Lake ecosystems contain numerous habitats, such as the relatively homogeneous pelagial, as well as many different subhabitats in the littoral zone. Among rotifer communities inhabiting the littoral zone are those living in organic sediments (epipelon), on submerged stones (epilithon), among sand grains (hydropsammon), on animals (epizoon), on submerged branches and twigs (epixylon) and on macrophytes (epiphyton). The aim of this work was to explain differences in species richness among rotifer communities inhabiting these subhabitats. Qualitative and quantitative analyses of the structure and diversity of rotifer species were based on studies carried out in the summers of 2009–2020 in lakes in northeastern Poland. The analysis of the structure and density of rotifer species inhabiting different lake subhabitats suggests that although the communities are subject to similar ecological characteristics, there are marked differences in the species richness and diversity of the communities. A characteristic feature is the presence of species sharing subhabitats and species assigned to only one habitat type.

湖泊生态系统包含许多栖息地，例如相对均质的中上层，以及沿岸带的许多不同的亚生境。居住在沿海地区的轮虫群落中有以下生物：生活在有机沉积物中（pipe虫），被淹没的石头（e），沙粒（水ps），动物（ep），被淹没的树枝和细枝（（）和大型植物（表藻）。 ）。这项工作的目的是解释居住在这些亚生境的轮虫群落之间物种丰富度的差异。对轮虫物种结构和多样性的定性和定量分析是基于2009-2020年夏季在波兰东北部湖泊中进行的研究。对生活在不同湖泊亚生境中的轮虫物种的结构和密度的分析表明，尽管该群落具有相似的生态特征，但群落的物种丰富度和多样性存在明显差异。一个特征是存在共享亚生境的物种和仅分配给一种生境类型的物种。
