Étude du statut et de la distribution des oiseaux des forêts humides de la Province Sud de la Nouvelle-Calédonie - Rapport final.

Étude ayant pour but de dégager des priorités en terme de conservation du patrimoine avifaunistique de la Nouvelle-Calédonie en étudiant le statut et la distribution des oiseaux des forêts humides et les menaces qui s'exercent sur eux.

Systematics and evolution of New Caledonian Araucaria

Ce rapport de thèse étudie la systématique et la phylogénie du genre Araucaria en Nouvelle-Calédonie. 238 pages.thèse sur la systématique et l'évolution des résineux du genre Araucaria en Nouvelle-Calédonie

Prolifération d'espèces animales ou végétales

Une espèce, animale ou végétale, est dite envahissante lorsqu'elle prolifère et entre en concurrence avec les espèces natives. Elle prend alors la place des autres espèces et devient largement dominante, déséquilibrant tout l'écosystème. D...

Lack of nucleotide variability in a beetle pest with extreme inbreeding

The coffee berry borer beetle #Hypothenemus hampei$ (Ferrari) (#Curculionidae$ : #Scolytinae$) is the major insect pest of coffee and has spread to most of the coffee-growing countries of the world. This beetle also displays an usual life cycle, with...

Maturation and spawning in captivity of penaeid shrimps

As no indigenous species of commercial penaeid shrimp live in the waters of French Po1ynesia, the pre1iminary step in deve10ping shrimp aquaculture was to obtain maturation and spawning in captivity. Five species have been investigated. Wi1d-caught j...

Activité magmatique, tectonique et hydrothermale actuelle sur la Dorsale Est Pacifique entre17°-et 19°S(campagne NAUDUR)

The submersible-study of four segments of the East Pacific Rise between 17 degrees and 18 degrees 40'S, where the spreading rate is greater than 150 mm/a, allows us to confirm the variability of the accretion processes. The segment between 17 degrees...

Small-scale FADs-associated fishing techniques used in the Pacific region

Over the last 16 years, the Secretariat of the Pacific Community (SPC - formerly the South Pacific Commission) has been developing and providing information on mid-water fishing techniques targeting the larger, deeper-swimming tunas that aggregate ar...

Experimental study of the turbulence intensity effects on marine current turbines behaviour. Part II: Two interacting turbines

The future implantation of second generation marine current turbine arrays depends on the understanding of the negative interaction effects that exist between turbines in close proximity. This is especially the case when the turbines are axially alig...

Physiological responses of female and male black-lip pearl oysters (Pinctada margaritifera) to different temperatures and concentrations of food

This study was designed to measure responses of four-year-old black-lip pearl oysters (Pinctada margaritifera) to different temperatures and food concentrations and to identify the energy requirements of each sex. Oysters were fed a monospecific micr...

Phytoplankton dynamics in the southern New Caledonian lagoon during a southeast trade winds event

During the Echolag cruise (13 February-8 March 2007), the effect of 16-30 knot trade winds on abundance, community structure and dynamics of phytoplankton was investigated in the southern part of the New Caledonian coral reefs and surrounding oceanic...
