Data from: Egg size investment in superb fairy-wrens: helper effects are modulated by climate
- 负责人:
- DOI:
- doi:10.5061/dryad.087b9
- 摘要:
- in the cooperatively breeding superb fairy-wren Malurus cyaneus. We focus on egg size because in this species egg size influences offspring size, and females reduce egg

- 摘要:
- n the lineage with an inconsistent and variable SSD (L. a. exigua). L. a. agilis shows lower offspring size (egg mass, hatchling mass) and higher clutch mass

- 摘要:
- . In addition, the effect of coloration on thermoregulation should change with egg size, as smaller eggs have higher surface-volume ratios and greater convective

- 摘要:
- -size variation when large offspring are superior competitors (i.e. competition is asymmetric), but small offspring are superior colonisers. Empirical tests ar
Data from: Temperature, size, reproductive allocation, and life-history evolution in a gregarious caterpillar

- Pimentel, Carla
- DOI:
- doi:10.5061/dryad.8gt6m3m4
- 摘要:
- of the length of the larval period and its relation with different climatic variables, final mass and adult size, egg size and number, colony size, and mortality
Data from: Effect of composition on shape of bird eggs
- 负责人:
- DOI:
- doi:10.5061/dryad.q8rp3
- 摘要:
- dered the underlying reasons for such interspecific egg shape variability. This study investigated how the size and composition, i.e. proportions of shell, yolk
Data from: Offspring fitness and the optimal propagule size in a fluctuating environment
- 负责人:

- 摘要:
- , Bathypolypodidae and Enteroctopodidae, and clade 2 including species of Octopodidae. Egg size, development mode and all environmental variables exhibited
Data from: The effect of egg size on hatch time and metabolic rate: theoretical and empirical insights on developing insect embryos
- 负责人:
- DOI:

- 摘要:
- on egg production, using an egg-substitution experiment in wild, free-ranging Lincoln’s sparrows (Melospiza lincolnii). I discovered that females adjusted the size
