My work explores the spatiotemporal variability of functional diversity of tropical dry forests and their conservation implications. Specifically, it is motivated by a fundamental question: How do tropical dry forest species move, survive, and adapt across spatial scales? An initial observation—that larger-seeded species tend to dominate Caribbean dry forests—prompted deeper eco-evolutionary questions. These questions led to the definition of two main projects. In particular, one project evaluates the macroecological dominance of certain dispersal strategies, while the other assesses how these strategies change over time at the local scale. These projects offer key insights into the tropical dry forest dynamics at different scales, revealing the processes that have shaped its distinctive spatial structure and diversity patterns.
