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...

Innate Immune Responses of a Scleractinian Coral to Vibriosis

Scleractinian corals are the most basal eumetazoan taxon and provide the biological and physical framework for coral reefs, which are among the most diverse of all ecosystems. Over the past three decades and coincident with climate change, these phot...

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...

Seabirds supply nitrogen to reefbuilding corals on remote Pacific islets

Seabirds concentrate nutrients from large marine areas on their nesting islands playing an important ecological role in nutrient transfer between marine and terrestrial ecosystems. Here we investigate the role of guano on corals reefs across scales b...

Artificial coral reefs, electrochemistry and calcium carbonate: electrodeposited coral-like aragonite

Modeling and computational tools for coral reef management and conservation.

Evidence for mitigation of coral bleaching by manganese

Unprecedented mass coral bleaching events due to global warming and overall seawater pollution have been observed worldwide over the last decades. Although metals are often considered as toxic substances for corals, some are essential at nanomolar co...

Gravity of human impacts mediates coral reef conservation gains

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