Summary: | There is currently conflict in the literature on the taxonomic status of the reportedly cosmopolitan species Neosiphonia harveyi, a common red alga along the coast of Atlantic Canada and New England, USA. Neosiphonia harveyi sensu lato was assessed using three molecular markers: COI-5P, ITS and rbcL. All three markers clearly delimited three genetic species groups within N. harveyi sensu lato in this region, which we identified as N. harveyi, N. japonica and Polysiphonia akkeshiensis (here resurrected from synonymy with N. japonica). Although Neosiphonia harveyi is considered by some authors to be introduced to the Atlantic from the western Pacific, it was only confirmed from the North Atlantic suggesting it is native to this area. In contrast, Neosiphonia japonica was collected from only two sites in Rhode Island, USA, as well as from its reported native range in Asia (South Korea), which when combined with data in GenBank indicates that this species was introduced to the Northwest Atlantic. The GenBank ... : ITS sequence alignmentAn alignment of ITS sequences that were used to create a neighbor-joining tree for Figure 1COI-5P sequence alignmentAn alignment of COI-5P sequences that were used to create a neighbor-joining tree for Figure 1rbcL sequence alignmentAn alignment of rbcL sequences that were used to create a neighbor-joining tree for Figure 3Figure 3 rbcL treeA neighbor-joining tree generated from rbcL sequence dataFigure 1 COI-5P treeA neighbor-joining tree generated from COI-5P sequence dataFigure 1 ITS treeA neighbor-joining tree generated from ITS sequence data ... |
