| | Mode of seed dispersal greatly shapes placement of rainforest trees |
 | | Each species was categorized by one of five dispersal methods: ballistic (where seeds are liberated explosively), gravity, gyration (where the progression of seeds to the ground is slowed by the shape of the seeds), wind, and animal, the last of which was sub-categorized by fruit size. |
 | | Upon comparison across all species and seed dispersal categories, they determined that trees with ballistic dispersal methods tended to have the tightest cluster size, with trees dispersing their seeds via gravity, gyration, wind, and fruit of increasing size showing progressively more diffuse spatial distributions. |
 | | Wind-dispersed seeds were observed to have a surprisingly tight cluster radius, likely explained by the dense forest canopy stifling wind speeds. |
