In a study of these ecosystems, Daniel Simberloff and his advisor fumigated arthropods with methyl bromide. That study supported an equilibrium theory of these ecosystems that models the relationship of immigration and extinction to the number of species within them. r/K selection theory (15[1])was popularized by a book about these ecosystems that prompted Jared Diamond (15[1])to propose rules for designing protected areas during the SLOSS debates. Foster’s rule states that the (*) size of species in these ecosystems (10[1])skew towards the extremes. Peter and Rosemary Grant conducted longitudinal studies in one of these ecosystems to study drought responses and their effect on adaptive radiation. Robert MacArthur and E. O. Wilson wrote a book on the “biogeography” of these ecosystems. For 10 points, name these ecosystems that comprise archipelagos. ■END■
