资源简介:
Gregarious species must distinguish group members from non-group members. Olfaction is important for group recognition in mammals but rarely studied in birds, despite birds using olfaction in social contexts from species discrimination to kin recognition. Olfactory-based recognition requires that groups have a signature odour, so we tested for preen oil and feather chemical similarity among group-living smooth-billed anis (Crotophaga ani). Physiology affects body chemistry, so we also tested for an effect of egg-laying competition, as a proxy for reproductive status, on female chemical similarity. Finally, the fermentation hypothesis for chemical recognition posits that host-associated microbes drive host odour, so we tested for covariation between ani chemicals and microbiota. Group members were more chemically similar than non-group members, regardless of body region, demonstrating that gregarious bird species can have group chemical signatures. Females in groups with less egg-laying ..., See README.md and main article text for details., R, RStudio, Excel, Notepad (or other text reader)., Reference Information

群居物种必须区分群体成员与非群体成员。嗅觉在哺乳类的群体识别中发挥重要作用,但针对鸟类的相关研究却相对匮乏——尽管鸟类在从物种识别到亲缘识别的各类社会情境中均会运用嗅觉。基于嗅觉的识别要求群体具备特征气味,因此我们针对群居的滑嘴犀鹃(Crotophaga ani)展开实验,检测其尾脂油(preen oil)与羽毛的化学相似性。生理机能会影响机体化学组成,因此我们同时检测了作为繁殖状态替代指标的产卵竞争对雌性个体化学相似性的影响。最后,化学识别的发酵假说指出,宿主共生微生物会塑造宿主气味,因此我们检测了滑嘴犀鹃的化学物质与微生物群(microbiota)之间的共变关系。实验结果显示,无论身体部位为何,群体成员的化学相似性均显著高于非群体成员,这表明群居鸟类可形成群体特征化学信号。产卵竞争较弱的群体中的雌性……详见README.md与正文文本。
