    Biodiversity theory backed by island bird data

    NEWS AND VIEWS 19 February 2020 Analysis of a unique global data set reveals how the species diversity of birds is affected by the properties of archipelagos and offers a way to test an influential theory. Has this improved our understanding of island biodiversity patterns. Kostas A. Triantis & Kostas A. Triantis is in the […] More

    Simulation-based reconstruction of global bird migration over the past 50,000 years

    Climate reconstruction Monthly climate data (temperature, precipitation and cloud cover) covering the past 50,000 years were obtained from the HadCM3 global circulation model46. These data are at 1000-year intervals between present and 22,000 years before present (BP) and at 2000-year intervals between 22,000 and 50,000 BP. The original simulation data on a 2.5° × 3.5° were bias […] More
