Density Dependent Seed Survival
This behavior assesses seed survival as a function of the local density of conspecific seeds.
Parameters for this behavior
How it works
This behavior takes the seeds that have been dispersed to each grid cell of the Dispersed Seeds grid and calculates how many will survive. The number of seeds that survives is calculated as
Once the number of surviving seeds has been determined, the behavior assigns that number back to the Dispersed Seeds grid cell. If there is only one seed in a grid cell, it always survives.
How to apply it
Apply this behavior to seeds of your desired species. Any species to which it is applied must also have any disperse behavior applied.
