Coviability of social and ecological systems : reconnecting mankind to the biosphere in an era of global change. Vol. 2 : Coviability questioned by a ...

This second volume is the work of more than 55 authors from 15 different disciplines and includes complex systems science which studies the viability of components, and also the study of empirical situations. As readers will discover, the coviability...

Parameterizing the binding properties of dissolved organic matter with default values skews the prediction of copper solution speciation and ecotoxici...

Parameterizing speciation models by setting the percentage of dissolved organic matter (DOM) that is reactive (% r-DOM) toward metal cations at a single 65% default value is very common in predictive ecotoxicology. The authors tested this practice by...

[2019] Thio | La méthode

Comment lire ce bilan ? Pourquoi ce bilan ? En 2015, la commune de Thio et l'association Chavàà Xûâ devenaient membres de l'OEIL. À leur demande et celle de la province Sud, l'Observatoire a réalisé deux synthèses des connaissances environn...

High genetic differentiation and low connectivity in the coral Pocillopora damicornis type beta at different spatial scales in the Southwestern Indian...

Studying genetic connectivity in marine populations aims to understand the dispersal of an organism through the seascape and thus its gene flow. Here, we focused on one lineage of the recently revised coral Pocillopora damicornis complex, P. damicorn...

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 ...

Hydrodynamic time parameters response to meteorological and physical forcings : toward a stagnation risk assessment device in coastal areas

Identifying zones of stagnation and deposition of terrigenous matter or contaminants induced by human activity is a key issue in coastal areas. In this paper, circulation processes and potential contaminant stagnation and deposition zones were assess...

Integration and segregation in the evolution of agricultural development policies in New Caledonia

Relationships between agriculture and rural societies raise controversies that question development models. Dichotomous views dominate the debate: small and large structures, inclusive or exclusive of agriculture, etc. This paper identifies how conce...

The metamorphic sole of New Caledonia ophiolite: Ar-40/Ar-39, U-Pb, and geochemical evidence for subduction inception at a spreading ridge

Amphibolite lenses that locally crop out below the serpentinite sole at the base of the ophiolite of New Caledonia (termed Peridotite Nappe) recrystallized in the high-temperature amphibolite facies and thus sharply contrast with blueschists and eclo...

Respective and combined roles of rhizobia and ectomycorrhizal fungi in the plant growth, symbiotic efficiency, nutrients and metals contents of a legu...

Acacia spirorbis subsp. spirorbis Labill. is a widespread tree legume in New Caledonia that establishes mutual symbioses with both N2-fixing rhizobia and ectomycorrhizal (ECM) fungi. Moreover, A. spirorbis is able to naturally grow on ultramafic soil...

Architectural traits underlie growth form diversity and polycarpic versus monocarpic life histories in Cerberiopsis (Apocynaceae)

Plant architecture strongly influences plant growth habits, as it determines the arrangement, function and fate of meristems. How architecture could be involved in the monocarpic life history, i.e. dying after flowering, remains poorly investigated. ...
