Evidence of nickel (Ni) efflux in Ni-tolerant ectomycorhizal Pisolithus albus isolated from ultramafic soil

Nickel (Ni)-tolerant ectomycorrhizal Pisolithus albus was isolated from extreme ultramafic soils that are naturally rich in heavy metals. This study aimed to identify the specific molecular mechanisms associated with the response of P. albus to nicke...

Waterborne nickel bioaccumulation in Gammarus pulex: Comparison of mechanistic models and influence of water cationic composition

The biodynamic and saturation models offer promising lines of enquiry to predict the bioaccumulation of metals by aquatic organisms. However, in order to construct these models, the accumulation strategies have to be defined for each metal/organism c...

Supergene nickel ore deposits controlled by gravity-driven faulting and slope failure (Peridotite Nappe, New Caledonia)

New Caledonia holds one of the largest supergene nickel ore deposits worldwide. Two main ore types are recognized: oxide and hydrous Mg-Ni silicate types. Our study focuses on the latter type, usually located in elevated parts of the Peridotite Nappe...
