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 .
Alongside the transportation innovations of globalization, the spread of biological technology has allowed the world to enter a new global economy. Because agriculture is such a huge economic sector it is large portion of the economy, and a large portion of that is the production of wheat in the last few centuries. Technically wheat is an ...
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.
For example, biodiversity is a source of food, medication, and materials used in industry. Recreation and tourism are also examples of human economic activities that rely on these benefits. In 2018, the WWF Living Planet Report argues that the whole global economy of US$125 trillion ultimately relies on nature. [3]
Animal migration is set apart from other kinds of movement because it involves the seasonal departure and return of individuals from a habitat. [59] Migration is also a population-level phenomenon, as with the migration routes followed by plants as they occupied northern post-glacial environments.
The migration of supply chain to third countries by Chinese, U.S., and European multinationals is an overlooked dimension of the emerging world order.
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.

DVM is important to the functioning of deep-sea food webs and the biologically-driven sequestration of carbon. [3] In terms of biomass, DVM is the largest synchronous migration in the world. [4] [2] It is not restricted to any one taxon, as examples are known from crustaceans , [5] molluscs , [6] and ray-finned fishes . [7]
