Molecular Survey ofCodiumSpecies Diversity in Southern Madagascar

We present a molecular survey of the species in the green algal genus Codium that were collected as part of the Atimo Vatae expedition to southern Madagascar. Based on clustering analysis of partial tufA and rbcL sequences, we recognize 11–12 species-level clusters in this area. Through a combination of morphological identifications and DNA comparisons, these clusters are identified as C. mozambiquense, C. spongiosum, C. lucasii subsp. capense,...
