Molecular, quantitative and abiotic variables for the delineation of evolutionary significant units : case of sandalwood (Santalum austrocaledonicum V...

Various approaches have been developed to define conservation units for plant and animal species. In this study we combined nuclear microsatellites (from a previous published study) and chloroplast microsatellites (assessed in the present study), lea...

Reconstruction of local sea levels at South West Pacific Islands : a multiple linear regression approach (1988-2014)

Rising sea levels are a critical concern in small island nations. The problem is especially serious in the western south Pacific, where the total sea level rise over the last 60 years has been up to 3 times the global average. In this study, we aim a...

Differential weathering in ultramafic rocks of New Caledonia : the role of infiltration instability

Ultramafic rocks of New Caledonia present extensive pseudokarstic features: undulations of the base of the weathering profile, fractures enlarged by dissolution, dolines. Possible influence of the infiltrative instability on differential weathering o...

Linkages between root traits, soil fungi and aggregate stability in tropical plant communities along a successional vegetation gradient

Aims : Determining which abiotic and biotic factors influence soil aggregate stability (MWD) in tropical climates is often confounded by soil type. We aimed to better understand the influence of soil physical and chemical components, vegetation and f...

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...

Fracture controlled permeability of ultramafic basement aquifers : inferences from the Koniambo massif, New Caledonia

We study the relationship between fracture distribution and permeability in weathered peridotites exposed to tropical climate using the data from the Koniambo massif (New Caledonia, South Pacific). The vertical distribution of hydraulic conductivity ...

Genetic diversity and phylogeny of Aedes aegypti, the main arbovirus vector in the Pacific

Background The Pacific region is an area unique in the world, composed of thousands of islands with differing climates and environments. The spreading and establishment of the mosquito Aedes aegypti in these islands might be linked to human migration...
