Allee effect and metapopulations

[rudy benavides]

"Jean-Michel MAES" wrote..."That's also very important when a forest is
cutted in small pieces, then you have no more a large habitat but a big
quantity of small habitat and each small habitat can suffer by Allee effect.
Very important for protected area planification."
 
An example from the world of birds is that with fragmentation of a forest
there is an increase in edge effect which leads to greater predation.  This
has been verified as taking its toll on many nesting birds.  Does this apply
in the world of lepidoptera and insects as well?
