Colonization of coastal environments by foraminifera: insight from shrimp ponds in New Caledonia (sw Pacific)

The objectives of this study were to observe foraminiferal colonization patterns and behavior in shrimp ponds in New Caledonia during a shrimp-growing (farming) cycle. Weekly collecting at 10 stations in 8 shrimp ponds yielded a total of 170 samples ...

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 (...

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 ...

N-2 fixation as a dominant new N source in the western tropical South Pacific Ocean (OUTPACE cruise)

We performed nitrogen (N) budgets in the photic layer of three contrasting stations representing different trophic conditions in the western tropical South Pacific (WTSP) Ocean during austral summer conditions (FebruaryMarch 2015). Using a Lagrangian...

Age and growth of blackfin tuna (Thunnus atianticus) caught under moored fish aggregating devices, around Martinique Island

Daily growth increments measured in the otolith of Thunnus atlanticus were used to estimate the age and growth of individuals. which were sampled from an artisanal fishery operating around fish aggregating devices (FADs) moored off Martinique Island....
