Question

highly specialized species tend to evolve on islands because of the environmental conditions and resource availability. based on the theory of island biogeography, which of the following would most likely experience the greatest decline of specialist species if an invasive species emigrated from the mainland? a a small island a far distance from the mainland b a small island in close proximity to the mainland c a large island a far distance from the mainland d a large island in close proximity to the mainland

Explanation:

According to the theory of island biogeography, small islands have fewer resources and less diverse habitats. Specialist species on small islands are more vulnerable. Islands close to the mainland are more likely to receive invasive species (due to shorter distance for migration). So a small island close to the mainland would have specialist species most affected by an invasive species from the mainland.

Answer:

B. A small island in close proximity to the mainland
