Observer, évaluer et suivre la biodiversité sous marine des lagons : Intérêt des techniques vidéo rotatives en haute dé:nition. Où en est-on en...

This article first draws up a balance sheet of all various implemented techniques to observe and monitor the shallow marine biodiversity. Then the article focuses on the techniques of the rotating high resolution submarine video and their implementat...

Rapid and sensitive PCR detection of Vibrio penaeicida, the putative etiological agent of syndrome 93 in New Caledonia

Experimental infections of Penaeus (Litopenaeus) stylirostris were performed with a Vibrio penaeicida strain (AM101) isolated in New Caledonia from Syndrome 93 diseased shrimp. Cumulative mortalities resulting from intramuscular injection or immersio...

Diet and gut microorganisms of Munidopsis squat lobsters associated with natural woods and mesh-enclosed substrates in the deep South Pacific

Squat lobsters of the deep-sea genus Munidopsis are among the most regularly reported crustaceans associated with deep-sea wood falls. They are often thought to indirectly use these substrates for preying or scavenging wood-associated molluscs or ann...

How accessible are coral reefs to people ? A global assessment based on travel time

The depletion of natural resources has become a major issue in many parts of the world, with the most accessible resources being most at risk. In the terrestrial realm, resource depletion has classically been related to accessibility through road net...

Hydrodynamic behaviour of Nummulites: implications for depositional models

Large benthic foraminifers are considered to be good indicators of shallow marine carbonate environments in fossil series. Over the last 50 years, the palaeoenvironment of Tertiary Nummulites accumulations has been a matter of debate, particularly be...

Progrès technologiques au sein des industries alimentaires. Impact sur la qualité des produits

This study has been carried out on behalf of the Technology Academy in the framework of a number of works aiming to characterize the impact of the evolution of production and transformation technologies on the sanitary, nutritional and organoleptic q...

Penaeid reared brood stock : closing the cycle

Three shrimp species, Penaeus monodon, P. stylirostris (Panama and Mexican strains) and P. vannamei have matured and spawned in captivity at the Centre Océanologique du Pacifique (COP) laboratory. The shrimp, originally stocked as juveniles or postl...

Combining the Biocean database for deep-sea benthic data with the online Ocean Biogeographic Information System

The Biocean database was designed to collate the extremely large volume of data collected from different deep-sea ecosystem studies conducted by Ifremer's department of 'Environnement Profond' (Deep-Sea Environment). This database comes in a 6-applic...

Wave forcing and morphological changes of New Caledonia lagoon islets : insights on their possible relations

In the present study, we examine how waves may contribute to the morphological changes of islets in the New Caledonia lagoon. We collected in situ wave data to investigate their characteristics. Three types of waves are identified and quantified: (1)...

Environmental DNA illuminates the dark diversity of sharks

In the era of "Anthropocene defaunation," large species are often no longer detected in habitats where they formerly occurred. However, it is unclear whether this apparent missing, or "dark," diversity of megafauna results from local species extirpat...
