Concentrations en chlorophylle dans le Pacifique tropical sud-ouest : comparaison avec d'autres aires océaniques tropicales

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...

The Percy Sladen Trust expedition to the Indian ocean in 1905 - Vol. 8

This paper deals with the CIIDAE* collected by the Percy Sladen Trust Expedition to the Indian Ocean under Professor J. Stanley Gardiner, F.R.S., in 1908-9. Twenty species of these beetles were obtained, eighteen in the Seychelles only, one in both t...

An updated checklist of the marine fish fauna of Reunion Island, South-Western Indian Ocean

The ichthyofauna of Reunion Island, Southwestern Indian Ocean, was sampled during several ecological and artisanal fisheries studies. Information from these investigations and from other sources were included to compile the present checklist of the m...

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...

Notes on the biology of the bigeye scad, Selar crumenophthalmus (Carangidae) around Reunion Island, southwest Indian Ocean

The main characteristics of the biology of bigeye scad were studied from commercial fishery catches around Reunion Island. Biometric relationships were calculated. The monitoring of size distribution, aggregated by month, allowed us to estimate the t...

L'élévation récente du niveau marin et l'érosion côtière : le cas d'îles océaniques du Pacifique

Le changement climatique induit une élévation du niveau marin qui, loin d'être uniforme, présente une variabilité régionale importante liée en premier lieu aux variations de température des océans. Dans certaines régions de l'océan, cette ...

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...

Sequential invasions by fruit flies (Diptera: Tephritidae) in Pacific and Indian Ocean islands: A systematic review

The aim of our review was to examine the cases of Tephritidae invasions across island systems in order to determine whether they follow a hierarchical mode of invasion. We reviewed the literature on factors and mechanisms driving invasion sequences i...

Determining the age of tropical tunas in the Indian Ocean from otolith microstructures

The Indian Ocean Tuna Tagging Program (IOTTP) provided a unique opportunity to assess the viability of estimating the age of tropical tunas from the micro-structural features of otoliths. Here, we analyzed the length measurements and micro-increment ...
