扩散和vicariance之间的区别进行了讨论，并显示它们如何与地质历史。假设理论的构造起源和历史的大安的列斯群岛进行审查，以及可能的气候事件，将影响地理。许多动物学的例子，提出了争论扩散和vicariance的观点。建议现代苔藓植物群的大安的列斯群岛是最好的解释，主要是扩散事件。后替代事件，如更新世的气候变化，将使绝大多数苔藓从岛屿上消失，即使在那些幸存的类群中，分散在同一类群中也会掩盖它们的起源。据推测，伊斯帕尼奥拉岛高海拔地区的许多北美元素是更新世入侵的结果。安第斯成分被认为是相对较新的分散衍生的分类群，由于生态相容的栖息地而成功地殖民了安的列斯群岛。
The distinctions between dispersal and vicariance are discussed and shown how they relate to geological history. Postulated theories on the tectonic origins and history of the Greater Antilles are reviewed, as well as possible climatic events that would affect biogeography. Numerous zoological examples are presented to argue both dispersalist and vicariance viewpoints. It is proposed that the modern moss flora of the Greater Antilles is best explained primarily by dispersal events. Post-vicariant events, such as Pleistocene climate changes, would have extirpated the vast majority of mosses from the islands and even among those taxa that survived, disperal by the same taxa would have obscured their origins. It is assumed that many of the North American elements in the high elevations of Hispaniola are a result of invasions during the Pleistocene. The Andean elements are considered relatively recent dispersally derived taxa that have successfully colonized the Antilles because of ecologically compatible habitats.
