How does migration influence biological diversity?
Migration has impacted natural resources for centuries, and will continue to do so causing species and genetic loss, habitat fragmentation, loss of ecological connectivity and disruption of evolutionary processes. Each migration is driven by a complex and unique set of drives, referred to as push and pull factors.

Migratory birds help in dispersal of seeds, leading to maintenance of biodiversity along their routes. Ducks can transport fish eggs in their guts to new water bodies. The droppings of birds, also known as guano, are rich in nitrogen and act as organic fertilizers.
How does migration affect the ecosystem?
There are many ecological implications of migration. The food resources of some regions would not be adequately exploited without moving populations. … As winter comes, food becomes scarce, and water birds migrate to the tropics, where the rainy season has caused food production to increase to optimal levels.
How does animal migration affect humans?
