Temperature amplifies the effect of high CO 2 on the photosynthesis, respiration, and calcification of the coralline algae Phymatolithon lusitanicum
Abstract The combination of ocean acidification (OA) and global warming is expected to have a significant effect on the diversity and functioning of marine ecosystems, particularly on calcifying algae such as rhodoliths (maërl) that form extensive beds worldwide, from polar to tropical regions.
