Coral reef food webs are highly vulnerable to species loss
To understand the functioning of ecosystems and their flows of matter and energy, it is essential to know the architecture of these ecosystems. This architecture consists of trophic interactions between organisms that determine the exchange of energy and nutrients within the system. For particularly rich ecological systems, such as coral reefs, our knowledge of the food web structure is still only partial. In the scientific literature, it was commonly accepted that most reef fishes were generalists.
