Researchers show that seagrasses will benefit from increases in the temperature and CO2 in the oceans because their capacity to acquire nitrogen will be enhanced, not limiting their growth.
“In this study, we demonstrate that ocean warming increases the nitrogen demand of a globally distributed seagrass, Z. marina, and that this demand may be met by an increasing uptake of organic nitrogen”, reveals Ana Alexandre, a seagrass ecologist from the Centre of Marine Sciences (CCMAR) who led the research. The study now published in the prestigious journal Functional Ecology resulted from a collaboration between scientists from CCMAR and Bangor University and contains relevant conclusions about the effects of global change, and particularly ocean warming, on a marine organism.
The teams used an innovative approach that combined field observations of the rates of nitrogen acquisition by the seagrass in three sites along its latitudinal range (Iceland, United Kingdom and Portugal) with the species’ acquisition responses to temperature manipulation obtained from laboratory experiments.
