Structure and genetic diversity of Ixora margaretae an endangered species

The dry forests of New Caledonia are an exceptional ecosystem because of their numerous endemic botanical species and their highly diversified fauna of insects, mollusks, reptiles and birds. Unfortunately, the area of the dry forests has been signifi...

Effect of the association of cattle and rusa deer Cervus timorensis russa on populations of cattle ticks (Boophilus microplus)

The wild population of rusa deer (Cervus timorensis russa) in New Caledonia (South Pacific) is nearly as large as the cattle population. The cattle tick is widespread and occurs all year round. Opinions are divided on the role of deer in the biologic...

Influence of mangrove zonation on CO2 fluxes at the sediment-air interface (New Caledonia)

Mangroves are the major ecosystems of tropical and subtropical coastlines. They are considered as a sink for atmospheric CO2 because they are characterized both by high net primary production, and by low rates of organic matter decomposition. However...

Biological data of pygmy killer whale (Feresa attenuata) from a mass stranding in New Caledonia (South Pacific) associated with hurricane Jim in 2006

Despite its distribution throughout the tropics and subtropics, the pygmy killer whale (Feresa attenuata) is one of the most poorly known species of odontocetes (Cetacea: Delphinidae). We used the opportunity of a mass stranding of six animals in New...
