The Coral Sea: Physical environment, ecosystem status and biodiversity assets

The status of coral reefs in New Caledonia 2007.

National status report of coral reefs : New Caledonia.

Anthropogenic stressors. Interspecific competition and ENSO effects on a Mauritian coral reef

Towards multidisciplinary indicator dashboards for coral reef fisheries management

The diversity of reef ecosystems, the multiplicity of reef resource uses and the breadth of the range of the island socio-cultural contexts concerned make coral reef fisheries (CRF) management in the South Pacific a complex task. The health and state...

Released coral mucus does not enhance planktonic N-2 fixation rates

Dinitrogen (N-2) fixation by prokaryotic microorganisms provides bioavailable nitrogen in oligotrophic marine ecosystems such as coral reefs. The widespread though largely unknown heterotrophic diazotrophs require dissolved organic matter (DOM) for t...

Reef-building corals thrive within hot-acidified and deoxygenated waters

Coral reefs are deteriorating under climate change as oceans continue to warm and acidify and thermal anomalies grow in frequency and intensity. In vitro experiments are widely used to forecast reef-building coral health into the future, but often fa...

Enhancement of coral calcification via the interplay of nickel and urease

Corals are the main reef builders through the formation of calcium carbonate skeletons. In recent decades, coral calcification has however been impacted by many global (climate change) and local stressors (such as destructive fishing practices and ch...

Tracking trace elements into complex coral reef trophic networks

Humans and climate variability threaten large-bodied endemic fishes on coral reefs.
