dc.description.abstract Few studies have examined spatial variation in the demography or age structures of coral reef fishes. We analysed sectioned sagittal otoliths to describe the age structures, growth and mortality of 5 species of Stegastes damselfishes. These were sampled at localities near the centre (Panama) and at the northern (Baja California) and southern (Galapagos) edges of the eastern Pacific tropical reef environment. Widespread damselfishes were sampled at Panama and Baja (S, flavilatus) and at Panama and the Galapagos (S, acapulcoensis). The 3 remaining species were endemic to the Galapagos Archipelago (S, arcifrons, S. leucorus beebei) and Baja California (S. rectifraenum). We found that populations of widespread species in the Galapagos and Baja grew to larger adult sizes, had relatively long Life spans and lower rates of mortality once asymptotic mean sizes were attained than populations of the same species in Panama. These characteristics of long adult life spans and low mortality rates were shared by endemic species in the Galapagos and Baja. Our analysis revealed strong year classes that corresponded to the timing of El Nino-Southern Oscillation events in the age structures of both a widespread and an endemic species in the Galapagos Archipelago.
