Allozyme variation was examined in 175 individuals representing 13 putative species of Sargassum (Sargassum aquifolium, S. carpophyllum, S. decurrens, S. fissifolium, S. ligulatum, S. linearifolium, S. oligocystum, S. opacum, S. parvifolium, S. polycystum, S. siliquosum, S. spinifex, S. swartzii) and 34 populations from the Great Barrier Reef, Australia.

Allozyme variability was examined (five polymorphic loci, 12 alleles total), between morphological species and those between different geographical populations of the same taxon.

Sargassum decurrens, S. oligocystum, S. parvifolium and S. swartzii + S. aquifolium, were sampled in sympatry. S. carpophyllum and S. polycystum are conspecific. Single populations of 3 different species were thought to be possible misassignments (S. opacum = S. polycystum; S. aquifolium = S. swartzii and S. linearifolium = S. fissifolium), but may be morphological variants of the species with which they clustered. Finally, S. oligocystum (subgenus Eusargassum) clustered with S. decurrens, (subgenus Phyllotrichia) suggesting a revision of subgeneric boundaries in the genus Sargassum is required.

Allele frequencies at five loci (GPI, SOD-1, ACO-1, ME-1, PGM-1) were examined.

Calculation of gene frequencies and population genetic statistics were carried out using BIOSYS-1 package. Genetic relationships were represented using Nei's genetic distance and Roger's genetic distance, and clustered using the UPGMA method.
