Salinity tolerance, ontogeny of osmoregulation and zootechnical improvement in the larval rearing of the Caledonian Blue Shrimp, Litopenaeus stylirost...

The ontogeny of osmoregulationwas investigated in Litopenaeus stylirostris by studying salinity tolerance and osmoregulatory capacity. Shrimp at different larval and postlarval stages were exposed to various salinities and survival was monitored for ...

One new endemic plant species on average per month in New Caledonia, including eight more new species from ile Art (Belep Islands), a major micro-hots...

The New Caledonian biodiversity hotspot contains many micro-hotspots that exhibit high plant micro-endemism, and that are facing different types and intensities of threats. The Belep archipelago, and especially ile Art, with 24 and 21 respective narr...

Twenty years after Jaffre et al. (1998), is the system of protected areas now adequate in New Caledonia ?

Protected areas are the cornerstone on which conservation strategies are often built. Adapting systems of protected areas to rapid global changes is critical to meet the challenge of conservation in biodiversity hotspots. Twentyyears ago, Jaffre et a...

Infertile landscapes on an old oceanic island: the biodiversity hotspot of New Caledonia

The OCBIL theory comprises a set of hypotheses to comprehend the biota of old, climatically buffered, infertile landscapes (OCBILs). Here, we review evidence from the literature to evaluate the extent to which this theory could apply to the biodivers...

Garnierite characterization for open mineral databases

The nickel laterite mining industry faces lower recovery rates related to low ore grades, multiple nickel carrying minerals, as well as lateral and vertical heterogeneities at ore deposit scale. Garnierite, a complex mixture of nickel-bearing phyllos...

Garnierite characterisation for open data bases for nickel laterite exploration

The nickel laterite mining industry faces lower recovery rates related to low ore grades, multiple nickel carrying minerals, as well as lateral and vertical heterogeneities at ore deposit scale. Garnierite, a complex mixture of nickel-bearing phyllos...

Peridotite Weathering and Ni Redistribution in New Caledonian Laterite Profiles: Influence of Climate, Hydrology, and Structure

The peridotite massifs of New Caledonia are characterised by complex hydrodynamics influenced by intense inherited fracturing, uplift, and erosion. Following the formation of the erosion surfaces and alteration processes, these processes drive chemic...

Unexpected microbial diversity in new Caledonia's ultramafic ecosystems with conservation implications in a biodiversity hotspot

Soils harbour an incredible diversity of microorganisms that play crucial roles in ecosystem functioning. However, this biodiversity remains largely overlooked, with a poor understanding of how patterns form across landscapes. An eDNA metabarcoding a...

Soil organic matter decomposition in semi-arid mangrove stands (New Caledonia)

Organic matter (OM) dynamics in mangrove forests have been studied extensively in terms of the capacity of their soils to store organic carbon. While δ13C, δ15N, and C/N values for mangrove soils and sources are well reported, other indicators of O...

Campagne de surveillance de la population de Lacertoides pardalis (Scincidae) de la mine A1 - Commune du Mont-Dore (province Sud)

Le scinque-léopard de Nouvelle-Calédonie, Lacertoides pardalis, est une espèce spécialisée, inféodée à un type d'habitat particulier, possédant un spectre alimentaire original. En raison de son aire de distribution restreinte à ces quelque...
