Uniquely positioned at the intersection of sexual selection, nutritional ecology and life-history theory, nuptial gifts are widespread and diverse. Despite extensive empirical study, we still have only a rudimentary understanding of gift evolution because we lack a unified conceptual framework for considering these traits. In this opinion piece, we tackle several issues that we believe have substantively hindered progress in this area. Here, we: (i) present a comprehensive definition and classification scheme for nuptial gifts (including those transferred by simultaneous hermaphrodites), (ii) outline evolutionary predictions for different gift types, and (iii) highlight some research directions to help facilitate progress in this field.
婚飞礼物独特地处于性选择、营养生态学和生活史理论的交叉点上,分布广泛且形式多样。尽管有大量实证研究,但我们对礼物进化仍只有初步的了解,因为我们缺乏一个统一的概念框架来考量这些特征。在这篇观点文章中,我们探讨了几个我们认为严重阻碍该领域进展的问题。在此,我们:(i)给出婚飞礼物(包括由同时雌雄同体转移的礼物)的全面定义和分类方案,(ii)概述不同礼物类型的进化预测,以及(iii)强调一些有助于推动该领域进展的研究方向。
