Tree swallow pair similarity dataset

For this project, we studied the cloacal bacterial communities of a socially monogamous yet genetically polygynous songbird, the tree swallow (Tachycineta bicolor), in eastern North America. We address two questions: (1) do the cloacal bacterial communities differ between female and male tree swallows within a population? And (2) do pair-bonded social partners exhibit more similar cloacal bacterial communities than expected by chance?

本研究针对北美东部地区一种兼具社会单配制与遗传多配制特征的鸣禽——树燕（Tachycineta bicolor）的泄殖腔细菌群落（cloacal bacterial communities）开展了系统性探究。本研究旨在解答两项核心科学问题：其一，同一种群内雌性与雄性树燕的泄殖腔细菌群落是否存在显著差异？其二，结对的社交配偶对的泄殖腔细菌群落相似性是否显著高于随机预期水平？
