“Respiration is essential in plants as energy is gained from sugars that are produced during photosynthesis, and as a by-product carbon dioxide is released” says PhD-student Lina. The amount of this plant respiration is essential to know when calculating uptake and release of carbon dioxide by living plants. Commonly, respiration by submerged plants is assumed to be the same in light and dark conditons. However, this assumption has to be reconsidered from now. “We found that respiration was lower during daylight hours which means, at this time, plants released less carbon dioxide back to the water” says Lina and continues that this will “be important when calculating how well marine habitats, such as sea grass meadows, work as carbon sinks”.

In conclusion, I have the feeling that Lina’s findings will affect the life of many marine biologists. Both for correcting, but also complicating their task of measuring marine primary production.

That’s good!
