An exclusion experiment to study the influence of habitat structure provided by Mussismilia corals (Cnidaria; Anthozoa) on the predation of associated crustaceans
Abstract Predation is an interaction between species that influences community organisation by the direct consumption of prey, influencing prey numbers, behaviours and traits. The intensity of predation is greatly influenced by the environment, and the physical structure of habitats may influence pr...
