作者在之前的两篇论文(Jones,1973; Jones和Hall,1973)中表明,基于食物密度对幼虫阶段的生存至关重要的想法的幼虫模型可以解释黑线鳕和鳕鱼等物种的大部分早期生活史。本文总结了之前的结果。然后,我们使用的模型,从理论上考虑幼虫的生存可能会受到影响的大小范围内的食物生物消费。这为自然选择如何通过这个变量来决定这些物种的卵的大小,从而决定繁殖力提供了深入的了解。
The authors have been able to show, in two previous papers (Jones, 1973; Jones and Hall, 1973) that a larval model, based on the idea that food density is critical for survival during the larval stage, can explain much of the early life history of species such as haddock and cod.In this paper the previous results are summarized. We then used the model to consider theoretically how larval survival might be influenced by the size range of food organisms consumed. This has provided insight into how natural selection, by operating on this variable, might have determined egg size, and hence fecundity, in these species.
