    La fonte de la biodiversité dans les îles : modélisation de l’impact du réchauffement global sur la végétation orophile de Tahiti (Polynésie française) by Robin Pouteau, Jean-Yves Meyer, Ravahere Taputuarai, Benoît Stoll

    Published 2010-12-01
    “…Consequences on biodiversity will be : (i) the loss of a unique ecosystem in French Polynesia, the subalpine zone, and the extinction of, at least, six plant species restricted to this habitat and endemic to Tahiti ; (ii) the loss and fragmentation of the cloud forests, which will only be found on the highest summits, leading to an additional risk of extinction ; and (iii) the expansion of alien invasive species, having already an enormous ecological impact in Tahiti.…”
