We report architectural divergence between two congeneric tropical tree species coexisting in the same stratum which suggests different strategies: reducing self-shading and support costs, or maximizing light foraging. We found species-specific differential performance across light environments, suggesting that architectural differentiation could facilitate the coexistence of species with similar vertical habitat.
