New Publication: Who disperses tree seeds in fragmented landscapes?

Many plants rely on frugivorous animals for seed dispersal. In fragmented landscapes, frugivore communities can change from forest to matrix due to species loss or replacement in open anthropogenic habitats, and such changes have potential consequences for the plants they disperse. In our new paper in PNAS, led by Juan Pedro González-Varo, we report a similar diversity of frugivores, plants, and interactions contributing to seed dispersal in forest and matrix habitats from seven fragmented landscapes across Europe. However, we found a substantial turnover of both species and interactions. This turnover entailed functional changes toward larger and more mobile frugivores in the matrix that dispersed taller, larger-seeded plants with later fruiting periods. Our study provides a trait-based understanding of frugivore-mediated seed dispersal in anthropogenic landscapes and can inform ecological restoration.
