Lining up an exterminator, getting the right technique… we pulled it off. We actually followed the recolonization of an empty island, in fact a whole series of them, with controls, and that was the first experiment in island biogeography. And although the data had certain limitations — we couldn’t really figure out the turnover rate exactly — we did affirm the main conclusions of the theory of island biogeography. The closer the island is and the smaller it is, the more quickly it fills up. The farther away it is, the larger it is, the more slowly it fills up. We learned a lot about the colonization of our islands in that experiment. It was very satisfying.
