Colorimetric Detection of Caspase 3 Activity and Reactive Oxygen Derivatives: Potential Early Indicators of Thermal Stress in Corals

Figure 9

Catalase activities measured as hydrogen peroxide leftovers in Pocillopora damicornis coral host fractions () in control (26°C); recovery treatment (ramping from 26°C at day 0 to 32°C at day 6 then cooling to 26° at day 9); and stress treatment (ramping from 26°C at day 0 to 32°C at day 6) during 16 days.
