- rl
Object of class 'landscape' or 'metapopulation'.
- rlist
List delivered by span.graph
.
- simulate.start
TRUE (rl is of class 'landscape') or FALSE (rl is of class 'metapopulation')
- method
One of the following:
click - individually select the patches with occurrence of the species by clicking on the map. Use only for individual landscape simulations. However, this option should not be used with iterate.graph.
percentage - percentage of the patches to by occupied by the species.
number - number of patches to be occupied by the species.
To be internally passed to species.graph
.
- parm
Parameter to specify the species occurrence - either percentage of occupied patches or number of occupied patches, depending on the method chosen. To be internally passed to species.graph
.
- nsew
'N', 'S', 'E', 'W' or none - point of entry of the species in the landscape. By default set to "none". To be internally passed to species.graph
.
- succ
Set the preference of the species for patch successional stage: 'none', 'early', 'mid' and 'late'.
- param_df
Parameter data frame delivered by parameter.estimate
, including:
alpha - Parameter relating extinction with distance.
y - Parameter y in the colonization probability.
e - Parameter defining the extinction probability in a patch of unit area.
x - Parameter scaling extinction risk with patch area.
To be internally passed to simulate_graph
