Is it possible to raise, offspring of the 25th generation of Litopenaeus vannamei (Boone) and 18th generation Litopenaeus stylirostris (Stimpson) in c...

Peneid shrimp are commonly reared in clear-water aquaria or tanks for short-term studies of 4-6 weeks during controlled experiments, such as nutrition studies to estimate dietary nutrient requirements. Recently, in line with the genetic program at Ce...

Can we use the planation surface concept to reconstruct the morphogenesis of New Caledonia,? First low temperature thermochronological data

Nickel ore deposits of New Caledonia are formed in thick laterites and ferricretes developed on peridotites. Formation of this regolith remains unclear but combines stable phases with weathering profile development and preservation and mobile phases ...

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...

Ecology and biodiversity of the symbiosis Frankia-Casuarinaceae in New Caledonia;Deuxième conférence internationale sur l'écologie des milieux serp...

The native region of #Casuarinaceae$ family (actinorhizal plants) is Oceania (Australia and Indo-Pacific islands). In New Caledonia, in spite of the reduced area, a great number of endemic #Casuarinaceae$ are present. In fact, 8 species of #Gymnostom...

Effect of the association of cattle and rusa deer Cervus timorensis russa on populations of cattle ticks (Boophilus microplus)

The wild population of rusa deer (Cervus timorensis russa) in New Caledonia (South Pacific) is nearly as large as the cattle population. The cattle tick is widespread and occurs all year round. Opinions are divided on the role of deer in the biologic...

Genetic diversity and population structure of an insular tree, Santalum austrocaledonicum in New Caledonian archipelago

We present a study of the genetic diversity and structure of a tropical tree in an insular system. Santalum austrocaledonicum is endemic to the archipelago of New Caledonia and is exploited for oil extraction from heartwood. A total of 431 individual...

Molecular markers to assess genetic diversity and population structure of an insular tree Santalum austrocaledonicum in New Caledonian archipelago

We present the study of the genetic diversity and structure of a tropical tree in an insular system, using nuclear and chloroplastic microsatellites. Santalum austrocaledonicum is endemic to the archipelago of New Caledonia and is exploited for oil e...

Spatial distribution of small pelagic fish in the lagoon of New Caledonia;Proceedings of the 6th international coral reef symposium

Two acoustic surveys have been done in the lagoon all around New Caledonia, with a digital integrator. The cruises lasting two weeks were done at six month interval. Much information has been obtained on stock biomass and spatial distribution of fish...

Molecular phylogenetics of New Caledonian Diospyros (Ebenaceae) using plastid and nuclear markers

To clarify phylogenetic relationships among New Caledonian species of Diospyros, sequences of four plastid markers (atpB, rbcL, trnKmatK and trnStrnG) and two low-copy nuclear markers (ncpGS and PHYA) were analysed. New Caledonian Diospyros species f...

Resurrection of New Caledonian maskray Neotrygon trigonoides (Myliobatoidei : Dasyatidae) from synonymy with N. kuhlii, based on cytochrome-oxidase I ...

The maskray from New Caledonia, Neotrygon trigonoides CasteInau, 1873, has been recently synonymized with the blue-spotted maskray, N. kuhlii (Muller and Henle, 1841), a species with wide Indo-West Pacific distribution, but the reasons for this are u...
