| We study the occurrence and consequences of "contagious dispersal" and "apparent competition" in the tropical moist forest of Barro Colorado Island (BCI), Panama. Aims are to (1) determine to what degree seed dispersal is spatially contagious, (2) investigate the consequences of contagious dispersal for patterns of seed survival and seedling establishment, and (3) evaluate whether contagious dispersal and apparent competition can promote tree species coexistence. |
