Animal dispersal refers to the movement of animals from their birthplace to new locations where they can establish their own territories or find resources. This process is crucial for species survival, as it helps reduce competition for food and mates, and allows for genetic diversity within populations. Dispersal can occur through various methods, including walking, flying, or swimming. Different species have unique dispersal strategies. For example, birds often migrate long distances to find suitable habitats, while small mammals may use their sense of smell to locate food and shelter. Additionally, some animals, like sea turtles, travel vast ocean distances to return to their nesting sites, showcasing the importance of dispersal in maintaining healthy ecosystems.
