SUMMARY:

In reef systems, high diversity propitiates different ecological interactions. Coral, algae, and herbivores live in these systems and interact with each other with benefits, injuries, or neutral effects, and they are responsible for reef functioning. Herbivores are the main consumer of algae, and in most times, of corals, and they can regulate these interactions and, also, being regulated by coral-algal interactions. Here we explore the interactions between coral, algae, and herbivores under different perspectives. In a systematic review in a global scale (Chapter 1), studies at Pacific and Caribben and North Atlantic stand out, highlighting massive and branching corals interacting with macroalgae and turf algae. Coral larvae are mainly benefited from algae, while adults are injured, and the influence of herbivores and the effects of global changes vary. Focusing on Brazilian reefs, we identified the main coral and algal species, their interactions and effects (Chapter 2). We also evaluate the effects of local impacts and tested the impacts of iron from dam failures on algal palatability for herbivores. We found that amphipods and sea urchins consume more algal biomass in the middle exposure time, while for fish the result is the opposite (Chapter 3). In lab, we simulated the current and future conditions of temperature to understand the effects of climate change on coral-algal interactions (Chapter 4). We also simulate the effects of temperature on algal consume by herbivores, and we found that palatability varies among herbivores (Chapter 5). Integrating these perspectives, we intend to contribute with knowledge about coral-algal-herbivore interactions and their responses to local and global impacts, allowing connect reef function with ecosystem services from reefs.
