Data and R code for "Functional traits explain waterbirds’ host status, subtype richness, and community-level infection risk for avian influenza"

Species functional traits can influence several processes of pathogen transmission and, consequently, affect species’ host status, pathogen diversity, and community-level infection risk. In this study, we investigated, for 143 European waterbird species, the effects of functional traits on host status and pathogen diversity (subtype richness) for the avian influenza virus at the species level. We also explored the association between functional diversity and HPAI H5Nx occurrence at the community level for the 2016/17 and 2021/22 epidemics. This dataset contains datasets and R code files to replicate our analysis and results. Supplementary Dataset 1 is the data to replicate our analysis for host status and pathogen diversity (subtype richness) at the species level. Supplementary Dataset 2 is the data to replicate the analysis for the association between functional diversity and HPAI H5Nx occurrence at the community level. Supplementary Datasets 3 and 4 are the description data for Figure 1B and Figure 3 in the manuscript. Supplementary Codes 1 to 5 contain the R code to reproduce the analysis and figures. Supplementary phylogenetic birdtree contains the Hackett backbone phylogenetic tree of avian species.

物种功能性状可影响病原体传播的多个过程，进而调控物种的宿主状态、病原体多样性及群落水平感染风险。本研究以143种欧洲水鸟为研究对象，在物种层面探究了功能性状对禽流感病毒宿主状态及病原体多样性（亚型丰富度）的影响；同时针对2016/2017与2021/2022年的禽流感疫情，在群落层面分析了功能多样性与高致病性禽流感（Highly Pathogenic Avian Influenza, HPAI）H5Nx暴发的关联。本数据集包含可复现本研究分析与结果的数据集及R代码文件：补充数据集1用于复现物种层面宿主状态与病原体多样性（亚型丰富度）的相关分析；补充数据集2用于复现群落层面功能多样性与高致病性禽流感H5Nx暴发的关联分析；补充数据集3与4分别对应论文中图1B与图3的描述性数据；补充代码1至5包含复现本研究分析与图表所需的R代码；补充鸟类系统发育树数据集则包含鸟类物种的Hackett主干系统发育树。
