The role of fruit crop size, diversity of avian frugivores and long-term temporal variation over seed dispersal effectiveness in a neotropical savanna
(Universidade Federal de São Carlos, 2020-03-20)
Fruit crop size may be a key-trait for attracting an abundant and diverse assemblage of dispersers, possibly leading to positive outcomes for seed dispersal effectiveness (SDE). Temporal changes in resources or frugivore ...
