许多动物的性格特征都有基于运动的隐性定义，可以直接或间接地影响生态和进化过程。因此，有人提出，动物运动研究可以受益于承认和研究一致的个体间差异（个性），相反，动物个性研究可以采用更定量的运动模式表示。使用高分辨率的三棘鱼（Gasterosteus aculeatus）的跟踪数据，我们检查了离散时间序列运动数据分析中常用的四个运动参数的可重复性（时间静止，步长，转向角度，爆发频率）和动物个性研究中常用的四个行为参数（旅行距离，空间使用，自由水中的时间和物体附近的时间）。鱼表现出可重复的个体间差异，在运动和行为参数时，观察到在一个简单的环境中，有两个，三个或五个庇护所。此外，花更少的时间静止，采取更直接的路径，和不太常见的突发旅行（运动参数）的个人，被发现旅行更远，探索更多的坦克，花更多的时间在开放的水域（行为参数）。我们的案例研究表明，这两种方法-量化运动和行为参数-是大致相同的，我们建议运动参数可以被视为“微观人格”特征，引起广泛一致的个体间行为差异。这一发现对人格和运动生态学研究领域都有启示。例如，对运动参数的研究可以提供一种稳健的方式来分析难以或不可能使用标准化行为测定来研究的物种中的个体个性。我们使用高分辨率的三棘鱼（Gasterosteus aculeatus）的跟踪数据来检查离散时间序列运动数据分析中常用的运动参数和动物个性研究中常用的行为参数的可重复性。我们发现，运动和行为参数是大致相同的，捕捉类似的个体间的变化。我们认为，运动参数可以被视为“微观人格”特征，导致广泛一致的个体间行为差异。
Many animal personality traits have implicit movement‐based definitions and can directly or indirectly influence ecological and evolutionary processes. It has therefore been proposed that animal movement studies could benefit from acknowledging and studying consistent interindividual differences (personality), and, conversely, animal personality studies could adopt a more quantitative representation of movement patterns. Using high‐resolution tracking data of three‐spined stickleback fish (Gasterosteus aculeatus), we examined the repeatability of four movement parameters commonly used in the analysis of discrete time series movement data (time stationary, step length, turning angle, burst frequency) and four behavioral parameters commonly used in animal personality studies (distance travelled, space use, time in free water, and time near objects). Fish showed repeatable interindividual differences in both movement and behavioral parameters when observed in a simple environment with two, three, or five shelters present. Moreover, individuals that spent less time stationary, took more direct paths, and less commonly burst travelled (movement parameters), were found to travel farther, explored more of the tank, and spent more time in open water (behavioral parameters). Our case study indicates that the two approaches—quantifying movement and behavioral parameters—are broadly equivalent, and we suggest that movement parameters can be viewed as “micropersonality” traits that give rise to broad‐scale consistent interindividual differences in behavior. This finding has implications for both personality and movement ecology research areas. For example, the study of movement parameters may provide a robust way to analyze individual personalities in species that are difficult or impossible to study using standardized behavioral assays. We use high‐resolution tracking data of three‐spined stickleback fish (Gasterosteus aculeatus) to examine the repeatability of movement parameters commonly used in the analysis of discrete time series movement data and behavioral parameters commonly used in animal personality studies. We show that movement and behavioral parameters are broadly equivalent, capturing similar interindividual variation. We suggest that movement parameters can be viewed as “micropersonality” traits that give rise to broad‐scale consistent interindividual differences in behavior.
