Abstract

There are many cases of animals reported in localities away from natural areas of distribution for the species. With respect to native freshwater turtles of Argentina and bordering countries, several populations (and single specimens) were reported for areas that cast doubts about their origin, due to not only the long distance from other known localities but also the geographical barriers that are in between. The present work provides a review of localities of the native turtle species Hydromedusa tectifera, Phrynops hilarii, Acanthochelys pallidipectoris, A. spixii and Trachemys dorbigni in Argentina, Bolivia, Brasil, Paraguay and Uruguay, and adds new records for some of these species for Argentina. We also employ an analysis to recognise core and extralimital populations, and a methodology based on five criteria that must be taken into account to elucidate if one extralimital turtle record is the result of anthropogenic action or a case of natural occurrence. Finally, we discuss about the origin of extralimital reports of turtles of the mentioned species.
南美洲南部螯龟和赤蠵龟分布综述,重点介绍了阿根廷的物种外种群和新记录
据报道,在远离该物种自然分布区域的地方有许多动物病例。关于阿根廷及其邻国的本地淡水龟,在一些地区报告了几个种群(和单个标本),这些地区对它们的起源产生了怀疑,这不仅是因为与其他已知地点的距离很远,而且是因为两者之间存在地理障碍。本文综述了阿根廷、玻利维亚、巴西、巴拉圭和乌拉圭等国龟种Hydromedusa tectifera、Phrynops hilarii、Acanthochelys pallidipectoris、a. spixii和Trachemys dorbigni的分布情况,并增加了阿根廷部分龟种的新记录。我们还采用了一种分析方法来识别核心种群和生态外种群,并采用了一种基于五个标准的方法来阐明一个生态外海龟记录是人为活动的结果还是自然发生的情况。最后,我们讨论了上述物种龟的域外报道的来源。
