Larger islands typically exhibit:
“Lower extinction rates” for larger islands typically exhibit. This relationship follows from the ecological mechanism represented by the terms in the item, not merely from an association between their names. Island biogeography explains species richness as a dynamic balance between immigration and extinction. Immigration generally declines as an island fills with species, whereas extinction rises as more species divide finite area and maintain smaller populations. The remaining alternatives—“Higher immigration rates”, “Lower immigration rates”, “Higher predation rates”—refer to different stat
