温度影响着广泛的交配行为，特别是在体温与环境温度相似的变温生物中。在这里，我们测试的热变化的影响precopulatory和交配行为的harvesterLeiobunum politumWeed 1889年，这属于一组通常被称为爸爸长腿。我们在交配季节（18-34°C）的田间常见温度下进行了2年的单一选择交配试验。我们测试了温度如何影响移动、尝试交配和成功交配的可能性以及交配持续时间。交配是最高的在低到中等温度，和温度时，交配率峰值发生不同年份。在大范围的温度范围内，L. politum被发现交配，反映了该领域的热变化性和这种迷人动物交配行为的灵活性。
Temperature impacts a wide range of mating behaviors, particularly in ectothermic organisms that tend to have body temperatures similar to ambient thermal conditions. Here, we test the effects of thermal variation on precopulatory and copulatory behavior in the harvesterLeiobunum politumWeed 1889, which belongs to the group commonly known as daddy longlegs. We ran single choice mating trials across temperatures commonly experienced in the field during the mating season (18–34°C) for 2 years. We tested how temperature affected the likelihood to move, attempt to mate, and successfully mate, as well as the duration of copulation. Mating was highest at low to intermediate temperatures, and the temperature at which peak mating rates occurred varied across years. The wide range of temperatures across whichL. politumis found to mate reflects thermal variability in the field and the flexibility in mating behavior in this fascinating animal.
