Linking phenotypic variation to patterns of genetic isolation along a speciation continuum.

ABSTRACT: Investigating taxa at varying stages of divergence can shed light on the evolutionary forces that lead to reproductive isolation and eventual speciation. The forces promoting isolation vary in space and time, which makes it difficult to reconstruct the trajectory that resulted in the divergence observed among species today. The red macroalgal genus Plocamium is known worldwide for its cryptic genetic and chemical diversity. Previous work on the genus Plocamium in Antarctica observed two haplotypes along the western Antarctic Peninsula that have been treated as the same species. Using 10 microsatellite loci, we observed that these two haplotypes correspond to two highly divergent, co-occurring genetic entities in Antarctic Plocamium, which are located within close vicinity of each other at
