Meta-population is the patchiness of population in space and its role is dynamic, population insatiability, coexistence of species, the maintenance of diversity.
Metapopulation is colonization and extinction dynamics. The variable of prime concern is the proportion.As the population largest approaches the environment carrying resources become more scare and growth rate slows.
The m maxima carrying number of species in environment can support indefinitely .A group of spatially separated population of similar organism which interact at some levels.It s population in which multiple populations as butterflies and cool reef fishes.Humans are evolved from multiple interconnected spread out across Africa in large meta-population.
