Les enjeux globaux – le changement climatique, la réduction de la biodiversité, l’émergence de nouvelles pandémies, la sécurité alimentaire, les inégalités de genre et la lutte contre le terrorisme – nécessitent des solutions locales produites dans un contexte de limites planétaires. Les sciences de la connaissance et de l’innovation sont désormais sollicitées pour mieux évaluer les futurs dans lesquels nous pourrons vivre et trouver de nouvelles réponses, des appropriations locales, régionales et nationales. La recherche...

The oldest volcanic rocks exposed on Malekula Island, now belonging to the New Hebrides Island Arc, formed in the Upper Eocene to Middle Miocene Vitiaz Island Arc, Southwest Pacific. They are thought to have formed contemporaneously with Fiji and the Izu-Bonin-Mariana (IBM) arc during westward subduction initiation of the Pacific beneath the Indo-Australian Plate [e.g., 1]. To test this hypothesis with regard to the mantle source compositions and contributions from the subducting slab, we provide...

Invasions often accelerate through time, as dispersal-enhancing traits accumulate at the expanding range edge. How does the dispersal behaviour of individual organisms shift to increase rates of population spread? We collate data from 44 radio-tracking studies (in total, of 650 animals) of cane toads (Rhinella marina) to quantify distances moved per day, and the frequency of displacement in their native range (French Guiana) and two invaded areas (Hawai’i and Australia). Here we show that toads...
