The relative contributions of environmental, maternal and additive genetic factors to the Lifetime reproductive success (LRS) determine whether species can adapt to rapid environmental change. Yet to date, studies quantifying LRS across multiple generations in marine species in the wild are non-existent. Here we used 10-year pedigrees resolved for a wild orange clownfish population from Kimbe Island (PNG) and a quantitative genetic linear mixed model approach to quantify the additive genetic, maternal and environmental contributions to variation in LRS for the self-recruiting portion of the population. We found that the habitat of the breeder, including the anemone species and geographic location, made the greatest contribution to LRS. There were low to negligible contributions of genetic and maternal factors equating with low heritability and evolvability. Our findings imply that our population will be susceptible to short-term, small-scale changes in habitat structure and may have limited capacity to adapt to these changes.

强大的栖息地和较弱的遗传效应决定了野生小丑鱼种群终生繁殖的成功。

环境，母体和加性遗传因素对终生生殖成功（LRS）的相对贡献决定了物种是否能够适应快速的环境变化。迄今为止，还没有关于野生海洋物种中多代LRS量化的研究。在这里，我们使用了10年谱系，对来自金贝岛（PNG）的野生橙色小丑鱼种群进行了解析，并使用了定量遗传线性混合模型方法来量化该种群自招募部分对LRS变异的累加遗传，母体和环境贡献。人口。我们发现繁殖者的栖息地，包括海葵的种类和地理位置，对LRS的贡献最大。遗传和母体因素的贡献低至可忽略不计，相当于低的遗传性和可进化性。我们的发现表明，我们的人口将容易受到栖息地结构的短期，小规模变化的影响，并且适应这些变化的能力可能有限。
