Kellicottia bostoniensis is a rotifer species originating from North America, with numerous reports documenting its spread to Europe and South America. Meanwhile, in Asia, the occurrence of this non-native has been scarcely documented, but presence was recently reported Korea 2020. In Korea, close geographic proximity artificial reservoirs within small area expected make region vulnerable K. bostoniensis. Therefore, it deemed necessary study spatio-temporal distribution bostoniensis, which appears have extensively proliferated across region, relationship environmental factors. We analyzed response factors aimed compare patterns those potential competitor predator groups, were classified based on functional group approach. This study, conducted 12 lakes located under similar climatic conditions, revealed that variables representing trophic state differed groups. The sites, encompassing wide range states oligotrophic hypereutrophic, various survey periods, well-suited for examining these relationships. Furthermore, when TSI calculated abundance competitors proportional TSI. contrast, exhibited higher abundances mesotrophic lower eutrophic environments, distinguished competitors. Our results indicate impact introduced native communities minimal, while resistance through biological filter interactions ineffective against species. provides key evidence explaining widespread continents.
