Animal personality has received increasing interest and acknowledgment within ecological research over the past two decades. However, some areas are still poorly studied and need to be developed. For instance, field studies focused on invertebrates are currently highly underrepresented in the literature. More studies including a wider variety of traits measured and species tested are needed to improve our understanding of trait-correlation patterns and generalities. We studied nine behavioral traits, in the damselfly , from an array of three experiments: (i) courtship, (ii) aggressiveness, and (iii) boldness, and calculated their repeatability. The behaviors were measured twice in two different contexts: (i) undisturbed territory and (ii) partially deteriorated territory. Traits related to courtship and boldness were all repeatable across the two contexts. Among aggressive behaviors, only one trait (number of hits) was repeatable. This work demonstrates, for the first time, the presence of within-population personality differences in an adult damselfly in the wild. We further propose as a promising model species for testing personality in the wild under highly controlled environmental conditions.
在过去二十年中,动物个性在生态研究中受到了越来越多的关注和认可。然而,一些领域仍研究不足,需要进一步拓展。例如,目前针对无脊椎动物的野外研究在文献中所占比例极低。需要开展更多研究,涵盖更广泛的测量性状和受试物种,以增进我们对性状关联模式和普遍性的理解。我们通过一系列三个实验,研究了豆娘的九种行为性状:(i)求偶行为、(ii)攻击性和(iii)大胆程度,并计算了它们的重复性。这些行为在两种不同情境下进行了两次测量:(i)未受干扰的领地和(ii)部分恶化的领地。与求偶和大胆程度相关的性状在两种情境下均具有重复性。在攻击性行为中,只有一个性状(攻击次数)具有重复性。这项研究首次证明了野生成年豆娘种群内部存在个性差异。我们进一步提出,在高度可控的环境条件下,豆娘是一种很有前景的用于野外个性测试的模式物种。
