Abstract

Adaptation and diversification in species-rich systems are increasingly recognized as relevant processes to improve our understanding on biodiversity. This project investigates how natural selection related to ecological interactions shapes the structure, dynamics and diversification of mutualistic assemblages. First, we model how mutualism and intraspecific competition generate antagonistic selective regimes that define patterns of diversification. Subsequently, we evaluate whether the adaptive rewiring of ecological interactions can explain the structural variation of mutualistic networks. Finally, we investigate effects of different modes of speciation on mutualistic network properties.
