1 In the colonization of an island by potentially interacting species both the severity of the competition between them and the length of the interval between their arrivals should affect the likelihood of the second species becoming established. Between‐island variation in priority and the interval between colonizations will depend on the dispersal rates of the two species. 2 We predict that early colonization should be relatively deterministic, whereas later in the colonization process both the sequence of arrivals and the interval between them will be more variable. 3 Possible instances of both deterministic and stochastic stages in community development are identified in the colonization of the Krakatau islands by zoochorous forest trees and large zoochorous lianes.
