The pollination service provided by animals is central for seed production in biotically-pollinated plants. Thus, changes in pollinator diversity associated with habitat loss may affect plant reproduction. On the other hand, plant reproductive systems determine the degree of dependence of plant species on pollinators for pollen deposition modulating plant resilience to pollinator extinction. Indeed, plants and pollinators are immersed in complex networks of interactions. The objective of this study is to evaluate how reproductive systems influence plant species persistence in fragmented landscapes and how this modulates the robustness of plant-pollinator networks to habitat loss, by combining mathematical models, empirical data and metrics of interaction networks. This objective will be achieved throughout the evaluation of how plant reproductive systems influence the role of species in empirical plant-pollinator networks. Indeed, we will modify the model for metacommunities in fragmented landscapes proposed by Fortuna & Bascompte (2006) to study species persistence in mutualistic networks. The new model will explicitly include the influence of plant reproductive systems on plant colonization and extinction rates. The dynamics of the model parameterized with empirical data about plant reproductive systems will be compared to that observed in the original model proposed by Fortuna & Bascompte (2006)-i.e. where colonization and extinction rates are assigned at random. This study may contribute to the understanding of how the biological traits of species modulate network robustness to habitat loss. Indeed, the results of this study may act as a theoretical base to planning conservation strategies for a key ecosystem service such as pollination.
