  • Discovery of the oldest mammal in Brazil pays tribute to David Bowie
    on June 11, 2018 at 5:33 pm

    Brasilestes stardusti lived around 70 million years ago and was named after Ziggy Stardust, the singer's iconic persona. Description was based on a fossilized tooth. It's the 1st indication that placental mammals and dinosaurs co-existed in South America. For scientists, fossil features showed similarities with another pre-historic mammal found in India, suggesting both shared a common ancestral native from the Gondwana supercontinent. […]

  • Secrets of fish population changes revealed
    on June 8, 2018 at 2:19 pm

    Populations of fish in the ocean are notoriously variable, waxing and waning in often unpredictable ways. Knowing what drives changes in fish population sizes is important for managing fisheries and conserving species. For the first time, scientists have linked the ecology of adult fish populations inhabiting coral reefs with the dispersal of baby fish between reefs, reporting the dynamics of a living network called a 'marine metapopulation.' […]

  • Toxic toad invasion puts Madagascar's predators at risk, genetic evidence confirms
    on June 4, 2018 at 3:26 pm

    The recent introduction of the common Asian toad to Madagascar has led to fears that the toxic amphibian could wreak havoc on the island's already severely threatened fauna. Now, researchers report genetic evidence showing that those fears are well founded: virtually all predators native to Madagascar are highly sensitive to toad toxins. If they should eat the toads, it would be a potentially fatal mistake. […]
