Behavioural consistency (i.e. personality) is an important aspect of behavioural ecology that has yet to be thoroughly examined in amphibians. Currently published studies often address only one or two aspects of personality, using many different methods for evaluating behavioural consistency. This is the first study focusing on all relevant behavioural traits and their relationships in urodele amphibians. Based on three trials within the experiment, we examined the consistency of activity (time spent moving), the boldness (latency of the first movement and time spent escaping) and the exploration (number of visited segments of the test arena) of 42 smooth newts (Lissotriton vulgaris). Individual consistency, calculated through the intraclass correlation coefficient (ICC), was low in newt activity (ICC = 0.192) and was moderate in boldness (0.476) and in exploration (0.403). Activity was moderately consistent for each trial (0.425), indicating possible habituation, supported by a decrease in mean activity throughout the trials. Newt activity, shyness and exploration were correlated throughout the experiment, suggesting the possible existence of a common selective pressure. With a summary of existing studies and their effect sizes, we aim to highlight the inconsistencies in the methods and in the results of these studies, to emphasize the need for a complex approach to the study of amphibian personality and the need for a standardized methodology, which would solve the current difficulties in comparing published results.

个体在探索和害羞中的一致性，但在平滑new中却没有活动：寻常的Lissotriton：习惯的影响？

行为一致性（即人格）是行为生态学的重要方面，尚待两栖动物的研究。当前发表的研究通常使用许多不同的方法来评估行为一致性，仅涉及人格的一两个方面。这是第一项研究，主要关注尾部两栖动物的所有相关行为特征及其关系。根据实验中的三项试验，我们检查了42个平滑new的活动性（移动时间），大胆性（第一移动的潜伏时间和逃逸时间）和探索性（测试区域访问段的数量）的一致性。（寻常的Lissotriton）。通过类内相关系数（ICC）计算得出的个体一致性在t活动中较低（ICC = 0.192），在勇气（0.476）和探索（0.403）中中等。每个试验的活动均中等程度一致（0.425），表明可能的习惯，并伴随着整个试验平均活动的减少。在整个实验过程中，的活动，羞怯和探索都相互关联，表明可能存在共同的选择压力。在总结现有研究及其效果大小的基础上，我们旨在突出这些研究方法和结果的不一致之处，以强调需要一种复杂的方法来研究两栖动物性格，以及需要一种标准化的方法，这将解决目前比较已发布结果的困难。
