High CO₂ enhances the competitive strength of seaweeds over corals

Ecology Letters (2011) 14: 156–162 Abstract Space competition between corals and seaweeds is an important ecological process underlying coral‐reef dynamics. Processes promoting seaweed growth survival, such as herbivore overfishing eutrophication, can lead to local reef degradation. Here, we present the case that increasing concentrations of atmospheric CO 2 may be additional driving a shift from on reefs. Coral ( Acropora intermedia ) mortality in contact with common Lobophora papenfussii increased two‐ threefold background (400 ppm) highest level projected for late 21st century (1140 ppm). The strong interaction coral was most likely attributable chemical competitive mechanism, control algal mimics showed no mortality. Our results suggest reefs become increasingly susceptible proliferation under ocean acidification, processes regulating abundance (e.g. herbivory) will play role maintaining abundance.

The biodiversity of coral reefs is dominated by invertebrates. Many these invertebrates live in close association with scleractinian corals, relying on corals for food, habitat or settlement cues. Given their strong dependence it great concern that our knowledge coralassociated so limited, especially light severe and ongoing degradation reef habitats the potential species extinctions. This review examines taxonomic extent coral-associated invertebrates, levels hosts, nature associations between factors threaten now future.
