There are two issues with these assumption: the pioneer
organisms are specialists, so the expanding wave front
is different than the volume behind, which will have
succession colonization waves, and then settle into
a high-diversity equilibrium.

Regardless of origin, in a mature system the diversity
is sufficiently high that any random sampling will result
in very dissimiliar organisms, though there will be
convergent evolution for specific niches (the most
important one being the pioneer niche).
