Introduced birds incompletely replace seed dispersal by a native frugivore.

Pejchar L - AoB Plants (2015)

Bottom Line: Seed rain was significantly greater and more species rich at sites with Omao.These findings suggest that patterns of seed dispersal are altered following the local extinction of a native island frugivore.In an era of widespread extinction and invasion of island ecosystems, understanding the consequences of novel animal assemblages for processes like seed dispersal will be critical for maintaining diverse and self-regenerating plant communities.

PLV072F2: Seed rain (least squares means) under a wind-dispersed canopy tree (M. polymorpha) and under fleshy-fruited plants at sites with and without Omao.

Mentions: The two-way analysis of variance yielded differences in seed rain among sites, trap locations and the interaction between those two main effects (F(3,8) = 22.6; P< 0.0003). Seed rain differed by site type (sites with and without Omao; P < 0.0003), and trap location (under bird-dispersed fleshy-fruited plants or wind-dispersed canopy trees—M. polymorpha; P < 0.0128). The interaction effect (site type × trap location) was also significant (P < 0.0017); more seeds were collected under M. polymorpha at sites with Omao (Fig. 2).Figure 2.
