Lifetime reproductive success and fitness estimates of long-tailed tits in the Rivelin Valley, Sheffield, UK, from 1994-2019

Dataset comprising data on the lifetime reproductive success (LRS) of 879 individually marked long-tailed tits Aegithalos caudatus, a cooperatively breeding passerine. LRS is measured in terms of the number of local recruits into the breeding population in the study area, controlling for fledgling sex and extra-pair paternity. LRS data are then partitioned into direct and indirect fitness components, quantified as genetic equivalents. Partitioning of fitness follows Hamilton’s definition of inclusive fitness: (a) direct fitness is measured as the production of offspring, stripped of the social effect of helpers on productivity; (b) indirect fitness is calculated from the mean marginal effect of a helper on productivity, adjusted for helper relatedness. Inclusive fitness is calculated by summing direct and indirect fitness. Full details about this dataset can be found at https://doi.org/10.5285/0e55f507-e5bd-4678-a5ea-8c3ffb62d3ac

本数据集包含关于879只个体标记的长尾山雀（Aegithalos caudatus）的终身繁殖成功率（LRS）数据，该物种为合作繁殖的鸣禽。终身繁殖成功率以研究区域内加入繁殖种群的本地幼鸟数量来衡量，同时控制幼鸟性别和额外配对父权。LRS数据随后被划分为直接和间接的适应性成分，并以遗传等价物进行量化。适应性成分的划分遵循汉密尔顿的包容性适应性定义：（a）直接适应性以后代产生量来衡量，去除了助手对生产力的社会影响；（b）间接适应性通过计算助手对生产力边际效应的平均值来确定，并调整了助手的相关性。包容性适应性通过直接和间接适应性的总和来计算。关于本数据集的详细信息可查阅https://doi.org/10.5285/0e55f507-e5bd-4678-a5ea-8c3ffb62d3ac。
