潜在相互作用物的空间分布对所有合作生物的社会进化至关重要。然而，在与社会互动最相关的尺度上，微生物亲缘歧视的地理学却知之甚少。在这里，我们解决了在小的空间尺度上，在当地人口的模式合作细菌粘球菌的社会身份和遗传相关性的microphoneography，在整个扩散的潜力是高的。使用两个标准的相关性-殖民地合并的兼容性在合作运动和DNA序列相似性在高度多态位点，我们发现，相关性大大降低空间距离，即使在最小的尺度过渡。社会相关性和遗传相关性在微米尺度下的单个子实体内是最大的，但在毫米尺度下的相邻子实体之间已经低得多。发现厘米级样本的遗传相关性更低，而社会同种异型相关性仅在米级进一步下降，在米级和超过米级时，随机抽样的分离株之间的社会或遗传身份的概率实际上为零。因此，在M. xanthus，高相关补丁形成了丰富的马赛克不同的社会同种异型跨越子实体社区在毫米尺度和超越。即使是在相邻群体之间迁移很短距离的个人也会经常遇到同种异型的同种异型和领土亲属歧视，这可能会深刻影响当地迁移的空间动态。最后，我们还发现，种内系统发育分析的系统发育范围可以影响空间结构的检测，因为在分支特异性分析中明显的一些模式被所有菌株的同时分析所掩盖。
The spatial distribution of potential interactants is critical to social evolution in all cooperative organisms. Yet the biogeography of microbial kin discrimination at the scales most relevant to social interactions is poorly understood. Here we resolve the microbiogeography of social identity and genetic relatedness in local populations of the model cooperative bacterium Myxococcus xanthus at small spatial scales, across which the potential for dispersal is high. Using two criteria of relatedness—colony‐merger compatibility during cooperative motility and DNA‐sequence similarity at highly polymorphic loci—we find that relatedness decreases greatly with spatial distance even across the smallest scale transition. Both social relatedness and genetic relatedness are maximal within individual fruiting bodies at the micrometre scale but are much lower already across adjacent fruiting bodies at the millimetre scale. Genetic relatedness was found to be yet lower among centimetre‐scale samples, whereas social allotype relatedness decreased further only at the metre scale, at and beyond which the probability of social or genetic identity among randomly sampled isolates is effectively zero. Thus, in M. xanthus, high‐relatedness patches form a rich mosaic of diverse social allotypes across fruiting body neighbourhoods at the millimetre scale and beyond. Individuals that migrate even short distances across adjacent groups will frequently encounter allotypic conspecifics and territorial kin discrimination may profoundly influence the spatial dynamics of local migration. Finally, we also found that the phylogenetic scope of intraspecific biogeographic analysis can affect the detection of spatial structure, as some patterns evident in clade‐specific analysis were masked by simultaneous analysis of all strains.
