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?

Answer 1

Distance to island

Step-by-step explanation:

• As per the theory of, the island biogeography the number of the species that are found in an undisturbed island environment are determined by the immigration and extinction of species.

• And if an invasive species emigrated from the mainland it would likely to experience a decline due to the distance effects that islands which are isolated more is less likely to get immigrants than an island with less isolation.

Answer 2

Based on the theory of island biogeography, the one that would most likely experience the greatest decline of specialist species if an invasive species emigrated from the mainland is a small island in close proximity to the mainland

For better understanding let's explain what island biogeography means

• Island Biogeography is simply known as acquiring relevant knowledge or skills about the sharing or distribution of species and community structure on various islands

• Equilibrium theory of island biogeography was said to be published by Robert MacArthur and Edward Wilson in 1967. it was divided into Size effect, Distance Effect and Equilibrium number

• Distance Effect covers the number of species that reduces with close distance to nearest land mass like the case of our answer above.

from the above we can therefore say that the answer Based on the theory of island biogeography, the one that would most likely experience the greatest decline of specialist species if an invasive species emigrated from the mainland is a small

in close proximity to the mainland, is correct
