父母在决定后代的表型方面发挥着关键作用。然而，相对较少的研究调查父母是否能够以持续的方式改变后代的行为并持续到成年。通过对埋葬甲虫 Nicrophorus vespilloides 的实验，我们研究了父母创造的发育环境如何影响其后代成年后的翅膀形态，以及对成年飞行行为的相关影响。埋葬甲虫表现出复杂的双亲照顾，但后代可以在没有父母供给的情况下生存。通过在孵化前去除父母，同时保持营养环境恒定，我们研究了对后代形态和行为的下游影响。在父母不在的情况下发育的幼虫比在父母存在的情况下发育的幼虫具有相对更长、更细长的翅膀。飞行磨机测试表明，飞行性能取决于发育过程中父母的存在，而不是翅膀形状。我们的研究结果表明，父母对后代的行为有着长期的影响，即使在他们成年后，他们也会影响后代的形态和飞行行为。我们研究了父母对后代形态和飞行行为的影响。父母的照顾质量会影响翅膀形状的异速性和飞行性能。机翼形状和机身尺寸不会影响飞行磨机的飞行性能。父母的照顾质量影响后代成年后的形态和行为。
Parents play a key role in determining the phenotype of their offspring. However, relatively few studies have investigated whether parents can change their offspring's behaviour in a sustained way that persists into adulthood. With experiments on the burying beetle, Nicrophorus vespilloides, we investigated how the developmental environment created by parents affects their offspring's wing morphology in adulthood, and the correlated effects on adult flight behaviour. Burying beetles exhibit complex biparental care, but offspring can survive without parental provisioning. By removing parents just prior to hatching, while holding the nutritional environment constant, we investigated the downstream consequences for offspring morphology and behaviour. Larvae that developed in the absence of their parents had relatively long and more slender wings than those that developed in their parents' presence. Flight mill tests revealed that flight performance was dependent on the presence of parents during development but not on wing shape. Our results demonstrate that parents have long-lasting effects on the behaviour of their offspring, by influencing the morphology and flight behaviour of their young even after they have matured into adults. We investigated parental influence on offspring's morphology and flight behaviour. Parental care quality affects wing shape allometries and flight performance. Wing shape and body size do not affect flight performances in a flight mill. Parental care quality affects offspring's morphology and behaviour into adulthood.
