Abstract
The current environmental crisis threatens biodiversity worldwide. Florida is one of the most biodiverse states in the United States of America, containing many unique and endangered species. Two of these species are the epiphytic bromeliads Tillandsia utriculata and T. fasciculata (Bromeliaceae), threatened by an introduced bromeliad weevil, Metamasius callizona (Coleoptera: Curculionidae). This study used species distribution models (SDMs), and microclimate data collection with data loggers to evaluate the effects of climate on distribution at large and fine scales, using two study sites: Myakka River State Park (MRSP) and Fairchild Tropical Botanic Gardens (FTBG), the former where the weevil has significantly reduced populations, and the latter where the weevil has not been reported. To supplement the quantitative data I collected, I also conducted interviews with 5 conservation professionals working on this project. This study demonstrated important variables for the distribution of Florida endangered plants and an introduced specialist herbivore. Secondly, it showed that it is important to pair these models with microclimate information to show distinct small-scale patterns. Thirdly, interviews with park managers and researchers demonstrated the ability for parks, botanical gardens, and universities to work together and solve conservation problems.
