Ecologie trophique de la tortue verte Chelonia mydas dans les herbiers marins et algueraies du sud-ouest de l’océan Indien ArchiMer
Ballorain, Katia.
Reproduction of sea turtles primarily relies on body reserves stored during the time spent on foraging grounds prior to the nesting season. Accordingly, the investigation of foraging behaviour of sea turtles is critical for better assessing their biology but also for conservation issues of these endangered species. Sea turtles contribute significantly to the consuming biomass of their ecosystem and hence to its functioning, thus providing natural indications of the health of the ecosystem. Yet the trophic ecology of sea turtles is poorly documented because their feeding grounds remain poorly known and for most of them hardly accessible. Among sea turtles the green turtle is the only species where sub-adults and adults are mostly herbivorous feeding on...

L'espadon : de la recherche à l'exploitation durable ArchiMer
Poisson, Francois; Taquet, Marc.
Contrary to the situation in Europe, Réunion Island is the only French department whose fishing has increased considerably for five years, as far as artisanal fishing linked to DCPs (Fish Concentration Plans), but also semi-industrial longline fishing and industrial fishing in southern oceans are concerned. Two capital events contribute to the quick development of tuna fishing and provide Reunion Island with access to its pelagic resources. The setting up in 1988 of the first DCPs by the French Research institute for the exploitation of the sea (Ifremer) resulted in a real upheaval of artisanal fishery and relaunched a sector which had been slowing down since 1980. In 1991, witnessing the success of Asian longline boats unloading on Reunion Island, a local...

Projet "HYDRORUN" : Etat d'avancement du projet Ifremer-OIHYDRORUN. Première année (2010) ArchiMer
Ropert, Michel; Lazure, Pascal.
La phase opérationnelle du projet HYDRORUN, initié fin 2009, a débuté en avril 2010. A l'échéance de fin 2012, HYDRORUN devrait proposer aux décideurs et aux acteurs du littoral Réunionnais de nouveaux outils d'aide à la décision en matière de préservation et de gestion de la qualité des eaux littorales. Ces outils reposent sur une plate-forme de modélisation hydrodynamique centrée sur 6 modèles mars 3d, à mailles de 100 m, couvrant l'ensemble du littoral de l'île de La Réunion. Au terme de la première année du projet, le travail réalisé avec les différents partenaires du projet est présenté. Les emprises des modèles locaux ont été définies. Les données historiques de références ont été rassemblées. Les modèles atmosphériques et les modèles de houles sont...

Re-shaping Mallotus [Part 1]: Expanded circumscription and revision of the genus Cordemoya (Euphorbiaceae) Naturalis
Sierra, S.E.C.; Aparicio, M.; Kulju, K.K.M.; Fišer, Ž.; Welzen, P.C. van; Ham, R.W.J.M. van der.
A recent phylogenetic study based on DNA sequence data detected a well-supported clade of a number of Mallotus species together with the genus Cordemoya. This clade is distinct from the large Mallotus s.s. clade. In this paper, Cordemoya (formerly monotypic with C. integrifolia from the Mascarene Islands) is expanded with sixteen additional species previously assigned to Mallotus. Taxa transferred to Cordemoya are: Mallotus sections Hancea and Oliganthae from Asia and M. baillonianus, M. capuronii, and M. spinulosus from Madagascar. The genus Cordemoya can be distinguished from Mallotus s.s. by the presence of pollen with areolate ornamentation with scabrae (perforate/microreticulate ornamentation with scabrae in the sample of Mallotus s.s. studied up to...

Technologie des dispositifs de concentration de poissons et techniques de pêche aux gros pélagiques. Compte rendu d'essais effectués pendant l'été austral 1989-90 ArchiMer
Biais, Gerard; Taquet, Marc.
Fish aggreagating devices (FAD), "semi-heavy" models, have been anchored all around La Réunion Island since 1988. For maximising profits derived from them, "light" FAD less expensive have been designed and locally unused fishing gears were tried. The use of this latter appears to be limited in local context, but in contrast the use of "light" FADS seems an interesting way. Their design calculus are given. NOT CONTROLLED OCR
