Characteristics of vertebrate-dispersed fruits in Hong Kong 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. Characteristic of other fruits in dispersing their seeds Some plants or fruits are` explosive, when the seeds are ready to grow the fruits explode and scatter the seeds.
