摘要:
The trade-off between offspring size and number is a central component of life-history theory, postulating that larger investment into offspring size

摘要:
Life history theory predicts a trade-off between offspring size and number. However, the role of intra-litter phenotypic variation in shaping

摘要:
ing life history strategies among environments. The offspring size-number trade-off connects three traits whereby a constant reproductive allocation (R) constrains how the number

摘要:
1. Size-number trade-offs in reproduction are commonly observed in nature. Bumble bee (Bombus spp.) colonies produce workers that vary considera

摘要:
at the onset of breeding was there evidence for a trade-off between offspring size and number. Our results demonstrate that individual variation
