migration
migration 1. The movement of individuals or their propagules (seeds, spores, larvae, etc.) from one area to another. Three cases may be distinguished:
a. emigration, which is outward only
;
b. immigration, which is inward only
; and
c. migration, which in this stricter sense implies periodic two-way movements to and from a given area and usually along well-defined routes. Such migratory movement is triggered by seasonal or other periodic factors (e.g. changing day-length), and occurs in many animal groups.
2. In plant
succession, specifically the arrival of migrating propagules (migrules) at a newly denuded area.
