“…While these patterns are clear in some species (e.g., Barber et al 2002, DeBoer et al 2008, 2014b, they can be less clear in others. For example, Vogler et al (2008) demonstrated that the crown of thorns sea star, Acanthaster planci (Linnaeus, 1758), is likely a species complex and multiple "species" and haplogroups are distributed across the Coral Triangle. However, it is unclear whether overlapping distributions in the Coral Triangle result from secondary contact (with potential hybridization) following allopatric speciation, or whether speciation resulted from natural selection in sympatry.…”

ABSTRACT.-In March 2012, the authors met at the National Evolutionary Synthesis Center (NESCent) in Durham, North Carolina, USA, to discuss approaches and cooperative ventures in Indo-Pacific phylogeography. The group emerged with a series of findings: (1) Marine population structure is complex, but single locus mtDNA studies continue to provide powerful first assessment of phylogeographic patterns. (2) These patterns gain greater significance/power when resolved in a diversity of taxa. New analytical tools are emerging to address these analyses with multi-taxon approaches. (3) Genome-wide analyses are warranted if selection is indicated by surveys of standard markers. Such indicators can include discordance between genetic loci, or between genetic loci and morphology. Phylogeographic information provides a valuable context for studies of selection and adaptation. (4) Phylogeographic inferences are greatly enhanced by an understanding of the biology and ecology of study organisms. (5) Thorough, range-wide sampling of taxa is the foundation for robust phylogeographic inference. (6) Congruent geographic and taxonomic sampling by the IndoPacific community of scientists would facilitate better comparative analyses. The group concluded that at this stage of technology and software development, judicious rather than wholesale application of genomics appears to be the most robust course for marine phylogeographic studies. Therefore, our group intends to affirm the value of traditional ("unplugged") approaches, such as those based on mtDNA sequencing and microsatellites, along with essential field studies, in an era with increasing emphasis on genomic approaches.

Abstract:The global zoogeographic distribution of the most widespread peracarid species occurring in three or more ocean basins below 2000 m is analysed. Basing on the published data we investigated 45 peracarid species, which have a most widespread distribution and most likely are cosmopolitan. Thirty−three species have a wide distribution in the Northern Hemisphere. Most species occur in the North Atlantic, however, 16 of these species occur also in the North Pacific, a more limited number of species occurs in the South Atlantic or South Pacific The Southern Ocean displays some special zoogeographic features and 22 widespread species occur there below 2000 m, including highly eurybathic ones. In total, 11 of the analysed species occur in all oceans. Eucopia australis (Lophogastrida), Munneury− cope murrayi (Isopoda) and Eurythenes gryllus (Amphipoda) are the species with the wid− est distributions. Other peracarids occurring in all oceans are: the isopods Paramunnopsis oceanica and Eurycope sarsi, the mysid Caesaromysis hispida the lophogastrid Eucopia unguiculata, the amphipod Mesopleustes abyssorum and the tanaids Exspina typica, Para− narthura insignis and Pseudotanais nordenskioldi. No cumacean species has been reported with an ocean−wide distribution but Campylaspis glabra occurs in the Atlantic, Indian and Pacific oceans. Among plenty of rare species in each order there are only few species with wide distribution records. There is evidence from molecular genetic studies that some of the widespread peracarids represent several cryptic species, however, some, e.g. Eucopia aus− tralis, seem to be truly cosmopolitan species. Geography of sampling is biasing our view of biogeography. The history and quality of taxonomic work as well as the reliability of geo− graphic records (quality control of large databases) limits our investigations of widespread or cosmopolitan species as much as the limited knowledge of variation within most species causes difficulties in defining morpho−species with certainty.

“…Molecular work on the starfish A. planci, including specimens from Panama, revealed that it is not in fact a single species, but a pan-Indo-Pacific species complex consisting of four deeply diverged clades (Pacific, Red Sea, Northern Indian Ocean, and Southern Indian Ocean) (Vogler et al 2008). These clades reportedly diverged between 1.95 and 3.65 mya (Pliocene to early Pleistocene) and have genetic distances (8.8-10.6 %) equivalent to the distances between other sibling species of starfish (Waters et al 2004).…”

Vogler et al (2008) propose that this speciation process was driven by sea level changes (Pillans et al 1998) that isolated populations.…”
