OBJECTIVE FORESTRY

Detailed explanation-1: -Assuming all new species have to immigrate to the island from the mainland, closer islands will have more species on them than far islands, just because closer islands are easier to reach. Extinction is lower on islands close to the mainland because of the likehood of immigration.

Detailed explanation-2: -You should see that the highest species richness occurs on a large island near the mainland: the lowest on a small island far from the mainland. The highest turnover rate occurs on small island near the mainland: the lowest on a large island far from the mainland.

Detailed explanation-3: -Larger islands contain larger habitat areas and opportunities for more different varieties of habitat. Larger habitat size reduces the probability of extinction due to chance events. Habitat heterogeneity increases the number of species that will be successful after immigration.
