Ecology, sexual dimorphism, and jumping evolution in anurans

Sexual dimorphism is a common feature of animals, and selection for sexually dimorphic traits may affect both functional morphological traits and organismal performance. Trait evolution through natural selection can also vary across environments. However, whether the evolution of organismal performance is distinct between the sexes is rarely tested in a phylogenetic comparative context. Anurans commonly exhibit sexual size dimorphism, which may affect jumping performance given the effects of body size on locomotion. They also live in a wide variety of microhabitats. Yet the relationships among dimorphism, performance, and ecology remain underexamined in anurans. Here, we explore relationships between microhabitat use, body size, and jumping performance in males and females to determine the drivers of dimorphic patterns in jumping performance. Using methods for predicting jumping performance through anatomical measurements, we describe how fecundity selection and natural selection associ..., This dataset consists of sex identifications, individual linear measurements, body mass, estimates of leg muscle volume of many species obtained from museum specimens, and museum id and tag information. Muscle volumes were estimated using the geometric equations described in Juarez and Adams 2021 Evolutionary Ecology. The dataset was processed by calculating species means from adult male and female individuals. Please see the original manuscript for details on several ways in which the data were filtered., Raw values in museums_morph_FINAL.csv do not represent final values analyzed in the manuscript. Values in museums_volume_FINAL.csv contain individual data from which species means were obtained but please read README_museums_volume_FINAL.csv.txt for more details before using. Some missing values are included, which are accounted for in the analyses as described in the manuscript. The data files may be opened using R or any other software that reads .csv files. The code was written in R.Â性二态性（sexual dimorphism）是动物的普遍特征，针对性二态性状的选择可能同时影响功能形态性状与有机体整体性能。通过自然选择实现的性状演化也会因环境而异。然而，在系统发育比较框架（phylogenetic comparative context）下检验两性间有机体性能演化是否存在差异的研究极少。无尾目（Anurans）动物普遍存在体型大小的性二态性，而体型对运动能力存在影响，因此该性二态性可能作用于跳跃性能。此外，无尾目栖息于多种多样的微生境中。但目前学界针对无尾目类群中，性二态性、运动性能与生态环境三者间的关联仍缺乏充分研究。本研究探讨了雄性与雌性个体的微生境利用、体型大小与跳跃性能之间的关联，以明确跳跃性能性二态模式的驱动因素。我们借助通过解剖学测量预测跳跃性能的方法，阐释了繁殖力选择与自然选择如何……本数据集包含多个物种的个体性别标识、线性测量数据、体重、通过博物馆标本获取的腿部肌肉体积估算值，以及博物馆标本编号与标签信息。肌肉体积的估算参考了Juarez与Adams于2021年发表在《Evolutionary Ecology》中的几何方程。本数据集通过统计成年雄性与雌性个体的物种均值进行处理。有关数据筛选的具体方式，请参阅原始手稿。museums_morph_FINAL.csv中的原始数值并非本研究手稿中最终分析所用的数值。museums_volume_FINAL.csv中的数值包含用于计算物种均值的个体水平数据，但在使用前请务必阅读README_museums_volume_FINAL.csv.txt以获取更多细节。本数据集包含部分缺失值，正如手稿中所述，这些缺失值已在分析中得到妥善处理。数据文件可通过R或其他可读取.csv格式文件的软件打开，本研究的代码亦使用R语言编写。
