Simulating Species Richness Using Agents with Evolving Niches, with an Example of Galápagos Plants

Table 1

A summary of the parameters in the model, grouped into classes, their values, and their units. Values used were determined through exploratory analyses.

	Overlap in elevation	0.75	Proportion
	Overlap in slope	0.79	Proportion
	Habitat suitability coefficient	1.26	—
Mutations
	Rate of mutation	±0.33	Probability
	Mean	6	Niche units
	Standard deviation	4	Niche units
	Rate of rare mutation	±0.01	Probability
	Mean	25	Niche units
	Standard deviation	12	Niche units
Long-distance dispersal
	Dispersers per breeding	7	Seeds
	A coefficient	500	Cells
	B coefficient	0.002	—
Others
	Age of plants	12	—
	Cycles modeled	800	—
