The onset of precipitation mediates plant–avian disperser interaction in recalcitrant seeds: the case of Cryptocarya alba (MOL) Looser, in Mediterranean ecosystems, Central Chile

摘要: Background: Arid and semi-arid environments impose limitations on plant regeneration. This is especially important during biotic dispersal in plants with recalcitrant seeds, relation to when where birds disperse these seeds. Aims: We examined the effect of onset seasonal precipitation regeneration Cryptocarya alba (Lauraceae), comparing seedling recruitment early late precipitations. Methods: conducted field experiments using bird-dispersed gravity-dispersed seeds; half seeds were placed initiation precipitations; other was kept, then forest ground 2 months later. compared probability among treatments. Results: Seedling positively affected by avian dispersal. significantly increased only for fraction that matched beginning Conclusions: The ecological context as well seed recalcitrance a...
