Abstract: We determined spatial patterns in distribution and biomass of 163 fish species in nearshore waters around Tutuila Island, American Samoa. Visual surveys of reef fishes along 30 by 5 m belt transects were conducted using a hierarchical nested design at five spatial scales from individual transects to tens of kilometers, allowing assessment of broad geographic patterns. Benthic cover data were derived from video transect surveys to test the relationship between habitat and ...

Variability in recruitment of coral reef fishes: the importance of habitat at two spatial scales.
Ecology
; INTRODUCTION Most marine organisms and virtually all coral reef fishes have a bipartite life cycle including a planktonic larval stage and relatively sedentary juvenile and adult phases (Breder and Rosen 1966, Sale 1980). In these open systems, input into a local population is not expected to be

Mortality of juvenile damselfish: implications for assessing processes that determine abundance.
Ecology
; INTRODUCTION Replenishment of demographically open populations has been examined extensively in marine reef fishes since, like most benthic marine species, they typically have early developmental stages that disperse in the plankton (Doherty and Williams 1988, Mapstone and Fowler 1988, Olafsson et

Epizootics and Disease of Coral Reef Fish in the Tropical Western Atlantic and Gulf of Mexico
Reviews in Fisheries Science
; A review of the published literature on coral fish epizootics and disease suggest that a variety of bacterial, viral, and fungal pathogens and several host-ectoparasite relationships can affect coral reef fishes and populations. Biotoxic organisms (e.g., Caulerpa), toxic dinoflagellates (e.g.,

Interspecific competition controls abundance and habitat use of territorial Caribbean damselfishes.
Ecology
; INTRODUCTION A central question in marine ecology arises from the fact that marine organisms often begin life as pelagic larvae: to what extent are marine benthic communities organized by interactions among benthic populations vs. the dynamics of the influx of pelagic recruits (e.g., Lewin 1986,
