Using herbaria to predict climate change response: modeling Florida plant diversity.

Scientists have long realized that looking into the past is crucial for predicting the future. Florida hosts several biodiversity hotspots and is home to over 4,100 species of plants. Using herbarium collections, we reconstructed niche models for more than 2,700 terrestrial plant species from Florida and projected these models into the future. Mapping the index of plant diversity, distributions of different traits, and endemism hotspots, we examine the predicted future distributions of this diversity. Plant distributions were projected for 50 years, with consideration given to models of dispersal ability, sea level change, and land use predictions. The plant species, unexpectedly, show a strong movement southeastward, with two distinct regions responding differently to the future change in climate. Changes in precipitation seem to be stronger determinants of these responses than increasing temperatures. Furthermore, the regions with the greatest projected increases in species richness correspond to the most vulnerable to sea level rise, with important implications for conservation and land management of the peninsula. This study emphasizes the importance of museum collections in our ability to understand and predict future changes in biodiversity at the landscape level.
