“…This marker is highly variable in red algae and has been successfully shown to contain phylogeographic information in marine macroalgal studies (e.g., Kim et al. , Dumilag and Monotilla ). Levels of intrapopulation genetic diversity and pairwise interpopulation genetic differentiation parameters were quantified using DnaSP v.5.10.01 (Librado and Rozas ).…”

Populations of the marine benthic red macroalgae Hypnea musciformis and Hypnea pseudomusciformis along the Atlantic and Pacific Oceans were tested for phylogeographic structure using the DNA barcode COI‐5P combined with rbcL for the construction of the phylogenetic tree. Strong patterns of genetic structure were detected across 210 COI‐5P DNA sequences, and 37 COI‐5P haplotypes were found, using multiple statistical approaches. Hypnea musciformis was found in the Northeast and Northwest Atlantic, the Mediterrean Sea, Namibia, and along the Pacific coast of Mexico. Two new putative species were detected, Hypnea sp. 1 in the Caribbean Sea and Hypnea sp. 2 in the Dominican Republic. Three distinct marine phylogeographic provinces were recognized in the Southern Hemisphere for H. pseudomusciformis: Uruguay, South‐Southeast Brazil, and Northeast Brazil. The degree of genetic isolation and distinctness among these provinces varied considerably. The Uruguay province was the most genetically distinct, as characterized by four unique haplotypes not shared with any of the Brazilian populations. Statistically significant results support both, isolation by distance and isolation by environment hypotheses, explaining the formation and mantainance of phylogeographic structuring along the Uruguay‐Brazil coast. Geographic, taxonomic and molecular marker concordances were found between our H. pseudomusciformis results and published studies. Furthermore, our data indicate that the Hawaiian introduced populations of H. musciformis contain Hypnea sp. 1 haplotypes, the current known distribution of which is restricted to the Caribbean.

“…Our results are consistent with previous reports (Patwary et al 1993) that G. vagum isolates have sufficient genetic diversity for conducting a heterosis experiment using random amplified polymorphic DNA methods. In contrast, genetic diversities were relatively low (Hd, 0.711) in G. elegans (Kim et al 2012) and (Hd,0.757) in Gracilaria vermiculophylla (Ohmi) Papenfuss (Kim et al 2010). The latter two species are dioecious, species, a trait which may account for increasing heterozygosity and variability.…”

“…Mitochondrial-encoded cox1 is a fast-evolving gene that has recently proved valuable for barcoding red algal species (Saunders and Moore 2013) and for revealing the biogeographic structure of populations (Kim et al 2010(Kim et al , 2012. Cytochrome b (cob), one of the 12 markers undergoing tests to determine its utility for phylogenetic (Hughey et al 1996, Mineur et al 2012.…”

The number of species of non-native and invasive marine algae is growing, with concomitant public concern about native ecosystems and coastlines. Gelidium vagum, recently introduced from northeast Asia to Europe and North America, commonly occurs from the intertidal to subtidal zones in Korea, China, and Japan. To investigate the level of genetic diversity of native populations, we analyzed mitochondrial cox1 and cob from 108 specimens of G. vagum from Korea, China, eastern Russia, including from the Netherlands and USA. The haplotype network of individual and cox1 + cob datasets revealed no genetic structure in local populations, suggesting genetic flow between Korean populations. Our results corroborate a typical pattern of genetic diversity for introduced species, with low levels in introduced populations and high levels in native populations. All haplotypes were shared between the Netherlands and USA, but not between Korea and the Netherlands / USA except cox1. Additional sampling will identify donor populations in native northeast Asian waters. This is the first report of the utility of the mitochondrial coding cob sequences in red algae.

“…The different current directions restricting the water motion out of the Gulf may explain why samples from the Gulf of Thailand lineage are not found in the Andaman Sea and other areas. The effect of ocean currents on species and genotype distribution can be seen in other macroalgae, for example, Gelidium elegans (Kim et al, 2012), Carpophyllum maschalocarpum (Buchanan & Zuccarello, 2012), Sargassum polycystum (Chan et al, 2013) and Sargassum aquifolium (Chan et al, 2014). The currents in the Gulf of Thailand may affect genotype distribution of many organisms found on either side of the Thai-Malay Peninsula.…”

The Indo-Pacific Ocean is a biodiversity hotspot for marine organisms. In this area, most of the research has focused on marine animals, such as reef fish, molluscs and other associated coral fauna, but very little has been done on macroalgae. The Thai-Malay Peninsula is an important north-south barrier in this area, which faces two different oceans -the Indian Ocean and the Pacific Ocean. This study aims to investigate genetic distribution patterns of Padina boryana Thivy around the Thai-Malay Peninsula, where it is common. Three DNA marker regions, the mitochondrion-encoded cytochrome c oxidase subunit 3 gene (cox3); the plastid rbcL, and the nuclear internal transcribed spacer 2 (ITS2) were used to evaluate genetic diversity and the relationships within and between populations. Samples were collected from both the Andaman Sea and Gulf of Thailand sides of the peninsula. Parsimony networks and maximum likelihood and Bayesian analyses showed clearly that there are two separated P. boryana lineages, one restricted to the Gulf of Thailand and the other to the Andaman Sea and other areas of the Indo-Pacific. The effect of different ocean currents along the Andaman Sea and Gulf of Thailand may have shaped these populations of P. boryana. This phylogeographic separation, based on persistent currents in the area, may affect other marine organisms along the Thai peninsula.
