- r, but not too early (15 days before mean hatch). Increased egg volume and duckling mass reduced the probability of ducking mortality (?egg volume = ?0.155, 85% CI

- 摘要:
- ant inbreeding depression was found in pupal mass, pupal time, thorax mass, abdomen fat content, egg hatching success, and fecundity. However, stress resistance traits
