Impact of Herbivore Identity on Algal Succession and Coral Growth on a Caribbean Reef

PLoS ONE, Journal Year: 2010, Volume and Issue: 5(1), P. e8963 - e8963

Background Herbivory is an important top-down force on coral reefs that regulates macroalgal abundance, mediates competitive interactions between macroalgae and corals, provides resilience following disturbances such as hurricanes bleaching. However, reductions in herbivore diversity abundance via disease or over-fishing may harm corals directly indirectly increase susceptibility to other disturbances. Methodology Principal Findings In two experiments over years, we enclosed equivalent densities masses of either single-species mixed-species herbivorous fishes replicate, 4 m2 cages at a depth 17 m reef the Florida Keys, USA evaluate effects identity species richness colonization development communities cascading algae growth. Year 1, used redband parrotfish (Sparisoma aurofrenatum) ocean surgeonfish (Acanthurus bahianus); 2, princess (Scarus taeniopterus). On new substrates, rapid grazing by kept early successional stage dominated short, filamentous crustose coralline did not suppress contrast, feeding allowed accumulation tall filaments later suppressed These patterns contrast with from established undergoing primary succession; substrates significantly reduced upright cover while significant increases late macroalgae. Significance This study further highlights importance biodiversity affecting ecosystem function different had very impacts depending developmental community. The species-specific suggest species-rich fauna can be critical providing need for recovery common bleaching storm damage.

High CO₂ enhances the competitive strength of seaweeds over corals

Ecology Letters, Journal Year: 2010, Volume and Issue: 14(2), P. 156 - 162

Published: Dec. 14, 2010

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.
