The tropical region is the most diverse area of the world. But diversity is not spread evenly within the tropical region. The Neotropical realm (tropical Americas) stick out as being exceptionally diverse even within the tropics, containing the plurality of the world's tropical species. Understanding how geographic factors within the Neotropics contribute to this exceptional biodiversity provides a greater understanding for how biodiversity arises and is maintained. One long-known geographical contributor to speciation is island colonization. Species disperse onto islands, where isolation over time leads to an accumulation of differentiation and eventually speciation. In this way, islands are a great contributor to overall biodiversity. In the Neotropics there is a chain of islands named the Antilles that span from South America to North America, defining the Eastern boundary of the Caribbean sea against the Western continental boundary of North, Central, and South America. The Greater Antilles consist of large islands such as Cuba, Hispaniola (Haiti and Dominican Republic), and Jamaica. The Lesser Antilles consist of many small islands, such as Barbados, Grenada, and Trinidad and Tobago. This variety of island size, overall distance spanned by the islands (~3000km), and provision of stepping stones between two continents with very different floras (North and South America), creates a dynamic and interesting system to study biodiversity arising. One way for new species to arise is through hybridization. In plants, hybridization between closely related species is relatively common. Hybridization in the palm (Arecaceae) genus Coccothrinax appears to be rampant. Unfortunately, hybridization between species makes it difficult to define the species in the first place, as many intermediate varieties can exist. Therefore Coccothrinax has stumped taxonomists when attempts have been made to define species in the genus based on traditional trait-based methods. We aim to use genomic data for the species of Coccothrinax from across the Antilles to (1) define species, and (2) model their geographic evolution to better understand how the Antilles have contributed to biodiversity of the Neotropics. The data we have collected is target capture genomic data. We have previously produced a Bayesian phylogeny for the genus, but now have more samples to add to the phylogeny. This compute project will be uses to add the additional samples to the phylogeny, and model geographic evolution.
