Suivi des macro-invertébrés benthiques dans la zone d’activités de Vale NC - Campagne 1 de mars 2015 - Milieu lotique

Dans le cadre de son programme de suivi environnemental et conformément à la réglementation, la société VALE Nouvelle-Calédonie doit réaliser le suivi de la qualité biologique (macrofaune benthique) des cours d'eau présents dans la zon...

A simple and rapid device for measuring planktonic primary production by in situ sampling, and 14C injection and incubation

A system (LET GO) is described that enables measurements of primary production at sea after #in situ$ incubation, with 14C being injected at depth immediately after enclosure of the sample. Each incubation cell, about 200 ml, is made of two transpare...

Complément à la liste commentée des oiseaux de Nouvelle-Calédonie

Complement to the list of the birds of New Caledonia. Over the last five years, ten species of birds not previously known on the island have been seen, increasing the number of species/subspecies recorded in New Caledonia to about 192 taxa. Two of th...

Some forty species of scleractinian corals live in a particular, very muddy, environmment situated in the South-Western lagoon of New Caledonia between 25 and 30 metres depth. The seabed is caracterised by the topography of ridges valleys and bumps a...

Wave forcing and morphological changes of New Caledonia lagoon islets : insights on their possible relations

In the present study, we examine how waves may contribute to the morphological changes of islets in the New Caledonia lagoon. We collected in situ wave data to investigate their characteristics. Three types of waves are identified and quantified: (1)...

Sequential invasions by fruit flies (Diptera: Tephritidae) in Pacific and Indian Ocean islands: A systematic review

The aim of our review was to examine the cases of Tephritidae invasions across island systems in order to determine whether they follow a hierarchical mode of invasion. We reviewed the literature on factors and mechanisms driving invasion sequences i...

Hydrodynamic behaviour of Nummulites: implications for depositional models

Large benthic foraminifers are considered to be good indicators of shallow marine carbonate environments in fossil series. Over the last 50 years, the palaeoenvironment of Tertiary Nummulites accumulations has been a matter of debate, particularly be...

Penaeid reared brood stock : closing the cycle

Three shrimp species, Penaeus monodon, P. stylirostris (Panama and Mexican strains) and P. vannamei have matured and spawned in captivity at the Centre Océanologique du Pacifique (COP) laboratory. The shrimp, originally stocked as juveniles or postl...

Orama nui : a programme for an observatory of marine resources and activities in the Pacific Islands Countries

The "ORAMA NUI" programme has been developed by the Territory of French Polynesia and IFREMER, both partners in SPT since 1988. It first aims at alleviating some bottlenecks, mainly in the coastal and lagoon economic development process, by use of sa...

Rapid and sensitive PCR detection of Vibrio penaeicida, the putative etiological agent of syndrome 93 in New Caledonia

Experimental infections of Penaeus (Litopenaeus) stylirostris were performed with a Vibrio penaeicida strain (AM101) isolated in New Caledonia from Syndrome 93 diseased shrimp. Cumulative mortalities resulting from intramuscular injection or immersio...
