The conclusion drawn from the experiment involving the manipulation of habitat patches of springtails that live on moss is that even small barriers to recolonization raise extinction rates of subpopulations. This is in line with the concept of metapopulation dynamics, where subpopulations are connected by dispersal and recolonization events, and even small disruptions in this process can lead to higher extinction rates. The other options, A and C are not supported by the experiment described.
