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

The status of coral reefs in New Caledonia 2007.

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

Does habitat fragmentation restrict coral reef fish movements?

Résumé et présentation orale.

Effet de l'acidification des océans et de concentrations plus élevées en cobalt sur la croissance et l'efficacité photosynthétique de deux espèc...

Le but de cette étude était de déterminer les effets d’un enrichissement en cobalt combiné à une augmentation de la pCO2 sur la physiologie de deux espèces de coraux scléractiniaires de Calédonie, Stylophora pistillata et Acropora muric...

Monthly variability of self-recruitment for a coral reef damselfish

Understanding the dynamics of marine populations is critical to managing marine systems effectively and requires information on patterns of population dispersal and connectivity that are still poorly known. We used transgenerational marking to study ...

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...

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...

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...
