Investigating the March 28th 1875 and the September 20th 1920 earthquakes/tsunamis of the Southern Vanuatu arc, offshore Loyalty Islands, New Caledoni...

New Caledonia's Loyalty Islands are located in the southwest region of the Pacific ocean in the highly seismogenic southern Vanuatu subduction zone and therefore may be subject to devastating local tsunamis. Over the past 150 years, two large tsunami...

Colonization and release processes of viruses and prokaryotes on artificial marine macroaggregates

Marine organic aggregates are sites of high of viral accumulation; however, still little is known about their colonization processes and interactions with their local bacterial hosts. By taking advantage of a novel approach (paramagnetic functionaliz...

Cryptic adaptive radiation in tropical forest trees in New Caledonia

The causes of the species richness of tropical trees are poorly understood, in particular the roles of ecological factors such as soil composition. The nickel(Ni)-hyperaccumulating tree genus Geissois (Cunoniaceae) from the South-west Pacific was cho...

Physiological response of the blue shrimp Litopenaeus stylirostris to short-term confinement on a pond bottom

The blue shrimp Litopenaeus stylirostris was exposed to pond sediment for 48 h and its physiological response was studied in relation to molt stage. Shrimp were maintained in cages within a semi-intensive pond after 4 months of rearing. Hypoosmoregul...

Floating cages as an experimental tool for shrimp culture studies: first attempts to check their reliability

The first aim of this study was to evaluate on a technical basis the rearing of shrimps in floating cages set up in earthen ponds. Shrimps reared in and outside the cages presented comparable growths and survival rates. Then it was concluded that shr...

Sequence polymorphism-based identification and quantification of Vibrio nigripulchritudo at the species and subspecies level targeting an emerging pat...

In a previous study, we demonstrated the existence of an emerging cluster of Vibrio nigripulchritudo that proved to be associated with shrimp mortality events in New Caledonia. Using sequence polymorphisms evidenced in this previous MultiLocus Sequen...

On the Influence and Correction of Water Content on pXRF Analysis of Lateritic Nickel Ore Deposits in the Context of Open Pit Mines of New-Caledonia

In a number of applications, the use of portable X-ray fluorescence (pXRF) instruments offers a time and cost-saving alternative to standard laboratory instruments. This is particularly true in a mining context where decisions must be taken quickly i...

restoptr: An R package for ecological restoration planning

Ecological restoration is essential to curb the decline of biodiversity and ecosystems worldwide. Since the resources available for restoration are limited, restoration efforts must be cost-effective to achieve conservation outcomes. Although decisio...
