Abstract

ABSTRACT Locomotion has been a well-studied avenue for questions regarding the costs of autotomy. However, previous studies have focused on traditional means of locomotion such as walking, running, or swimming; an unexplored aspect of locomotion as it relates to the costs of autotomy is the dorso-ventral righting reflex, or DVRR. Using a comprehensive set of treatment groups, we explored how autotomy affects the DVRR in the crab Hemigrapsus nudus. Our results suggested that missing walking legs had no impact on an animal’s ability to complete the DVRR. However, the enlarged claws of males were shown to impede the speed at which males can right themselves out of the compromising, supine position. This is a novel example of how a sexually selected trait can negatively affect animal locomotion.

紫滨蟹的背-腹侧翻正反射受性选择蟹爪的影响，而不受自断腿的影响

运动已经被充分研究了关于自体切开术成本的问题。然而，之前的研究主要集中在传统的运动方式上，如步行、跑步或游泳;一个未被探索的运动方面，因为它涉及到自切开术的成本是背-腹侧翻正反射，或DVRR。通过一组综合治疗组，我们探讨了自体切开术如何影响裸半月蟹的DVRR。我们的研究结果表明，失去行走腿对动物完成DVRR的能力没有影响。然而，研究表明，雄性的大爪子阻碍了雄性从妥协的仰卧姿势中恢复过来的速度。这是一个关于性选择特征如何对动物运动产生负面影响的新例子。

期刊介绍： Marine and Freshwater Behaviour and Physiology is devoted to the publication of papers covering field and laboratory research into all aspects of the behaviour and physiology of all marine and freshwater animals within the contexts of ecology, evolution and conservation. As the living resources of the world’s oceans, rivers and lakes are attracting increasing attention as food sources for humans and for their role in global ecology, the journal will also publish the results of research in the areas of fisheries biology and technology where the behaviour and physiology described have clear links to the contexts mentioned above. The journal will accept for publication Research Articles, Reviews, Rapid Communications and Technical Notes (see Instructions for authors for details). In addition, Editorials, Opinions and Book Reviews (invited and suggested) will also occasionally be published. Suggestions to the Editor-In-Chief for Special Issues are encouraged and will be considered on an ad hoc basis. With the goal of supporting early career researchers, the journal particularly invites submissions from graduate students and post-doctoral researchers. In addition to recognising the time constraints and logistical limitations their research often faces, and their particular need for a prompt review process, accepted articles by such researchers will be given prominence within the journal (see Instructions for authors for details).
