Migration in organisms refers to the directed, typically seasonal or life-stage–dependent movement of individuals or populations between distinct geographic regions, often driven by spatiotemporal variation in resources, breeding opportunities, or environmental conditions. It is characterized by relatively long-distance, persistent movements with clear origin and destination areas, underpinned by evolved orientation and navigation mechanisms (e.g., celestial, geomagnetic, olfactory cues). Migration can be obligate or facultative, partial or complete within a population, and plays critical roles in gene flow, metapopulation dynamics, ecological connectivity, disease spread, and responses to climate and habitat change across taxa including animals, plants (via propagule movement), and microorganisms.
