Data were collected to determine whether there are intrinsic, short-term cycles of aggression during the reproductive stage in the male three-spined stickleback. The subjects were studied in the lab, where model female-female were presented for 10 + min. The frequency of court-ship behavior, biting, and a variety of nest activities were measured, as a function of time. It was found that biting does undergo regular and striking internal fluctuations, and that this is correlated with the cycling of a number of other behaviors.
收集数据以确定雄性三刺鱼在繁殖阶段是否存在内在的短期攻击周期。在实验室对这些研究对象进行研究，向它们展示模拟雌鱼10多分钟。测量求偶行为、撕咬以及各种筑巢活动的频率随时间的变化情况。研究发现，撕咬行为确实会经历规律且显著的内在波动，并且这与许多其他行为的周期性变化相关。
