南部非洲海洋区位于大西洋和印度洋-太平洋生物群落之间的过渡区。它的生物多样性特别丰富，包括来自两个主要海洋区域的动物和植物成分，以及大量的地方性物种。在这一领域内，地理位置非常接近的生物群差异极大，许多物种分布在该区域两个或两个以上的海洋地理省，被划分为进化单位，往往只能根据遗传数据加以区分。在这篇评论中，我们描述了南部非洲的海洋生物地理学的状态，也就是说，在物种水平上的进化关系的研究，或密切相关的物种之间，在该地区的海洋环境。我们特别关注沿海地区的地理，最近取得了很大的进展，在确定地理断裂，并解释他们是如何起源和维持。我们还着重指出应在不久的将来解决的许多不足之处。其中包括：关于具有重要商业价值的生物体，特别是近海物种的数据有限;关于近岸地区的海洋学数据缺乏;缺乏基于多位点数据的研究;以及研究物种形成中多样化选择的作用仅限于生理学方法，而没有考虑遗传学。越来越明显的是，南部非洲海洋领域是世界上最有意义的环境之一，可以在其中研究不仅影响区域而且影响全球海洋生物多样性格局的演变过程。
The southern African marine realm is located at the transition zone between the Atlantic and Indo-Pacific biomes. Its biodiversity is particularly rich and comprises faunal and floral elements from the two major oceanic regions, as well as a large number of endemics. Within this realm, strikingly different biota occur in close geographic proximity to each other, and many of the species with distributions spanning two or more of the region’s marine biogeographic provinces are divided into evolutionary units that can often only be distinguished on the basis of genetic data. In this review, we describe the state of marine phylogeography in southern Africa, that is, the study of evolutionary relationships at the species level, or amongst closely related species, in relation to the region’s marine environment. We focus particularly on coastal phylogeography, where much progress has recently been made in identifying phylogeographic breaks and explaining how they originated and are maintained. We also highlight numerous shortcomings that should be addressed in the near future. These include: the limited data available for commercially important organisms, particularly offshore species; the paucity of oceanographic data for nearshore areas; a dearth of studies based on multilocus data; and the fact that studying the role of diversifying selection in speciation has been limited to physiological approaches to the exclusion of genetics. It is becoming apparent that the southern African marine realm is one of the world’s most interesting environments in which to study the evolutionary processes that shape not only regional, but also global patterns of marine biodiversity.
