Water mass analysis of the Coral Sea through an optimum multiparameter method

A water mass analysis of the Coral Sea thermocline waters provides a description of their distribution, pathways and mixture based on recent oceanographic cruises in this region of strong western boundary currents. The Optimum Multiparameter method i...

Genetic diversity and phylogeny of Aedes aegypti, the main arbovirus vector in the Pacific

Background The Pacific region is an area unique in the world, composed of thousands of islands with differing climates and environments. The spreading and establishment of the mosquito Aedes aegypti in these islands might be linked to human migration...

Phylogeography and niche modelling of the relict plant Amborella trichopoda (Amborellaceae) reveal multiple Pleistocene refugia in New Caledonia

Amborella trichopoda Baill. (Amborellaceae, Amborellales), the sole living member of the sister group to all other extant angiosperms, is endemic to New Caledonia. We addressed the intraspecific phylogeography of Amborella by investigating whether it...

Intermediate water flows in the western South Pacific : as revealed by individual Argo floats trajectories and a model re-analysis

Thanks to the autonomous Argo floats of the OUTPACE cruise (Oligotrophy to UlTra-oligotrophy PACific Experiment) and of the THOT (TaHitian Ocean Time series) project, some features of intermediate-flow dynamics, at around 1000 m depth, within t...

Changing ecological opportunities facilitated the explosive diversification of New Caledonian Oxera (Lamiaceae)

Phylogenies recurrently demonstrate that oceanic island systems have been home to rapid clade diversification and adaptive radiations. The existence of adaptive radiations posits a central role of natural selection causing ecological divergence and s...

Dynamique de la biodiversité et modalité d'accès aux milieux et aux ressources : séminaire de l'IFB, Fréjus, 7-9 septembre 2005

Sommaire : Avant-propos. Usages locaux et dynamique de la biodiversité : un thème de recherche interdisciplinaire, des enjeux cruciaux. Axe 1 : Interactions entre usages locaux et dynamique de la biodiversité : - Organisation de l'accès aux resso...

Les politiques de développement à l'épreuve de la territorialisation : changements et stabilités dans une situation de décolonisation négociée,...

Les dispositifs de développement territorial multiplient les territoires de gouvernance et les acteurs qui interviennent dans la fabrication de l'action publique. Cela pose la question des modalités d'interaction de ces acteurs dans leur diversité...

Monodominance at the rainforest edge: case study of Codia mackeeana (Cunoniaceae) in New Caledonia

Monodominance is unexpected in tropical forests, which usually exhibit rich and diverse flora. Mechanisms leading to monodominant forest are commonly discussed within the theoretical framework of forest succession. One of the central issues for manag...

Triassic Intracontinental Crustal Reworking of the Eastern Tianshan: New Insights From Late Triassic Adakitic and Low‐Sr/Y Granitoids in the Bogda R...

Abstract Continental intraplate magmatism remains a fundamental challenge in Plate Tectonics. Triassic magmatism represents a critical phase in the evolution of the Central Asian Orogenic Belt and continues to provoke debate about its tectonic settin...
