Methods of animal propagation on islands

Animals spread to the island in different ways. This process is very interesting. Knowing the history of animals is also exciting.

Distribution of animals on islands

Corridors: Corridors are wide stretches of land connecting islands and the mainland. In the distant past, islands connected to the mainland by corridors brought fauna from the mainland. A mixed fauna is noticeable due to the lack of current connectivity.

Filter Breeze: It is smaller than the corridor and acts as an impenetrable wall for the spread of some organisms. However, the dispersal of animals through filter bridges is relatively selective. For example, this is how polar bears spread from Europe to North America.

Whipstake Bridge: This type of bridge is constructed using floating logs, and rafts of leaves. The spread of animals through this is very dangerous. Such spread occurs in rodents.

Airflow: Airflow plays an important role in the spread of birds and insects.

Through humans: In this case, humans play a major role in animal propagation. This is how cockroaches spread.

Through flying animals: Bats, birds, and other flying animals are attached to the wings or feet of many animals such as snail eggs, and the molecules of various organisms are spread to distant islands through mud sticking to their organs.
