我们收集了有关在南极洲和Subanaitica轮虫发生的分类学信息，产生了一个数据库，其中包含自遥远的南方开始研究探险以来发表的所有93篇关于该地区的论文中的1100多条记录。通过文献综述，我们概述了南极轮虫研究的历史。然后，使用该数据库，我们解决了在南极洲和Subanaustica轮虫物种丰富度的地理模式的具体问题。我们强调了一个复杂的情况下，地区和纬度梯度之间的差异，不同的采样偏差的问题。单殖体轮虫的物种数量似乎随着绝对纬度的增加而减少，而蛭形轮虫的物种数量通常随着绝对纬度的增加而增加。
We gathered taxonomic information regarding the occurrence of rotifers in Antarctica and Subantarctica, producing a database of more than 1100 records from all 93 papers published on the region since the start of research expeditions in the far South. From this literature review, we outline a history of rotifer research in Antarctica. Then, using the database, we address specific questions on biogeographic patterns in species richness in rotifers in Antarctica and Subantarctica. We highlight a complex scenario of differences between areas and latitudinal gradients, differentially affected by problems in sampling bias. The number of species of monogonont rotifers seems to decrease with increasing absolute latitudes, whereas the number of species of bdelloid rotifers generally increases with increasing absolute latitudes.
