Evolutionary lability of sexual selection and its implications for speciation and macroevolution

Sexual selection is widely hypothesized to facilitate speciation and phenotypic evolution, but evidence from comparative studies has been mixed. Many previous studies have relied on proxy variables to quantify the intensity of sexual selection, raising the possibility that inconclusive results may reflect, in part, the imperfect measurement of this evolutionary process. Here, we test the relationship between phylogenetic speciation rates and indices of the opportunity for sexual selection drawn from populations of 82 vertebrate taxa. These indices provide a much more direct assessment of sexual selection intensity than proxy traits and allow straightforward comparisons among distantly related clades. We find no correlation between the opportunity for sexual selection and speciation rate, and this result is consistent across many complementary analyses. In addition, widely used proxy variables – sexual dimorphism and dichromatism – are not correlated with indices employed here. Moreover,..., Meta-analytic procedure used for data collection
Estimates of the opportunity for sexual selection and Bateman gradients were obtained after an extensive search in the literature that follows meta-analytic procedures (see more details in Macedo-Rego et al 2024. 
While screening the literature, studies were selected whether they provided at least one estimate of φIs or φIf and one estimate of φI for a given sex (see main text). The search was performed in two databases: ISI Web of Science (all databases) and Scopus, and its step-by-step PRISMA design (see Nakagawa et al, 2017) is illustrated in Supplementary figure 2. The following keywords were used:\"reproductive success\" AND \"mating success\" OR \"fitness\" AND \"mating success\" OR \"paternity\" AND \"mating success\" OR \"offspring\" AND \"mating success\" OR \"litter\" AND \"mating success\" OR \"fertilization success\" AND \"mating success\" OR \"breeding success\" AND \"mating success\" OR \"fecundity\" AND \"mating success\" OR \"reproductive rate\" AND \"matin..., , # Data from: Evolutionary lability of sexual selection and its implications for speciation and macroevolution

## 数据集说明
性选择（sexual selection）被广泛假说为能够推动物种形成（speciation）与表型演化（phenotypic evolution），但比较研究（comparative study）提供的证据却莫衷一是。既往诸多研究均依赖替代变量（proxy variable）量化性选择强度，这使得研究结果的不确定性可能部分源于该演化过程的测量不够精准。
本研究针对82个脊椎动物类群（vertebrate taxa）的种群，检验了系统发育（phylogenetic）物种形成速率与性选择机会指数之间的关联。相较于替代性状，此类指数能够更直接地评估性选择强度，同时也便于在亲缘关系较远的演化支（clade）之间进行直接比较。
本研究未发现性选择机会与物种形成速率之间存在关联，且该结果在多项补充分析中均保持一致。此外，学界广泛使用的替代变量——性二态性（sexual dimorphism）与色彩二态性（dichromatism）——与本研究采用的指数亦无相关性。此外，…… 用于数据收集的元分析（meta-analytic）流程
性选择机会与贝特曼梯度（Bateman gradients）的估算值通过遵循元分析流程的大规模文献检索获得（详细内容参见Macedo-Rego等人2024年的研究）。
在文献筛选阶段，我们选取了至少针对某一性别提供了φIs或φIf估算值，以及至少一个φI估算值的研究（详见正文）。本次检索共覆盖两个数据库：ISI Web of Science（全库）与Scopus，其遵循PRISMA声明的分步流程详见补充材料图2（参见Nakagawa等人2017年研究）。
本次检索采用的关键词组合为："reproductive success" AND "mating success" OR "fitness" AND "mating success" OR "paternity" AND "mating success" OR "offspring" AND "mating success" OR "litter" AND "mating success" OR "fertilization success" AND "mating success" OR "breeding success" AND "mating success" OR "fecundity" AND "mating success" OR "reproductive rate" AND "mating success……，# 数据来源：《性选择的演化不稳定性及其对物种形成与宏观演化的启示》
