In this study, we compared the efficacy of geometric morphometric techniques, including outlines and landmark-based approaches, to support the differentiation of Trichodina bellottii from three co-occurring killifish species. Both methods were able to differentiate trichodinids from different host species. However, discriminat analyses and MANOVA results based on landmarks had greater accuracy possibly because these analyses only provide information on certain points defined by the researcher, while the analyses based on outlines take into account points with less taxonomic information.
在这项研究中，我们比较了几何形态测量技术的效果，包括轮廓和基于地标两种方法，以支持区分三种植鲷科鱼类中的贝氏毛口虫。两种方法都能够区分毛口虫与不同的宿主物种。然而，基于地标进行的判别分析和 MANOVA 结果可能更准确，因为这些分析只提供研究人员定义的某些点的信息，而基于轮廓的分析则考虑了具有较少分类信息的点。
