父母照顾的持续时间和未来的生育成功之间可能存在权衡。传统上，关于父母照料成本的研究包括父母离家出走。然而，在第一个离合器失败后制造第二个离合器是一种补偿行为，发生在幼崽失败的情况下。在这项研究中，试图通过延长育儿期或增加孵化规模来检测早熟线虫的母体护理成本，以防止通过孵化成功进行补偿。结果表明，尽管我之前的研究表明，在该物种移除离合器后，这些间隔缩短了，但操纵并没有改变离窝之间的间隔。在本研究中，减少离合器大小的操作增加了后续离合器的大小。
There may be a trade-off between the duration of parental care and future reproductive success. Traditionally, studies about the cost of parental care have included the removal of the parent. However, producing a secondary clutch after the failure of the first one is a compensatory behaviour that occurs in cases of brood failure. In this study, attempts were made to detect the cost of maternal care in the earwig,Anisolabis maritima(Dermaptera: Anisolabididae) by either extending the period of care or increasing the brood size to prevent compensation through the brood’s success. The results indicated that manipulation did not change the inter-clutch interval, although my previous study revealed shortening of these intervals after the removal of the clutch in this species. In this study, decreased clutch size manipulation increased the size of the following clutch.
