在双亲照顾的物种中，父母经常调整他们的照顾能力。合作伙伴可以直接（直接响应配偶先前的努力，依次修改他们的努力）或间接（父母通过后代的乞讨率修改他们的努力）相互监控。本研究探讨是否合作伙伴谈判或乞讨幼虫最好的解释男性供应inNicrophorus quadripunctatus。男性接近幼虫喂养的频率没有增加，无论是女性删除或女性障碍。然而，幼虫乞讨男性增加女性去除，但不与女性障碍。这表明，幼虫是不受影响的变化，女性投资的照顾，但幼虫的反应，没有一个女性的父母。虽然幼虫乞求更多的男性时，女性被删除，我的研究结果表明，男性没有增加他们的照顾，这表明男性是不敏感的变化，他们的合作伙伴的状态或后代的行为inN。四斑的。
In species showing biparental care, parents often adjust their level of care facultatively. Partners can potentially monitor each other directly (modify their effort sequentially in direct response to the prior effort of their mate) or indirectly (parents modify their effort through the begging rates of their offspring). This study examined whether partner negotiation or begging by larvae best explains male provisioning inNicrophorus quadripunctatus. The frequency of males approaching larvae to feed did not increase with either female removal or female handicapping. However, larval begging toward males increased with female removal, but not with female handicapping. This suggests that larvae are not affected by the change of female investment in care but larvae reacted to the absence of a female parent. Although larvae begged more towards the male when the female was removed, my findings show that males did not respond by increasing their care, which suggests that males are insensitive to variation in their partner’s state or offspring behaviour inN. quadripunctatus.
