在伊利湖的深水区发现一种形态上不同的dreissenid贻贝，这表明在五大湖中存在第三种dreissenid贻贝，或者存在一种以前未知的现有dreissenid物种的形态表型。我们研究了形态计量学和分子系统学的斑马贻贝（Dreissena polymorpha）和深水和epilimnetic形式的斑驴贻贝（Dreissena bugensis）从伊利湖和安大略。在试图解决的深层形式的斑驴贻贝的分类地位，我们测序的细胞色素氧化酶亚基I线粒体基因的两种形式的斑驴贻贝的710个碱基对的片段。没有发现核苷酸差异，支持了斑驴贻贝的深底型是D. bugensis，而不是一个单独的物种。与此相反，第二和第三主成分得分从分析的形态变量壳长，壳宽，壳高，壳...
The discovery of a morphologically distinct dreissenid mussel in the profundal zone of Lake Erie suggests the presence of either a third dreissenid mussel species in the Great Lakes or a previously unknown morphological phenotype of an existing dreissenid species. We examined the morphometrics and molecular systematics of the zebra mussel (Dreissena polymorpha) and the profundal and epilimnetic forms of the quagga mussel (Dreissena bugensis) from Lakes Erie and Ontario. In an attempt to resolve the taxonomic status of the profundal form of the quagga mussel, we sequenced a 710 base pair fragment of the cytochrome oxidase subunit I mitochondrial gene of the two forms of the quagga mussel. No nucleotide differences were found, supporting the hypothesis that the profundal form of the quagga mussel is a phenotype of D. bugensis, not a separate species. In contrast, the second and third principal component scores from an analysis of the morphological variables shell length, shell width, shell height, and shell...
