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.

PLV072F1: Seed rain from four fleshy-fruited species (number of seeds/50 trap day adjusted for per cent cover of plant species; mean ± SD) at sites with and without Omao.

Mentions: There was significantly more R. hawaiiensis and C. trigynum seeds dispersed (relative to per cent cover of each plant species) at sites with Omao (R. hawaiensis: t = 7.7; df = 3; P = 0.004; C. trigynum: t = 3.5; df = 3; P = 0.04; Fig. 1). Vaccinium calycinum seeds were only dispersed at sites with Omao; this species was not observed in fruit at non-Omao sites during the study season [see Supporting Information]. Ilex anomala seeds were only dispersed at the sites with Omao (Fig. 1), despite no difference in I. anomala per cent cover or fruiting among the sites with or without Omao [see Supporting Information].Figure 1.
