使用 AFLP 证据，对欧洲海岸广泛分布的五种开花植物（Cakile maritima、Eryngium maritimum、Salsola kali、Halimione portulacoides、Cithmum maritimum）的系统发育地理学在其整个欧洲范围内进行了调查。既发现了相似之处，也发现了不同之处。所有物种都包含一个独特的黑海/爱琴海簇，并且除 E. maritimum 之外的所有物种都包含一个独特的亚得里亚海簇或一组遗传上非常相似的簇。除 Cr maritimum 之外的所有物种都包含明显与地中海物质分开的大西洋/北海/波罗的海簇。在加州。 maritima 是一个独特的波罗的海亚群被发现。在地中海西部，可以识别两个物种组。然而，在 S. kali 和 E. maritimum 中，来自该地区的材料仅落入一个簇或一组遗传上非常相似的簇，而在 Ca 中，它落入两个簇或一组与大西洋或地中海中部更相似的簇。 maritima、H. portulacoides 和 Cr。玛丽蒂姆。结合历史和现存的非生物和生物因素来讨论所发现模式的相似性和不同点。因此，东地中海地区所有物种的分布范围均未受到第四纪温度变化的影响，导致这里的系统发育地理学一致。不同的黑海/爱琴海和亚得里亚海集群或集群群的存在是海流将这些区域彼此隔离的结果。在西地中海盆地，对寒冷较敏感的物种（H. portulacoides、Cr: maritimum）必须从北部海岸撤退，但对寒冷不太敏感的物种（S. kali、E. maritimum）则不然。这些地区的系统发育地理模式暗示着从两个不同方向的重新殖民。直布罗陀差距的存在可以用现存海流来解释。将发现的系统发育地理模式与在海洋或陆地生物中观察到的系统发育地理模式进行比较得出的结论是，海洋传播对于这些沿海植物至关重要。
The phylogeography of five flowering plant species (Cakile maritima, Eryngium maritimum, Salsola kali, Halimione portulacoides, Crithmum maritimum) widespread along the European coasts was investigated across their entire European range using AFLP evidence. Both similarities and dissimilarities were found. All species contain a distinct Black Sea/Aegean Sea cluster, and all except E. maritimum contain a distinct Adriatic Sea cluster or group of genetically very similar clusters. All species except Cr maritimum contain a distinct Atlantic Ocean/North Sea/Baltic Sea cluster clearly separate from the Mediterranean material. In Ca. maritima a distinct Baltic Sea subcluster was found. In the western Mediterranean, two species groups can be recognized. Whereas in S. kali and E. maritimum material from this area falls into only one cluster or a group of genetically very similar clusters, it falls into two clusters or groups of clusters of either more Atlantic or more central Mediterranean similarity in Ca. maritima, H. portulacoides and Cr. maritimum. Similarities and dissimilarities in patterns found are discussed in terms of a combination of historical and extant abiotic and biotic factors. Thus, the distribution range of all species in the eastern Mediterranean area was not affected by Quaternary temperature changes, resulting in phylogeographic congruency here. The existence of distinct Black Sea/Aegean Sea and Adriatic Sea clusters or groups of clusters is the result of sea currents isolating these regions from each other. In the western Mediterranean basin the more cold-sensitive species (H. portulacoides, Cr: maritimum) but not the less cold-sensitive species (S. kali, E. maritimum) had to retreat from northern coasts. Re-colonization of these areas from two different directions is implied by their phylogeographic pattern. The existence of a distinct Gibraltar gap is explained in terms of extant sea currents. Comparison of phylogeographic patterns found with those observed in either marine or terrestrial organisms leads to the conclusion that marine dispersal is of overriding importance in these coastal plants.
