Our understanding of the ecological drivers that control community structure of benthic rotifers is poorly known. By reviewing 21 papers on freshwater benthic rotifers we compiled an inventory of an additional 258 species, 27 genera, and six families not previously listed in the review of benthic, lotic rotifers by Ricci and Balsamo (Freshw Biol 44:15–28, 2000). This raises the number of reported benthic species to 416, ~ 23% of all rotifers. Using selected papers within our dataset we tested two hypotheses: (1) Within lakes of different trophic state benthic rotifer communities differ in their species composition and (2) because rotifer trophi types reflect strong specificity for certain foods, there is a difference in the distribution of trophi types in lakes of different trophic state. We found that the trophic state of water bodies influences species composition of benthic rotifers, but there was no significant difference in the distribution of their trophi types. To aid in understanding community assembly of benthic rotifers, we provide a list of knowledge gaps that future studies could address.

底栖轮虫群落结构与湖泊营养状态的关系的荟萃分析

我们对控制底栖轮虫群落结构的生态驱动力的了解很少。通过审查有关淡水底栖轮虫的21篇论文,我们编制了一份清单,列出了另外258种,27属和6个以前未在Ricci和Balsamo的底栖轮虫轮虫评述中列出的家族(Freshw Biol 44:15-28,2000) 。这使报告的底栖物种数量增加到416,约占所有轮虫的23%。使用我们数据集中的选定论文,我们检验了两个假设:(1)在营养状态不同的底栖轮虫群落中,其物种组成有所不同;(2)由于轮枝菌的营养类型反映了对某些食物的强烈特异性,分布有所不同不同营养状态的湖泊中营养类型的变化 我们发现水体的营养状态影响底栖轮虫的物种组成,但其营养类型的分布没有显着差异。为了帮助理解底栖轮虫的社区聚集,我们提供了未来研究可以解决的知识空白清单。
