Wildebeest migrating in the Serengeti. Migration, in ecology, is the large-scale movement of members of a species to a different environment.Migration is a natural behavior and component of the life cycle of many species of mobile organisms, not limited to animals, though animal migration is the best known type.
Animal migration is the relatively long-distance movement of individual animals, usually on a seasonal basis. It is the most common form of migration in ecology. It is found in all major animal groups, including birds , mammals , fish , reptiles , amphibians, insects , and crustaceans .
Plant migration, see Seed dispersal, the movement or transport of seeds away from the parent plant; Gene migration, a process in evolution and population genetics; Cell migration, a process in the development and maintenance of multicellular organisms Collective cell migration, describing the movements of group of cells
The migration of cultured cells attached to a surface or in 3D is commonly studied using microscopy. [7] [8] [5] As cell movement is very slow, a few μm/minute, time-lapse microscopy videos are recorded of the migrating cells to speed up the movement.
Collective cell migration describes the movements of group of cells and the emergence of collective behavior from cell-environment interactions and cell-cell communication. Collective cell migration is an essential process in the lives of multicellular organisms , e.g. embryonic development , wound healing and cancer spreading ( metastasis ). [ 1 ]
Reinforcement is the deliberate introduction and integration of an organism into an area where its species is already established. [1] This mode of translocation is implemented in populations whose numbers have dropped below critical levels, become dangerously inbred, or who need artificial immigration to maintain genetic diversity.

Diel vertical migration (DVM), also known as diurnal vertical migration, is a pattern of movement used by some organisms, such as copepods, living in the ocean and in lakes. The adjective "diel" (IPA: / ˈ d aɪ. ə l /, / ˈ d iː. əl /) comes from Latin: diēs, lit. 'day', and refers to a 24-hour period.
Migration in Lepidoptera means a regular, predictable movement of a population from one place to another, determined by the seasons. [2] There is no unambiguous definition of migratory butterfly or migratory moth, and this also applies to proposals to divide them into classes. [3] Migration means different things to behavioral scientists and ...
