Hi Rolf,

You might already point it out, but effective population size can also influence neutral genetic differentiation, not just neutral genetic diversity.  (In fact: Are you explaining the difference between diversity and structure, or is someone else?)  I feel that’s often overlooked in current studies…we mostly focus on the landscape in-between samples, but location-specific factors can also influence gene flow (e.g., density-dependent dispersal, reproduction and survival).  Thus, if we have populations of varying sizes/densities, we might expect certain genetic structures, even if gene flow is not influence by space or the matrix.  (And this might actually tie in niceley with the net-work approaches discussed by Melanie in lecture 9.)

Looks great otherwise!
