Abstract
Protecting tropical rain forests (TRFs), home to half of the worlds plant diversity, is essential for mitigating the global biodiversity crisis. TRFs not only exhibit an impressive taxonomical diversity (TD) but are also renowned for their diverse morphological traits, indicating high functional diversity (FD). However, our knowledge of the spatial patterns of their TD and FD remains incomplete, severely impeding our ability to implement effective conservation measures. In particular it remains unclear is both these dimensions of diversity overlap or not across global scales. To address this issue, we assembled the most comprehensive distribution and morphological traits datasets within Annonaceae, a diverse and ecologically important pantropical family. We examine spatial correlations between TD and FD, and overlap the hotspots of both to identify the hottest hotspots. We further assess the current protection and threat status of these hotspots by overlaying them with protected areas, global tree cover loss and regional land use datasets. The hotspots exhibiting high levels of both TD and FD, lack of protected areas, and high coverage of disturbed areas should be given utmost priority in tropical rain forest conservation efforts.
