| Summary: | Large aggregations of sylasterid corals have been identified throughout the offshore waters of the Antarctic, Sub-Antarctic and South America. These biodiverse regions are interspersed by deep trenches, channels, sedimentary plains and isolated rocky habitat, which may facilitate or inhibit dispersal over evolutionary and ecological time scales. Deep-sea sampling has increased exponentially, across these benthic habitats, due to collaborative projects such as the Census of Antarctic Marine Life (CAML). Consequently, it is now possible to attempt to combine genetic and taxonomic expertise, explore evolutionary relationships and assess this data in relation to environmental change ‚Äö- both past and future. The biogeographic distribution of stylasterid corals is representative of population isolation, based on the discovery of dissimilar species aggregations throughout sampled regions. To further investigate this biogeographic pattern, I sampled all 33 of the known stylasterid species documented from the ... |
