Colonization and Extinction balance in the Island Biogeography Equilibrium model
Description
Simulate the balance between extinction and colonization rates given the equilibrium number of species in a island, based on the Island Biogeography Equilibrium model.
between 0-1. The minimum value of the extinction and colonization rates.
max
between 0-1. The maximum value of the extinction and colonization rates.
cycles
number of cycles in the simulation.
Ext
a string representing the extinction rate. This can be 'crs' for an increasing extinction rate, 'fix' for a fixed extinction rate in 0.5, or 'dcr' for a decreasing extinction rate.
Col
a string representing the colonization rate. This can be 'crs' for an increasing colonization rate, 'fix' for a fixed colonization rate in 0.5, or 'dcr' for a decreasing colonization rate.
Details
The number of species is the balance between extinction and colonization rates at the equilibrium.
Value
'animaColExt' returns a graph of the extinction and colonization rates varying one or both rates in relation with the number of species of an island.
