Abstract

Author(s): Stanely, Louis; Murray, Christopher M; Murray, Jon J; Crother, Brian I | Abstract: Islands represent interesting biogeographic features often defined by unique and dynamic geological and biological components. Such systems serve as examples of the basic fundamental units of biogeographical analyses: areas of endemism. The island of Jamaica is recognized as possessing a unique biota with a large number of herpetofauna species persisting only within the island. Further, Jamaica exhibits a dynamic geologic history characterized by an easterly migration and repeated inundation, resulting in a contemporary biota formed through dispersal. Here, we infer areas of endemism across Jamaica based on 57 amphibian and reptile distributions using Parsimony Analysis and Endemism (PAE). We recover 19 areas of endemism concentrated in two regions: The Blue Mountains region diagnosed by 8 taxa and the west/central limestone plateau region including Cockpit Country and the western Dolphin Head region, diagnosed by 9 taxa. Further discussion on the utility of ambiguous syntaxa in diagnosing extinction, dispersal and ecological patterns as they pertain to biogeographic units is provided.n

牙买加特有区域:基于两栖类和爬行类分布的地方性简约分析推论

作者:Stanely, Louis;默里，克里斯托弗·M;默里，乔恩·J;摘要/ Abstract摘要:岛屿具有独特的、动态的地质和生物特征。这些系统作为生物地理分析的基本单位的例子:特有区。牙买加岛被认为拥有独特的生物群，大量的爬行动物物种只存在于该岛内。此外，牙买加呈现出一个动态的地质历史，其特征是向东迁移和反复淹没，导致当代生物群通过分散形成。在这里，我们根据57种两栖动物和爬行动物的分布，使用简约分析和地方性分析(PAE)来推断牙买加的地方性区域。我们发现了19个地区的特有物种，主要集中在蓝山地区和西/中部石灰岩高原地区(包括座舱区和西海豚头区)。进一步讨论了模糊句法在诊断生物地理单位的灭绝、扩散和生态模式方面的应用
