Multiple locus phylogeography to evaluate the diversity of the Cold Water Soft Coral Alcyonium spp. (Anthozoa, Octocorallia: Alcyonacea) between South America and West Antarctic Peninsula ...
The Antarctic marine environment has a unique geologic and climatic history that has contributed to the evolution of a diverse range of species. With the environment undergoing warming trends, it is critical to understand the history of Antarctic species to anticipate the effect of environmental cha...
