Abstract
Molecular and breeding studies on two pan-tropical marine red algae reveal vastly different levels of genetic variation and reproductive isolation. Sequenced DNA regions from the nuclear, mitochondrial and plastid genomes (partial LSU rRNA, cox2-3 spacer, RuBisCo spacer, respectively) revealed high genetic variation among individuals of Spyridia filamentosa. An rbcL analysis shows that Spyridia is a monophyletic genus distinct from other Ceramiaceae sampled, suggesting that the Ceramiaceae could be paraphyletic. There is complete congruence between all data sets of S. filamentosa, showing a well-supported phylogeographic pattern with samples from the Pacific distinct from Atlantic and Indian..
