Summary: Increasing awareness of marine pollution has increased the impetus to develop procedures that reduce damage to coastal habitats, whilst allowing ecologically sustainable development. Macroalgae are ecologically and commercially important habitats, however little is known of their physiological responses to pollution, despite the fact that chemicals found in coastal waters can directly interfere with photosynthesis. This project will assess sub-lethal stress responses of photsynthesis in macroalgae, and develop a test using the photsynthetic capacity by chlorophyll fluorescence. This project addresses one of MAFRI's core objectives to develop methods to assess sub-lethal recovery of marine habitats, and to give a better conceptual understanding of the impacts of pollutants on these habitats.
