Polyopisthocotylean monogeneans from carangid fishes off Queensland, Australia and New Caledonia, with a description of Heteromicrocotyloides megaspin...

Gills of carangid fishes in Australian waters are dominated by a diversity of polyopisthocotylean monogeneans. This study updates current knowledge of polyopisthocotyleans from carangid hosts in waters along the Queensland coast of Australia and also...

New data on dracunculoid nematodes from fishes off New Caledonia, including four new species of Philometra (Philometridae) and Ichthyofilaria (Guyanem...

Recent examinations of newly obtained materials of dracunculoid nematodes (Dracunculoidea) parasitizing marine fishes off New Caledonia, South Pacific, revealed the presence of several nematodes of the genera Philometra Costa, 1845 (Philometridae) an...

Three new species of Planchonella Pierre (Sapotaceae) with a dichotomous and an online key to the genus in New Caledonia

In spite of a recent publication of eight new species of Planchonella (Sapotaceae) from New Caledonia, three additional novelties are here described and illustrated (P. cauliflora, P. ericiflora, and P. minutiflora). Planchonella cauliflora was disco...

Structure and development of the southeast Newfoundland continental passive margin: derived from SCREECH Transect 3

P>New seismic reflection data from the Grand Banks of Newfoundland and the Newfoundland Basin add to the growing knowledge of the composition, structure and history of this non-volcanic margin. Geophysical imaging is now approaching the extent of tha...

Archaeal communities associated with shallow to deep subseafloor sediments of the New Caledonia Basin

P>The distribution of the archaeal communities in deep subseafloor sediments [0-36 m below the seafloor (mbsf)] from the New Caledonia and Fairway Basins was investigated using DNA- and RNA-derived 16S rRNA clone libraries, functional genes and denat...

Geophysical characterization of bottom simulating reflectors in the Fairway Basin (off New Caledonia, Southwest Pacific), based on high resolution sei...

High-resolution reflection and refraction seismic data were collected in 2004 to investigate, in further detail than allowed by pre-existing low resolution seismic data, the nature of a Bottom Simulating Reflector (BSR) that extends over a broad area...

Chromis durvillei : une nouvelle espèce de Pomacentridae de l’île de la Réunion (France, océan Indien) et premier signalement pour l’île de C...

Following the volcanic eruption of April 2007 at Reunion Island, 12 specimens of the pomacentrid genus Chromis were collected at sea surface. One of these fishes was a C. chrysura known from the reef Island fauna. The others have enlarged eyes. Among...

Considering multiple-species attributes to understand better the effects of successive changes in protection status on a coral reef fish assemblage

The response of fish assemblages to changes in protection status is a major issue for both biodiversity conservation and fishery management. In New Caledonia, the Abore reef marine reserve harbours more than 500 fish species, and has been subjected t...

Mesozoic history of the Fairway-Aotea Basin: Implications for the early stages of Gondwana fragmentation

The Fairway Ridge is a buried continental structure that separates the Fairway Basin from the New Caledonia Basin. The proposed Cretaceous age of the Fairway Basin has remained highly hypothetical to date. Deep offshore petroleum exploration wells re...

jeu de l'octoquiz

Il s'agit d'un jeu ludique au travers duquel 8 questions sont posées. Ces questions permettent d'aborder différentes problématiques telles que les espèces envahissantes, l'acidification des océans, la dégradation des sols...
