Mutualistic interactions along a fragmentation gradient

Forest cover loss and fragmentation due to land use changes are one of the principal causes of global biodiversity loss. Indirectly, forest fragmentation can reduce biodiversity and ecosystem functioning by disrupting species interaction networks. Interaction networks, such as seed dispersal networks, are fundamental in maintaining ecosystem services. In tropical forests, frugivorous animals are the most important seed dispersers and thus the main agents of forest regeneration. In general, large tree species produce large seeds that are dispersed by large frugivores. Therefore, in absence of large frugivores, the average size in the tree community is hypothesized to eventually decrease whic…
