在这一领域，竞争成功的表型决定因素并不总是绝对的。例如，比赛经验可能会改变未来的竞争表现。由于未来的比赛并不完全取决于表型属性，先前的经验也可能潜在地改变表型-适合性的联系。在这项研究中，我们考察了单一和多次经历对跳蛛Phidippus Clarus比赛结果的影响。我们还检查了随着个人获得更多的经验，表型-健康关联是否会发生变化。使用大小匹配的比赛和锦标赛设计，我们发现，获胜和失败的经验都会影响未来的比赛成功；具有先前获胜经验的男性更有可能赢得随后的比赛。尽管经验是未来比赛成功的重要决定因素，但在预测比赛结果时，男性体重的重要性大约是经验的1.3倍。尽管经验在决定比赛结果方面很重要，但选拔模式在不同回合之间并没有改变。总体而言，我们的结果表明，经验可以是比赛结果的一个重要决定因素，即使在短暂的无脊椎动物中也是如此，而经验本身不太可能改变表型与健康的联系。
In the field, phenotypic determinants of competitive success are not always absolute. For example, contest experience may alter future competitive performance. As future contests are not determined solely on phenotypic attributes, prior experience could also potentially alter phenotype–fitness associations. In this study, we examined the influence of single and multiple experiences on contest outcomes in the jumping spider Phidippus clarus. We also examined whether phenotype–fitness associations altered as individuals gained more experience. Using both size-matched contests and a tournament design, we found that both winning and losing experience affected future contest success; males with prior winning experience were more likely to win subsequent contests. Although experience was a significant determinant of success in future contests, male weight was approximately 1.3 times more important than experience in predicting contest outcomes. Despite the importance of experience in determining contest outcomes, patterns of selection did not change between rounds. Overall, our results show that experience can be an important determinant in contest outcomes, even in short-lived invertebrates, and that experience alone is unlikely to alter phenotype–fitness associations.
