Dissolved organic matter influences N-2 fixation in the New Caledonian lagoon (Western Tropical South Pacific)

Specialized prokaryotes performing biological dinitrogen (N-2) fixation ("diazotrophs") provide an important source of fixed nitrogen in oligotrophic marine ecosystems such as tropical and subtropical oceans. In these waters, cyanobacterial photosynt...

Soil and Aboveground Carbon Stocks in a Planted Tropical Mangrove Forest (Can Gio, Vietnam)

Can Gio mangrove is the largest mangrove forest in Vietnam, covering approximately 35,000 hectares. This forest was partially destroyed during the war, and restored between the late 1970s and the early 1990s. Currently, the Can Gio mangrove forest re...

Nickel mass balance and isotopic records in a serpentinic weathering profile: Implications on the continental Ni budget

During serpentinite rock weathering, Ni is concentrated in the regolith owing to residual and secondary enrichment, forming a Ni-rich deposit under tropical conditions. This study presents geochemical, isotopic, and mineralogical data for Ni from the...

Influence of species and stand position on isotopic and molecular composition of leaf litter during degradation in an urban mangrove forest

Understanding the diagenetic processes of organic matter (OM) within mangrove forests is essential to grasp ecosystem dynamics and exchanges with adjacent ecosystems. This study investigated the influence of urban runoff on leaf litter degradation in...

Heating effect on chromium speciation and mobility in Cr-rich soils: A snapshot from New Caledonia

In the context of global warming, wildfires are expected to increase in both frequency and intensity in the forthcoming decades. Among the environmental and ecological wildfires-induced impacts, the risk of freshwater pollution by soilborne trace met...

Constraint-based systematic conservation planning, a generic and expressive approach : application to decision support in the conservation of New Cale...

In the context of the global biodiversity crisis, human activities are the principal cause of natural habitat degradation, fragmentation, and destruction. Globally, the species extinction rate has reached an unprecedented level in human history and a...
