Aerobic scope and temperature preference in yellow tang (Zebrasoma flavescens) at current and elevated sea temperatures.

ABSTRACT: Climate change is predicted to continue elevating regional sea surface temperatures (SST) and increase the frequency and severity of localized heating events, phenomena which may threaten the biodiversity, integrity, and function of tropical coral reef ecosystems. The primary objective of this study was to determine physiological and behavioral responses to elevated SST in a Hawaiian surgeonfish, the yellow tang, Zebrasoma flavescens. We assessed standard metabolic rate (SMR), maximum metabolic rate (MMR), aerobic scope (AS), and swimming performance, as well as temperature preference (T_pref) in this ecologically and economically important coral reef fish. The Z. flavescens were acclimated to either the current maximum monthly summer SST around O'ahu, 27 °C, or an elevated SST,
