Phylogeny, classification and biogeography of Halfordia (Rutaceae) in Australia and New Caledonia

Halfordia F.Muell is a genus of rainforest trees or shrubs native to New Guinea, New Britain, New Caledonia, Vanuatu and eastern Australia. There is debate about the number of species that should be recognised in the genus. Four species have been nam...

Comparison of different genetic distances to test isolation by distance between populations

Studying isolation by distance can provide useful demographic information. To analyze isolation by distance from molecular data, one can use some kind of genetic distance or coalescent simulations. Molecular markers can often display technical caveat...

Progression in field infestation is linked with trapping of coffee berry borer, Hypothenemus hampei (Col., Scolytidae)

Phenology of the coffee plant and infestation by coffee berry borer #Hypothenemus hampei$ Ferrari were studied in relation to trapping of adult females in kairomone-baited traps in a coffee plantation in New Caledonia. In a 0.4 ha coffee field, a gro...

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...

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...

Increase in pelagic larval duration and geographical range for reef fish along an oceanic gradient

The structure of reef fish assemblages is known to vary according to numerous environmental factors, in particular reef type and coral cover. However little is known on the potential causes at the origin of species distribution along gradients in ree...

Study of nutritional requirements and growth of penaeus merguiensis in tanks by means of purified and artificial diets

One of the criteria for selecting a shrimp of commercial interest in French Polynesia is the acceptability of artificial diet; such a criterion has been used to test Penaeus merguiensis.Experiments have been carried out in Centre Océanologique du Pa...

Croissance et Société bleues : quels intérêts et perspectives pour la Nouvelle-Calédonie

This article calls back first of all a set of facts relative to the main stakes considering sea and ocean so much on the economic point of view, in the scientific technological and innovative fields, in the governance aspects as also in the culture a...

Are planktonic larvae of marine benthic invertebrates too scarce to compete within species?

Several models for the evolution of complex life histories have assumed a carrying capacity for both larval and postlarval stages. In addition, the densities of larvae in laboratory experiments are often so high that there is competition for food. Pu...
