“…However, the mechanisms on how such drivers of genetic isolation operate are quite different. While the Doce river has been considered an extant putative hard or semipermeable (= soft) barrier to gene flow, the Vitoria-Trindade seamount chain is considered an old intermittent barrier driving genetic isolation during periods of glacial maxima (Pinheiro et al 2017, Menezes et al 2020. Unfortunately, our results were not able to estimate which of them exerted the largest historical influence driving C. sinuosa phylogeographic structure.…”

“…This region is the genetic transition zone between C. sinuosa south and north phylogroups. Southern Bahia is a biodiversity hotspot for both terrestrial and marine species, acting as a historical glacial refugium during the Pleistocene (Carnaval et al 2009, Lazoski et al 2011, Hurtado et al 2016, Paiva et al 2019, Menezes et al 2020.

Colpomenia sinuosa is a cosmopolitan brown macroalgal species complex and hence a great candidate for evolutionary studies in the marine environment. Since 2009, three major C. sinuosa phylogenetic lineages, subdivided into eight subgroups, have been identified based on cox3 DNA sequences from worldwide collections. However, worldwide sampling remains limited and spotty. To date molecular data from Brazilian C. sinuosa populations have been limited to 10 specimens collected in a single locality. Nonetheless, C. sinuosa populations occur along the entire ~8,000 km Brazilian coast. Consequently, knowledge on population genetic diversity and spatial genetic structuring along most of the Brazilian coastline is nonexistent. To fulfill this gap in knowledge, we performed a phylogeographic analysis of C. sinuosa populations in Brazil. The highly variable cox3 marker was sequenced for 148 individuals collected in 12 localities in Brazil. Results identified two genetically distinct population groups (north vs. south) separated at 20.5°S latitude. Genetic diversity in northern populations is 14.6 and 15.5 times greater than southern populations in terms of haplotype and nucleotide diversity, respectively. Among northern populations, the Bahia state holds the largest genetic diversity. The southern populations had lower genetic diversity and no internal genetic sub-structure suggesting past bottlenecks followed by recent colonization from northern haplotypes. Our results do not indicate recent introductions of foreign haplotypes in Brazil and reinforce the crucial importance of historical and extant allopatric, parapatric, and sympatric processes driving marine macroalgal evolution in the Southwestern Atlantic Ocean.
