Ruben Heleno will contribute with experience in the construction and analysis of seed dispersal networks, including multilayer networks. RH has 15 years of experience working on seed dispersal networks, particularly on islands, and on using ecological networks to inform conservation efforts and to advance ecological and biogeographical theory. He is particularly interested in exploring ways to jointly consider the functional roles of frugivorous and non-frugivorous seed dispersers and on evaluating the relevance of diaspore adaptations to favor long-distance dispersal mechanisms. RH is also interested on the role of fruiting phenology and long-distance bird migration on plant recruitment and hence on future forest composition at continental scales. He will collaborate on all steps of the research, including on the identification of the main knowledge gaps, the definition of the best methodologies to tackle them, data acquisition and on the analysis, interpretation, and communication of the project result.
