Effect of Elevated Temperature on the Metabolic Activity of the Coral Reef Asteroid Acanthaster planci (L.)

摘要: Standard rate of oxygen uptake in the coral reef asteroid Acanthaster planci(L.) was determined for temperature range of25° to 33° C and a metabolic rate-temperature (M-T) curve drawn. planci is con­ former. The increased with increase 31 ° C. decreased at C, which slightly above ambient laboratory-reared Acanthasterplanci tested. decrease indicates disturbance activity due elevated temperature. incipient thermal death point estimated be near animals did not maintain normal behavior feeding resting cycles. Increasing modification conditions by human would pose hazard maintenance communities if represents conformer invertebrates narrow tolerance
