Metapopulations are indeed characterized by all three aspects mentioned: (I) They can form as a result of habitat fragmentation, which divides a larger population into smaller, isolated groups. (II) The dynamics of metapopulations are influenced by the balance between the rates of local extinctions and the colonization of new habitats. (III) The basic metapopulation model, for simplicity, often assumes that all habitat patches are of equal quality, although in reality, this may not be the case.
