Cladistic biogeography is an evolutionary biogeographic approach that infers area relationships by comparing area cladograms derived from different phylogenetic hypotheses. The South American freshwater ichthyofauna is enriched by an extraordinary number of marine-derived lineages, presenting its own phylogenetic and biogeographic patterns. Here, we performed a Brooks Parsimony Analysis (BPA) with the latest phylogenetic proposals for Anablepidae to compare hypotheses about the historical relationships among areas previously recognized based on fish species from the Neotropical region. We found that the area relationships for Anablepidae are in accordance with the pattern evidenced for other marine-derived lineages. The general area cladogram obtained shows a three-area relationship pattern, where freshwater is the sister group of Pacific + Atlantic marine areas. Within the freshwater clade, Southern Brazil + Uruguay River basin and Northwestern Argentina + Midwestern Argentina form two clades. Vicariance, dispersal, and extinction events related to Miocene and Quaternary marine transgressions and ancient connections between the Iguaçu and Upper Uruguay River basins supported the historical relationships among areas proposed here. Our results may be applied to patterns shown by other marine-derived lineages, as well as other freshwater organisms not necessarily having marine origins.

淡水鱼科 Anablepidae (Teleostei: Cyprinodontiformes) 的进化生物地理学,一种源自海洋的新热带谱系

分支生物地理学是一种进化生物地理学方法,它通过比较来自不同系统发育假设的区域分支图来推断区域关系。南美淡水鱼群丰富了大量源自海洋的谱系,呈现出自己的系统发育和生物地理模式。在这里,我们使用 Anablepidae 的最新系统发育建议进行了布鲁克斯简约分析 (BPA),以比较先前根据新热带地区鱼类物种识别出的区域之间的历史关系的假设。我们发现 Anablepidae 的面积关系与其他海洋衍生谱系所证明的模式一致。获得的一般区域分支图显示了一个三区域关系模式,其中淡水是太平洋+大西洋海域的姊妹组。在淡水进化枝内,巴西南部+乌拉圭河流域和阿根廷西北部+阿根廷中西部形成两个进化枝。与中新世和第四纪海侵以及伊瓜苏和乌拉圭上游河流域之间的古老联系相关的替代、扩散和灭绝事件支持这里提出的地区之间的历史关系。我们的结果可能适用于其他海洋衍生谱系以及其他不一定具有海洋起源的淡水生物所显示的模式。与中新世和第四纪海侵相关的灭绝事件以及伊瓜苏和乌拉圭上游河流域之间的古老联系支持了这里提出的地区之间的历史关系。我们的结果可能适用于其他海洋衍生谱系以及其他不一定具有海洋起源的淡水生物所显示的模式。与中新世和第四纪海侵相关的灭绝事件以及伊瓜苏和乌拉圭上游河流域之间的古老联系支持了这里提出的地区之间的历史关系。我们的结果可能适用于其他海洋衍生谱系以及其他不一定具有海洋起源的淡水生物所显示的模式。
