====== Island Biogeography - Tutorial for EcoVirtual ======

===== MacArthur & Wilson equilibrium =====

In {{:ecovirt:rlogo.png?20|}} load the EcoVirtual package. We will use the function **animaColExt** to see the colonization and extinction processes. This function has 2 parameters:

^Parameter^ definition^ options ^
|Ext| extinction rate | 'fix' - stable rate; 'crs' - increasing rate; 'dcr' - decreasing rate| 
|Col| colonization rate| ' 'fix' - stable rate; 'crs' - increasing rate; 'dcr' - decreasing rate|


Selct the options **Ext='fix'** and **Col=fix** and see what happens! Now try to change between states of **Ext** e **Col**.What happens with the equilibrium point in each combination? Why?


===== More islands ====


{{section>en:ecovirt:roteiro:neutr:biogeo_base#more_islands}}

We will use the function **bioGeoIsl** to combine the islands and see if, in the end, you can find the species-area relationship, our first step. By the way, this theory was created to explain species-area relationship. ;-)
