Spatial patterns and short-term changes of coral assemblages along a cross-shelf gradient in the southwestern lagoon of New Caledonia

Coral reef assemblages generally form gradients of spatial structures which are governed by a variety of interacting physical and biological processes that vary in intensity, frequency, and spatial scale. Assessing the structure of contemporary reef ...

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 ...

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

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)

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

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).

Limpus C.J.. Migrations of green turtles (Chelonia mydas) between nesting and foraging grounds across the Coral Sea.
