Life history of the silverside Atherinomorus lacunosus (Atherinidae) in New Caledonia

The abundance, the seasonal variation and the life history of the silverside, #Atherinomorus lacunosus$, are studied from fish caught in the lagoons around New Caledonia. About 270 nights of fishing were carried out between 1980 and 1983. The silvers...

Remote High-Definition Rotating Video Enables Fast Spatial Survey of Marine Underwater Macrofauna and Habitats

Observing spatial and temporal variations of marine biodiversity from non-destructive techniques is central for understanding ecosystem resilience, and for monitoring and assessing conservation strategies, e.g. Marine Protected Areas. Observations ar...

Social segregation of humpback whales in contrasted coastal and oceanic breeding habitats

Maternal habitat preferences of humpback whales (Megaptera novaeangliae) are well documented from decades of coastal research but oceanic areas have received less attention. Whales breeding in New Caledonia occupy both ecosystems: a coastal reef comp...

Benthic pelagic coupling in a shallow oligotrophic ecosystem : Importance of microphytobenthos and physical forcing

In coral reef lagoons, microphytobenthos (MPB) primary production can be of the same order of magnitude as coral or macroalgal production. As they are situated in oligotrophic waters, sediments receive low amount of allochtonous nutrients, and their ...

Spatial distribution of microbial communities in the shallow submarine alkaline hydrothermal field of the Prony bay, New Caledonia

The shallow submarine hydrothermal field of the Prony Bay (New Caledonia) discharges hydrogen- and methane-rich fluids with low salinity, temperature (< 40°C) and high pH (11) produced by the serpentinization reactions of the ultramafic baseme...

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...
