English term or phrase:take over
Grazing of algae is important because if macroalgae (seaweeds) become dominant, they can occupy most of the available space on the reef and prevent settlement of corals and other invertebrates. Normally there is a balance, with macroalgal biomass held in check by grazers, which by their feeding continuously create small patches of bare substrate where invertebrates can settle. However, in the absence of sufficient grazing, macroalgae (which when well-grown may be unpalatable to most herbivores) can ///take over///. When this happens you can get a dramatic shift to an alternative, macroalgal dominated, ecosystem state.
