Synopsis An alternative to the reef fish lottery model is proposed for explaining instances of coexistence of reef fishes without apparent spatial resource partitioning. This model is termed money-in-the-bank because of a financial analogy used to explain it. It stresses the importance of habitats that can support only one of two or more closely related species that coexist elsewhere. Populations living in such monospecific habitats could, according to the model, produce enough larvae to repopulate these habitats plus an excess that may settle in the multispecific habitats. Possible examples among cardinalfishes are given.This paper forms part of the proceedings of a mini-symposium convened at Cornell University, Ithaca, N.Y., 18–19 May 1976, entitled Patterns of Community Structure in Fishes (G. S. Helfman, ed.). 相似文献
