Trophic cascade facilitates coral recruitment in a marine reserve

Proceedings of the National Academy of Sciences, Journal Year: 2007, Volume and Issue: 104(20), P. 8362 - 8367

Reduced fishing pressure and weak predator–prey interactions within marine reserves can create trophic cascades that increase the number of grazing fishes reduce coverage macroalgae on coral reefs. Here, we show impacts extend beyond enhance process recruitment. Increased fish grazing, primarily driven by reduced fishing, was strongly negatively correlated with macroalgal cover resulted in a 2-fold density recruits Bahamian reef system. Our conclusions are robust because four alternative hypotheses may generate spurious correlation between recruitment were tested rejected. Grazing appears to influence community structure recruits, but no detectable found overall size-frequency distribution, structure, or corals. We interpret this absence pattern adult as symptomatic impact recent disturbance event masks recovery trajectories individual Marine not panacea for conservation facilitate corals from help sustain biodiversity organisms depend complex three-dimensional habitat.

Global patterns in the impact of marine herbivores on benthic primary producers

Ecology Letters, Journal Year: 2012, Volume and Issue: 15(8), P. 912 - 922

Abstract Despite the importance of consumers in structuring communities, and widespread assumption that consumption is strongest at low latitudes, empirical tests for global scale patterns magnitude consumer impacts are limited. In marine systems, long tradition experimentally excluding herbivores their natural environments allows to be quantified on scales using consistent methodology. We present a quantitative synthesis 613 herbivore exclusion experiments test influence traits, producer traits environment strength benthic producers. Across globe, profoundly reduced abundance (by 68% average), with effects rocky intertidal habitats weakest dominated by vascular plants. Unexpectedly, we found little or no latitude mean annual water temperature. Instead, differed most consistently among taxonomic morphological groups. Our results show grazing plant better predicted than large‐scale variation habitat temperature, there previously unrecognised degree phylogenetic conservatism susceptibility consumption.

New perspectives on ecological mechanisms affecting coral recruitment on reefs

Smithsonian contributions to the marine sciences, Journal Year: 2009, Volume and Issue: 38, P. 437 - 457

Published: Jan. 1, 2009

Coral mortality has increased in recent decades, making coral recruitment more important than ever sustaining reef ecosystems and contributing to their resilience.This review summarizes existing information on ecological factors affecting scleractinian recruitment.Successful requires the survival of offspring through sequential life history stages.Larval availability, successful settlement, post-settlement growth are all necessary for addition new individuals a ultimately maintenance or recovery ecosystems.As environmental conditions continue become hostile corals global scale, further research fertilization ecology, connectivity, larval condition, positive negative cues infl uencing substrate selection, ecology will be critical our ability manage these diverse recovery.A better understanding is fundamental management.
