Data from Mirror Lake, New Hampshire, are used to construct the first quantitative description of the size structure of a freshwater benthic animal community. Size spectra of the benthic animal community, whether expressed as animal density, biomass, species richness, or assimilation, are generally unimodal. These spectra are strikingly different from the characteristically bimodal size spectra reported for marine benthic communities. There is no indication in these size spectra that the meiofauna and macrofauna are distinct ecological entities in Mirror Lake, as has been suggested for marine benthic communities.
来自新罕布什尔州镜湖的数据被用于构建淡水底栖动物群落大小结构的首个定量描述。底栖动物群落的大小谱，无论以动物密度、生物量、物种丰富度还是同化作用来表示，通常都是单峰的。这些谱与报道的海洋底栖群落典型的双峰大小谱显著不同。在这些大小谱中，没有迹象表明小型底栖动物和大型底栖动物在镜湖是不同的生态实体，而在海洋底栖群落中曾有此说法。
