Origin, diversification, and historical biogeography of the giant kelps genus Macrocystis: Evidences from Bayesian phylogenetic analysis

We evaluate the genetic divergence between the two morphs of the genus Macrocystis found in the Chilean coast (pyrifera and integrifolia), and the historical relationships with the other morphs of the genus using the ITS-2 DNA region sequences. The analyses sustain that the morphotypes, and its dist...
