Methods of Dispersal Fruit and seeds may be scattered (dispersed) in different ways depending on their environment and characteristics. Compared to mammal‐dispersed species, bird‐dispersed fruits show stronger phenotypic integration in morphological traits, probably as a result of their strong selection on fruit/seed size and mass due to their limited ability to exploit fruits larger than their gape width (Valido, Schaefer, & Jordano, 2011). 2.
