不同种类的水黾将腿的速度与它们的身体大小相匹配，以最大限度地提高它们的起跳速度而不破坏水面，这可能有助于进化出优化的腿结构，以利用水面张力。目前尚不清楚水黾是如何实现这种匹配的。个人可以根据他们的体重和运动经验来调整他们的腿部运动吗？在这里，我们测试了水黾Gerris latiabdominis是否会根据他们的个人经验调整跳跃行为，以及实验中增加的体重如何影响这一过程。雌性，而不是雄性，以体重依赖的方式改变它们的跳跃行为，但只有在频繁跳跃时才会改变。他们这样做是在水表面张力物理所设定的环境约束下进行的。雌性调节跳跃的能力可能代表了它们对交配时体重的频繁增加或减少的适应，在交配过程中，雄性分别骑在雌性身上，开始或结束。这表明，优化生物力学的自然选择与交配适应的性选择相结合，形成了这种最佳利用水面张力的能力，这可能有助于Gerromorpha的适应性辐射进入半水生生态位的多样性。
Different species of water striders match leg speeds to their body sizes to maximize their jump take off velocity without breaking the water surface, which might have aided evolution of leg structures optimized for exploitation of the water surface tension. It is not understood how water striders achieve this match. Can individuals modify their leg movements based on their body mass and locomotor experience? Here we tested if water striders, Gerris latiabdominis, adjust jumping behaviour based on their personal experience and how an experimentally added body weight affects this process. Females, but not males, modified their jumping behaviour in weight-dependent manner, but only when they experienced frequent jumping. They did so within the environmental constraint set by the physics of water surface tension. Females’ ability to adjust jumping may represent their adaptation to frequent increases or decreases of the weight that they support as mating bouts, during which males ride on top of females, start or end, respectively. This suggests that natural selection for optimized biomechanics combined with sexual selection for mating adaptations shapes this ability to optimally exploit water surface tension, which might have aided adaptive radiation of Gerromorpha into a diversity of semiaquatic niches.
