The adaptive significance of dwarf males is addressed in deep-sea barnacles. First, microsatellite markers were developed in Scalpellum stearnsii, and the reproductive success of their dwarf males was studied. Small males attained higher reproductive success than larger ones. Second, life history traits were studied and some pieces of information were obtained in this species and in a related species, S. scalpellum, in situ and/or in the aquarium. Third, using mathematical models and theoretical synthesis by reviewing relevant studies, it was suggested that dwarf males evolved under low-density conditions.

深海藤壶解决了矮化雄性的适应性意义。首先，在 Scalpellum stearnsii 中开发了微卫星标记，并研究了其矮化雄性的繁殖成功率。体型较小的雄性比体型较大的雄性获得了更高的繁殖成功率。其次，在原位和/或在水族馆中研究了该物种和相关物种 S. spinellum 的生活史特征并获得了一些信息。第三，通过回顾相关研究，利用数学模型和理论综合，提出侏儒雄性是在低密度条件下进化的。
