Tracking dispersal routes:phylogeography of the arctic antarctic disjunct seaweed acrosiphonia-arcta (chlorophyta)
Phylogenetic relationships in the Arctic-Antarctic disjunct seaweed species Acrosiphonia arcta (Dillwyn) J. G. Agardh (Acrosiphoniales, Chlorophyta) were examined using restriction fragment-length polymorphism analysis of the fast-evolving nuclear ribosomal intergenic spacer (IGS) region and random...
