Assessing threats from coral and crustose coralline algae disease on the reefs of New Caledonia

The present study reports the results of the first quantitative survey of lesions on coral and crustose coralline algae (CCA) on reefs in the lagoon of New Caledonia. Surveys on inshore and offshore reefs were conducted at 13 sites in 2010, with 12 s...

What revegetation method will restore the biodiversity of old mine sites in New Caledonia;Deuxième conférence internationale sur l'écologie des mil...

New Caledonia is renowned for its floristic diversity and high level of endemism. Outcrops of ultramafic rock, the origin of nickel ore, cover 1/3 of the Grand Terre (main island) and possess a highly diverse flora (1800 species of phanerogams of whi...

First and repeated records of the tropical-temperate crab Asthenognathus atlanticus Monod, 1932 (Decapoda: Brachyura) in the eastern part of the Bay o...

Asthenognathus atlanticus Monod, 1932, has been reported for the first time from the eastern part of the Bay of Seine (eastern English Channel). A total of 30 specimens were collected between the years 2008 and 2011, along the Normandy coast from Oui...

Reef-building corals thrive within hot-acidified and deoxygenated waters

Coral reefs are deteriorating under climate change as oceans continue to warm and acidify and thermal anomalies grow in frequency and intensity. In vitro experiments are widely used to forecast reef-building coral health into the future, but often fa...

Differential weathering in ultramafic rocks of New Caledonia : the role of infiltration instability

Ultramafic rocks of New Caledonia present extensive pseudokarstic features: undulations of the base of the weathering profile, fractures enlarged by dissolution, dolines. Possible influence of the infiltrative instability on differential weathering o...

Spatial patterns and short-term changes of coral assemblages along a cross-shelf gradient in the southwestern lagoon of New Caledonia

Coral reef assemblages generally form gradients of spatial structures which are governed by a variety of interacting physical and biological processes that vary in intensity, frequency, and spatial scale. Assessing the structure of contemporary reef ...

Tropical plant communities modifiy soil aggregate stability along a successional vegetation gradient on a Ferralsol

Soil aggregate stability is viewed as a promising indicator of the restoration status in eroded ecosystems, where the change in plant community composition through successional dynamics is a key driver of ecosystem restoration. In many tropical regio...

Assessment method of the sea turtle-nesting habitat of small reef islands

The coral islets in the lagoon of New Caledonia are a major breeding and nesting site for various species. Many species reproduce and nest there, whether they are Chelonians (green turtles and loggerhead turtles), ofshore seabirds (Procellariidae: sh...
