不同的病毒和它们的宿主通过复杂的感染网络相互联系，这被认为会影响生态和进化过程，但感染网络结构的基本原理还没有得到很好的理解。在这里，我们专注于网络的维度，以及它如何在37个网络的病毒感染真核浮游植物和细菌的变化。我们发现维度通常非常低，大多数网络都是一维或二维的，尽管维度随着网络的丰富度而增加，这表明自然系统的真实维度更高。低维网络通常表现出病毒之间的宿主划分和宿主范围的嵌套性的混合。感染细菌和感染真核生物的病毒的网络具有相似的维度分布和嵌套的普遍性，表明网络结构的基本原理在生命领域和不同的病毒谱系中是相似的。许多感染网络的相对简单性表明，共同进化动力学往往是由数量不多的潜在机制驱动的。
Diverse viruses and their hosts are interconnected through complex networks of infection, which are thought to influence ecological and evolutionary processes, but the principles underlying infection network structure are not well understood. Here we focus on network dimensionality and how it varies across 37 networks of viruses infecting eukaryotic phytoplankton and bacteria. We find that dimensionality is often strikingly low, with most networks being one‐ or two‐dimensional, although dimensionality increases with network richness, suggesting that the true dimensionality of natural systems is higher. Low‐dimensional networks generally exhibit a mixture of host partitioning among viruses and nestededness of host ranges. Networks of bacteria‐infecting and eukaryote‐infecting viruses possess comparable distributions of dimensionality and prevalence of nestedness, indicating that fundamentals of network structure are similar among domains of life and different viral lineages. The relative simplicity of many infection networks suggests that coevolutionary dynamics are often driven by a modest number of underlying mechanisms.
