Heritability of cognitive performance in wild Western Australian magpies

Individual differences in cognitive performance can have genetic, social and environmental components. Most research on the heritability of cognitive traits comes from humans or captive non-human animals, whilst less attention has been given to wild populations. Western Australian magpies (Gymnorhina tibicen dorsalis, hereafter magpies) show phenotypic variation in cognitive performance, which affects reproductive success. Despite high levels of individual repeatability, we do not know whether cognitive performance is heritable in this species. Here, we quantify broad-sense heritability of associative learning ability in a wild population of Western Australian magpies. Specifically, we explore whether offspring associative learning performance is predicted by maternal associative learning performance, or by the social environment (group size) when tested at three time points during the first year of life. We found no significant relationship between maternal and offspring associative le..., , , # Heritability of cognitive performance in wild Western Australian magpies

Dataset contains the R script, data files (.csv) for all analyses and the supplementary material.

## Description of the data and file structure

Each data file is labelled according to the testing period (100 for 100 days post-fledging, 200 for 200 days post-fledging etc). Data files (.csv) labelled 100 full, 200 full and 300 full contain the full data set and these were used for initial exploratory analyses (presented in the supplementary material). Data files (.csv) labelled 100, 200 and 300 contain the data subset for which maternal scores were available and these were used for GLMMs in the main text. Data files (.csv) labelled Regression100, Regression200 and Regression300 were used for broad-sense heritability estimates. This dataset contains a mid-offspring value per female (obtained by averaging offspring scores where multiple scores were obtained from the same mother).

认知表现的个体差异可由遗传、社会与环境因素共同构成。当前有关认知性状遗传力的研究多聚焦于人类或圈养非人动物，对野生种群的关注相对匮乏。西澳鹊（Gymnorhina tibicen dorsalis，后文简称鹊）的认知表现存在表型变异，且该变异会影响其繁殖成功率。尽管此前研究已证实该物种认知表现具有较高的个体重复性，但我们仍不清楚其认知表现是否具有可遗传性。本研究量化了野生西澳鹊种群联想学习能力的广义遗传力（broad-sense heritability）。具体而言，我们在幼鸟出生后第一年的三个时间点开展测试，探究后代的联想学习表现是否可通过母本的联想学习成绩，或是社会环境（群体规模）进行预测。本研究未发现母本与后代的联想学习成绩间存在显著关联……# 野生西澳鹊认知表现的遗传力

本数据集包含所有分析所用的R脚本、数据文件（.csv格式）以及补充材料。

## 数据与文件结构说明
所有数据文件均以测试周期命名（例如100代表离巢后100天，200代表离巢后200天，以此类推）。命名为100 full、200 full与300 full的.csv数据文件包含完整数据集，用于初始探索性分析（相关结果已收录于补充材料）。命名为100、200与300的.csv数据文件为子集数据，仅包含可获取母本成绩的样本，用于正文中广义线性混合模型（Generalized Linear Mixed Models，简称GLMMs）的构建与分析。命名为Regression100、Regression200与Regression300的.csv数据文件则用于广义遗传力的估算。本数据集为每位母本提供了一个后代平均得分（即对同一母本的多个后代成绩取平均值得到）。
