What occurs when some elephants in a population migrate into another area and join another population?

When some elephants from one population migrate and join another, it can lead to increased genetic diversity within the new population due to the introduction of new genes. This can enhance the resilience of the population to diseases and environmental changes. Additionally, it might alter social structures and dynamics as the migrating elephants integrate with the resident group, potentially leading to changes in behavior and resource use. However, it can also introduce competition for resources if the populations were previously isolated.
