Atelier marin, vers un suivi optimal des lagons et récifs Suivi de la mangrove sous forçages climatiques et anthropiques

Points abordés :
- Rôle de la mangrove dans la conservation des littoraux tropicaux,
- les menaces qui pèsent sur cet écosystème,
- la biodiversité des mangroves en Nouvelle-Calédonie,
- Devenir des effluents de la ...

Typologies et biodiversité des mangroves de Nouvelle Calédonie

Évaluation de la biodiversité des mangroves et influence des facteurs biogéographiques sur la répartition des palétuviers. Interaction entre les palétuviers et leur substrats Développement méthodologique pour la cartographie des mangroves à ...

Meiofauna distribution in a mangrove forest exposed to shrimp farm effluents (New Caledonia)

Meiofauna abundance, biomass and individual size were studied in mangrove sediments subjected to shrimp farm effluents in New Caledonia. Two strategies were developed: i) meiofauna examination during the active (AP) and the non-active (NAP) periods o...

Typologies et biodiversité des mangroves de Nouvelle Calédonie - Rapport intermédiaire: Approche par télédétection

Récapitulatif des différentes méthodes utilisées pour la classification des mangroves par télédétection.

Influence of mangrove zonation on CO2 fluxes at the sediment-air interface (New Caledonia)

Mangroves are the major ecosystems of tropical and subtropical coastlines. They are considered as a sink for atmospheric CO2 because they are characterized both by high net primary production, and by low rates of organic matter decomposition. However...

Temporal variability of CO2 fluxes at the sediment-air interface in mangroves (New Caledonia)

Carbon budgets in mangrove forests are uncertain mainly due to the lack of data concerning carbon export in dissolved and gaseous forms. Temporal variability of in situ CO2 fluxes was investigated at the sediment-air interface in different seasons in...

Superficie en Nouvelle-Calédonie : 359 km² Superficie en province Sud : 163 km² Côte ouest : 88 % des mangroves Nombre d'espèces : 190 dont 10% endémiques Une zone tampon entre terre et mer, un intérêt écologique majeur La mangrove joue pl...

Net ecosystem CO2 exchange in the "Coeur de Voh" mangrove, New Caledonia : effects of water stress on mangrove productivity in a semi-arid climate

In New Caledonia, a world-renowned mangrove, the "Coeur de Voh", grows in a semi-arid climate and at a high elevation in the intertidal zone. Net CO2 exchange (NEE) between the Avicennia marina shrub mangrove and the atmosphere was studied using an e...

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...
