High levels of biodiversity are generally considered a positive aspect of island environments, as they contribute to the ecosystem's resilience and stability.

Insular adaptation refers to the specific adaptations that species undergo in response to the unique challenges and opportunities presented by island environments.

The flightlessness of the dodo bird is an example of insular adaptation, as it evolved in response to the lack of predators on the island of Mauritius.

Island extinction refers to the phenomenon where species on islands are more likely to go extinct than species on mainland populations.

All of the above factors contribute to the high rate of island extinction.

Endemic species are those that are unique to a particular geographic region and are not found anywhere else in the world.

All of the above are examples of endemic species.

All of the above terms refer to the introduction of non-native species to an island environment.

All of the above are examples of invasive species that have had a negative impact on island ecosystems.

All of the above terms refer to the process of restoring a degraded island ecosystem to its natural state.

All of the above are examples of successful island restoration projects.

All of the above terms refer to the ability of an island ecosystem to withstand and recover from disturbances.

All of the above factors contribute to the resilience of island ecosystems.

All of the above terms refer to the process of managing and conserving island ecosystems to enhance their resilience.

All of the above are examples of successful island conservation projects.
