What would a scientist predict to occur on large islands located near the mainland,based on the theory of island biogeography? 

A)  high immigration and low extinction rates 
B)  low immigration and low extinction rates 
C)  low immigration and high extinction rates 
D)  high immigration and high extinction rates

According to the theory of island biogeography, larger islands located near the mainland have higher immigration rates due to their proximity to the source population on the mainland. Additionally, larger islands have more habitats and resources for species to occupy, decreasing the likelihood of extinction. Therefore, a scientist would predict high immigration and low extinction rates on large islands near the mainland.
