meta-population theory

Meta-population theory describes how groups of local populations of the same species are interconnected through movement and gene flow. Imagine several small populations living in nearby areas; if one declines or disappears, it can be recolonized by individuals migrating from neighboring populations. This dynamic balance helps species survive in fragmented or changing environments. The theory emphasizes the importance of habitat connectivity for maintaining overall population stability, recognizing that while local groups may fluctuate or go extinct temporarily, the broader metapopulation can persist through these interactions.
