Butterflyfishes as a model group for reef fish ecology: important and emerging research topics

[Extract] In his preface to a special issue (and dedicated workshop) on the biology of butterflyfishes, Motta (1989) suggested that butterflyfishes have received disproportionate scientific attention compared to other common and conspicuous families of coral reef fishes. In support of this assertion, the number of scientific publications that consider butterflyfishes (151 Web of Knowledge; 382 publications since 1927) is far greater than for many other families of nominal reef fishes (e.g., angelfishes, surgeonfishes, and rabbitfishes); the only families that have been more intensively studied are the Pomacentridae (damselfishes), Serranidae (groupers) and Labridae (parrot fishes and wrasses), which probably reflects their high diversity, commercial and functional importance, respectively. In this respect, research on butterflyfishes has contributed greatly to genera l understanding of the biology and ecology of coral reef fishes (e.g., Almany et al., 2007; Lawton et al., 2011). The fields of research in which butterflyfishes have played essential roles also extends well beyond the notion that butterflyfishes are "indicators" of overall reef health, which is the usual justification for studying this relatively unique group of reef fishes (e.g., Ohman et al., 1998; Bozec et al., 2005; Shokri et al., 2005)
