Etude de la diversité génétique chez Santalum austrocaleclonicum de Nouvelle-Calédonie par la technique random amplified polymorphie DNA(RAPD)

Le santal, petit arbre répandu dans l'aire pacifique s'étendant de l'Inde à l'Amérique du sud, est réputé pour l'huile essentielle obtenue par distillation de son bois de coeur. Cette substance utilisée dans de nombreux produits (encens, ongue...

Systèmes d'exploitation en pêche côtière ; méthode d'étude et application au cas des Pertuis

This report presents a functional typology of the exploitation systems of fisheries in the Charentais sounds. It describes the nature of such a typology as well as the method developed in relation to the topic of the study. The determination and form...

Pathogenicity of Vibrio penaeicida or white shrimp Litopenaeus vannamei: a cysteine protease-like exotoxin as a virulence factor

The pathogenicity of Vibrio penaeicida Strains KH-1 and AM101, their culture-free supernatant (CFS), and their protein fraction obtained by 40% of ammonium sulfate precipitation (PFs40) were assessed in experimental challenges against juvenile Litope...

Modélisation en 3D du bassin d'essais d'engins de pêche de la station de Lorient

3D modelling of the fishing gear flume tank at IFREMER's Lorient site Within the framework of their training, it is suggested that students in their first year of the "Industrial Product Design" BTS (vocational training certificate) at the Colbert de...

Ongoing geographical spread of Tomato yellow leaf curl virus

Tomato yellow leaf curl virus (TYLCV) seriously impacts tomato production throughout tropical and sub-tropical regions of the world. It has a broad geographical distribution and continues to spread to new regions in the Indian and Pacific Oceans incl...

Stratégies de lutte contre la tique du bétail en Nouvelle-Calédonie. Synthèse des connaissances

La tique du bétail introduite sur le territoire en provenance d'Australie lors de la Seconde Guerre mondiale, constitue une des principales contraintes de l'élevage bovin. Elle génère des pertes économiques qui peuvent être insupportables pour ...

Vallitalea pronyensis sp nova, isolated from a marine alkaline hydrothermal chimney

A novel thermotolerant, anaerobic, Gram-stain-positive, spore-forming bacterium was isolated from a hydrothermal chimney in Prony Bay, New Caledonia. This strain, designated FatNl3(T), grew at 15-55 degrees C (optimum 30 degrees C) and at pH 5.8-8.9 ...

Segregation in diet between Black Noddy (Anous minutus) and Brown Noddy (A. stolidus) from the southern lagoon of New Caledonia

The Black Noddy (Anous minutus) and the Brown Noddy (A. stolidus) occur sympatrically in the Southern Lagoon of New Caledonia, breeding on islets located at the edge of a wide, productive coral-reef lagoon next to oceanic waters enriched by a seasona...

Colonization and release processes of viruses and prokaryotes on artificial marine macroaggregates

Marine organic aggregates are sites of high of viral accumulation; however, still little is known about their colonization processes and interactions with their local bacterial hosts. By taking advantage of a novel approach (paramagnetic functionaliz...

Etude des tris précoces en élevage de crevettes P. stylirostris dans un objectif de sélection génétique. Février à Juillet 2000.

Schemes optimisation for genetic improvement for growth of Penaeus stylirostris requires the development of technologies for grading shrimps easily. This work shows that bar and mesh graders are very suitable for early selection at post-larval stages...
