Oithona similis belongs to the Copepoda Cyclopoida. It is highly abundant throughout many parts of the world ocean and supposed to be a cosmopolitan species. Aim of this project is to find out whether O. similis, a key species in the three chosen study areas (Arctic, Antarctic and North Sea), is indeed a cosmopolitan species. A further goal is a better understanding of its life cycle (or in case there are cryptic species of their life cycles) including feeding habits and generation times of the developmental stages, as well as the combined role of food resources and temperature within its/their life cycle/s. The literature is full of contradictory information on all aspects of the biology of O. similis. The main goal will be to find the reasons for these contradictions, whether they are caused by the great biological and/or genetical flexibility of the species or by the fact that there are several cryptic species. Such species may be very stenoecious as indicated by their similar or even identical morphology. This will be studied by using genetical and morphological techniques. The results will then dictate the further procedure. In case of a cosmopolitan species it will be examined whether morphologically different populations exist within each of the three study areas. In the other case it will be differentiated between the single cryptic species.

Oithona Similis属于Copepoda Cyclopoida。它在世界许多地区都非常丰富，应该是一种国际化的物种。该项目的目的是找出三个选择的研究区域（北极，南极和北海）的主要物种O. similis是否确实是一种国际化的物种。另一个目标是更好地理解其生命周期（或者如果存在生命周期的神秘物种），包括喂养习惯和发育阶段的发电时间，以及食品资源和温度在其/其生命周期内的综合作用。文献充满了有关O. similis生物学各个方面的矛盾信息。主要目标是找到造成这些矛盾的原因，无论它们是由该物种的巨大生物学和/或遗传灵活性引起的，还是由于有几种隐性物种而引起的。这种物种可能非常敏捷，如它们相似甚至相同的形态所表明的那样。这将通过使用遗传和形态学技术来研究。结果将决定进一步的程序。如果是国际化的物种，将检查三个研究领域中的每个人群中是否存在形态学不同的人群。在另一种情况下，它将在单个隐性物种之间进行区分。
