The study of interaction networks promotes the understanding of species interactions, their spatio-temporal dynamics and some determinant processes behind. Here, I analyze how plant-hummingbird interaction networks change over time and space, either when affected by extreme climatic events such as hurricanes, or by habitat modifications due to human activities such as agriculture, pasturing and urbanization. Furthermore, I evaluate the importance of species abundance, and phenological and morphological overlap as factors determining hummingbird-plant interaction frequencies and network attributes
