The degree to which widely accepted generalizations about food web structure apply to natural communities was determined through examination of 50 pelagic webs sampled consistently with even taxonomic resolution of all trophic levels. The fraction of species in various trophic categories showed no significant overall trends as the number of species varied from 10 to 74. In contrast, the number of links per species increased fourfold over the range of species number, suggesting that the link-species scaling law, defined on the basis of aggregated webs, does not reflect a real ecological trend.
通过检查 50 个浮游生物网，我们以所有营养层次的均匀分类分辨率一致地采样，以确定广泛接受的食物网结构概括在多大程度上适用于自然群落。各种营养类别中的物种比例在物种数量从 10 到 74 变化时没有显示出显著的总体趋势。相比之下，每个物种的链接数量在物种数量范围内增加了四倍，这表明基于聚合网络定义的链接-物种标度定律并不能反映真实的生态趋势。
