Lebanon Biogeography Outlined by Tree and Shrub Species Distribution Pattern.

ABSTRACT: To delineate the biogeographic structure of Lebanon based on native tree and shrub species distribution using ecological niche modeling and dissimilarity indices. Lebanon, Middle East, and Mediterranean basin (34° N-35° W). We compiled a species list of Lebanon phanerophytes and used ecological niche models (ENM) to obtain surface distributions for each species. Then we defined groups of species with overlapping whole distributional ranges (global chorotypes) and significantly similar distributions within Lebanon (regional chorotype). To evaluate spatially grouped sets of species, we mapped the predicted distribution of species belonging to each chorotype. We measured the biogeographic distinctness amongst them using turnover and nestedness indices. Finally, we identified biogeographic tra
