Ocean acidification locks algal communities in a species‐poor early successional stage
Abstract Long‐term exposure to CO 2 ‐enriched waters can considerably alter marine biological community development, often resulting in simplified systems dominated by turf algae that possess reduced biodiversity and low ecological complexity. Current understanding of the underlying processes by whi...

Abstract Long‐term exposure to CO 2 ‐enriched waters can considerably alter marine biological community development, often resulting in simplified systems dominated by turf algae that possess reduced biodiversity and low ecological complexity. Current understanding of the underlying processes by which ocean acidification alters biological community development and stability remains limited, making the management of such shifts problematic. Here, we deployed recruitment tiles in reference (pH T 8.137 ± 0.056 SD) and CO 2 ‐enriched conditions (pH T 7.788 ± 0.105 SD) at a volcanic CO 2 seep in Japan to assess the underlying processes and patterns of algal community development.
