化学通讯几乎支撑着脊椎动物社会生活的所有方面,但由于其高度复杂的机制基础,人们对化学通讯仍然知之甚少。因此,我们使用皮肤拭子的化学指纹识别和遗传分析来探索在殖民繁殖的南极海狗中可能构成母子识别的化学线索。通过对来自两个不同菌落的母子对进行采样,使用各种统计方法并对一大组微卫星位点进行基因分型,我们表明菌落成员资格、母子相似性、杂合性和遗传相关性都是化学编码的。此外,母亲和后代之间的化学相似性反映了遗传和环境影响的结合,前者部分由类似于已知信息素的物质编码。我们的研究结果揭示了化学指纹中包含的信息的多样性,对于理解母子交流、亲属识别和配偶选择具有重要意义。
Chemical communication underpins virtually all aspects of vertebrate social life, yet remains poorly understood because of its highly complex mechanistic basis. We therefore used chemical fingerprinting of skin swabs and genetic analysis to explore the chemical cues that may underlie mother–offspring recognition in colonially breeding Antarctic fur seals. By sampling mother–offspring pairs from two different colonies, using a variety of statistical approaches and genotyping a large panel of microsatellite loci, we show that colony membership, mother–offspring similarity, heterozygosity, and genetic relatedness are all chemically encoded. Moreover, chemical similarity between mothers and offspring reflects a combination of genetic and environmental influences, the former partly encoded by substances resembling known pheromones. Our findings reveal the diversity of information contained within chemical fingerprints and have implications for understanding mother–offspring communication, kin recognition, and mate choice.
