Explanations of distributions of terrestrial organisms have included over-water disperal, land dispersal and vicariance, with two main explanations being the vicariance model of Rosen (1975) and the GAARlandia hypothesis of Iturralde-Vinent and MacPhee (1999). The land snail family Annulariidae, endemic to the Caribbean, has shown similar patterns to other organisms in the region and is used to help evaluate the relative role of over water dispersal, land dispersal and vicariance. A molecular phylogeny using regions of the nuclear ribosomal 28S, mitochondrial ribosomal 16S, and the mitochondrial protein coding gene COI was reconstructed and used to assess patterns of biogeography. Ancestral ranges were reconstructed using the program RASP with the BBM and S-diva algorithms. These analyses suggest a proto-Antillean origin of the fauna with subsequent over-water dispersals, relying heavily on land or over-water dispersals as a mechanism. Little evidence was found in support of the GAARlandia hypothesis, yet it cannot be completely removed as a potential explanation. Herein, we describe the historical biogeographic patterns of the present day Annulariidae. 2014 English text The Ohio State University / OhioLINK http://rave.ohiolink.edu/etdc/view?acc_num=osu1417706937 http://rave.ohiolink.edu/etdc/view?acc_num=osu1417706937 unrestricted This thesis or dissertation is protected by copyright: all rights reserved.
