Storm Light Dependent Seed Survival
This behavior assesses seed survival as a function of the light level of the location in which a seed lands. Light level calculations are performed by the Storm Light behavior. (This behavior is exactly like Light Dependent Seed Survival except for the method of light level calculation.)
Parameters for this behavior
How it works
The effects of light levels on seed survival is graphed as:
To assess the effects of light level on the number of seeds that survive, this behavior retrieves the light level from the Storm Light grid that corresponds to the point in the center of each Dispersed Seeds grid cell.
The proportion of seeds that survive for a given species is calculated as:
Once the proportion of seeds that survive at the given light level has been calculated, this value is multiplied by the number of seeds to reduce them by the proper amount. The new reduced number of seeds is put back in the Dispersed Seeds grid.
