摘　　要：Natural native forests are rapidly being replaced by anthropogenic forests often with a strong presence of invasive alien plant species.Eucalypt species are widely planted worldwide,with Eucalyptus globulus plantations being par-ticularly expressive in Portugal.Poor forestry practices often lead to the associated expansion of invasive species,such as Acacia dealbata.However,we still know relatively little about the functioning of anthropogenic forests,such as seed and pollen dispersal services.Here,we compared bird abundance and richness and the seed and pollen dispersal networks in both forest types.Anthropogenic forests presented lower bird abundance,and smaller,more simplified,and more random(abundance-based)seed dispersal services than those of natural forests.Interestingly,the pollen dispersal network was more similar than the seed dispersal network for both forest types and domi-nated by opportunistic and neutral processes,given the absence of specialized nectarivorous.The proportion of birds transporting seeds decreased,while those carrying pollen significantly increased in the anthropogenic forest compared to the native forest.Our work highlights the impact of anthropogenic forests on bird abundance,with consequences for seed dispersal services and forest regeneration.
