The Azores, Madeira, Selvagens, Canary Islands and Cabo Verde are commonly united under the term "Macaronesia". This study investigates the coherency and validity of Macaronesia as a biogeographic unit using six marine groups with very different dispersal abilities: coastal fishes, echinoderms, gastropod molluscs, brachyuran decapod crustaceans, polychaete annelids, and macroalgae. We found no support for the current concept of Macaronesia as a coherent marine biogeographic unit. All marine groups studied suggest the exclusion of Cabo Verde from the remaining Macaronesian archipelagos and thus, Cabo Verde should be given the status of a biogeographic subprovince within the West African Transition province. We propose to redefine the Lusitanian biogeographical province, in which we include four ecoregions: the South European Atlantic Shelf, the Saharan Upwelling, the Azores, and a new ecoregion herein named Webbnesia, which comprises the archipelagos of Madeira, Selvagens and the Canary Islands.
亚速尔群岛、马德拉群岛、塞尔瓦根群岛、加那利群岛和佛得角通常被归为“马卡罗内西亚”这一术语。本研究使用六种具有不同扩散能力的海洋生物群，来探究马卡罗内西亚作为一个生物地理单元的一致性和有效性：沿海鱼类、棘皮动物、腹足纲软体动物、短尾十足目甲壳类动物、多毛环节动物和大型藻类。我们没有发现支持马卡罗内西亚作为一个连贯的海洋生物地理单元的当前概念的证据。所有研究的海洋生物群都表明，佛得角应排除在其余的马卡罗内西亚群岛之外，因此，佛得角应该被赋予西非过渡省的生物地理分区地位。我们建议重新定义卢西塔尼亚生物地理省，其中包括四个生态区：南欧大西洋大陆架、撒哈拉上升流、亚速尔群岛，以及一个新的生态区，在此命名为 Webbnesia，包括马德拉群岛、塞尔瓦根群岛和加那利群岛。
