Ocean warming and acidification modify top-down and bottom-up control in a tropical seagrass ecosystem

Abstract Seagrass ecosystem is one of the most productive ecosystems in coastal waters providing numerous ecological functions and supporting a large biodiversity. However, various anthropogenic stressors including climate change are impacting these vulnerable habitats. Here, we investigated the ind...
