How does migration affect animals?
But migration can have another important benefit. By allowing animals to escape from habitats where parasites have accumulated and by weeding out infected individuals that are not able to survive the journey, migration can reduce parasite infection in animal populations.
What are the effects of climate change to migratory animals?
Changing rainfall patterns are causing dams to be erected in some areas of our planet, not taking into account the migratory fish and mammals that annually migrate up river to breed and spawn and water birds which rely on wetland sites for migration are at threat from rising sea levels caused by human effects.

How does animal migration affect biodiversity?
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.

The main reason an animal hibernates or migrates is due to the lack of food, which occurs during the winter months due to the cold weather. In the fall, animals get ready to hibernate by preparing for the winter. They eat extra food and begin storing it as body fat. They use this fat for energy while hibernating.

Animal migration is the relatively long-distance movement of individual animals, usually on a seasonal basis. The cause of migration may be local climate, local availability of food, the season of the year or for mating.
How do migratory animals affect ecosystem processes?
Migration, in particular, affects biodiversity at regional and global scales, and migratory animals affect ecosystem processes. Animals use predictable environmental cues for the timing and navigation of migration.
What is animal migration?
Animal migration is a pattern of behavior in which animals travel from one habitat to another in search of food, better conditions, or reproductive needs. Many different animal species migrate, and there are many different types of migration.
