Coral Reefs - Nature and rates of change

Climate change and Sea levels rise


Vulnerability of mangroves and tidal wetlands of the Great Barrier Reef to climate change.

Climate change, reefs and the Coral Triangle

Marine life spawns sooner as our oceans warm

Microborers may devour reefs in warmer, acidic oceans 

Coral polyps found to create cloud forming chemicals

Corals can protect themselves from rising sea temperatures: study finds

Coral more resilient than first thought, Australian scientists find

Researchers say Irukandji jellyfish migrating further south along Qld coast

Coral bleaching

Coral bleaching: the loss of colour from the living coral - can cause their death.

Study confirms nutrients increase the prevalence of both coral diseases and bleaching events.




Endangered species at risk include: native cowry, leafy sea-dragon, weedy sea-dragon, western blue devil, harlequin fish, and the striped pyjama squid.

Caulerpa taxiflora - a type of algae, destroys native seagrass in coastal habitats. This affects coral reefs because the seagrass filters out sediment that would otherwise go directly to the coral reef.

Disease

And then there were...none




10-20% of coral in Heron Island is already bleached.
