Impact of environmental changes on Oculina patagonica coral holobiont
Los corales son metazoos del phylum Cnidaria que se consideran el producto de una interaccion mutualista entre el coral y algas unicelulares simbioticas del genero Symbiodinium conocidas comoExpand
Finding of 132, 173‐cyclopheophorbide a enol as a degradation product of chlorophyll in shrunk zooxanthellae of the coral Montipora digitata
The formation of cPPB‐aE in shrunken zooxanthellae is considered to be a mechanism for avoiding oxidative stress and suggests that the chls have been degraded to cPPBs, a compound that is not fluorescent, which precludes the formation of reactive oxygen species. Expand
Increased seawater temperature increases the abundance and alters the structure of natural Vibrio populations associated with the coral Pocillopora damicornis
Rising seawater temperature associated with global climate change is a significant threat to coral health and is linked to increasing coral disease and pathogen-related bleaching events. We performedExpand
Localized bleaching in Hawaii causes tissue loss and a reduction in the number of gametes in Porites compressa
The observed localized bleaching results in both partial colony mortality and a reduced number of gametes and was termed Porites Bleaching with Tissue Loss (PBTL), and investigated the whole-colony effects by following disease progression through time and examining the effect of localizedBleaching on coral fecundity.

Coral disease pathogens of the Indo-Pacific Ocean
The classification of these two syndromes as separate coral diseases be postponed until further evidence is collected, and all six pathogens identified were members of the γ-Proteobacteria family Vibrionacae, each with greater than 98% sequence identity with the previously characterized coral bleaching pathogen Vibrio coralliilyticus.

Impacts of climate change on Australian marine life: part C : literature review
The illuminated zone of coastal and oceanic waters is inhabited by a great diversity of tiny, usually single-celled, microscopic algae known as phytoplankton, which utilise sun light, water, and dissolved CO2 and nutrients to grow and reproduce. Expand
Disease and immunity in Caribbean and Indo-Pacific zooxanthellate corals
Etiologies of only 5 of the 18 coral diseases have been determined through fulfillment of Koch's postulates, and alternative techniques for identifying disease-causing organisms are described. Expand
The coral probiotic hypothesis.
The Coral Probiotic Hypothesis posits that a dynamic relationship exists between symbiotic microorganisms and environmental conditions which brings about the selection of the most advantageous coral holobiont. Expand
The role of microorganisms in coral bleaching
Evidence is discussed for an alternative but not mutually exclusive concept, the microbial hypothesis of coral bleaching, which is that high water temperatures cause irreversible damage to the symbiotic algae resulting in loss of pigment and/or algae from the holobiont. Expand
A role for bacterial experimental evolution in coral bleaching mitigation?
This work provides a workflow on how to experimentally evolve coral-associated bacteria to confer thermal tolerance to coral hosts and emphasizes the value of implementing this approach in coral reef conservation and restoration efforts. Expand


Ultraviolet radiation and coral bleaching
Results of a field experiment are reported showing that, irrespective of high water temperatures, short-term increases in ultraviolet radiation of a magnitude possible under calm, clear water column conditions can readily induce bleaching in reef-building corals. Expand
Coral reef bleaching in the 1980s and possible connections with global warming.

  • Trends in ecology & evolution
  • 1991
Recent bleaching events and their possible link with sea warming and other environmental stresses are described, and some speculation on the fate of coral reefs if the Earth enters a sustained period of warming is offered. Expand
