Diurnal temporal patterns of the diversity and the abundance of reef fishes in a branching coral patch in New Caledonia

Small-scale spatial and temporal variability in animal abundance is an intrinsic characteristic of marine ecosystems but remains largely unknown for most animals, including coral reef fishes. In this study, we used a remote autonomous unbaited video ...

Ephemeral and localized outbreaks of the coral predator Acanthaster cf. solaris in the southwestern lagoon of New Caledonia

Outbreaks of the coral predator Acanthaster spp., the crown-of-thorns seastar (COTS), cause major coral declines across the Indo-Pacific. However, the processes surrounding the initiation and propagation of COTS outbreaks are still unclear. We observ...

Major sources of organic matter in a complex coral reef lagoon: Identification from isotopic signatures (?13C and ?15N).

Distributions and abundances of sublineages of the N-2-fixing cyanobacterium Candidatus Atelocyanobacterium thalassa (UCYN-A) in the New Caledonian co...

Nitrogen (N-2) fixation is a major source of nitrogen that supports primary production in the vast oligotrophic areas of the world's oceans. The Western Tropical South Pacific has recently been identified as a hotspot for N-2 fixation. In the Noumea ...

Application of the support vector regression method for turbidity assessment with MODIS on a shallow coral reef lagoon (Voh-Kone-Pouembout, New Caledo...

Particle transport by erosion from ultramafic lands in pristine tropical lagoons is a crucial problem, especially for the benthic and pelagic biodiversity associated with coral reefs. Satellite imagery is useful for assessing particle transport from ...

Major Sources of Organic Matter in a Complex Coral Reef Lagoon: Identification from Isotopic Signatures (?13C and ?15N)

The same but different: stable isotopes reveal two distinguishable, yet similar, neighbouring food chains in a coral reef

Diurnal temporal patterns of the diversity and the abundance of reef fishes in a branching coral patch in New Caledonia.

The use of a bi-metallic structure under cathodic protection in saewater favors a 3D calcareous growth imitating the coral structure
