Abstract

[Extract] Experimental studies of effects of disturbance on coral-reef fishes have generally been limited to direct disturbances - ie. defaunation (eg. Sale and Dybdahl 1975, 1978; Molles 1978). While natural occurrences of these types of disturbance have been recorded (Bohnsack 1983; Lassig 1983; Walsh 1983), most of the applications of defaunation have been used ostensibly to explore rules of community organization. Indirect disturbances, such as habitat alteration, have received far less experimental attention in tropical studies. Much of this disinterest in habitat disturbanee may be a result of the weakness of correlative evidence of fish-habitat association, especially at the patch-reef scale (Sale et al. 1994). In contrast, habitat manipulations have been widely and successfully applied to temperate reef fish assemblages and generally have demonstrated that habitat is an important structural element (Choat and Ayling 1987; Bodkin 1988; Jones 1984; DeMartini and Roberts 1990; Holbrook et al. 1990; Carr 1989, 1991; Syrns and Jones in prep.). In this study, we re-evaluate the importance of disturbance to fish assemblages on small patch reefs and compare the relative effects of direct vs. indirect disturbances.
