2007年4月，在古老的喀喀湖发现了一种全球入侵的淡水腹足类物种--尖尾轮虫的重要种群。种群是在秘鲁一侧的Chucuito(Bahia De Puno)附近发现的，靠近普诺大学水产养殖设施的一艘船。在0~2m水深的大型植物上发现了大量的Physias，Physa acuta与Heleobia andicola物种复合体的成员以及Heleobia otorni、Biomphalaria andecola和Unancylus crequi联系在一起。通过形态学和分子生物学方法对其进行了种属鉴定。我们讨论了引入的方式，并对这种全球入侵者对喀喀湖特有的腹足动物区系的潜在影响提出了警告。
A vital population of Physa acuta, a globally invasive species of freshwater gastropods was dicovered in ancient Lake Titicaca in April 2007. The population was found near Chucuito (Bahia de Puno) on the Peruvian side in close proximity to a boat landing of the aquaculture facility of the University of Puno. Physids occured in great abundances at this site on macrophytes in depths from 0 to 2 m. Physa acuta was associated with members of the Heleobia andicola species complex as well as with Heleobia otorni, Biomphalaria andecola, and Uncancylus crequi. Species identity was confirmed by morphological and molecular methods. We discuss the mode of introduction and raise a cautionary note on the potential impact of this global invader on the endemic gastropod fauna of ancient Lake Titicaca.
