欧洲池龟（Emys orbicularis）是非洲动物群中的一个新北元素，被认为是从伊比利亚半岛入侵北非的。所有的北非种群目前都被鉴定为E亚种。O. [咒语]然而，在北非用于线粒体和微卫星DNA分析的几乎全范围的采样提供了证据，表明只有摩洛哥种群属于这一分类群，而东部阿尔及利亚和突尼斯池龟代表一个未描述的独特亚种。这两个类群与E. O.原产于沿着地中海沿岸的北方西班牙，通过法国南部到意大利西部和南部。这组是姐妹的一个分支，包括几个线粒体谱系和亚种的E。orbiculentum从中欧和东欧加上亚洲，和连续的姐妹篇是E。O.希腊和E. Trinacris结果表明，E.据估计，圆龟在北非的存在时间比在伊比利亚半岛的存在时间更长，在来自未知欧洲来源地区的池龟最初入侵北非之后，北非出现了一个多样化阶段，随后非洲血统之一再次入侵欧洲。在北非的池龟的分化平行于一般的两栖动物和爬行动物，在西部和东部马格里布深刻分歧的谱系地理范式。承认他们的遗传相似性，我们建议synchronizing以前公认的伊比利亚subspeciesE。O. fritzjuergenobstiwithE. O.严格意义上的客观主义。严重危及E的摩洛哥人口。O.线粒体单倍型和微卫星标记是两个不同的管理单位。阿尔及利亚东部池龟的保护状况尚不清楚，而突尼斯的种群则濒临灭绝。考虑到阿尔及利亚和突尼斯池龟是一种地方性物种，应调查其在整个历史范围内的情况，为保护措施奠定基础。
The European pond turtle (Emys orbicularis) is a Nearctic element in the African fauna and thought to have invaded North Africa from the Iberian Peninsula. All North African populations are currently identified with the subspeciesE. o. occidentalis. However, a nearly range-wide sampling in North Africa used for analyses of mitochondrial and microsatellite DNA provides evidence that only Moroccan populations belong to this taxon, while eastern Algerian and Tunisian pond turtles represent an undescribed distinct subspecies. These two taxa are most closely related toE. o. galloitalicawith a native distribution along the Mediterranean coast of northern Spain through southern France to western and southern Italy. This group is sister to a clade comprising several mitochondrial lineages and subspecies ofE. orbicularisfrom Central and Eastern Europe plus Asia, and the successive sisters areE. o. hellenicaandE. trinacris. Our results suggest thatE. orbicularishas been present in North Africa longer than on the Iberian Peninsula and that after an initial invasion of North Africa by pond turtles from an unknown European source region, there was a phase of diversification in North Africa, followed by a later re-invasion of Europe by one of the African lineages. The differentiation of pond turtles in North Africa parallels a general phylogeographic paradigm in amphibians and reptiles, with deeply divergent lineages in the western and eastern Maghreb. Acknowledging their genetic similarity, we propose to synonymize the previously recognized Iberian subspeciesE. o. fritzjuergenobstiwithE. o. occidentalissensu stricto. The seriously imperiled Moroccan populations ofE. o. occidentalisrepresent two Management Units different in mitochondrial haplotypes and microsatellite markers. The conservation status of eastern Algerian pond turtles is unclear, while Tunisian populations are endangered. Considering that Algerian and Tunisian pond turtles represent an endemic taxon, their situation throughout the historical range should be surveyed to establish a basis for conservation measures.
