Un bilan plus détaillé pour une information plus complète Ce bilan, qui s'appuie sur l'analyse des informations relevées en 2018, décrit l'état des milieux terrestres, des eaux douces de surface et souterraines, ainsi que du milieu marin sur l...

Quel bilan pour l'environnement ?

Ce bilan a pour but de décrire l'état du milieu terrestre, des eaux douces de surface et souterraines, ainsi que du milieu marin. Il s'appuie sur l'analyse des informations relevées en 2020 sur les communes de Yaté, du Mont-Dore et de l'île des ...

Clay mineral evolution in the central Okinawa Trough since 28 ka: Implications for sediment provenance and paleoenvironmental change

The Okinawa Trough is a natural laboratory for the study of later Quaternary land-ocean interaction and paleoenvironmental changes. In this study we reconstruct the evolution of clay mineral assemblages in Core DGKS9604 retrieved from the central Oki...

Impact of plant root functional traits and associated mycorrhizas on the aggregate stability of a tropical Ferralsol

In many tropical regions, such as New Caledonia, soil erosion from anthropogenic activities and subsequent ecological restoration are major issues that require detailed soil and vegetation data for the production of management plans. To determine if ...

Does arbuscular and ectomycorrhizal fungal inoculation improve soil aggregate stability? A case study on three tropical species growing in ultramafic ...

In many tropical regions, soil erosion from anthropogenic activities and subsequent ecological restoration are major issues. Revegetation would be an efficient way to mitigate soil degradation. Some plant and mycorrhizal species are more useful than ...

Lagoon islets as indicators of recent environmental changes in the South Pacific – The New Caledonian example

The question of the impacts of climate change and sea level rise on small islands is currently much discussed. The many thousands of Pacific islands in their different contexts (geodynamic, climatic, etc.) and the insufficient data available explain ...
