动物的交配行为在物种之间和物种内都是非常不同的。我们研究了莱奥布宁收割者交配行为的变化，这些行为显示出生殖器特征的高度多样性，这些特征被预测为与行为多样性的模式相对应。我们对来自四个地点的六种莱奥布宁进行了交配试验，并测量了一部分个体的体型。我们详细地描述了交配行为--为大多数物种提供了第一个正式描述--并检查了物种间和物种内在体型和行为上的差异。北方种群的个体较小。此外，我们发现了物种和种群特有的行为，交配的不同阶段在时间和成功方面的高度差异，以及高恢复率。然而，我们没有发现行为和形态变化之间的相关性。Leiobunine收割机为了解性别选择的多种机制和交配行为的地理多样性提供了一个极好的系统。
Mating behaviour is highly diverse in animals both among and within species. We examine variation in mating behaviour in leiobunine harvestmen, which show high diversity in genitalic traits that are predicted to correspond to patterns of behavioural diversity. We ran mating trials for six species of leiobunine from four locations, and measured body size for a subset of individuals. We described mating behaviour in detail-providing the first formal description for most species-and examined variation inter-and intraspecific in body size and behaviour. Individuals were smaller in northern populations. Furthermore, we found species-and population-specific behaviours, high variation in the timing and success of different stages of mating, and high remating rates. However, we found no correlation between behavioural and morphological variation. Leiobunine harvestmen offer an excellent system for understanding multiple mechanisms of sexual selection and geographic diversification of mating behaviour.
