Circulation and suspended sediment transport in a coral reef lagoon: The south-west lagoon of New Caledonia

The south-west lagoon of New Caledonia is a wide semi-open coral reef lagoon bounded by an intertidal barrier reef and bisected by numerous deep inlets. This paper synthesizes findings from the 2000-2008 French National Program EC2CO-PNEC relative to...

Interpretation of kelvin rossby waves in the equatorial pacific from model-geosat data intercomparison during the 1986-1987 el-nino

Analysis of Geosat sea level data over the period November 1986-November 1987 has evidenced long, low-frequency equatorial wave propagations over most of the equatorial Pacific basin (Delcroix et al.,1991). The succession of downwelling Kelvin, upwel...

Comparison of visual census and high definition video transects for monitoring coral reef fish assemblages

Monitoring fish and underwater habitats, particularly in and around marine protected areas (MPAs) requires non-destructive observation methods. This is generally achieved by divers conducting underwater visual censuses (UVC), but video-based techniqu...

Development of laser ablation multi-collector inductively coupled plasma mass spectrometry for boron isotopic measurement in marine biocarbonates : ne...

Rationale: Laser Ablation coupled to Multi-Collector Inductively Coupled Plasma Mass Spectrometry (LA-MC-ICPMS) is a powerful tool for the high-precision measurement of the isotopic ratios of many elements in geological samples, with the isotope rati...

Limited interspecific variation in grazing susceptibility of the brown alga Lobophora to herbivory

The genus Lobophora is a notable benthic algal component of tropical coral reefs, capable of dominating large reef areas following coral mortality and herbivory declines. The alga, however, has been the object of contradictory observations in terms o...

Composition in essential and non-essential elements of early stages of cephalopods and dietary effects on the elemental profiles of Octopus vulgaris p...

During the present study, we aimed at providing a first look at the elemental composition of the early stages of cephalopods as an approach to their elemental requirements in culture. Essential and non-essential elemental profiles of the European cut...

Flower-visiting records of the native bees of New Caledonia

The flower-visiting records for the 43 species of bees considered to be native to New Caledonia show that females of 21 species visited 116 native species of plants in 69 genera and 41 families, and the bees were documented to carry pollen from 64 sp...

Incidence, correlates, and origins of dioecy in the Island Flora of New Caledonia

Premise of research. Because it is an inherently risky sexual system, dioecy is globally rare. Attempts to explain unusually high incidences of dioecy on certain islands have generated a considerable literature on the relationships among dioecy, its ...

Traditional banana diversity in Oceania: An endangered heritage

This study aims to understand the genetic diversity of traditional Oceanian starchy bananas in order to propose an efficient conservation strategy for these endangered varieties. SSR and DArT molecular markers are used to characterize a large sample ...

Whales in warming water : assessing breeding habitat diversity and adaptability in Oceania's changing climate

In the context of a changing climate, understanding the environmental drivers of marine megafauna distribution is important for conservation success. The extent of humpback whale breeding habitats and the impact of temperature variation on their avai...
