Biodiversity patterns and conservation of Caribbean sendemic trees

Caribbean islands represent one of the world's most threatened biodiversity hotspots, with approximately 60% of documented extinctions occurring in these territories. Endemic trees, which are fundamental components of Caribbean ecosystems, face multiple threats including habitat destruction, climate change, and biological invasions. This research project aims to develop a comprehensive understanding of Caribbean endemic tree biodiversity and establish effective conservation strategies through three interconnected objectives. The project will analyse biodiversity patterns of Caribbean endemic trees and their driving factors. Using an integrated approach combining spatial analysis, ecological niche modelling, and statistical tools, the study will examine how endemic tree diversity varies across islands and habitat types. This analysis will incorporate environmental variables, geological history, and human impacts to understand current distribution patterns and predict future changes under different climate scenarios. The second objective involves assessing the conservation status of Caribbean endemic trees using IUCN criteria, complemented by genetic analyses. This assessment will evaluate population sizes, distribution ranges, and threat levels while considering traditional uses and local management practices. A representative subset of 15-20 species will undergo detailed genetic analysis to understand patterns of genetic erosion and establish minimum viable population sizes for conservation. The third objective focuses on identifying and evaluating Important Plant Areas and biodiversity hotspots for endemic trees in the Caribbean. Using a standardized methodology that integrates species richness, conservation value, and habitat status, the research will map priority areas for conservation and assess the effectiveness of existing protected areas. This analysis will consider both ecological and socioeconomic factors to ensure practical and sustainable conservation outcomes
