在加拿大新斯科舍省杰克湖沿岸地区检查了微甲壳动物在水体、沉积物和不同大型植物物种中的分布。大量的微甲壳类动物与大型植物一起出现，表明在未来的微甲壳类动物数量、生物量和产量研究中，该栖息地应受到更多关注。沉积物、大型植物和水体样本中不同微甲壳类动物的相对丰度差异很大。尽管微型甲壳类动物的物种组成在大型植物群体之间有所不同，但无法证明每克绝对数量的一致差异。杰克湖深层附生微甲壳动物群落结构也存在差异。很少有附生和底栖微甲壳动物每天迁移到水体中。
The distribution of microcrustacea in the water column, sediments and on different macrophyte species was examined in the littoral zone of Jack Lake, Nova Scotia, Canada. Large numbers of microcrustacea occurred in association with macrophytes, suggesting that this habitat should receive greater attention in future studies of microcrustacean numbers, biomass, and production. The relative abundance of different microcrustacea varied considerably among sediments, macrophytes and water column samples. Although microcrustacean species composition differed among macrophyte groups, consistent differences in absolute numbers per gram could not be demonstrated. Epiphytic microcrustacean community structure also varied among depth strata in Jack Lake. Few epiphytic and benthic microcrustacea migrated into the water column on a diurnal basis.
