Sizes of patches 
alpha 
Decay parameter of the exponential connectivity equation

locations 
Locations of patches. If missing, the locations are found from metric scaling of distances. 
cex 
Character expansion factor for the largest dot; the other dots are scared proportional to the patch area.

=ther parameters to the functions 
Metapopulation capacity is defined as the largest eigenvalue of matrix with nondiagonal elements A_i \exp(α d_{ij} A_j and zero diagonal.
