Coral Bleaching Susceptibility Is Predictive of Subsequent Mortality Within but Not Between Coral Species

open access: yesFrontiers in Ecology and Evolution, 2020
Marine heat waves instigated by anthropogenic climate change are causing increasingly frequent and severe coral bleaching events that often lead to widespread coral mortality.

An enigmatic decoupling between heat stress and coral bleaching on the Great Barrier Reef [PDF]

open access: yesPeerJ, 2019
Ocean warming threatens the functioning of coral reef ecosystems by inducing mass coral bleaching and mortality events. The link between temperature and coral bleaching is now well-established based on observations that mass bleaching events usually ...

The influence of extreme climate events on models of coral colony recruitment and survival in the Caribbean [PDF]

open access: yes, 2012
Knowledge of coral recruitment patterns helps us understand how reefs react following major disturbances and provides us with an early warning system for predicting future reef health problems.

Combination Analysis of Metatranscriptome and Metagenome Reveal the Composition and Functional Response of Coral Symbionts to Bleaching During an El Niño Event

open access: yesFrontiers in Microbiology, 2020
With the abnormal rise in ocean temperatures globally in recent years, coral bleaching is becoming common and serious. However, the response mechanisms and processes of coral symbionts to bleaching are not well understood. In this study, metagenomics and

Decolouring bloodmeal: Consumption and potential recycling of peracetic acid [PDF]

open access: yes, 2012
A method of deodorizing and decolouring bloodmeal using an equilibrium mixture of peracetic acid, hydrogen peroxide, acetic acid and water has been developed to improve its marketability as a source of protein for bioplastics.
