Mycorrhizal symbioses : their potential for soil rehabillitation and ecological restoration

In New Caledonia, nickel mining activities have drastic impacts on a rich but particularly fragile environment. Mining companies are more and more concerned with the need to restore the degraded sites, in adverse edaphic conditions. Symbioses, both n...

Progression in field infestation is linked with trapping of coffee berry borer, Hypothenemus hampei (Col., Scolytidae)

Phenology of the coffee plant and infestation by coffee berry borer #Hypothenemus hampei$ Ferrari were studied in relation to trapping of adult females in kairomone-baited traps in a coffee plantation in New Caledonia. In a 0.4 ha coffee field, a gro...

Effects of elevated atmospheric CO2 and increased tidal flooding on leaf gas-exchange parameters of two common mangrove species: Avicennia marina and ...

In this study, we examined interactive effects of elevated atmospheric CO2, concentrations, and increased tidal flooding on two mangroves species, Avicennia marina and Rhizophora stylosa. Leaf gas-exchange parameters (photosynthesis, transpiration ra...

In this study, we examined interactive effects of elevated atmospheric CO2, concentrations, and increased tidal flooding on two mangroves species, Avicennia marina and Rhizophora stylosa. Leaf gas-exchange parameters (photosynthesis, transpiration ra...

Slowing taxon cycle can explain biodiversity patterns on islands: Insights into the biogeography of the tropical South Pacific from molecular data

Islands in the tropical Pacific Ocean are renowned for high biodiversity and endemism despite having relatively small landmasses. However, our knowledge of how this biodiversity is formed remains limited. The taxon cycle, where well-dispersed, earlie...

Connectivity of horse hoof giant clam, Hippopus hippopus in the North-East Lagoon of New Caledonia

Ce rappport traite de la connectivité du bénitier rouleur dans le lagon nord-est de la Nouvelle-Calédonie.

Connectivity of horse hoof giant clam, Hippopus hippopus in the North-East Lagoon of New Caledonia

Poster illustrant une étude sur l'estimation de la connectivité des populations du bénitier rouleur Hippopus hippopus dans le lagon Nord-Est de Nouvelle-Calédonie.

Increase in Growth and Alteration of C:N Ratios of Avicennia marina and Rhizophora stylosa Subject to Elevated CO2 Concentrations and Longer Tidal Flo...

We investigated the effects of elevated CO2 concentrations and longer tidal flooding duration on two-year-old Avicennia marina and Rhizophora stylosa seedlings for a full year. The seedlings were grown in greenhouses for ambient CO2 (400 ppm) and in ...

Effect of dietary probiotic Pediococcus acidilactici on antioxidant defences and oxidative stress status of shrimp Litopenaeus stylirostris

in this study we evaluated the effects of the probiotic Pediococcus acidilactici MA18/5M on shrimp, Litopenaeus stylirostris (also called Penaeus stylirostris), first on antioxidant defences and secondly on the oxidative stress status in the shrimps'...

Proteinaceous exotoxins of shrimp-pathogenic isolates of Vibrio penaeicida and Vibrio nigripulchritudo

The pathogenicity of two V. penaeicida strains, AM101 and KH-1, with different geographic origin, and V. nigripulchritudo strain AM102, were investigated in juvenile blue shrimp species Litopenaeus stylirostris. Alive bacteria and protein fractions (...
