    Primary-tiller panicle number is critical to achieving high grain yields in machine-transplanted hybrid rice

    Field experiments were conducted in Yongan (28°09′N, 113°37′E, 43 m asl), Hunan Province, China in the late rice-growing season in 2017 and 2018. The site has a moist subtropical monsoon climate. Average daily solar radiation and mean temperature during the rice-growing season were 12.9 MJ m−2 d−1 and 25.7 °C in 2017 and 15.1 MJ m−2 d−1 […] 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
