水囊苔虫是一种入侵性苔藓虫属，容易被污染的容器传播。我们研究了细胞色素c氧化酶亚基I单倍型从引进的人口在美国太平洋海岸线调查地理分离的物种和/或单倍型。在加州，W. subtorquata类群又分为3个亚类群：W. subtorquata分支A和B以及W.“新的SP "。W. subtorquata分支A和B在加州南部的Point Conception（一个公认的地理边界）以南是常见的，而在更北的地方，W. subtorquata进化枝A和W. n. sp.是常见的。南加州地区也有形态上不同的物种W.在澳大利亚南部和夏威夷也有发现; COI变异表明在这些引进中有共同的祖先来源。在不同的海岸线上的Watersipora复杂的谱系的分布被证明是温度相关的。因此，基于温度的适应可能在确定入侵模式中发挥关键作用。
Watersipora is an invasive genus of bryozoans, easily dispersed by fouled vessels. We examined Cytochrome c oxidase subunit I haplotypes from introduced populations on the US Pacific coastline to investigate geographic segregation of species and/or haplotypes. In California, the W. subtorquata group fell into three major sub-groups: W. subtorquata clades A and B and W. “new sp.”. W. subtorquata clades A and B were common in southern California south of Point Conception, a recognized biogeographic boundary, whereas further north, W. subtorquata clade A and W. n. sp. were frequent. The southern California region also had colonies of a morphologically distinct species, W. arcuata, also found in southern Australia and Hawaii; COI variation indicates a common ancestral source(s) in these introductions. The distribution of Watersipora-complex lineages on different coastlines is shown to be temperature correlated. Accordingly, pre-exisitng temperature-based adaptations may play a key role in determining invasion patterns.
