  • Solving Darwin's 'abominable mystery': How flowering plants conquered the world
    on January 11, 2018 at 7:17 pm

    Researchers have found that flowering plants have small cells relative to other major plant groups, made possible by a greatly reduced genome size, and this may explain how they became dominant so rapidly in ecosystems across the world. […]

  • Protecting corridors is critical to preserving genetic diversity in tigers, and mizimising...
    on January 11, 2018 at 3:14 pm

    Tigers have lost 95% of their historical range, and what remains is highly fragmented. According to a new study, high traffic roads and densely populated urban areas are a severe impediment to tiger movement between fragments. Unplanned development in the future will result in loss of connectivity and an increased possibility of extinction for several tiger populations. To ensure future persistence, tiger populations need to be managed as a network of protected areas connected by corridors. […]

  • The ecological costs of war: Conflict a consistent killer of African megafauna
    on January 10, 2018 at 6:15 pm

    Researchers report that war has been a consistent factor in the decades-long decline of Africa's large mammals. But the researchers also found that wildlife populations rarely collapsed to the point where recovery was impossible, meaning that even protected areas severely affected by conflict are promising candidates for conservation and rehabilitation efforts. […]

  • Life on land and tropical overheating 250 million years ago
    on January 10, 2018 at 2:49 am

    One of the key effects of the end-Permian mass extinction, 252 million years ago, was rapid heating of tropical waters and atmospheres. How this affected life on land has been uncertain until now. New research shows how early reptiles were expelled from the tropics. […]

  • Mass extinctions remove species but not ecological variety
    on January 9, 2018 at 5:49 pm

    Though mass extinctions wiped out staggeringly high numbers of species, they barely touched the overall 'functional' diversity -- how each species makes a living, be it filtering phytoplankton or eating small crustaceans, burrowing or clamping onto rocks. […]

  • Dead trees are alive with fungi
    on January 9, 2018 at 4:24 pm

    So far, little research has been conducted on fungi that live on dead trees, although they are vital to the forest ecology by breaking down dead wood and completing the element cycle between plants and soil. Soil biologists have now discovered that the number of fungus species inhabiting dead trees is 12 times higher than previously thought. Once trees die they are also colonized by different fungal communities depending on their species. […]

  • Amazon biodiversity hotspot to suffer even more losses after contentious law passed
    on January 8, 2018 at 5:16 pm

    In August 2017, the Bolivian government passed a contentious law that paved the way for construction of a new 190-mile road cutting through one of the country's most iconic and biodiverse protected rainforests. But a new report shows that the Isiboro-Sécure National Park and Indigenous Territory (or TIPNIS) has been subject to alarming levels of deforestation within its borders for many years, a reality that is too often overlooked.
