对环境变化的表型调整对于应对通常由出生分散造成的可能的环境不匹配特别相关。我们使用跨代跨移植田间实验来评估亲代和定居后水流环境对橙鳍海葵个体发育的形态和生理影响(在定居前和定居后)。与低水流亲本相比，高水流条件下出生的后代在定居前阶段的尾鳍长宽比(形状的复合衡量标准)高18%，定居后生长缓慢10%，定居后存活率降低55%。在安置期，尾鳍长度由亲本尾鳍长度决定。在定居后阶段，鱼类以相似的表型在高发育和低发育的流动环境中存活得同样好。然而，结果表明，尾鳍长度具有潜在的发育表型可塑性，在发育过程中，低流量时，尾鳍长度增加得更多。定居后，生长是唯一与亲本水流有关的形态或生理性状，在高水流条件下，生长和存活率低于亲本。这些结果为研究亲本在决定早期后代表型和随后的生长和存活方面的遗传和非遗传贡献提供了重要的见解。我们的结果还表明，后代可能具有应对广泛的当地环境的灵活性，包括那些与父母不同的环境。总体而言，这项研究的结果显示了生活在不同环境中的健康后果，以及在野生种群中父母和后代健康之间的可能权衡。阅读《华尔街日报》博客上这篇文章的免费简单语言摘要。
Phenotypic adjustments to environmental variation are particularly relevant to cope with putative environmental mismatches often imposed by natal dispersal.We used an intergenerational cross‐transplant field‐based experiment to evaluate the morphological and physiological effects of parental and postsettlement water flow environments on the orange‐fin anemonefishAmphiprion chrysopterusthrough ontogeny (at pre‐ and postsettlement stages).Offspring born from parents under high water flow had an 18% higher caudal fin aspect ratio (a compound measure of shape) at the presettlement stage, 10% slower growth after settlement, and 55% lower survival after settlement compared to offspring from low water flow parents. At the presettlement stage, caudal fin length was determined by parental caudal fin length. At the postsettlement stage, fish survived equally well with similar phenotypes in both high and low developmental flow environments. However, results suggest potential developmental phenotypic plasticity in caudal fin length, which increases more under low water flow during development. After settlement, growth was the only morphological or physiological trait that was associated with parental water flow, which was lower from parents under high flow, as was survival.These results give important insights into the parental contribution, both genetic and nongenetic, in determining early offspring phenotype and subsequent growth and survival. Our results also suggest that offspring may possess flexibility to cope with a wide range of local environments including those different from their parents. Overall, the findings of this study show the fitness consequences of living in different environments and the likely trade‐offs between parental and offspring fitness in a wild population.Read the free Plain Language Summary for this article on the Journal blog.
