Spatial variation in otolith elemental chemistry of Stegastes arcifrons (Pomacentridae) reflects environmental patchiness at the Galápagos archipelago

open access: yesJournal of Fish Biology, EarlyView.
Abstract In marine ecosystems, environmental conditions shape important ecological processes. The equatorial Galápagos Marine Reserve (GMR) is known for great spatial variation in the upwelling of cold nutrient‐rich waters and the input of warm Panamanian waters.
