Earliest Eocene (53 Ma) convergence in the Southwest Pacific; evidence from pre-obduction dikes in the ophiolite of New Caledonia.

Uncertainty about timing and location of the initiation of convergence in the western and south western Pacific greatly hinders accurate plate tectonic reconstructions of subduction systems in that area. The chemistry and age of dikes intruding mantl...

Research on citrus fruit varieties

Citrus-fruit farming only developed recently in New Caledonia. Although the Tristeza virus was accidentally introduced from Australia at the beginning of the 1960s, the island benefits from a relatively favourable phytosanitary situation (I.e, no Gre...

Germination of two provenances of Santalum austrocaledonicum var. austrocaledonicum

During the germination phase of a #Santalum austrocaledonicum# progeny trial, important and unexpected differences occurred in the germination rates between two provenances. The "Ile des Pins" provenance conformed with expectations, previous experime...

Animal leptospirosis in small tropical areas

Leptospirosis is the most widespread zoonosis in the world. Humans become infected through contact with the urine of carrier animals, directly or via contaminated environments. This review reports available data on animal leptospirosis in ten tropica...
