动物适应变暖的能力将取决于对温度敏感的性状的进化潜力。测量各种热敏感性状的数量遗传学的研究数量稳步增加，但是，还没有研究调查求偶性状的热敏感性的数量遗传学。由于求偶通常在交配之前，这些特征对变暖的反应能力可能会影响繁殖，从而影响种群的持久性。在这里，我们使用经典的数量遗传育种设计，估计各方面的求偶行为的热敏感性的遗传力Enchenopa binotata。我们为男性和女性生成了个体水平的热求偶活动曲线，并测量了求偶活动的热敏感性的遗传变异水平。我们发现低遗传力与95%的可信区间，不接近零的大多数性状。描述耐热性的性状的遗传变异水平最高。我们还发现了一些证据，表明性别内而非性别间的性状之间存在遗传相关性。总之，我们的研究结果表明，温度的范围内，这些treehoppers积极法院可以演变，虽然目前还不清楚适应是否可以发生足够快，以匹配的速度warming.AbstractIndividually标记的女性treehoppers，Enchenopa binotata，在他们的家乡植物测试之前。
The ability of animals to adapt to warming will depend on the evolutionary potential of thermally sensitive traits. The number of studies measuring the quantitative genetics of a wide variety of thermally sensitive traits has steadily increased; however, no study has yet investigated the quantitative genetics of thermal sensitivity for courtship traits. Since courtship often precedes mating, the ability of these traits to respond to warming may impact reproduction and therefore population persistence. Here, we use classic quantitative genetics breeding design to estimate heritability of various aspects of the thermal sensitivity of courtship behaviours in the treehopper Enchenopa binotata. We generated individual‐level thermal courtship activity curves for males and females and measured levels of genetic variation in the thermal sensitivity of courtship activity. We found low heritability with 95% credible intervals that did not approach zero for most traits. Levels of genetic variation were highest in traits describing thermal tolerance. We also found some evidence for genetic correlations between traits within but not across sexes. Together, our results suggest that the range of temperatures over which these treehoppers actively court can evolve, although it remains unclear whether adaptation can happen quickly enough to match the speed of warming.AbstractIndividually marked female treehoppers, Enchenopa binotata, on their home plant prior to testing.
