A species of frog is found separated into many subpopulations living in ponds that are surrounded by agricultural fields. Sometimes one frog subpopulation goes extinct because of disease or environmental stochasticity. Frogs from other subpopulations will occasionally move across fields to recolonize ponds where subpopulations have gone extinct. This is an example of

The occasional recolonization of extinct ponds through movement of frogs from other subpopulations is an example of metapopulation dynamics. The other answer choices do not accurately describe this scenario.
