Many transitioning away from scleractinian-coral-dominated communities composed primarily non-scleractinian taxa. This study evaluated recovery patterns reef following associated with Niño. We examined temporal trends among 5 most spatially abundant taxa stony coral species 1999 2009 at 3 spatial scales, applied a Principal Coordinate Analysis (PCoA) determine whether their cover resulted shift community structure. Trends decreasing were not identified Keys-wide between 2009, but 2 habitats examined—shallow deep forereefs—did show significant decline cover. Concomitantly, octocoral significantly increased all habitats. The transition octocorals was evident shallow forereefs, where 9 12 overwhelmingly influenced PCoA. On sponge did increase, impart clearly defined structure like observed forereefs. Community composition patch relatively consistent during study, increase may accelerate further cold-water event 2010. These results demonstrate emerging as predominant Keys. Although have started long ago, apparent resilience present-day stressors will likely allow this continue into foreseeable future.

Algal contact as a trigger for coral disease

Ecology Letters, Год журнала: 2004, Номер 7(10), С. 919 - 923

Abstract Diseases are causing alarming declines in reef‐building coral species, the foundation blocks of reefs. The emergence these diseases has occurred simultaneously with large increases abundance benthic macroalgae. Here, we show that physical contact macroalga Halimeda opuntia can trigger a virulent disease known as white plague type II caused widespread mortality most Caribbean species. Colonies dominant Montastraea faveolata exposed to algal transplants developed whereas unexposed colonies did not. bacterium Aurantimonas coralicida , causative agent disease, was present on H. sampled close to, and away from diseased corals, indicating alga serves reservoir for this pathogen. Our results suggest spread macroalgae reefs could account elevated incidence over past decades reduction macroalgal help control epizootics.

The role poor water quality this decline is particularly unclear, with most previous studies providing only weak correlations between nutrient mortality. Here we experimentally show that routinely measured components (nitrate, phosphate, ammonia) do not cause substantial In contrast, dissolved (DOC), which rarely on reefs, does. Elevated DOC also accelerate growth rate microbes living corals' surface mucopolysaccharide layer by an order magnitude, suggesting occurs due disruption balance its associated microbiota. We propose model Caribbean shift further from macroalgal dominance. Increasing should be recognized as threat monitored.

Translating ecosystem indicators into decision criteria

ICES Journal of Marine Science, Год журнала: 2005, Номер 62(3), С. 569 - 576

Abstract Defining and attaining suitable management goals probably represent the most difficult part of ecosystem-based fisheries management. To achieve those we ultimately need to define ecosystem overfishing in a way that is analogous concept used single-species Ecosystem-based control rules can then be formulated when various indicators are evaluated with respect fishing-induced changes. However, these multi-attribute will less straightforward than applied typically management, may gradient rather binary decision criteria. Some criteria suggested, based on empirically derived from Georges Bank, Gulf Maine ecosystem. Further development translation into one major areas for progress science
