- High light alongside elevated PCO2 alleviates thermal depression of photosynthesis in a hard coral (Pocillopora acuta)
Summary: Ocean chemistry, light and temperature are changing under climate change. These changes have a synergistic impact on metabolic processes involved in energy acquisition in a coral–algal symbiosis.
- Paracellular transport to the coral calcifying medium: effects of environmental parameters
Summary: Paracellular transport in S. pistillata was investigated using calcein imaging. Changes in paracellular permeability could form an uncharacterised aspect of the physiological response of S. pistillata to seawater acidification.
- Emergent properties of branching morphologies modulate the sensitivity of coral calcification to high PCO2
Summary: Decades of experiments with coral nubbins reveal strong physiological responses to temperature and PCO2. Similar effects do not occur in intact colonies (5–21 cm) of branching corals.
- Size-dependent physiological responses of the branching coral Pocillopora verrucosa to elevated temperature and PCO2
Summary: Physiological performance of large corals is not accurately estimated by scaling values from small corals, indicating the importance of colony size in the response of branching corals to elevated temperature and PCO2.
- Effects of elevated pCO2 and feeding on net calcification and energy budget of the Mediterranean cold-water coral Madrepora oculata
Summary: Madrepora oculata show a threshold for calcification at an Ωa of 0.92 and there is no mitigating effect at increasing pCO2 due to more food supplied.
- The implications of reduced metabolic rate in resource-limited corals
Summary: Starved of food and light, corals can reduce their metabolism, lose biomass and maintain skeletogenesis; this strategy can be explained by the dynamics of structural and reserve biomass.
