Rotifers are critical members of freshwater communities because of their important roles in energy and nutrient cycling. Rotifers have also proven to be valuable models for aging and toxicology studies, and are a key early diverging lineage for understanding the pattern of evolution within the animal clade. Despite this importance, rotifer species remain difficult to identify and few phylogenetic relationships within the clade are well supported. This collaborative effort linking researchers at the University of Texas El Paso, University of Massachusetts Lowell and Ripon College will increase phylogenetic and taxonomic resolution within phylum Rotifera by using a combination of advanced molecular and morphological techniques. This research will result in a new phylogenetic classification for the clade, in addition to insights into the rates of molecular evolution and the rates and drivers of cryptic speciation within the rotifer lineage.The project will provide scientific training focused on rotifer systematics to graduate and undergraduate students at each of the three collaborating institutions. An undergraduate laboratory module, newly designed museum exhibit, and scientific workshops will all help disseminate the results broadly. The public will be able to access an interactive tutorial and key to rotifer species, plus other results from the project via the Encyclopedia of Life website.

轮虫是淡水群落的重要成员，因为它们在能量和养分循环中发挥着重要作用。轮虫也被证明是衰老和毒理学研究的有价值的模型，并且是了解动物进化枝内部进化模式的关键早期分化谱系。尽管如此重要，但轮虫物种仍然难以识别，并且分支内的系统发育关系很少得到充分支持。这项合作将德克萨斯大学埃尔帕索分校、马萨诸塞大学洛厄尔分校和里彭学院的研究人员联合起来，通过结合先进的分子和形态学技术，提高轮虫门的系统发育和分类学分辨率。 除了深入了解轮虫谱系内的分子进化速率以及神秘物种形成的速率和驱动因素之外，这项研究还将为该进化枝带来新的系统发育分类。该项目将为研究生和本科生提供以轮虫系统学为重点的科学培训三个合作机构各自的学生。本科生实验室模块、新设计的博物馆展览和科学研讨会都将有助于广泛传播研究成果。公众将能够通过生命百科全书网站访问交互式教程和轮虫物种的关键，以及该项目的其他结果。
